Paying over market value in exchange for good terms.

[Alan Charles]

I have recently been offered a fourplex that is probably 15% over market value on seller finance terms at 4% simple interest over 25 years. I consider buying on terms a luxury if the property cash flows and pays for itself over the length of the term. I am putting down 15% and will get that back over less than 3 years so I am also happy with a plus 33% cash on cash return. I would be interested to hear any opinions on the benefits and attractions on buying on terms but paying slightly over market in return? Could this strategy be a real long term way to build wealth if used correctly?
