If you were to bring other buyers and sellers together for a sale then you would need to join a brokerage. 

For example, I've worked with real estate investors to set up automated long-term marketing to sellers. 

I put in an offer on a 2 family and the seller is offering seller financing.

If you don't have money for a down payment you can always structure your offer with the seller paying your closing costs. 

I am sure it will be a motivation for him to get things done in time. 

It may just be a matter of finding the right motivated seller.

It would be cool to find a seller that will pay closing costs.

I am going to go look at it tomorrow I'm not sure if I should try to buy it myself with hard money which would be very expensive .whole sell it which I've never done and (really not a fan of whole sellers because all the ones I've meet are straight out of a seminar trying to show me "deals" that are no better than what' on the mls and often times on the mls ) sorry for the rant ...

The incentive for the seller (who's already had one deal go south b/c of buyer financing issues) is a quick close during a slow time of year and no bank headaches.

One of my clients is looking to purchase the entire portfolio (51 doors) from a seller.
