The property manager had a tenant in there shortly after I took possession. 

I am planning on selling it once the foreclosure sale takes place and I get possession.   

Lastly, it is heavily preached, even on these forums, to always collect SD and first rent, in good funds, before turning over keys/possession.

Otherwise, my understanding is that if I sell to this buyer while in possession of title, I am on the hook for paying capital gains tax on sales price less basis.Thanks!

Here is what the listing says relating to titling:Buyer will receive a Special Warranty Deed (SWD) or equivalent.Property may be subject to leasehold interests or other rights or claims of various tenants or other occupants, and Buyer may be subject to the United States Service Members Civil Relief Act, or other federal, state or local law, as applicable.Buyer assumes all responsibility and liability for any occupancy, and assumes all responsibility, liability and cost of taking possession. 

For a career in Real Estate Development, is it seen as beneficial to possess a Real Estate License?

It is then their responsibility to handle the eviction and take possession.

Increasing traffic counts significantly increases the wear and tear and chance of damage to your property, not to mention the fact that you get no opportunity to vet the individuals possessing your home.

I would get possession if the property behind you, but still move forward with a suit against the city. 

Well actual one of the individuals who called from a sign sent a referral.I just recieved legal possession of one of my rentals so I wanted to place a few signs in the area.
