I was able to successfully negotiate a new pipes, water heater, front porch, etc.

The damage from fire, smoke and water are pretty significant.  

It's All County NEO, I've had small ticky tack issues with regard to bad or slow communication here and there, as well as what I believe to be not properly crediting the owners portal with water and sewer reimbursements I pay.

We basically had to add an AC and hot water heater, add lighting, rebuild the kitchen, and touch up paint.

It's an old house and recently during a renovation, I realized that both sides waste stacks are sharing a shaft touching one another and the neighbor's one was cracked, practically watering my side with sewer every time they flush their toilet.

For plumbing they generally (it's different in different cities) will pass the rough in inspection first, then you have to do the other stuff (like install the bathtub and fill it with water) and pass that stuff before you do the wall tiles etc.  

I don't think he's ever actually even seen the house, if he did I don't know how he could have missed the Holton-Wise stickers on the doors, windows, cabinets, furnaces, hot water tanks and electrical panels.

Imagine the following scenario:Suppose you bought a SFR at a good price (20% below retail) and made very conservative estimates for water, garbage, vacancy, property management, capex, and repairs. 

Leasing by the room is uncharted waters for me. 

Are one of you flying down the only to find out it’s no big deal his phone was turned off and the rent is in the mail, OR, the house has been gutted and flooded with water for 30 days.
