Also, our fridge is leaking and our water randomly shuts off and we barely get hot water?

The tenants lease she signed did not include her having to pay for oil but just electricity, (1st floors heat and hot water are fueled by oil) Me not being a home owner before and or landlord thought nothing of it until winter came along and this oil bill became very expensive.

A lot of investors carry themselves with an air of superiority that is off putting to most people.

Their company takes atmospheric air and separates it into separate components. 

Also - start hooking up with flippers in hot zones in KC - east of downtown a bit, and south near 71.

It came with a set of tenants (a middle age man, and a middle age woman and her boyfriend) who have been decent.they do pay but it has been late I usually get it on the 5- 10th every month.this month I have not seen It yet its the 13th. another thing I should mention its heat and hot water included and they are paying $500 below the market rent. should i evict them and find someone who can pay on time and the market rent?

Like @Matthew Nicklin said, double check the rent amount as "nice area" "$280k value" "no repairs" and "$2100 rent" are pretty rare to find in most hot markets...not sure what market you're in. 

It was built in the 1950s and has a boiler for heat and window units for air.

I convert all of my houses to central heat and air as well.

Hot water potentially if it was under $2,500 179 doesn't work on residential rental and it's connected components.
