Ok, I truly have to give a plug here for @Michael Blank 's Syndicated Deal Analyzer. I don't even know if this plug will even be allowed but i have to try.
I have now been using his tool for about a week now and let me tell you, I LOVE it. I was using David Lindahl's Big Profit Finder which is good, but I really don't think it is worth the $9 per month price tag. Glad I was on a 2 month free trial. With Michael's tool, you can do everything that Big Profit Finder can do and a whole lot more. I highly recommend anyone needing to analyzes numbers for multi-unit properties to check this tool out.
PS: I get absolutely no compensation for this in any way. Just love the tool. :)
