How to structure an offer to buyer that doesn't want to pay tax

[John Choe]

I have a property that I'm in negotiations with the owner. He bought the place several years ago for $500K and has an additional $150k HELOC on it that may or may not have a balance. I have an offer on the table for $1,100,000 to purchase it and he was prepared to accept the offer but then he came back and said he would have to pay too much in capital taxes to make it worth selling. It is a rental and profitable so he sees no urgency to sell. He also said he doesn't see any properties out on the market that he would be willing to do a 1031 for. This is a commercial property and not a primary residence so how does the capital gains play a part here?

How would you change your offer to help him save $ on the taxes he would have to pay.  He does not want a subject to or lease to own.  If he is going to sell it he wants out.
