Ways to structure a seller finance deal

[Ryan Cleary]

I have a property I would like to sell:

-Market value: 450,000

-Purchased in 2020

- Mortgage has $153k left at 4% (conventional)

The market is slowing down a bit and since I no longer would qualify for conventional loans, I am considering offering seller financing to generate some interest and get the best sale price.

I would love some ideas of how to structure this properly. 

To my knowledge, it is better to have a buyer assume the mortgage, I just dont know how the rest of the terms would be.
