Thanks for posting the toilet pic first.

Also, weird stuff would pop up, like finding that the reason the toilet was clogged was because there was a pair of underwear jammed down in there. 

Then you can actually see what you are working with and get  sense of what it will look like when it's completed.Also, take the house Subject To, (take over the loan) give the seller some equity $$$, and if it needs $80,000 of reno on a $145,000 ARV, tell whoever told you that you want him to redo the estimate without the solid gold toilet.

Go turn off all the water in the unit, including manually shutting off the toilets, etc and watch the meter.

Is any type of composting toilet allowed?

you know i have seen "rich" people squat as well almost using their wealth as a shield.

For 20 years I have managed my own properties so I wanted to offer some thoughts on the advantages of self managing.midnight maintenance calls for self managed are mostly a mythVia a well written lease and open communication with my tenants I let them know that they are responsible for things like plugged toilets, leaks under sinks etc.

is it better to invest in real estate passively with a deal sponsor or DIY and deal with tenants toilets trash in the short run and then go about building your portfolio flip make some money and go about passive investments I need a suggestion please - Sri

Personally, I know how to replace a toilet in my rental units, but I rather pay for it at this point and focus my time on family or building my business/portfolio versus getting lost in the details. 

(There will be things that need replacement after year 1)  Consumable supplies (coffee, toilet paper, soap, trash bags, etc.)
