Any good examples of seller consessions when buying multi-family

[Josh Quant]

Hello BP,

Getting close to buying a 2 property deal with 11 units.  The numbers work for me, I have financing lined up and the seller and I are pretty close (10k away was his last counter from mine).  My question is I really do not want to put up all the cash for the full 20% plus all the other closing costs for the commercial loan.  I am wondering what you other investors have done to limit your cash outlay at closing by potential getting the seller to help with some of these costs or other strategies used.  I really want to hold as much cash to help finance other deals I am working on.  Thanks in advance for any insight!
