Let’s say that by cashing out a bit more than you started with and by saving all the cash flow you are able to do one more then for every 4 houses you have (fractions discarded).

That tenant thankfully decided to move on their own after we refused to allow them to start piling stuff in the carport and other common areas; something we could still control;  basically we told them we would start discarding any items left outside and they couldn't handle that.
