well.............he’s 70 and says he can’t afford it. Since the property taxes are $24,000 (80 acres), he might be telling the truth.
Golly. Does he have kids he wants to leave the property to?
If not, maybe you could negotiate a “lease to own” contract, where the first year or two of rent goes into escrow for the down, then then rental payments become mortgage payments. That way, you could plan to upgrade.
