Sweeten the deal with a balloon in 2 to 5 years.

Since the Seller is motivated maybe you can get some owner financing to sweeten the deal up, or a better price. 

maybe there is a healthy amount of reserves to sweeten the pot, maybe not.

You're going to pay so much in fees on any loan you get for the extra 2-5 days it'd be well worth everyone's while to sweeten the pot a bit for your cash lender.   

@Alan Sweeten, there are so many rules involved in these accounts - and ignorance of the law is no defense against non-compliance.

There are combinations to accomplish this as well, you might borrow pledging only the note, you might sweeten that to the lender with a first or second mortgage on the property.

For interest rate, I would personally offer a few percentage points above what they can get at the bank to sweeten the proposition.

I thought about increasing the offer price to sweeten the deal.  

Their sweetening it up by making it sound like a great deal. 

It takes a knowledgeable realtor, and a good team, but i know you can get much better prices for wholesale deals and that helps sweeten the cash flow since you'll have a lower price point to get in your property.For ex; I have 3 properties going right now. 2 were wholesale and 1 was retail.
