The developer of the country's only private reverse-mortgage program for elderly homeowners who want to cash in on the value of their homes while they are still in them has no plans to expand the program to include District of Columbia residents.

James Burke, president and founder of American Homestead Mortgage Corp. of New Jersey, said, "We have no present plans to come to D.C., nor do we foresee a time when the market situation there would change sufficiently to make it worth our while."

In late February, American Homestead began offering reverse mortgages to qualified Maryland homeowners 62 and older through Standard Federal Savings & Loan's 21 branches in the state. Since then, about 270 persons have applied for the program, according to Robert B. Schwartz, an officer of Standard Federal in Gaithersburg.

American Homestead's Burke said the bank would not consider the District for the "same reason we decided not to go to Delaware . . . too few people. The economics just do not work for us in D.C. We could not generate the volume of transactions in Washington necessary to make a return on our investment. We are a bank, not the tooth fairy."

Burke said his bank plans to expand the program to Virginia sometime in 1987 after getting licensed and bonded there. "We will definitely go to Virginia. It is our next targeted state and, hopefully, it will be by 1987," Burke said.

The Individual Reverse Mortgage Account program gives elderly homeowners a monthly payment based on their age and the age and value of their home for as long as they continue to live in it. When the home is sold or the resident dies, the principal and the interest -- currently 11.5 percent -- is deducted from sale proceeds.
