When I bought my house I looked at the estimated value, or appraisal. When you try and sell it, I assume if its valued at a lesser amount, it would be harder to get an asking price at similar or above your purchase price. If you payed $100,000, then had it re-appraised at $50,000. After a year you try and sell it but you are asking $105,000. As a buyer I am going top say wait a second, it was only appraised at $50,000 a year ago. What did they do to bring the value up $50k?
