1. I'm considering buying a home from a FSBO--For Sale By Owner. I've done my market research, and the seller obviously has not. He is offering the house at below the market price for a home that size and age. Am I under any obligation to talk to the seller about his low price? Should I be wary that the price isn't what the market might sustain? 


2. If I really want to sell my house for maximum gain, should I put in a pool or what is the best what is the best improvement to get the biggest bang for my buck?
