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. 

Need to include roof 25 year life span, appliances and hot water heater 12 years, hvac 20 year life span, bath and kitchen remodel 20 year, etc.

The smart home can be monitored remotely with a Nest thermostat, security cameras, doorbell, and home security alarm while the Rachio weather-intelligent irrigation system lowers the water bill.

There was a notice of a termite inspection on the water heater, declaring that no termites were found.
