MLS to wholesale?

[Brandon B.]

My GF is a real estate agent and rehabber. Her challenge is always getting good properties obviously. I have always been interested in real estate and thought wholesaling would compliment her business nicely. I was telling her I need to build my buyers list so when a property comes along I have someone to dump it to. Obviously she would be my target customer and would have first dibs. But she said why not just list it on MLS as "cash only/investor only"? She said she has alerts set up on mls and gets emailed the minute a new listing pops up that matches her criteria. This seems so obvious to me so why is everyone stressing building a buyers list? Thanks!
