All home value assessment apps should really only be used for a ball-park range and even in some cases that isn't even accurate.
The truth is, how can a computer program truly evaluate your home's worth without looking at all the updates that have been done over the years.
I can tell you that two identical homes in size could easily have a 100K swing in value depending on the condition. I can also tell you a home that has a super steep back-yard will significantly sell for less than one with a flat useable space.
Show-ability also has a tremendous effect on value. The better your house shows, the faster it will sell and for more money.
So if you are ever curious the value of your largest asset, give us a call and within 15 minutes, we can provide you a very accurate assessment.
