I have an elderly person in the property and the heat is making them very ill.

I have listened to both BP podcasts for a while, as well as some books and other resources for some background knowledge on how to get started.Background:I am from the Kansas City area (Grew up in Rural Miami County).

.- Just curious if your monthly expenses include property management, yard maintenance, and anything that the tenants don't cover (check the current leases to make sure heating/cooling/water etc is all paid by tenants).Good luck and let us know if you have any specific questions.Joel

An example would be if the Landlord does not repair the heating system, and it is below 50 degrees. 

This tenant would be happy to pay $300 for this space as opposed to $700 for one that has access to a bathroom.Parking - yes there is plenty of parking on-street during the work day, and we are currently adding onto the driveway to allow 6 cars to park.Utilities - The heat is just one huge forced-air system for the whole building, so we'd have to include that.

@Evan Young  No doubt this will trigger another heated debate, but what you are proposing is called real estate brokering. 

The odor goes inside the walls, the attic, underneath the building, inside the furnace, heat ducts, electrical conduits and even after cleaning everything and painting there are times you can still smell the odor.

If you turn off the ac during the day and the temp rises significantly in the unit, when you turn it back on the unit has to work much longer and harder to remove excess heat.

Get a couple of quotes from a heating and AC company. 

I would also remove oil and replace with another heating source.
