All of the earlier advice is 100% correct. To expand on the FHA route vs. conventional. With your credit score there is a 3.00% adjustment to the price of your loan. Simply the difference between a rate of 5.500% & 6.500%. Even though the FHA loan will have mortgage insurance and a funding fee the overall cost of the FHA loan will be lower. Example:
$150,000 purchase 20% down
Conventional @ 6.50% P&I $758.48 FHA @ 5.50% P&I + MIP = $747.93
Plus in 5 years you can drop the monthly MIP cost and your payment goes down $54.66.
FHA as mentioned before would also eliminate the need to season the gift funds for 60 days.
Have a great weekend!
