Top three I use are Mortgage Connect , mortgageconnectlp.com , First American Signature FASS, and snapdocs. I have close to 60 companies I am signed up with and find that necessary for a steady stream of assignments. I like to periodically review the list at 123notary.com of Top Companies. Creating a relationship with local title companies can be profitable. Aside from periodic single assignments they will hire for a full day or week when office is short staffed especially at end of month. Good luck to you !
