A good faith estimate is pretty much what you’d get from a realtor! We were about to go into contract on a house years ago when our bank called to tell us that the selling price could not be justified by the comps… so that they wouldn’t lend us what we needed to purchase the property.
The realtor cursed the bank… the sellers cursed the realtor…we were just grateful to be spared buying the most expensive house in the neighborhood based on the realtors “food faith” estimate!
