Look for a credit union or small community bank that will offer a second mortgage. They will typically lend 15% of the required 20%. 5% will come from you. However, if the second mortgage company is willing, you can get the first mortgage at the conforming rate of $417,000 then the second for the remainder up to 5% from you. Rates on seconds run around 9.5% for 30 year fixed and 9% for 15 year fixed. You'll also have to make sure that the first mortgage company will accept the second mortgage company. We call that a CLTV (combined loan to value). Your LTV is 70%. Your combined LTV or CLTV is 95%. This will also keep you from having to pay mortgage insurance (MI). The MI on FHA is .55% of the loan amount plus you will have to pay a 1.75% funding fee (which is financed into the loan). It may take a little leg work, but may be worth looking around.
