Monetary sponsorship to modify sellers home to be wheelchair accessible?

Failure time after time to locate agency, grant, corporation, individual to assist in the thousands of $ to modify any home for us. My permanently wheelchair dependent fiance and I can not finance the modifications as well as the mortgage. My credit is excellent, but our incomes are borderline poverty in Collin County Texas, due to the demographics and the influx of wealthier investors from California & New York. We qualify for $120k, and modifications to a bathroom can run over $10k. Lenders do not want to fool with us because they make no money on helping us qualify for special fundings. There is a home built 1960 that met 99% of our needs, but a developer purchased it & the land to build $$ homes, and they will trash it afterwords. I don't know how to approach them; would it be possible they could "give" us the old home? Then, all we'd have to do is find funding to move it? And the land? I have some property in mind, but I'd need to double my savings as a down payment. :(

Maybe you can contact Habitat for Humanity. They assist folks who don't quite have enough money to qualify for a traditional mortgage.

I don't know if they do partial projects, but they might.

Have you talked to someone at your church? Perhaps someone in the congregation or a group may be willing to help.
