Answer sure.. have to check if there is a due on sale clause or if you have a PG to the orignal seller.. that mortgage stays in your name unless there is a formal assumption  Maybe the example is more challenging for a house as the property.Ex. with vacant land - seller finances to me $20k with 5% down and $1k/moCan I after 1-2 months, then resell the land to a cash buyer for $25k, pay off the original $20k and pocket the $5k?

I didn’t see your location in your profile or your post, but assume at least 17% state/federal taxes leaves you with $10k/yr.
