One thing that I’m seeing it that large multi unit buildings beyond the 800k mark are all on a boiler and paying to heat the entire building ruins the numbers.

If the tenant complains there is no heat, you should respond.

@Mark Ross  don't include heat in rent on an ongoing basis. 

Quote from @Carlyn Chism:I agree with Chris on a lender that might be a scam or make you may so much money interest because of the low credit score that you make $1.00 on the flip or no money.  

I have been in the search of lenders with low or no minimums for purchase/ refi. 

The first house that I bought was 17 years old, 3 br, 1.5 bath, brick ranch house with hardwood floors, Andersen windows, ceramic tile baths, gas heat and a brand new roof. 

The property does have heated radiators through out each unit. everything is separated for each unit electricity, gas, and window units in each property.

Heating costs go up in winter, as does electricity due to the reduced natural light and more people indoors.

Also, what are some other low cost amenities that I can add to my STR that will yield a higher ROI?

@Collin Hays My favorite that came in at 6am one morning when the nights low temperature was 58 degrees and the high temperature was to be around 75 was the following.
