How to negotiate a deal that benefits both myself and owner

[Yesenia Padilla]

I recently got a call back on a letter I mailed out. Owner is set on a price but I am actually really interested in purchasing the property and holding on to it for a rental. It's a 2 house on 1 lot, up in coming neighborhood, back house needs to be rehabbed so I cant get a conventional loan. Arv is roughly 340k, she owes 70k. She wants 325k. Needs about 15k in work before a lender will lend on it. Trying to think of ways I can save owner money so she will reduce price. Other then doing a fsbo how should I try and negotiate this deal? I ran numbers and the deal would make sense for me if I can get it for under 300k but preferably trying to get it around 290k. Thank you in advance for your help.
