It seems like USAA is pretty risk adverse when it comes to their mortgage lending. When i was looking to buy a place near DC, they were only going to approve me for 100 something thousand because they perfer your debt to income ratio to be around 28-30% or something low like that (Navy Fed is the same way, but their closing costs seemed to be a good bit higher). I ended up using the financing people of the builder and they were willing to take a debt to income ratio of 54% (I had no other debt but what the mortgage was going to be) and gave me a loan for $304,000. I ended up with my main mortgage through wells fargo after they bought it, and I have no problems dealing with them.
