You can tell how much your house is worth by finding out what has sold in the area which are comparable to your home. A good professional real estate agent who has your interest at heart is the best person to contact for homes that have sold in your area. Having said that, there is not alot of inventory these past few months. Anything that is priced right, will sell within a day or two. There is a buying frenzy right now, as the interest rates are low and the demand is high. The inventory is limited which can drive you price up a bit above the market value. Also, in Dayton, we are in a rural area and there are programs for first time buyers who have jobs and a good credit score. These are the people, if educated, will be the buyer of your home.
I hope this helps.
