I went so far as to buy a dehumidifier so he could use the basement for storage, replace the screen his dog damaged at no charge and other little things I don’t technically have to do to make it nicer for him  Now I feel like he’s taking advantage.Now the reason I’m considering giving in. 

But if this is the last affordable complex in the area and the price increase to "market rates" causes them to move much farther away and uproot any connections (like daycare and the like) that they have in the area... well, I'm not a fan of that.Moving on to self storage.

The 1970's attic apartment was just wasted storage for 12 years so we rehabbed it for $2500 & our live-in maintenance guy now pays $475/month plus does any & all building & property maintenance.But we do all the work ourselves.

But depending on the years of your HVAC and hot water tank, you won't need that for a while.

I have read that for determining equilibrium a good rule of thumb is to use an avg of somewhere between 7-8 sq ft of self storage per person within the radius you are analyzing.  

Will that tank your business buying tax liens in MD?

Is seller financing a good bet with things about to potentially tank, or should I go with more traditional means (or stop looking for rentals and look more for flips). 

The Shark Tank is wrong all the time.

. $50 a month) and the rental market tanks so you start operating a negative cash flow which means you're eating into your ability to save.If you have buy weak, a downturn will affect you.

There is also a large 12x14 storage room that could be converted into a room too (or opened up for a kitchen).
