Have your friend start eating the disgusting tenants food or just start throwing some of it away saying that it looked like it was going bad.5.

I've read several books, listened to podcasts, eat, breath and speak real estate to anyone who will listen lol.

I'd save the money that I would have spent on housing to accelerate my nest egg for the next building.If househacking isn't an option, then I'd do live-in flips to buildup cash and invest that into rentals (BRRR or buy and hold). 

If not, you may have to eat the cost.

From a plumber it'll cost you $1,500, find a good local guy though and he'll do it for about $700.It doesn't hurt to ask for it, though if it comes down to it, and the deal still makes sense, then I'd say just eat the cost.

is there perhaps another popular car wash closeby eating their lunch?

At least I will be paying for something instead of an empty living space and food that he is not going to be eating.  

@Michelle Dong, I do not live in Indy nor do I know the market but I do have just a little general house hacking advice:  I just jumped into my first house-hack and after looking at several properties over almost a year long search I decided that I am going to just eat a little bit of cash flow in order to live in a little bit nicer (B-) area.

There have also been some comments about how noisy it is all around the condo, as the eating area and living spaces all have laminate flooring (with bad padding), but the noises from daily living operations are bearable (although noisy) for the unit owner below. 

Since the section 8 tenants are not paying much for the rental, they have less incentive to keep the property in great shape and every renovation eats at your cash flow.More Work to Evict Difficult TenantsIn NYC its already a lengthy process to evict a tenant now add a Section 8 eviction in there, that means more work comes into play as you will need to send copies of documentation throughout the eviction process to your local housing authority office or case manager.
