Why is it necessary to survey a home each time it is sold?
Follow on 
A survey is very important. It shows the amount of property purchased, the location of improvements on the lot (such as the house), and the location of the lot itself.
A new survey is needed each time a property is sold not because a house might move, but because of encroachments, easements, and such. For instance, the neighbors put up a fence last year and the fence is actually on the property you want to buy. If the fence remains in place, you have less property and perhaps your parcel is worth less. Or, the current owners built a garage which extends over the property line. Your neighbors will allow it to remain in place, but only if you pay them $27,000 for the use of their land.
