Seller want's a bit more than what I need to make the deal work

[William Slater]

I'm working on a probate deal the seller is motivated there is a $340,000 mortgage on the property it needs quite a bit of work. The representatives aren't looking to make a profit just cover the mortgage lawyer fees and a few other accounts totaling about 375,000. A realtor friend ran comps for me and says ARV will probably come in around 450,000 based on recent sales, not leaving much room for repairs and assignment fee. Should I just let this one go? Or does anyone have any tips on how to get them to accept a lower offer to make the deal work? I'm a newbie so any tips would be greatly appreciated.

Thanks in advance!!!!
