Things have been going really well, and he's asked if I would help him convert a second unit into an Airbnb from a long-term lease.

Home is a 2 family that I converted into a 3 family.  

Anyone renting per room with success? Do they stay long? I have a 3 bed, 2 bath house in Denver Metro area I rent to a couple (no kids) for $2,000 per month. I could propose to them I rent the downstairs room for $...

There is a housing shortage as with the the rest of the state so I'm converting garage into adu.

Maybe I need to be doing the Interest only and converting it using this calculator. 

If it was not, there are various limitation on auto depreciation ( not discussed here assuming it doesn’t apply)  Property first used as personal property and converted to business use cannot use section 179.

I would like to convert an office building to enable this.Of course, you've got to have several factors to make it work. 

I thought about converting it to a 3/2 but there really isn't a way to do that in this house without some major rework. 

Adding square footage through finishing basement, attic or egress add most value for the buck, then adding a bathroom or converting a half to full.

However if i get raised ranch house, and add kitchen downstairs, It can be converted to 2 apartments.
