You probably qualify for an FHA Home Loan which is 3.5% Down Payment. It works off the sales price of the home, so it depends on what house you pick. There are also Down Payment Assistance Programs out there, you can view a couple at: http://www.tdhca.state.tx.us/homeownership/fthb/buyer_intro.htm
Not every mortgage company is approved to do each Bond Program, so if you want to use a bond, you need to work with their approved lenders. Also, most bond programs have requirements about repayment policies and about how long you have to live in the home as your primary residence.
There are also 100% Financing/No Money Down Loan Programs if you purchase in rural areas. That is basically anywhere that is not in the City of El Paso or City of Socorro.
All of these programs are subject to qualifing for the loan with the mortgage company reviewing your income, debts, credit score, and credit history.
If you need help figuring it all out, please let me know. I'll be glad to help. Angela
