The FHA is insuring a greater percentage of loans than during any time in recent history. In 2006, it insured roughly 5 percent of the purchase mortgage market. Today, it insures one-quarter. ”Going FHA” is more common than ever before — but is it better?

The answer — like most things in mortgage — depends on your circumstance.

Like its conforming counterpart, an FHA-insured mortgage is available as a fixed-rate loan and as an adjustable-rate one. Payments are made monthly and come without prepayment penalties.

That’s where the similarities end, however, and decision-making begins. For homeowners and buyers across San Jose , FHA mortgages carry a different set rules as compared to conforming loans through Fannie Mae or Freddie Mac that can render them more — or less — attractive for financing.

For example:

• FHA mortgages can be assumed by a subsequent buyer. Conforming loans may not.
• FHA mortgages require mortgage insurance, regardless of downpayment. Conforming loans do not.
• FHA mortgages do not have loan-level pricing adjustment. Conforming loans do.

FHA mortgages also require smaller downpayment requirements versus a comparable conforming mortgage. FHA calls for a minimum downpayment of 3.5%. Conforming mortgages often require 5 percent or more.

And, lastly, FHA mortgages are priced differently from conforming ones. Since 2005, the average FHA mortgage rate has been below the average conforming mortgage rate more than 50% of the time, meaning that an FHA mortgage’s principal + interest payment is lower than a comparable Fannie/Freddie loan.

Today, conforming mortgage rates are lower.

So, which is better — FHA loans or conforming ones? Like most things in mortgage, it depends. FHA-insured loans can be big money-savers or money-wasters. To find out which is best for you, ask your loan officer for today’s market interest rates and study the results.

With less than 20% equity, the answer is often clear.

After this week ends, the FHA is raising mortgage insurance premiums on its new Palo Alto borrowers. It’s the FHA’s third such increase in the last 12 months.

Beginning with FHA Case Numbers assigned April 18, 2011, mortgage insurance premiums will be higher by 25 basis points per year, or 0.25%.

Against a $200,000 loan size, the MIP increase adds $500 to an FHA-insured borrower’s annual cost of homeownership. All new FHA loans are subject to the increase — purchases and refinances.

Existing FHA-insured homeowners across California are unaffected. Premiums do not rise for loans already made.

The FHA is increasing its mortgage insurance rates because, as a group, the FHA is insuring a much larger percentage of the U.S. housing market.

In 2006, the FHA held a 4 percent market share. By 2010, that share ballooned to 19 percent and, today, it’s estimated to be even higher.

In its official statement, the FHA says that the quarter-point MIP bump will “significantly strengthen” its reserves which are depleted because of delinquencies and defaults. By law, the FHA’s capital reserves must meet certain levels.

Therefore, to meet these requirements, the FHA is rolling out its new mortgage insurance premium schedule:

• 15-year loan term, loan-to-value > 90% : 0.50% MIP per year
• 15-year loan term, loan-to-value <= 90% : 0.25% MIP per year
• 30-year loan term, loan-to-value > 95% : 1.15% MIP per year
• 30-year loan term, loan-to-value <= 95% : 1.10% MIP per year

In order to calculate what your FHA monthly mortgage insurance premium would be, multiply your beginning loan size by your insurance premium in the chart above, then divide by 12.

The FHA also charges a 1 percent, up-front mortgage insurance premium at closing. That figure remains unchanged.
