Atleast that way she’s heating the house for me

Taking $50-100 less per month on a 6-8 month lease is less than one full month of vacancy, not to mention added costs of vacant maintenance (heat, security, etc), so it is a no-brainer.I would suggest you see what the market rate is *right now* for units similar in location, size, and amenities to yours, and then consider taking 5-10% off of that figure, and go until late spring/early summer with the lease.

Nope, just your basic heat pump.   

A couple of things I have thought about are adding heat to the warehouse as it is currently not heated and I've got a bathroom and laundry that are on the same level as the warehouse.

You found the tiles and there is more; but it is not a big deal, unless for example, there is a forced air heating system and you decide to do an extensive re-model.

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.
