Heat will be forced hot air or baseboards( finalizing quotes this week.

YMMV.As far as doing this w/a full-time W2 gig, my last new build was about 6000 SF heated living area w/a 3.5 car garage and is my current SFR. 

Here is the overview that he provided me:Asking Price $1,200,0009 Acres43 total approved and zoned spaces34 park owned homesMHs range in age from 1974 to 2000 but the average is ~1985Current rent $19,585.00/month2 vacant homes that need to be rehabbed (estimated $595.00 per month for each)7 vacant spots with power water and septic All units have central heating & air2 Wells with 3500 gallon water storage tank for all units Septic tanks for all 43 pads 2 Dumpsters for trash at $3,900/yearAnnual property taxes (real property and for MHs) are currently $6,100Owner says 2017 repairs were $41,000 I've owned and managed a lot of property but this would be my first MHP.

But, it's a "dry" heat".

The house I am looking at flipping has electric baseboards for heating.

Plumbing and heating was first, good choice.

2) Tenants might argue against landlord due to hvac heating, gas leak etc fixes, say it is landlord negligence etc etc.

What are your heating options? 

And more recently I had to pay 900 bucks to have someone trouble shoot a boiler/ heating issue at my rental ( the whole heating system was new).

Is it a boiler supplying hot water, or a boiler for heat?
