can't remember the number, but the lot is too small for a doublewide.We are looking at buying a finished portable building as a tiny home 1/1 and possibly renting that out.  

Another option is a portable heat pump at a cost of about $200-400 per unit for 10k-14k btu.  

There's also portable units that will do up to 12-14k btu heat and cool for $200-300 but they are typically not as good as ductless systems for heating when the temperature drops below freezing.
