90 year old client wants to sell land on a 25 year installment plan. Total gain is $600,000. Is this advisable? Also, he wonders how his heirs would collect the remaining installments.

I thought usually it was best to let your heirs inherit the property to get the stepped up basis, but this client has a buyer that wants to make a purchase because he wants to do improvements on the land.

I don't understand how the transaction would be at his death for the remaining payments. Does the buyer have the title, or do the kids inherit the property until it is paid off?

What is the best plan for this type of transaction?
