It drops five gallon buckets of apples every day in the late summer to fall.

They have a higher combustion effeciency and you don't have to have 30-50 gallons of water constantly heated on standby.In consideration of a rental, I would not pay between $1,500 to $2,000 for tankless instead of $500-600 tank per unit for replacement.

I'm looking at tanks online and the 50 gallon tanks on home depot are in the $600's whereas the jump up to larger sizes almost double in price!

There are so many "flippers" currently in real estate that: 1. offer way too much on a deal (an therefore get the property) because they get caught up in the heat of the moment at an auction or multiple offer situation,2. proceed to paint the entire place themselves while simultaneously learning how to paint,3. buy the cheapest possible kitchen cabinets/bath vanity from home depot or worse dump a couple gallons of paint on the 40 year old existing cabinets and attempt to straighten out some drawers4. rip up the carpet and sand the hardwood (or softwood!)

A gas therm is 100,000 BTU's.An oil gallon is 139,000 BTU's What you need to know is cost per BTU.

@Conte CuttinoMy personal approach is a 30 gallon for a one bedroom, 40 gallon for a 2 bedroom, and a 50 for a 3 bedroom on a single tank.  

Having to evict a single mother is not fun and guess what I'm not passionate about scooping up a 5 gallon bucket of dog poop when a bad renter moves out.

It's a liability issue stemming from instances when providers filled a basement with hundreds of gallons of fuel oil.

I always considered it to be 1000 gallons of $hit and pee . 

New electric hot water heater (50 gallon, disconnect summer/winter hookup on boiler)4.
