If you realize anyone can find this information, would it influence your "pricing"? Are you undermining your possibility of selling your home because what you think it is worth it more important than what the bank, buyer, lenders, and tax office all agree is the "Fair Market Value"? Surprisingly, many Sellers do.
As a Buyers Agent, we see overpriced homes on a regular basis. A quick look into what comparable homes have sold for will help us in working with our buyers to determine if the asking price is fair. If it is not, we simply move on.
There is a big difference between a home, and a mobile home. Mobile homes lose value as they age much like a car. The useful life is thrity-five (35) years. Compared to a frame home which has a useful life of fifty (50) years. In the end--if the buyer is financing an appraisal will make or break the sale. If the buyer is paying cash, they have also done their homework. Value is subjective, but also transparent.
