Recently had to walk from a 99k triplex due to a leaking heating oil tank buried next to the house.

If your house isn't well constructed, sometimes, on very cold days, the waste heat from an inefficient furnace is needed to heat the basement.

He told me that once a family of 4 showed up after he had waited 45 minutes past the agreed upon time in 110 deg Phoenix summer heat, with no call, no text, and no cell phone answered.

I would do that based on when you will need to replace the roof, water heaters, heating system, AC, etc. 

Robert,I'm from north of Boston, it's nice to see your getting into real estate things are heating up and it almost seems like everyone's "getting in".

While water/sewer is easy to deal with, anytime you are paying for heat you are looking for trouble.

What are the annual heating costs?

Does any one know of architects who do plumbing and heat system drawings.Thanks

(Plumbing, electric, roof, heating, flooring, etc. are all pretty big nuts to fix.)4) Rather than getting the "old numbers", I would find property owners in a half mile radius and start asking them about what the bills are for similar heating methods, and what the other utility bills are.5) $49.2K at 100% rented - find out what the average vacancy rate is in the area to get a more accurate idea of fully rented, and I imagine it will take a while to get there from a fully vacant building.

These two separate closings if arranged well can happen within minutes of each other at the same title company without your seller meeting or knowing about your buyer and none of them will really know how much you are making.I am sure you can find a lot of discussion threads (heated discussions dare I say) on these 2 methods here on BP to read up on.
