He said that he is leaving at the end of September, and he just use the one-month deposit as the last month rent.

Message me back if you can beat, match or come close to my current terms.  

How are you so organised with info and links to match?

I'm thinking an additional (higher) security deposit?

Assuming rents are market and not inflated with no waiving of security deposit or first months free then net without immediate capex might be somewhere around 145,827.That would be around an 7 cap for a C property if you are evaluating properly and it's not really a D at 2,100,000.

-- I have CASH BUYERS ready to go NOW; In addition, I also have a waiting list of tenant-buyers with deposits and/or option consideration ready to go in the BLOOPS- Brevard, Lake, Orange, Osceola, and Polk Counties.  

You'll update your assumptions if/when things don't match up then determine how to approach it with seller 

The biggest hiccup I have is that most of the work is not in repairs as much as it is in updating and upgrading to match the neighborhood.

Not only was I screamed and yelled at, but I was threatened to have my deposit withheld from me.

We Bought 2 matching Duplexes in Feb of 2014 and paid  $332,000 (+ closing costs) for both of them.They needed approx $37,000  ($18,500 each) worth of rehabbing and were occupied with tenants paying $1,000 each.
