Expand the basement? Sure! Get a bunch of dogs? Why not! Commit to getting to know the neighbors? Sounds great. All while not having to worry about a landlord doing whatever they want at the end of a lease.
It's a very rewarding thing. Is it for everyone? Absolutely not, much in the same way having kids or getting married isn't for everyone either. But for me, there is a lot of value in the actual ownership.
