Where the requirement lives
In the loan agreement's insurance covenant, the closing checklist, and for SBA loans the loan authorisation. Equipment and vehicle financing puts the requirement in the security agreement. Each names what must be insured, for how much, who must be named and where proof is sent. The contract checker in the wallet reads the clause and lists each item against the policies you hold.
Why the lender's name matters
A lender named as mortgagee or loss payee is paid directly after a loss to the collateral, which is the whole reason the bank asks. A certificate that lists the lender as a holder does nothing; the endorsement on the policy does everything. Ask for the endorsement, keep it in the wallet, and the live certificate will show it.
Flood, the requirement that surprises people
Property policies exclude flood. If the bank's flood determination puts the building in a special flood hazard area, a separate flood policy is a condition of the loan, and the bank will force-place one if you do not buy it. Federal program policies carry a waiting period, so a closing date can be missed; private flood often starts sooner. The comparison on the flood match guide shows both.
Renewal tracking without the letters
Lenders track insurance through tracking services that send letters when a renewal is late. A live certificate link from the wallet, given to the lender once, shows the current policy at every renewal and notifies the lender when anything changes, which is what the tracking service wanted in the first place.
