It is impossible to predict the future of home prices. In Austin however there is a shortage of homes right now. I see no reason to think the home values will drop.

I'd be happy to assist you too. As you agent I work for you but the seller pays my fees. Free is a pretty good price for professional guidance. The "sales associate" or "sellers agent" works in the interest of the seller NOT YOU. Their job is to get the seller the most money out of you as they can, that's all. No matter how nice they are and how big they smile at you.... more
