My real estate tax statement lists my property being valued at a certain amount. No one fromthe tax assessor's office has been in my housein 20 years. Chances are good that the tax assessor used what is known as a mass appraisal technique toarrive at the value of your property. If you believe that your appraised valueis in error contact the tax assessor and request an adjustment. I measured my house and came up with a smallernumber.
Square footage is measured from outside wall to outside wall.
If you measured from insidewall to inside wall your results will be smaller. For example, let's say that a house is 40 feet by 50 feet and has a wall thickness of six inches. Outside wall to outside wall is 40' times 50',or 2,000 square feet. Inside wall to inside wall would be 39.5' times 49.5', or 1,955 square feet. Square footage is only a method of comparing one property with another.
