I found a home I like. The seller(also a realtor) bought last year for 87K did some improvments and now wants to sell for 179,900. How do I know what to counter? What should I pay for as far as closing costs as the buyer. I will make an offer of $163 since roof is 15 yrs old. Want to make offer since my realtor says she has a client that wants to see the property I want..
