Portable or built in?  

If you want to go electric, get a few ductless systems or portable units that operate in heat pump mode and you will get 2-3x better efficiency.  2 ton ductless systems are about 900 or so on ebay and 1 ton portable units are about 200-300 online.

He introduced me to a partner of his who claimed he had access to portable mobile home units across the country and in which case I could invest in each rental property for an investment of $10-15k each and receive a residual passive income of approximately $2.5k/month. 

Hi all,I was recently introduced to a real estate investment opportunity by an old friend (who claims to be a gap funder/broker).He introduced me to a partner of his who claimed he had access to portable mobile home units across the country and in which case I could invest in each rental property for an investment of $10-15k each and receive a residual passive income of approximately $2.5k/month.The deal would be a completely turn-key investment, as I would own the note on the mobile unit, and I would not have to do any maintenance, etc as a normal landlord would.Everything sounded great on paper, but here's where a got overly suspicious:1) The one-page, loosely written contract he provided did not disclose any address or rental property infornation, nor were there any lease/loan terms or agreements set forth.2) The urgency to close the deal.

They make portable heat pumps now and you could suggest those to your tenants as a way to cut down on heating costs.

Ideally in five years, we'll have five or so properties and enough income from them to live on and husband can manage (maybe) while I continue freelancing (the portable and most favorite of my three jobs) and our kids go to school in America.

I haul equipment and run a crane for a portable mining operations company.

@Harman N.I would either extend the ductwork into the garage or install a mini split or portable heat pump.

We told her upon delivery of the portable heaters, and one more time the heaters draw too much power to be on the same circuit and should be spread through the house.Any advice on our responsibility as a landlord, and how this may play out if we go to small claims court?

They actually no longer live in the house and actually live next to the house in portable trailer.
