It is very similar to an Owner Buyout except you are buying out only a portion of your Unlock Agreement.
To provide even more flexibility, the Unlock Agreement allows you to request a Partial Buyout at any time during the term.  The process is the same as with an Owner Buyout except you identify your intention as partial and let us know what portion of your Unlock Agreement you want to buy out.
All Partial Buyouts are subject to our approval, which will not be unreasonably withheld.  There is technically no limit to the number of Partial Buyouts you can do during the term, as long as you are willing to pay for the required appraisal each time (and a home inspection if needed).  Unlock may decline a Partial Buyout if the remaining Unlock Percentage would fall below 25% of the original Unlock Percentage.
See the Unlock Product Guide for more details.
