Appraisal Districts
The local Appraisal Districts are the best source of property Information. They display the owner of the property, local address, legal description, lot size, house size and any other improvements with respective values and more.
The key numbers for residential property are the house square footage (the interior heated area) and the lot size. Note: some listings include other improvements, which can be a bonus. Since much of life happens in the interior heated area of the house, the price per square foot is the most relevant determinant of value. The land is often considered an afterthought - similar to condos with very little land. However, in the long run, the land holds the real value.
