You're not getting normal homeowners insurance, which you might have calculated for 250.yes the roof is not your responsibility, but repairing the fridge or having the disposal replaced is totally on you. replacing appliances is also on you when they finally die. lights, faucets, toilets, flooring, ceiling fans all have a finite lifespan.

Water is pumped from the lake to the toilet that's located in an outhouse.I am wondering where do I find financing to buy-out the other party?

I also plan to hire them even to do stuff that requires a license such as installing fans and toilets because they give me a better price.

If your good at it, you can make some dope cash without any broken toilets or BS.

I don't even get that part, but also...How could someone hurt themselves installing a toilet?

That along with the cost of electric, plumbing, finishes etc... the additional $350-$500/mo you could earn off of it doesn't pan out.A better move owuld be to finish off the attic as an additional bedroom for your upstairs unit.

they should be able to flush toilet, brush their teeth. showering maybe a problem.  

A "deal" in an "up and coming" neighborhood may be a total dump in a bombed out section of the city that shows little hope of panning out.

(I bent plug prongs inwardly slightly to solve problem.)The water stopped going down the toilet. 

It sounds good to me since boxes, old exercise bikes, etc. dont call to complain about running toilets.
