Only one gas line, so I cannot add additional furnaces, and quite frankly I believe it cost prohibitive given the rents in the area.My other thought was to do baseboard heaters, I do not know the effectiveness of the heat, and it's my understanding that it's expensive to run for the tenants.At this point in considering putting a high-efficiency furnace with a thermostat that is going at the moment to the unit on the top given that it's the biggest.

Would it be more cost efficient to have window units for each bedroom?

@Adam Adams that's a great reminder and strategy on efficiency!  

Then you can compare with what you get with PM, you'll find conforming is wayyy better. at the very least, you'll have an exit strategy in-place so if you chose to go PM for the purchase, you can efficiently refi out of it as soon as possible and into a long-term, lower rate loan.Hope this helps, sorry for the length! 

Shipping containers contain a lot of metal which is known to absorb heat very efficiently and long lived.

I've dealt with BS reviews of my work place on YELP and its not fun....they are often very one side lies and there is near ZERO I can do about it....but YELP is just the platform, not the one making the reviewYou are essentially making a formal private blacklist.... and if it becomes public in some way, you will be the one left holding the bag.Cities are making lists of people based on legal documents...evictions, fines, arrests, judgments...all documented legal cases.... not personal reviews...huge difference.

Their screening and background check service is excellent... fast & efficient.
