There is a huge glut of pianos on the market as people downsize or die, so the price of used pianos has severely crashed. They typically go for free to whoever will come and take them away, not an easy task. Frankly uprights are harder to move than grands. For a grand you just remove the legs and tip it onto a dolly, uprights are more dense and have fewer handholds. Churches and other charitable organizations have stopped accepting them, and even have seminars to break the news to well meaning donors, so great is the problem.
Grands are similarly devalued and may need hundreds of dollars of repairs to make them playable.
So, bottom line, unless they are a particularly valuable quality instrument, or of sentimental value, they are rarely worth restoring, or moving. My mother's was a pre-depression Weber that was comparable to a Steinway in 1923, which is almost qualified as an antique by NY State. This is important because it has actual elephant ivory keys, and cannot any longer be moved by NY movers till its 100th birthday!
Tuning and regulating a piano are different operations. Tuning is pretty obvious, though there are many fine points to it, but regulation is adjusting all 88 keys to be equally responsive to touch, weight of pressure to striking, and similar in tone. NYS is a new kind of piano regulation!
Good piano techs are also getting harder to find, and more expensive.
Probably more than you wanted to know, but as long as I have studied it, Im glad to overshare!]
Never believed in the concept of TMI!
