Because of the condition and where it’s heading along with other lease violations such as non tenants living there, filth, etc.

My answers are; if you don't believe you can do something then you can't and if you don't have a good business model in writing, or in your head then you are only 'WInging It' and any success will be totally reliant on being lucky. 

Usually it's best to line up a plumber and then head over and try to fix it beforehand!

For instance, if there are a total of three equal balance sheet contributors, your % becomes 2.5% (7.5%/3).

I guess I’m uncertain of what’s going on with the economy and where it’s likely headed and what that means for rent prices.

If you don't close, there's no harm done, and you'll have a head start on filling your rooms when you do. 

I read about some investors who's behind on their mortgages, collect rents in advance, then skip town.I had tenants with legitimate reasons to pay in advance, for instance, a convent was downsizing, renting apartments for member nuns, They need a number of apartments, had the funds, but back in those days, had to process 20 to 30 rent checks a month in their accounts payable department just for rents is too much.

I haven't ever done online stone counters, and the thoughts I run through my head are "how does this slab get dealt with if it shows up with a crack in it?"  

Trying to keep as much cash on hand as possible but I understand your point.The challenge: As prices for homes go up, the rental market in certain areas can hit a ceiling (based on avg I come in that area) so you start heading toward diminishing returns. 

After my first year of doing a couple BRRRRs, I'm trying to wrap my head around the money we pull out via refi.
