In response to the Feb. 15 editorial about the Tenant Assistance Program {"The Costly Search for Housing"}, I am a TAP certificate holder who has been in search of adequate housing for myself and my two small children since December 1987. I have an application in for a newly rehabilitated two-bedroom apartment with developers who participate in TAP, but it is pending approval. Aside from that possibility, my search has been an ongoing but fruitless effort even to get my foot in the door. The places that do rent to TAP participants are always full, and the managers are up to their eyeballs in applications for TAP units.

The article noted that "landlords have been unwilling to participate in the plan." Many property owners have an image they like to project in the quality of their tenants. They think low-income tenants are uncivilized and may devalue their property through negligence, destructive kids, drugs and the whole gamut of negativities usually attached to low-income people. Of course, a lot of it is just snobbery: low-income people just don't fit the criteria, especially in the choicer neighborhoods of Washington.

True, TAP can be a godsend to people like me, who simply cannot alone afford the high rent for safe, adequate housing. Yes, low-income people need security too and are capable of maintaining a decent quality of living. But TAP is only as good as the people who are willing to endorse it. LINDA HARRINGTON Washington
