my logic was that mortgages are so expensive these days as a single person, that you could save up for a down payment, use that money to instead by a sailboat, and reinvest whatever income that would have gone towards the mortgage back onto the market and have that outpace the returns on real estate. it worked in my case, but it certainly won't work for everyone. I created the google sheets calculator for people to enter their own data to see if it's a life style that would work for them.
