12, 8, 6, ... 4?, 3?, 2?, 1?, none?

In the wake of events these last 24 hours, I decided to cut down on the number of properties I would take (IF I end up taking any of them) from this latest deal. While the initial quantity really attracted my interest, I quickly realized it would not be feasible to take all 12 properties. After that, I narrowed the list from 12 to 8. Even then, I would be taking on a huge amount of debt (and risk) even though I would conceivable make a nice profit in the end. However, given the circumstances and more analysis, even the 8 properties wouldn't work for me. So, I then tried 6 properties, and again even though they produced nice income at the end, the risk, time, and upfront debt was just too much resources to endure at this time. Plus, given the procrastination and non-disclosure of required information from the seller, I have narrowed the list down even further: 4 properties. The four properties in question would collectively give me an average $3,500/mo cashflow (after enduring some upfront risk/debt) over the course the properties would be owned and/or controlled by me. It was after making this analysis that I decided to just go ahead and break the 4 properties down to 3, then 2, and finally 1. The following table shows the resultant figures of my analysis if I were to keep just the best property, then the two best properties, then the top-3 properties, and finally all four properties:

	Keep 1	Keep 2(a)	Keep 2(b)	Keep 3	Keep 4
Initial Investment	$8,750	$13,750	$17,500	$22,000	$29,500
Net Profit	$49,024	$91,769	$78,603	$121,982	$143,647
COCR:	460%	567%	349%	454%	387%
COCR Annualized	115%	74%	95%	65%	59%
Average Cashflow (Monthly)	$1,816	$2,238	$2,911	$2,975	$3,504
Average Cashflow (Yearly)	$21,789	$26,859	$34,934	$35,702	$42,043

Looking over the figures, I am leaning towards just keeping the one property, or the two properties under the heading "Keep 2b". These appear to give me the best bang for the buck in the shortest time possible. Now, will I even get any of them is the question. :-|
