Quote from @Kevin Kim: Contact the housing office and let them know you want her out.

You can deduct all realistic business expenses, including mileage, meals, allocated cell phone use for business purposes, home office space, etc whether you own the flip in an LLC or personally.

CBRE’s latest survey reveals a potential turning point in the office market.

I still go to the county clerks office.

And I'm projecting here, but it seems like the banker went through the list of named loans in their head like FHA, VA, jumbo, etc and wouldn't have "DSCR Loan" in a drop down list to select, as if you were asking for a FHA loan, so was stumbling a bit.I'd maybe suggest asking more about how the loans are underwritten when speaking with a mortgage officer and if saying "DSCR Loan" doesn't seem to get you traction, maybe ask something like "well, I was hoping that my request could be looked at from a DSCR perspective as well as any other underwriting you do for the best chance at approval because of XYZ."

I worked for a man that made a deal on an old Post Office (actually the land).  

Tiny homes are going to be a different clientele...

I made a few small improvements to the landscaping, I bought a few new appliances, updated a few fixtures, added blinds to the windows, minor drywall repair/paint, and marketed the property as a 4th bedroom that would make great home office/den instead of a 3 bedroom plus office/den.What was the outcome?
