Owner Finance note question

[Jose Matuk]

We purchased a duplex in an owner finance deal, 30yr note at 5% with 20% down. The seller wants to sell the note because of personal interests, however we can’t buy it out unless it’s at a 10%-ish discount. If he sells the note elsewhere, can it be called due in any way? I’m pretty sure they can’t unless we default, which we never have or never will since it’s rented out and cash flowing nicely. Any advice?

Thanks!
