such larger scale renovation project, not easy to DIY.
you are looking at to redo all HVAC, possibly most of the plumbings, replacing all paneling with drywall, and new kitchen new bath new floor.
I been thinking if this is my project, how would i approach it...
once open up the walls, its like open up a big can of worms, you will be dealing with insulations, asbestos, mold and everything else you ever think of.
I say you better budget it 50k/door, if not more.
-- HVAC - looks gas service is availible.
1. cheapest way to heat and cool is baseboard heat and wall mounted air conditioners, no duct works needed.
2. next option is packaged units, such as this one, , these are self-contain units, can be install inside a closet with small open to exterior wall, and limited duct works for air flow, withouth tearing all the ceiling and floor joist down,
3. stand split systems, you will need to run linesets to either the roof or on ground, $$$$$
