These tanks, and direct vent gas furnaces/boilers, can be plumbed directly through the side of the building (foundation wall, sill plate, etc) provide the exhaust exists the required distance from an operable window, door, or other air intake.From an energy efficiency stand-point, direct vented fixtures are preferable as they are not taking their supply of combustion air from the conditioned space of the building (are you have already heated), causing colder, external air to be drawn into the building.Additionally, as Pat has pointed out, direct vented fixtures reduce the risk of natural gas/propane or CO being drawn back into the conditioned space of the home. 

Would need help picking paint color, furniture, linens, etc...

Also, in my experience, home staging and furniture rental always does the trick (for me anyway).

On the other hand, if your supply valve/hose breaks underneath your sink, or your tub overflows, it's the units owner's responsibility.

If you have multiple units on one system, and this being New England, I'm guessing it is an older building, you are most likely going to have to open up walls, and replace a lot of the supply and return lines so that they make home runs to individual boilers, etc that you will be installing.  

For example, the money used for the original purchase of the property is no more or less valuable than the money used to purchase supplies at a later date.

America after World War I stockpiled 70%+ of the worlds gold supply and his caused capital flows to pour into the U.S.
