How do I decide which mortgage lender to use (interest rate) - not closing on the house for two more months? - cu members mortgage

I have to look at an exclusive option on a house before. The owners are building a house and not move around and September 1-15, it can be concluded in the house until that time. I'm only 2-3 days left before the house on the market. I need to find a lender and start the hiring process quickly. So far I have with my mortgage company, credit union (not home-CU Members Mortgage). I have a good faith estimate of the 5th June with an interest rate of 6.38. Interest rates rise, and more! I do not know if they still so much that when I finished, I can not afford to get the house payments.I not whether I, the additional costs they charge to freeze pay rates. I also talk with some other lenders to compare, but it's like comparing apples and oranges to me. I'm from the fact that you have an opinion and the other not, but it shares the source .. stunned and so on. No one is willing to negotiate.
