It is especially important if you have 2 or less bathrooms in your home currently. But if you already have 3 1/2 baths, adding another one isn't quite as critical to potential buyers... in my mind.
Thanks, and good luck,
I for one would consider a couple of factors before commiting to a major cellar conversion...and I would consider $5,000 for a bath a big investment.
In my opinion, whether or not there are windows in the basement, and outside access, or a secondary means of egress should always be considered prior to using a basement for anything other than what it was designed.
Hope people find this helpful.
In actual fact, appraisers do not add much to the value of a home with a finished basement. What you should consider is how this will affect your quality of life while you live there. If it makes your life better, then do it.
As for the basement, just be careful. As someone mentioned below, finishing your basement for $30k will probably not add that much to the value of your home, but you dont have to spend that much. You can probably do it yourself for around $7500. Or you can call one of those basement finishing companies. Just don't go crazy if you're doing it to increase your home value.
do what you want in the basement for you and your family. Plan on staying in your home for a while and getting the value out of it for yourselves.
