If the furnace and water heater is gas I would stay with the gas range.

In that case generally depending on the amount you are seeking in damages it could be small claims court or superior court you have to file in.

They’re also incentivized not to damage the property because they do not want to lose their large security deposit.Obviously this would not work for all markets, but it has been a very effective strategy for him.

I was told by a member of the Taunton zoning commision as it is now its a legal small multifamily but the zoning ordinance states that if the property is damaged 65% or more (determined by the building commissioner) through fire, flood, wind ect. then it has to be rebuilt conforming to the current zoning laws, which is single family only for that area.

I did a full tearout of the kitchen ceiling and remediated all the water damage.

Is it a (hot air) furnace or a (steam/hot water) boiler?

I'm not a fan of these "No money down" deals because all it takes is a burst bubble or a market correction and now you're under water on a property.

I have witnessed at least 2 other units with severe water damage because of the plumbing in common areas.

Fixed minor damages on roof, doorframe, and HVAC.
