The deal was contingent upon 60 day due diligence and a clean Phase 1 environmental assessment.

I clean it up a little and sell it for more and a higher interest rate.

My local Airbnb rep said the algo does consider cleaning fee too so try to be lower or even with your competition. 

Once the building is sold it generates a Section 1231 Gain and that can be offset by release of the passive losses from the syndicate that have been carried forward.

You need to look at return on equity, how much cash flow can be generated putting your equity to work vs the cash flow this property will produce.

Can you generate a report in Buildium to download a CSV file to upload transactions to Stessa via the Stessa CSC uploader?

Very clean format. 

Do you turn in clean PLs on each property?  

Looking for a high LTV DSCR option given this property should reasonably be priced nearer to or upwards of $425k given the cash flow its generating.

Yes, there are bad areas and appreciation probably won't happen...but rents are not declining, there are great tenants if you screen correctly, and even the C neighborhoods generate great $.
