One would think we all could just get this number right. What with all the hours of continuing education and certifications. My husband has been working in the Land Surveying business for the past 11 years and the truth is the numbers don't always come out exact everytime when you have several different people running the gun or rather measuring the premis.
In the real estate sales person training class my instructor took great pains to desribe every imaginable way to calculate a houses living space. And trust me there are several ways. Theres the measure wall to wall in each room method. The measure the outside foundation and subtract wall thicknesses method. The laser tool method. The [we'll go with public record] method. The architectural drawings...if you have them...method. And the always popular shrug when a buyer asks does that number include the basement.
My personal favorite is the tape measure wall to wall method of each room. This is a realistic number someone can use to be certain they and their furniture will fit.
This is a great question. Would you mind if I use it in one of my weekly Real Estate Column submissions for The Gardner News?
The standard way an appraiser measures your home is by the foundation size. Personally, I wouldn't lose to much sleep over such a slight difference. If you were selling a 900 sq foot condo in the South End that was in fact 700 sq ft and the $/sq ft was something like $1,000 bucks then you might have an issue on your hands. Best of luck this spring.
As previously stated the answer is "no". When I list, I use the Town documentation. If you do that, you and the agent can state the source and not misrepresent. Prospective buyers will be attracted to the porperty by the general size stated. Once they are in the property, the exact dimensions shouldn't matter so much.
The SHORT answer to your question is "NO", there is no standard way to measure the square footage of a home. If and when your home is listed in the Multiple Listing Service, there is a section regarding Living Area. In this spot, the listing agent will be required to note the "source" of the living area ("Appraiser", "Measured", "Other", "Owner" or "Public Record").
An appraiser will not count living area (finished or not) in the basement or attic, whereas the town assessor (Public Record) might count these areas. It is all objective. This is why your listing agent will most likely disclose in your listing that "Living area is approximate and should be confirmed by the prospective buyer:")
I hope this gives you SOME clarification!
There are several ways to measure a home. An architect measures teh size of a home by living area that is heated. Each town measures square footage differently.
For instance: total square footage for tax purposes include decks, porches, basements (finished & unfinished) but, usually not attics unless they have been finished.
For building purposes, some towns measure total gross area footage, which does not include decks, basements, or under-house garages. It includes, anything with a roof...garages, porches, covered stoops, etc.
Check with the appraiser and ask what the criteria was. It could have been based on only the heated areas.
Whatever square footage you use, just be sure to state in the lising, where you got the size...public records, appraiser, owner, etc.
FYI-architectural measures are not made from interior walls, they are made based on exterior walls.
Good luck with the sale of your home. JessicaHarvey
Do you have your closing documents with your appraisal?
What does tax rolls state?
I am a fairly new agent (working since April 2009) and have asked this question myself.
The answers I received were no.
I don't get why, but that is why a lot of agents are nervous about putting square footage on the MLS, because there apparently is no standard.
