Anyone have experience converting a property with individual gas heat to a central electrical HVAC facility?

Our property manager has handled calls like a clogged toilet, leaking pipe, a broken mini blind, broken shelf in the fridge, blender not working, A/C not working, the guests can't figure out how to operate the TV, meeting with repairmen, pool heat needs to be turned up/down/on/off, neighbor used our trash bins so now they are full and no room for the guests' trash so the PM has to go pick up their trash and haul it away, light bulbs are blown out, etc.

Per the seller, the property is a fixer upper, no central air or heat only window unit.

Being that you live in a cold climate where heat is required by law.

Hey Glen,I recently had a house I converted from oil to a heat pump.  

Now I am looking for a licensed plumber / heating specialist to perform the following:-pressure test on gas line-interior gas plumbing-install gas furnace-modify the existing ductwork-install 1-2 gas water heatersIf you have any recommendations for a trustworthy plumbing/heating person in the Cromwell, Hartford, or Middletown areas, please let me know.Greatly appreciated!

You don't pay for heat or trash or anything like that?

I suggest that you get a few good reliable vendors for plumbing, painting, electrical, heating, carpentry.  

The reason why is maybe it from the 1900's and they did a complete cosmetic overhaul and it looks amazing, but what about the pluming, wiring, foundation, roof, supports, heating and air conditioning, and other things that don't have anything to do with the way it looks but might have a little to do with your bottom line.

You need to calculate the utilities to light and heat the hallway, landscaping, snow removal if you have sidewalks and parking lots.
