Valuation issues after updating room addition and square feetHello.We added on a fully permitted ground floor room that added approx 400 square feets. We have also done a extensive kitchen and land scapeing remodel. I added these into the house profile and the value of the house actuually went down. I see alot of other home owners adding sq feet under a ADDITIONAL SQ FEET heading. I cannot seem to find this in my home descripion. Look at 377 olympian way, 94044. They added 1600 plus square feet (impossible) to this house to unfairly raise its value. I am trying at add 400 + real square feet to my house at 144 hopfield Drive, 95630 and my value actually goes down?September 14 2011 - Folsom00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
