Indeed as long as it shows up in the "business bank account" and not your personal you should be good. 

Because of so many STR places the availability for long term rentals is almost non existent.

I would suggest that you rent the property and consider using a property manager who can finance the improvements for you up front and be repaid out of the rent so you can have passive rental income over the long run. 

As long as the numbers work, locations are good, I'd rather have newer than older.

It is a TurnKey mixed use building with 1 commercial unit with USPS as the tenant since 2008, and 3 apartments filled with long term tenants.

I would recommend just taking out another bridge loan if you need more time to sell, or refinancing into a long term DSCR loan if you do not qualify for conventional loans 

They are set to go with them as long as the financials look good on the project. 

Here are pockets I focus on for cash flow:West side - West boulevard, Cudell, Clark-Fulton, Jefferson, Bellaire-Puritas, Old BrooklynEast side - Fairfax, Buckeye-Shaker (the north side), Waterloo Arts District, Garfield Heights, Maple Heights, Newburgh Heights, Lee-Miles (the north side), BedfordHere are the areas that I focus on for appreciation:West side - Lakewood, Edgewater, Old Brooklyn, Ohio City, Tremont (above 490)East side - Buckeye-Shaker (the north side), Waterloo Arts District, Fairfax*I have a graded neighborhood map of these areas as well if you would like to check it out.

Yes, the cashflow is great in these smaller towns, but im looking for long term since lot of these small towns do not grow appreciation like the larger cities.  

You could rent it out long-term or maybe as a short-term rental.
