<p>I read on the College Board website that a conservative but reasonable value is best arrived at by using the Fed. Housing Index Calc. and then add 10% to what is says. I tried it with my house and it came out with a value for my house that would be a great bargain for a buyer if I actually sold it for that price, but not so suspiciously low that it looks like I’m lying. I’m sure it will vary for lots of folks though.</p>
