Or just go knock on the door and see if get an answer, if so what to say?

I want to make an attempt to door knock but not quite educated on it yet..

I thought if you took the first floor and knocked down a wall and remove a kitchen you can turn 2 units into 1 unit.

Be sure to knock loudly, ring the doorbell, announce yourself loudly as you move through the home.

The building costs, especially now, are too high to knock it down and build from scratch.

@Angelo Palazzo not in my limited experience (knock on wood).

You can also door knock and talk to the neighbors, but during pandemic this one is less likely to succeed than last year. your mileage may vary though.

Side note: We listed it for sale prior to renting(we were still working on the title situation) and had people knocking down the door to purchase, some over list price.

The IRS doesn't even see your loan until they come knocking in an audit :). 

This scenario improves cashflow, and will do so even more if we refinance (currently at 4.125%, but there has been talk of that we could knock off one whole percentage point in our situation).Of course with the closing costs to be paid in a refinance scenario (est. around $10,000), we would be semi-committing ourselves to a more long term hold scenario.
