I got a call the other morning at 4am from a tenant that was distressed because another tenant had come home drunk at 2am, turned up the stereo and proceeded to pass out in her apt, and none of the tenants could get her to come to the door so they called the police and after an hour of beating on the door they finally woke her up at 4:30.Try a sewer pipe backed up because a tenant flushed feminine products down the toilet and your the one that has to snake the system from in front of the blockage because it's the only way to get to it without draining 200 gallons of sewage on the basement floor, knowing that once you free the blockage you better get the snake out fast and the cap put on the clean out.

Its an oil tank ,it only holds the fuel , You will need a new above ground 275 gallon tank installed .

I think it's a 250 gallon tank, so there's about $450 sitting in the back yard at current prices.

Before the previous owner was goin thru 1000 gallons of propane a winter Nov thru March .

I think part of it comes from people not knowing what renovation work really costs, they see the prices at Home Depot on stuff and think, "oh they repainted the place and a gallon of paint is less than $20 (the cheap paint, not the paint I buy) I bet that cost them $1000 at most to repaint the interior!"

Jeff, I put Richmond HW heater from Menards and never had any issues with them. 29 gallons sell for about $300

Adding to @Aaron Montague 's bathroom advise, I would also recommend you go with a 60 - 80 gallon, quick recovery water heater.  

If not a lot of Capex sometimes you just run across a motivated seller in life with a good product to sell at a great price.When you find those things lining up you have to move fast.I would make sure a large tax assessment rise isn't fixing to happen or a large increases on charge per gallon of water usage etc.Capex and utility is always the cash flow killers.

I work for a paint manufacturer and can get you paint for $5-$10 a gallon.

I've used sentricon, pumped hundreds of gallons of poison....recently though I found my new favorite product.....termidor foam on termites and had success.
