First and second floor are both 3/1, heated by the same oil furnace, third floor is a 2/1 with gas heat.

I contract out myself doors/carpet/ granite/ heating and cooling/ floor refinishing. 

With that said, I have a house off washington, that iv lived in for 3 years now, I am all in for around 1050 a month, my upstairs pays 1100, and for the first few years i had a roommate for 350, which covered heat and cable, so I was happy just living 100% for free, it wasnt worth packing another guy into a room and wrecking my quality of life for an ever 350 a month.

The article includes heat maps and other statistics related to rent/sqft ratios in different rental markets throughout the country.  

In the process of potentially buying my first BRRRR property which has oil heat.

Heat and hot water included (no individual meters).

Add a few amenities (heat, lights, insulation) and it will cost another $1000.  

I've used this resource titled "Rental Returns and Cash Flow Heat Map" from Realty Trac but is there a better resource out there with more information?

I'm looking at a home with a gravity heater in Minneapolis and know nothing about them.

Should I not consider the home because of these? Seems like it can be very expensive to replace.
