When you re-finance your mortgage you will need to contact your lender first to notify them of your plan. We recommend reaching out to your lender at least 2 weeks ahead of time.   Each of our capital providers has a different time frame required and corresponding fees that are charged to complete this action. The lender can then assist you in filing paperwork called a subordination. This subordination document will make it clear that the UCC-1 security interest on the solar system is subordinate to your mortgage. This will help make sure that you do not run into any complications during your re-finance.
