Does seller's finance delay capital gains?

[Sean H.]

I have a seller that i want to buy a home from. His main concern is paying a large amount of capital gains if he sells for the year (i already know about 1031's).

Even though i could buy it in cash, if i offered to pay 60k a year for three years in seller financing. Would he have to pay 180k the following tax year, or would he be able to claim the capital gains over a three year period?
