I couldn't care less about the credit score of your friends, I'm trying to explain to you that you can't categorically say that you can't afford a home with a $150k without knowing all the facts.... Are you seriously asking me credit score of my colleagues and friends?
Nah, 150K won't help you when you don't have downpayment large enough.
People come to this forum for guidance, and you are not doing them any favours by saying things that can easily be refuted by people who are already here.
