I plan on a 25′ Catalina sailboat with two heads and two cabins with galley. That puts me at under $400 for slip fee. So factor a $3K mortgage plus $500 slip fee not too bad for best of both worlds.
Actually since I am also a pilot, I’ve looked at buying a home outside of California in place like Nevada, Arizona or Oregon where prices are even cheaper!
So a plane at 80K plus sailboat at 10K plus home in OR/NV/AZ at $200-300K that makes a monthly nut of 3-4K to have all toys accounted for and tax breaks for business. Or live in cheaper part of California like Chico or Oregon coast.
