Maybe you can do some owner carry.

Would she be willing to carry any of the paper?

What are the laws for carrying a 2nd for the down payment (i.e is there a maximum number I can carry as there is in owner financing)?  

-----Edit to add (And this may spark a lively debate, which would be awesome)The link to 123flip above with the schedule for contractor payment works pretty well on small jobs (say, $35-40k or less)On large jobs, it's not very reasonable to expect a GC firm to carry 40% until the last nail is driven and 30% until the mid-point of a job.... unless they are charging you substantially for the carrying cost of their financing.

AS it turns out neither was anyone else   ( in those days it was cash and carry).Were I see the scam's or potential for scams is the Very undercapitalized investor ( kind of like a BP wholesaler) that wiggled into the middle of a transaction..

It's no different than when the electrician shows up with his/her own labourer to send through the attic pulling wires behind them.Ironically, I know a fair amount about electricity and understand quite well how it works; though my professional experience is at a much smaller scale which you may carry in your pocket, wear on your wrist, use to access the Internet or which control large power generation systems.

It can be competitive and carries higher risk, and you would probably need local boots on the ground to find and chase the deals, but you could land some affordable properties now that would pay off big in 5 or 10 years and would provide solid cash flow in the meantime.  

On the carry back how would that work?  

I have a commercial lender that will do 80% loans - My plan (and hope) is to ask the seller to carry as much of the remaining 20% as possible.

@Mark BrownYou would be hard pressed to make any sense of a park like this.......If you start talking around 100k with seller carry it might be worth looking at seriously but judging from what the asking price relative to my suggestion, I would not waste your time.
