A mortgage loan is a loan secured by real property through the use of a mortgage note which evidences the existence of the loan and theencumbrance of that realty through the granting of a mortgage which secures the loan. However, the word mortgage alone, in everyday usage, is most often used to mean mortgage loan.

A home buyer or builder can obtain financing (a loan) either to purchase or secure against the property from a financial institution, such as a bank, either directly or indirectly through intermediaries. Features of mortgage loans such as the size of the loan, maturity of the loan, interest rate, method of paying off the loan, and other characteristics can vary considerably.

In many jurisdictions, though not all (Bali, Indonesia being one exception^[1]), it is normal for home purchases to be funded by a mortgage loan. Few individuals have enough savings or liquid funds to enable them to purchase property outright. In countries where the demand for home ownership is highest, strong domestic markets have developed.

The word mortgage is a Law French term meaning "dead pledge," apparently meaning that the pledge ends (dies) either when the obligation is fulfilled or the property is taken through foreclosure.^[2]

Mortgage loan basics

[edit]Basic concepts and legal regulation

According to Anglo-American property law, a mortgage occurs when an owner (usually of a fee simple interest in realty) pledges his or her interest (right to the property) as security orcollateral for a loan. Therefore, a mortgage is an encumbrance (limitation) on the right to the property just as an easement would be, but because most mortgages occur as a condition for new loan money, the word mortgage has become the generic term for a loan secured by such real property.^[3]

As with other types of loans, mortgages have an interest rate and are scheduled to amortize over a set period of time, typically 30 years. All types of real property can be, and usually are, secured with a mortgage and bear an interest rate that is supposed to reflect the lender's risk.

Mortgage lending is the primary mechanism used in many countries to finance private ownership of residential and commercial property (see commercial mortgages). Although the terminology and precise forms will differ from country to country, the basic components tend to be similar:

• Property: the physical residence being financed. The exact form of ownership will vary from country to country, and may restrict the types of lending that are possible.
• Mortgage: the security interest of the lender in the property, which may entail restrictions on the use or disposal of the property. Restrictions may include requirements to purchasehome insurance and mortgage insurance, or pay off outstanding debt before selling the property.
• Borrower: the person borrowing who either has or is creating an ownership interest in the property.
• Lender: any lender, but usually a bank or other financial institution. Lenders may also be investors who own an interest in the mortgage through a mortgage-backed security. In such a situation, the initial lender is known as the mortgage originator, which then packages and sells the loan to investors. The payments from the borrower are thereafter collected by a loan servicer.^[4]
• Principal: the original size of the loan, which may or may not include certain other costs; as any principal is repaid, the principal will go down in size.
• Interest: a financial charge for use of the lender's money.
• Foreclosure or repossession: the possibility that the lender has to foreclose, repossess or seize the property under certain circumstances is essential to a mortgage loan; without this aspect, the loan is arguably no different from any other type of loan.

Many other specific characteristics are common to many markets, but the above are the essential features. Governments usually regulate many aspects of mortgage lending, either directly (through legal requirements, for example) or indirectly (through regulation of the participants or the financial markets, such as the banking industry), and often through state intervention (direct lending by the government, by state-owned banks, or sponsorship of various entities). Other aspects that define a specific mortgage market may be regional, historical, or driven by specific characteristics of the legal or financial system.

Mortgage loans are generally structured as long-term loans, the periodic payments for which are similar to an annuity and calculated according to the time value of money formulae. The most basic arrangement would require a fixed monthly payment over a period of ten to thirty years, depending on local conditions. Over this period the principal component of the loan (the original loan) would be slowly paid down through amortization. In practice, many variants are possible and common worldwide and within each country.

Lenders provide funds against property to earn interest income, and generally borrow these funds themselves (for example, by taking deposits or issuing bonds). The price at which the lenders borrow money therefore affects the cost of borrowing. Lenders may also, in many countries, sell the mortgage loan to other parties who are interested in receiving the stream of cash payments from the borrower, often in the form of a security (by means of a securitization).

Mortgage lending will also take into account the (perceived) riskiness of the mortgage loan, that is, the likelihood that the funds will be repaid (usually considered a function of the creditworthiness of the borrower); that if they are not repaid, the lender will be able to foreclose and recoup some or all of its original capital; and the financial, interest rate risk and time delays that may be involved in certain circumstances.

[edit]Mortgage loan types

There are many types of mortgages used worldwide, but several factors broadly define the characteristics of the mortgage. All of these may be subject to local regulation and legal requirements.

• Interest: interest may be fixed for the life of the loan or variable, and change at certain pre-defined periods; the interest rate can also, of course, be higher or lower.
• Term: mortgage loans generally have a maximum term, that is, the number of years after which an amortizing loan will be repaid. Some mortgage loans may have no amortization, or require full repayment of any remaining balance at a certain date, or even negative amortization.
• Payment amount and frequency: the amount paid per period and the frequency of payments; in some cases, the amount paid per period may change or the borrower may have the option to increase or decrease the amount paid.
• Prepayment: some types of mortgages may limit or restrict prepayment of all or a portion of the loan, or require payment of a penalty to the lender for prepayment.

The two basic types of amortized loans are the fixed rate mortgage (FRM) and adjustable-rate mortgage (ARM) (also known as a floating rate or variable rate mortgage). In many countries (such as the United States), floating rate mortgages are the norm and will simply be referred to as mortgages. Combinations of fixed and floating rate are also common, whereby a mortgage loan will have a fixed rate for some period, and vary after the end of that period.

• In a fixed rate mortgage, the interest rate, and hence periodic payment, remains fixed for the life (or term) of the loan. Therefore the payment is fixed, although ancillary costs (such as property taxes and insurance) can and do change. For a fixed rate mortgage, payments for principal and interest should not change over the life of the loan,
• In an adjustable rate mortgage, the interest rate is generally fixed for a period of time, after which it will periodically (for example, annually or monthly) adjust up or down to some market index. Adjustable rates transfer part of the interest rate risk from the lender to the borrower, and thus are widely used where fixed rate funding is difficult to obtain or prohibitively expensive. Since the risk is transferred to the borrower, the initial interest rate may be from 0.5% to 2% lower than the average 30-year fixed rate; the size of the price differential will be related to debt market conditions, including the yield curve.

The charge to the borrower depends upon the credit risk in addition to the interest rate risk. The mortgage origination and underwriting process involves checking credit scores, debt-to-income, downpayments, and assets. Jumbo mortgages and subprime lending are not supported by government guarantees and face higher interest rates. Other innovations described below can affect the rates as well.

[edit]Mortgage underwriting

[edit]Loan to value and downpayments

Upon making a mortgage loan for the purchase of a property, lenders usually require that the borrower make a downpayment; that is, contribute a portion of the cost of the property. This downpayment may be expressed as a portion of the value of the property (see below for a definition of this term). The loan to value ratio (or LTV) is the size of the loan against the value of the property. Therefore, a mortgage loan in which the purchaser has made a downpayment of 20% has a loan to value ratio of 80%. For loans made against properties that the borrower already owns, the loan to value ratio will be imputed against the estimated value of the property.

The loan to value ratio is considered an important indicator of the riskiness of a mortgage loan: the higher the LTV, the higher the risk that the value of the property (in case of foreclosure) will be insufficient to cover the remaining principal of the loan.

[edit]Value: appraised, estimated, and actual

Since the value of the property is an important factor in understanding the risk of the loan, determining the value is a key factor in mortgage lending. The value may be determined in various ways, but the most common are:

1. Actual or transaction value: this is usually taken to be the purchase price of the property. If the property is not being purchased at the time of borrowing, this information may not be available.
2. Appraised or surveyed value: in most jurisdictions, some form of appraisal of the value by a licensed professional is common. There is often a requirement for the lender to obtain an official appraisal.
3. Estimated value: lenders or other parties may use their own internal estimates, particularly in jurisdictions where no official appraisal procedure exists, but also in some other circumstances.

[edit]Payment and debt ratios

In most countries, a number of more or less standard measures of creditworthiness may be used. Common measures include payment to income (mortgage payments as a percentage of gross or net income); debt to income (all debt payments, including mortgage payments, as a percentage of income); and various net worth measures. In many countries, credit scoresare used in lieu of or to supplement these measures. There will also be requirements for documentation of the creditworthiness, such as income tax returns, pay stubs, etc; the specifics will vary from location to location.

Some lenders may also require a potential borrower have one or more months of "reserve assets" available. In other words, the borrower may be required to show the availability of enough assets to pay for the housing costs (including mortgage, taxes, etc.) for a period of time in the event of the job loss or other loss of income.

Many countries have lower requirements for certain borrowers, or "no-doc" / "low-doc" lending standards that may be acceptable in certain circumstances.

[edit]Standard or conforming mortgages

Many countries have a notion of standard or conforming mortgages that define a perceived acceptable level of risk, which may be formal or informal, and may be reinforced by laws, government intervention, or market practice. For example, a standard mortgage may be considered to be one with no more than 70-80% LTV and no more than one-third of gross income going to mortgage debt.

A standard or conforming mortgage is a key concept as it often defines whether or not the mortgage can be easily sold or securitized, or, if non-standard, may affect the price at which it may be sold. In the United States, a conforming mortgage is one which meets the established rules and procedures of the two major government-sponsored entities in the housing finance market (including some legal requirements). In contrast, lenders who decide to make nonconforming loans are exercising a higher risk tolerance and do so knowing that they face more challenge in reselling the loan. Many countries have similar concepts or agencies that define what are "standard" mortgages. Regulated lenders (such as banks) may be subject to limits or higher risk weightings for non-standard mortgages. For example, banks and mortgage brokerages in Canada face restrictions on lending more than 80% of the property value; beyond this level, mortgage insurance is generally required.^[5]

[edit]Foreign currency mortgage

In some countries with currencies that tend to depreciate, foreign currency mortgages are common, enabling lenders to lend in a stable foreign currency, whilst the borrower takes on thecurrency risk that the currency will depreciate and they will therefore need to convert higher amounts of the domestic currency to repay the loan.

[edit]Repaying the mortgage

In addition to the two standard means of setting the cost of a mortgage loan (fixed at a set interest rate for the term, or variable relative to market interest rates), there are variations inhow that cost is paid, and how the loan itself is repaid. Repayment depends on locality, tax laws and prevailing culture. There are also various mortgage repayment structures to suit different types of borrower.

[edit]Capital and interest

The most common way to repay a secured mortgage loan is to make regular payments of the capital (also called the principal) and interest over a set term.^[6] This is commonly referred to as (self) amortization in the U.S. and as a repayment mortgage in the UK. A mortgage is a form of annuity (from the perspective of the lender), and the calculation of the periodic payments is based on the time value of money formulas. Certain details may be specific to different locations: interest may be calculated on the basis of a 360-day year, for example; interest may be compounded daily, yearly, or semi-annually; prepayment penalties may apply; and other factors. There may be legal restrictions on certain matters, and consumer protection laws may specify or prohibit certain practices.

Depending on the size of the loan and the prevailing practice in the country the term may be short (10 years) or long (50 years plus). In the UK and U.S., 25 to 30 years is the usual maximum term (although shorter periods, such as 15-year mortgage loans, are common). Mortgage payments, which are typically made monthly, contain a capital (repayment of the principal) and an interest element. The amount of capital included in each payment varies throughout the term of the mortgage. In the early years the repayments are largely interest and a small part capital. Towards the end of the mortgage the payments are mostly capital and a smaller portion interest. In this way the payment amount determined at outset is calculated to ensure the loan is repaid at a specified date in the future. This gives borrowers assurance that by maintaining repayment the loan will be cleared at a specified date, if the interest rate does not change. Some lenders and 3rd parties offer a Bi-weekly mortgage payment program designed to accelerate the payoff of the loan.

[edit]Interest only

The main alternative to a capital and interest mortgage is an interest-only mortgage, where the capital is not repaid throughout the term. This type of mortgage is common in the UK, especially when associated with a regular investment plan. With this arrangement regular contributions are made to a separate investment plan designed to build up a lump sum to repay the mortgage at maturity. This type of arrangement is called an investment-backed mortgage or is often related to the type of plan used: endowment mortgage if an endowment policy is used, similarly a Personal Equity Plan (PEP) mortgage, Individual Savings Account (ISA) mortgage or pension mortgage. Historically, investment-backed mortgages offered various tax advantages over repayment mortgages, although this is no longer the case in the UK. Investment-backed mortgages are seen as higher risk as they are dependent on the investment making sufficient return to clear the debt.

Until recently it was not uncommon for interest only mortgages to be arranged without a repayment vehicle, with the borrower gambling that the property market will rise sufficiently for the loan to be repaid by trading down at retirement (or when rent on the property and inflation combine to surpass the interest rate).

[edit]No capital or interest

For older borrowers (typically in retirement), it may be possible to arrange a mortgage where neither the capital nor interest is repaid. The interest is rolled up with the capital, increasing the debt each year.

These arrangements are variously called reverse mortgages, lifetime mortgages or equity release mortgages (referring to home equity), depending on the country. The loans are typically not repaid until the borrowers die, hence the age restriction. For further details, see equity release.

[edit]Interest and partial capital

In the U.S. a partial amortization or balloon loan is one where the amount of monthly payments due are calculated (amortized) over a certain term, but the outstanding capital balance is due at some point short of that term. In the UK, a part repayment mortgage is quite common, especially where the original mortgage was investment-backed and on moving house further borrowing is arranged on a capital and interest (repayment) basis.

[edit]Variations

Graduated payment mortgage loan have increasing costs over time and are geared to young borrowers who expect wage increases over time. Balloon payment mortgages have only partial amortization, meaning that amount of monthly payments due are calculated (amortized) over a certain term, but the outstanding principal balance is due at some point short of that term, and at the end of the term a balloon payment is due. When interest rates are high relative to the rate on an existing seller's loan, the buyer can consider assuming the seller's mortgage.^[7] A wraparound mortgage is a form of seller financing that can make it easier for a seller to sell a property. A biweekly mortgage has payments made every two weeks instead of monthly.

Budget loans include taxes and insurance in the mortgage payment;^[8] package loans add the costs of furnishings and other personal property to the mortgage. Buydown mortgages allow the seller or lender to pay something similar to mortgage points to reduce interest rate and encourage buyers.^[9] Homeowners can also take out equity loans in which they receive cash for a mortgage debt on their house. Shared appreciation mortgages are a form of equity release. In the US, foreign nationals due to their unique situation face Foreign National mortgage conditions.

Flexible mortgages allow for more freedom by the borrower to skip payments or prepay. Offset mortgages allow deposits to be counted against the mortgage loan. in the UK there is also the endowment mortgage where the borrowers pay interest while the principal is paid with a life insurance policy.

Commercial mortgages typically have different interest rates, risks, and contracts than personal loans. Participation mortgages allow multiple investors to share in a loan. Builders may take out blanket loans which cover several properties at once. Bridge loans may be used as temporary financing pending a longer-term loan. Hard money loans provide financing in exchange for the mortgaging of real estate collateral.

[edit]Foreclosure and non-recourse lending

In most jurisdictions, a lender may foreclose the mortgaged property if certain conditions - principally, non-payment of the mortgage loan - occur. Subject to local legal requirements, the property may then be sold. Any amounts received from the sale (net of costs) are applied to the original debt. In some jurisdictions, mortgage loans are non-recourse loans: if the funds recouped from sale of the mortgaged property are insufficient to cover the outstanding debt, the lender may not have recourse to the borrower after foreclosure. In other jurisdictions, the borrower remains responsible for any remaining debt.

In virtually all jurisdictions, specific procedures for foreclosure and sale of the mortgaged property apply, and may be tightly regulated by the relevant government. There are strict or judicial foreclosures and non-judicial foreclosures, also known as power of sale foreclosures. In some jurisdictions, foreclosure and sale can occur quite rapidly, while in others, foreclosure may take many months or even years. In many countries, the ability of lenders to foreclose is extremely limited, and mortgage market development has been notably slower.
