You are to make the purchase from your neighbor based on the number of years since the last Jubilee. He is to sell to you based on the number of remaining harvest years.

“If a man sells a residence in a walled city, his right of redemption will last until a year has passed after its sale; his right of redemption will last a year.

Indeed, your threshing will last for you until grape gathering, and grape gathering will last until sowing time. You will thus eat your food to the full and live securely in your land.
