Selecting a good used piano can be tricky. The internet is flooded with many choices including “free piano if you will haul it away.” Unless you are willing to hire a piano technician to inspect the instrument, we would recommend not going this route.
Generally, a free piano is one that someone has been unsuccessful in selling for myriad reasons and hopes that someone else will pay the expenses of moving and costly repairs. Except for a very rare case, most of these instruments were mass-produced and have already lived their life of usefulness. Many times, there can be service issues that are more costly to repair than the value of the piano. Many people have gone through the costly moving process only to find that a mistake was made and that the piano requires hundreds of dollars of work.
