motivated cash seller

[Jacob Cash]

so I have a motivated seller who wants to get rid of a duplex that will currently get around an 11% cap rate if bought for the price I have talked them down to. i want to buy and hold the property myself for a good cash flow, but I don't have the money to put an investment loan down payment (20%) on the property. I asked the seller if they would be interested in seller finance or a seller carry-back, but they said they want to use all their proceeds of the sale to pursue another investment. so no seller finance.

Does anyone have any creative solutions that will benefit the seller's situation but allow me to get into the property with 0% down and without using hard money lenders?
