Gina The SF Bay are market is OVER Heated right now and in my observation / opinion ripe for a correction just over the Horizon. 

Also seeking to learn what base-board heating would cost to make it heated space in addition to carpeting, which would bump the number of bedrooms up from 3 to 5.

@Joshua McCarthyAre the joists burned like firewood or are they just scorched from the heat and flames?  

My house is SFR 4000 sq ft living space,it has two units, sort of duplex two kitchens, two heat pumps, seprate entrance.

Also, they will run the heat in your house at 80 degrees all winter long, and when it gets too hot, they'll open a window instead of adjusting the temperature.You should account for a large amount of maintenance, or be prepared to fight them over the costs of the things that they damage.I bought my first property with cash out of my pocket, and an owner-held mortgage note.  

Hey everyone, Hope it's a good morning.For single and multi-family properties do you typically have a gross lease where your tenant pays a fixed amount every month or a net lease where your tenant gets the water, the heat, utilities, etc. and they pay it on their own?

Utilities can be high since little to no insulation, usually old windows, older heating  and even older wiring to deal with.They usually attract a lesser quality shorter term tenant. 

i would hate to see her have no heat or hot water for the next two or three months but i definitely don't want to spend $3,000 to $5,000 on a furnace for her just to give it to the bank in a couple monthswhat are my options for this situation?
