HELP! Seller wants to sell, but doesn't want to pay the taxes

[Kevin Brenner]

Looking for some BP tax experts/investors on this one:  

I was cold calling potential sellers the other day and talked to an older gentleman who owns over 25 properties in my area.  He has considered selling in the past, but doesn't want to get stuck with all the capital gains taxes.  I mentioned how he could avoid some of the tax through seller financing. 

I understand that with a long note, the payments would be relatively small, which would greatly reduce the taxes for the seller by limiting his exposure per year.  Are there any other tax benefits that I'm not aware of (from the seller's perspective)?  Generally speaking, what terms do you think I should present to him?
