Starting Monday, December 13, 2010, Fannie Mae is changing its mortgage lending guidelines.

For some mortgage applicants of NH , the loan approval process will simplify. For others, it will toughen. How you’ll be affected personally will depend on your credit profile and your loan characteristics.

Among the biggest changes from Fannie Mae is a new set of guidelines for gift funds. When the new rules roll out, accepting cash gifts for downpayment will be easier.

Undetr the new guidelines, buyers of owner-occupied, 1-unit properties (i.e. single-family homes, condos, townhomes) can forgo Fannie Mae’s typical, minimum 5% personal downpayment contribution. Downpayments on homes meeting the above criteria can be comprised of 100% gifted and/or granted funds.

Buyers of second homes and multi-unit properties, however, are not exempt.

There’s also two changes pending with respect to revolving debt.

1. Debt with less than 10 payments remaining may no longer be waived in debt-to-income ratio calculations
2. Debt lacking a monthly payment on credit must be assigned a payment equal to 5% of the outstanding balance

Both of the above should increase the number of loan denials in 2011.

And, lastly, Fannie Mae changes some of its documentation requirements, the most noticeable of which will be with respect to income verification. Salaried workers and applicants whose commission/bonus accounts for less than a quarter of their income will have fewer paystubs to produce for underwriting.

Loan applications taken prior to December 13, 2010 are exempt from the new rules.

Conforming mortgages is so named because, literally, they conform to the mortgage guidelines set forth by Fannie Mae and Freddie Mac.

Of the many traits of a conforming mortgage, one is “loan size” and loan sizes have limits. Mortgages exceeding this loan size limit cannot be securitized as a conforming mortgage and, therefore, are ineligible for conforming mortgage rates.

Conforming mortgage rates are often the cheapest source of mortgage money for residents of NH , all things equal.

Each year, the government re-evaluates its maximum allowable loan size based on “typical” housing costs nationwide. Loans in excess of this amount are often called “jumbo”.

Between 1980 and 2006, as home prices increased, so did conforming loan limits — from $93,750 to $417,000.  Since 2006, however, home prices have retreated but the conforming loan limit has not.

In 2011, for the 6th consecutive year, $417,000 will be the country’s conforming mortgage loan limit.

Conforming loan limits very by property type. The complete breakdown is as follows:

• 1-unit properties : $417,000
• 2-unit properties : $533,850
• 3-unit properties : $645,300
• 4-unit properties : $801,950

Despite the limits, some parts of the country get “loan limit exceptions”. In areas considered “high cost”, conforming loan limits range from $417,001 to $729,750. High-cost is defined by the median sales price of a region.

Los Angeles County, for example, is a high-cost region, along with a lot of California. There are less than 200 such areas nationwide, though.

You can verify your local market’s loan limit via the Fannie Mae website. A complete county-by-county list is published online.
