Lease to own query...

One of the options we’re looking at, maybe as early as next week, is a “lease to own”. Specifically a one year “triple-net” of $2000 where should we exercise the right and move to purchase the property at the end of the first year, $10,000 of those lease payments would be “credited” towards the previously established purchase price.

I don’t have any experience in this area and am wondering is that % about right, too low, or maybe even too generous?
