How long ago did you buy it?The official (bank) appraisal of my house when I bought it valued it at $180,000.
I haven't a clue how they came to that number, I could list the house for sale at that price today (after doing 50K in work to it) and wouldn't even come close.
Refinanced last year and the new bank required an appraisal (2.25% on a 10yr mortgage, don't care about a $350 appraisal/inspection) and they valued me at $120k, much more appropriate, but also less than I have in the house now.
They're worthless.
After the "crash" they changed the rules for how they appraise houses. Typical .gov knee jerk type changes.
