What's the best way to structure this deal, subject to, option, lease with option etc.?

[Angela Burton]

I have a possible lead on an up and down duplex, it's a pre-foreclosure here are the details:

1. FMR can be up to $750 per unit, currently rented
2. ARV around ($74,000) to $108,000
3. Approximate amount in arrears $56,000, original principal balance $76,000.
4. Payment approximately $1,161.26, variable rate floor 9.1%-ceiling 15.1%

My goal is to sell to another investor, not hold if I can help it.
