It is impossible not to increase your bottom line with thousands of "Baby Boomers" going into retirement in communities nationwide who will be needing service enriched housing but,  still wanting to avoid institutional settings.Converting some houses into home like personal care can be tricky.   

It's certainly much harder now to cash flow while house hacking with high mortgage rates, but not impossible.

, I'm just having a hard (read: impossible) time finding a job that will accommodate me due to disability. 

A thing to note would be, it may be difficult or impossible to get a qualifying mortgage if there are significant repairs that need to be made such as completely new flooring.

tons of people live off rental income, but here's the thing, as you suspect:- it's REALLY HARD (not impossible) to achieve this in just a few years, unless your cost of living is like next to nothing.- consider investing out of state if your local market is not cashflow-strong.- set your 'living off rental income' financial goal to ~2x what you actually spend every month, just in case. i wouldn't let go of my other income streams until that point, but that's a personal comfort level.- if you CAN live off other active income, you can keep reinvesting your rental income and build wealth faster. david green preaches this on the podcast a lot: find a job you aren't trying to get away from.

I gave up because I need 2 rooms and it was impossible to find two rooms even close to each other. 

I'd look at at least 3-4 family lots at a minimum for economies of scale. the price of land in miami is so high it makes single family home building nearly impossible. flips aren't worth it.

i.e. impossible to get anyone to help, completely disorganized, next to impossible to get someone on the phone, etc. 

You're basically asking for an unsecured line of credit, which you'd only get if you have an established business with a strong balance sheet in the US (and you already do business with the lender).Add 1 and 2 and it sounds like mission impossible to me.

@Richard Edgar doing a cash out loan on land is EXTREMELY hard...I might even say impossible...but I can't speak for every lender in the country on this though.
