The property will have two key Target Markets: A house hacker as bottom unit could be a great rental, Air BnB.

Those machines are more than capable of breaking through the frost.You may notice some settling in the surrounding ground area come spring, as the ground thaws and any air pockets around the egress "cage" fill back in.

You want the place air and water tight!

--Sometimes, humidity or dampness (water vapor) in the air can supply enough moisture for mold growth.

As far as the window is concerned to make sure it is large enough also you might want to consider purchasing 2-3 Story 25-foot Portable Fire Escape Ladder like this if there is only one window.

We currently live in this unit but ready to move out to see more cash flow.What do I need to know as far as the new air bnb restrictions that just passed?

I could air bnb, or rent it out for profit and still eventually sale.

I live in another state, and run my air bnb remotely.

The expense of these boilers is relatively high and the logistics of venting and providing air supply to them seemed too trouble some.  

In some parts of town the value didn't drop at all and in others, houses are barely going up on the market so value is still up in the air.
