Then, how does an appraiser determine the square footage of a house?
Appraisers tend to use one common measurement type when it comes to measuring the square footage. They measure the Gross Living Area of your home. For condominiums, they generally just measure the interior meaning only the inside area of your unit. Some may add 6 inches to the measurement for the wall thickness.
Likewise, is square footage measured from inside or outside? The measured indoor space (all rooms, closets, hallway, vestibule) equals 1,430 square feet while the house is listed at 1,680 square feet. My agent told me the square foot differential exists because I measured the house from the inside while the standard procedure is to measure from the outside.
Also asked, how do you get the square footage of your house?
Just break out your measuring tape—or a laser measure—to get its length and width. Multiply the width by the length and voila! You have the square footage. Say a room is 20 feet wide by 13 feet long, then 20 x 13 = 260 square feet.
How is living area in a house measured?
Calculate the living area (and other area) by multiplying the length times the width of each rectangular space. Then add your subtotals and round off your figure for total square footage to the nearest square foot. Double-check your calculations. When in doubt, recheck them and, if necessary, re-measure the house.
