Justine,
I would never measure and report the sq ft myself. Either get the owner to give the sq ft, use the tax record, or get an appraiser to measure it. If you make a mistake and represent that the property is a given sq ft and it's wrong, and the buyer sues, you are in trouble. Anytime that I help someone measure, I always take the dumb end and make them do the math.
Here is a snippet from the article I read.
[quote]A recent Texas court decision held a listing broker liable for providing inaccurate square footage information for a listing. The decision has renewed concerns about disclosing the number
of square feet in a property.
The facts of this case are of particular concern because: (a) the
listing agent used square footage from the local appraisal district, which turned out to be inaccurate; and (b) the buyer signed a waiver of reliance upon the square footage information stating that they had not relied upon the information provided.[/quote]
From Hancock and McGill attorneys.
Of course this is in Texas, but I'd avoid stating the sq ft myself no matter what.
