This nonprofit organization and moderate-income housing in the District. He also is active in S.A.F.E., Inc., a group of 15 S&L formed two years ago for the same purpose.

While the league has no official position on housing speculators, McConkey said his own institution, Perpetual makes a practice of lending only to home buters who plan to occupy the premises. he has a conservative outlook on the prospects for higher mortgage rates, predicting they will reach "no historical heights" this year.

He expects a fair fight between S&L's and credit unions, which have recently won the right to offer home mortgages. Right now, he observed, credit unions are 'in their heyday" but said he forsees they will come under increasing government regulation as they gain a bigger share of the mortgage market.
