I didn't read through any of this, but I'm planning on closing my first house at the end of this month. I bought a house in Overland Park and had a real estate agent that I found was very helpful and honest. I'm usually very good at seeing through people that BS, haven't been proven wrong on that too many times. He would openly point out negatives to a house and basically hint that maybe house A or B wasn't really what I was looking for.
You probably know as much as me about house buying even still, but if you have any questions, I'll be more than happy to help, just PM me. BTW, my credit was in the 760s and my rate was 5.875%. I'll also give you the name to my realtor if you'd like.
