Adding another bathroom....

[Chad Fernendaz]

I need some help. 

I am thinking about buying a property with 3 beds and 1 bath. 1 bath to me just doesn't seem very attractive to a family. Or maybe I'm wrong? I noticed the area the house is in has a lot of 1 bathroom houses with around 3 bedrooms. Is this going to be an issue? 

I just know if I had a family I would want the kids to have their own bathroom, but is this passable? And if not, how hard would it be to make another bathroom? Maybe I could turn a bedroom into a huge bathroom? Any help is appreciated thanks
