My wife does it, she has a primary job as a National Account Manager for a Chinese company and her old VP owns 4-500 apartment units in like 40 buildings (I never get this number right) so she does his books as a side gig because she doesn't trust anyone else to not rip him off So she takes care of the money side of the rentals and I take care of the upkeep and repairs. Like today I had a dishwasher put in. We are planning on having a minimum of 20 paid off when we retire so we have another stream of retirement income. It really is not that hard unless you work like 60 hour weeks then you have to pay a management company which eats your profits. I love the rentals for the tax write offs.
If SSI is still around that will be just bar money
Swede: My expertise in this area is extensive. The essential difference between a "battleship" and an "aircraft carrier" is that an aircraft carrier requires five direct hits to sink, but it takes only four direct hits to sink a battleship.
