Could Really Use Some Advice

[Account Closed]

I am new to wholesaling and have had some good success thus far locating properties yet I still don't know enough to get this thing off the ground. The partner I have been working with has shorted me on the 3 deals I have found thus far, so I decided to venture off on my own. I have a deal that was brought to me by another wholesaler in which he asked if I can help sale. The property is $395K and I have an investor that wants to buy the property for $415K. The ARV is $625K with only $40K in rehab. It's a strong deal. However I do not know how to proceed. Does anyone have any suggestions on whether I should go under contract with the wholesaler and assign to my end buyer? Or should I work something out with the buyer outside of closing?
