In our opinion the best source of free information is found by asking a Real Estate Agent in your area who does free Appraisals. Of course they would like you to list your house with them but they usually have a whole raft of paid sources of information. In other words, you can use their paid sources and their local knowledge to get a really good idea of how much your house is worth for FREE.
Who knows…. you may want to sell you house with them after all.
