I turned my mother-in-law apartment (walkout basement) into a music studio complete with piano, drums, bass, computer, amps & speakers. There also a bar and bedroom.
I use my library (third floor) for sax quartets and right now looking around I have six saxes and four clarinets on stands, two music stands, a Thomas organ, and a piano. (It's a mini version of
Jay Easton's office)
People are amazed when they see the setup as there are guitars, pianos and organs on every floor of the house. But I don't buy boats, second houses, vacation property and the like.
That said, I have three to four bands practicing out of the music studio in any given week and a guy who comes Wednesday to do five hours of lessons with some of my sax buddies. He's installed a terabyte of music that he calls up to show his students (including Suzy and me) how this pro plays outside of the changes or that song was played in a swing rather than Latin beat.
Additionally I have file cabinets full of music for quartets, ensembles, and big bands. The book for the WJE has over 200 songs in it. The Dissonance has over 100 charts in their book so far. And the Professor Gadget sax quartet has over 50 charts in their book. Suzy is the librarian and has probably spent 100s of hours labeling and filing things away.
It's been a labor of luv that started five years ago.
