Jerome,1) Run your numbers and due diligence according to your business model and analysis.2) Make your offer based on your analysis. 3) If they accept, do your post acceptance due diligence, and if it all checks out, close.4) If they don't repeat 1 & 2 until #3 happens enough you are satisfied.You can't control the other side, so don't try.

The last BP podcast on "modeling" the guest speaker talks about this, so that is a  very good point to remember.

@Bryan Hancock brings up some great points, I would say that a "typical" asset mgmt fee would run 1-3% of gross rents.  3% if it is a steep value add (in theory would require more mgmt oversight) Also, what I have found with many value add plays is that our larger investors much rather prefer to use more of the banks money via bridge loans, being that we like to have a quick turn around this fits well with our model....  

So it fit my model for getting a great deal but not some folks' criteria..
