How can I pull out cash of property sub2

I have a guy would does not want his 3 family in boston,ma
he only owes 244k, he has equity of about 175k in it
Is there a way for me to make a deal
Im sure he’ll cut me some of his equity
but not sure how to structure the deal

any suggestions

Have him refinance and take his cash out then take it sub2. Or take a loan and pay him off.

You could also have him put a 2nd lien on the property for the part of his equity that you would be paying him for.
