He also cannot do it in the extra 2 weeks that you thought it was going to take.

My place is somewhere in a B class neighbourhood, I’m thinking it’s worth the extra cost to maybe just commit? 

I didn't see "pay an extra $15k in taxes" in the original post so thanks for clarifying.  

Despite the damage, they made up for their mistake and covered the extra costs, so I plan to use them in the future.

A part of me wants to do a rent to own and keep it one single family 4/2 house and have the downstairs tenants go upstairs to cook food, and just rent it out for him for market rent which is about $2,400 and then give him his $1,200 plus some extra and keep the rest.

There is no property that works for my situation that is currently on the market, so I'd be rolling the dice on whether or not the flexibility that comes with the investment loan is potentially worth the extra cost on the loan when there may not be a property that pops up that works for who knows how long.

A simple sign stating video surveillance  is in use as well as leaving written notice about extra fees for dumping large materials should suffice on both fronts.

They don't exist, and you can't make them.Knowing what a bad deal they're locked into, Chinese investors who have successfully acquired extra property then look overseas, and they cash out in China to leave someone else with the hot potato and buy up property in HK (before recent events), Australia, Canada, and some cities in the US without many black people (mainland Chinese investors hate buying in areas with black people). 

Hard to get your exact scenario right without the extra info.
