Sure, it's a good house, but it probably is going to need some work to get it ready to live in. Sometimes, it takes a little, sometimes, it is a lost cause, depending of the quality of the building, the way its weathered its climate, and the way it has been used/abused and cared for.
Same with pianos!
Most of us know we never do everything we are supposed with the house or the piano, primarily because life happens (thank goodness!).
So when you see that free piano or you are inheriting the family piano, before you spend money and resource to move it in and have a technician check it out, why don't you have a technician check it out first to see if what it needs and if it will work for you, then spend some money and resource to move it in your home. church or school!
