How to check that a lead vendor never resells your leads
Ask for the clause, not the adjective. What a no-resale clause in a lead agreement should cover, and the one thing no clause can promise.
Ask for the clause in the agreement you sign, not the word on the website. "Exclusive" on a landing page costs a vendor nothing. A written clause that says the lead will not be sold, resold or shared with another buyer, and keeps saying it after you stop ordering, is a promise you can hold the vendor to.
What a no-resale clause should cover
- Every verb, not only "sell". A clause that bans selling but says nothing about renting, licensing or sharing leaves the other three open.
- Old and unconverted leads. A lead that never answered is the one a vendor has the most reason to sell again, so the clause should name it.
- After you stop ordering. Look for wording that the section survives the end of the agreement. Without it, the promise ends with your last order.
- Where the leads come from. A vendor that buys records from a supplier cannot promise what that supplier does with its copy. Our answer on where mortgage leads come from covers the difference.
- What one lead is. The clause protects whatever the agreement defines as a lead, so read the definition too.
What no clause can promise
A clause protects the lead, not the person. A homeowner can fill in a form on another site this afternoon, or on the same site next month, and each new form is a new lead. A vendor that promises a borrower will never hear from another lender is promising something it does not control.
Our clause: Section 2.3 of the agreement
One lead goes to exactly one client. It is in writing, in Section 2.3 (Lifetime exclusivity) of the Lead Generation Service Agreement every client signs:
Source: VisionXLab Lead Generation Service Agreement, Section 2.3 (Lifetime exclusivity), the version clients sign, read 13 October 2026. Excerpt: the ellipsis marks words left out, and the section's opening sentence is not quoted.“The Contractor will not sell, resell, rent, license, share, or otherwise disclose any Qualified Lead or its data to any other client … at any time, including leads that are old, unresponsive, or have not converted. This Section survives termination.”
In the agreement, “the Contractor” is us. The wider definition, and what happens when the same homeowner comes back, is in our FAQ under what exclusive means. If you are weighing the cheaper alternative, see whether shared mortgage leads are worth buying.
Questions this page answers
No. A word on a landing page costs a vendor nothing to write and nothing to change. What you can hold a vendor to is a clause in the agreement you sign, one that names what the vendor may not do with the lead, covers old and unconverted leads, and keeps applying after you stop ordering.
Yes, if they fill in another form. A no-resale clause protects the lead you bought. It cannot stop the same homeowner from filling in a new form on another site, or on the same site later, and that new form is a new lead.
Ask to see the clause itself. Ask whether the vendor generates its leads or buys them from a supplier, because a reseller cannot promise what its supplier does. Ask whether the clause still applies after you stop ordering, and what the agreement counts as one lead.
Buying questions rather than research ones are answered on the FAQ, and anything that is not there gets asked on a call.
