Definition of Mortgage pass-through security

Mortgage pass-through security

Also called a passthrough, a security created when one or more mortgage
holders form a collection (pool) of mortgages sells shares or participation certificates in the pool. The cash
flow from the collateral pool is "passed through" to the security holder as monthly payments of principal,
interest, and prepayments. This is the predominant type of MBS traded in the secondary market.

Agency pass-throughs

guaranteed by government agencies, such as the Government National mortgage Association ("Ginnie Mae"), Federal Home Loan mortgage Corporation ("Freddie Mac") and Federal National mortgage Association ("Fannie Mae").

Collateralized mortgage obligation (CMO)

are initially lower than those on a comparable level-rate mortgage. The payments are gradually increased over
a predetermined period (usually 3,5, or 7 years) and then are fixed at a level-pay schedule which will be

Insured Mortgage

An insured mortgage protects only the mortgage lender in case you do not make your mortgage payments. This coverage is provided by CMHC [Canada mortgage and Housing Corporation] and is required if a person has a high-ratio mortgage. [A mortgage is high-ratio if the amount borrowed is more than 75% of the purchase price or appraised value, whichever is less.]

Mortgage Insurance

Commonly sold in the form of reducing term life insurance by lending institutions, this is life insurance with a death benefit reducing to zero over a specific period of time, usually 20 to 25 years. In most instances, the cost of coverage remains level, while the death benefit continues to decline. Re-stated, the cost of this kind of insurance is actually increasing since less death benefit is paid as the outstanding mortgage balance decreases while the cost remains the same. Lending institutions are the most popular sources for this kind of coverage because it is usually sold during the purchase of a new mortgage. The untrained institution mortgage sales person often gives the impression that this is the only place mortgage insurance can be purchased but it is more efficiently purchased at a lower cost and with more flexibility, directly from traditional life insurance companies. No matter where it is purchased, the reducing term insurance death benefit reduces over a set period of years. Most consumers are up-sizing their residences, not down-sizing, so it is likely that more coverage is required as years pass, rather than less coverage.
The cost of mortgage lender's insurance group coverage is based on a blended non-smoker/smoker rate, not having any advantage to either male or female. mortgage lender's group insurance certificate specifies that it [the lender] is the sole beneficiary entitled to receive the death benefit. mortgage lender's group insurance is not portable and is not guaranteed. Generally speaking, your coverage is void if you do not occupy the house for a period of time, rent the home, fall into arrears on the mortgage, and there are a few others which vary by institution. If, for example, you sell your home and buy another, your current mortgage insurance coverage ends and you will have to qualify for new coverage when you purchase your next home. Maybe you won't be able to qualify. Not being guaranteed means that it is possible for the lending institution's group insurance carrier to cancel all policy holder's coverages if they are experiencing too many death benefit claims.
mortgage insurance purchased from a life insurance company, is priced, based on gender, smoking status, health and lifestyle of the purchaser. Once obtained, it is a unilateral contract in your favour, which cannot be cancelled by the insurance company unless you say so or unless you stop paying for it. It pays upon the death of the life insured to any "named beneficiary" you choose, tax free. If, instead of reducing term life insurance, you have purchased enough level or increasing life insurance coverage based on your projection of future need, you can buy as many new homes in the future as you want and you won't have to worry about coverage you might loose by renewing or increasing your mortgage.
It is worth mentioning mortgage creditor protection insurance since it is many times mistakenly referred to simply as mortgage insurance. If a home buyer has a limited amount of down payment towards a substantial home purchase price, he/she may qualify for a high ratio mortgage on a home purchase if a lump sum fee is paid for mortgage creditor protection insurance. The only Canadian mortgage lenders currently known to offer this option through the distribution system of banks and trust companies, are General Electric Capital [GE Capital] and Central mortgage and Housing Corporation [CMHC]. The lump sum fee is mandatory when the mortgage is more than 75% of the value of the property being purchased. The lump sum fee is usually added onto the mortgage. It's important to realize that the only beneficiary of this type of coverage is the morgage lender, which is the bank or trust company through which the buyer arranged their mortgage. If the buyer for some reason defaults on this kind of high ratio mortgage and the value of the property has dropped since being purchased, the mortgage creditor protection insurance makes certain that the bank or trust company gets paid. However, this is not the end of the story, because whatever the difference is, between the disposition value of the property and whatever sum of unpaid mortgage money is outstanding to either GE Capital or CMHC will be the subject of collection procedures against the defaulting home buyer. Therefore, one should conclude that this kind of insurance offers protection only to the bank or trust company and absolutely no protection to the home buyer.
