Relocation & mortgage companies that actually give you leads?

Has anyone ever worked with relocation companies that have actually given leads.

I'm currently on the hunt for these and researching big ones, and smaller esoteric ones as they add up.

I know many of the relocation companies operate on the pay per close model. They're out there. For instance Cartus is a big one that works with companies like Dell, Nike, Raytheon.

I know the mortgage companies give leads but it can be a gray area with RESPA if they require referral fees.

I understand a lot of these are invite-only, gatekept, but I'm wondering if anyone was able to get in with any good ones that fed leads in your area.
