Selling with a low interest rate

[Keegan Darby]

Hi All, 

I have a duplex in Arizona in which I’m in year 3/30 on my mortgage, which has a 4.75% fixed interest rate. 

My ROE is ~6%. I’m interested in selling the property, but would ideally be able to sell at a higher value if someone can either A) assume my mortgage or B) I structure owner financing or C) another idea I haven’t thought of. 

Recommendations on selling a property with a low interest rate to get the highest price?
