Basically the first thing that goes wrong will probably cost $500 just in materials -- think water heater, sink, heating unit, etc.

Ask your landlord for a property inspection and ask that he increase the heating to the legal standard, which is as follows in NY:"Landlords are required to follow the temperature guidelines below: From 6 a.m. to 10 p.m., the indoor temperature must be at least 68 degrees if the outside temperature falls below 55 degrees."

Hey there- I’m getting a rental ready for market and two bedrooms have no heat source so I’d like to install Cadet style in-wall heaters.

Most states only require a landlord to supply heat, not ac.

You start off with the extra expense of heating and snow removal. 

I provided the new tenant on the 2nd floor with a hotel until the pest company could could and perform a heat treatment on the house to kill the bed bugs. 

There is no ducted heating.

I'm looking at an older Victorian foreclosure, the heat is oil.

In addition to lead and asbestos, you should assess the current and former heating oil tanks, test the water if there is on-site well and evaluate the septic system.   

Winter heating brings electric up to $150/mo.
