How much will my house value increase with the addition of a 3/4 bathroom?We have a half finished basement with a family room and third bedroom and plan to finish off more basement by adding a 3/4 bathroom down there. We have an estimate of $11,000 and one for $18,000 which is quite a difference. Will we get to add square footage of living space to the house after the bathroom is complete or does unfinished basement already count toward the houses square footage? And, how much can we expect the value of the house to increase? We are hoping to sell in the next two years.January 11 - Locust Grove0YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
