So if I offer 10% more than asking (because I am changing jobs and need a house NOW) and 3 other people offer asking, the house is worth 10% over ask. So the 3 who offered, the seller, and the Realtor were all wrong and only I at 10% over is correct? You are making the point that there should be no appraisals and lenders should give you 80-95% of what ever you offered to pay. That seems like a mess waiting to happen.
I can ding a buddy who offers me 50% over true value, defaults on it and I can step in a year later and repurchase it for 2/3rds of what is owed possibly. Easy to game that system.
BTW, what did the other appraisers say your house were worth when you filed the complaint?
