Of course I called the city to make sure that things were code compliant and called pros to ask questions, and got all of the relevant inspections, but seriously, YouTube..There were a few things I did hire out as an owner is not allowed to complete their own gas fitting work or install a new electrical panel and main power service.

Either add on a flat fee for monthly utilities for each occupant, or do it the hard way and divide each bill up equally (internet, gas, electric, and WSG (water/sewer/garbage).

As a little background on the property- the home is a legal 2 family, but includes a ~1500sq foot garage with separate gas/electric meters, effectively giving me 3 units.

The large family room has a vaulted ceiling, gas fireplace and sliding doors leading to amazing pergola in fenced in yard.

It also needs gas, water, and electricity (you can skip the gas if you go all electric) and the gas and water supply must be direct connected to the meters.

The gas and electric meters have been removed.

I have a multiunit property (8 units) in NC with central water, gas, electric. 

Cost of new HVAC plus ductwork, including gas/electric lines w/ permits for a row home along with removing radiators you are probably talking 12 to 13k.

I would talk to a gas insert guy (or maybe electric to save money).

If you pay heat they may have a running invoice for oil/ gas the last year or you could call the gas company for an average.
