Appraised Property had very similar improvements to those made to Comp 1 in 2015 including a new roof, 3 new hot water heaters, 3 new gas burners, 3 updated kitchens and 4 updated bathrooms.

Which I had set out to find having a purchase price I could do, with steady and decent tenants,  separate meters on gas/water/electric, newer roof, newer plumbing, and  negotiating a lower asking price that they accepted.

I would say that you need to determine (in no particular order) regulations on rehabbing, sewer/tap condition, asbestos, mold, whether you're in a historical location or not, landlord/tenant laws, gas line condition, etc... all those things can be detrimental to your expense line.Hope this helps a bit. 

It had been converted to a crummy triplex at some point in the 1960s, with separate electrical and gas.

The utility companies will come pull their meters and cap any gas lines.

Each unit has its own electric and gas, and there are 2 exits in each level, although there is no kitchen in the attic unit.

Add the gas appliance coverage for just the furnace and hot water heater at $12.00/month from PSE&G. 

This may be the case is there was a property there previously then it was demolished, you may have to upgrade those connections depending on what was there prior, i.e. the Sewer, Gas, Electric, Water, etc.. an example would be if a SFR was there previously then was demolished the new property will require changes when building a Duplex, meaning more on your Soft Cost budget.4) Is this a dirt lot or a concrete lot?

No air conditioning installed, 1 window AC unit in each of the units.Currently the heating(gas) bills can go as high as $800 in the coldest months and as low as $30 (tankless water heater) in the summer months with single pane lead glass.
