I'm newbie in this business. Can I use a property information from a MLS or put a MLS link on my website to advertise a property I'm interested in to buyers , before I get a contract on it?

@Jean Nkondi  , I think you really need to reconsider this strategy because of problems at multiple levels.

If you don't have a contract, then you are just acting as a bird dog and you better have a close relationship with the potential buyer because if not (ie just posting on a website), what's to keep that buyer from bypassing you completely and just going directly to the property seller?  You lose all power and control.

A larger issue, though, even if you have a contract, is what value are you really bringing to the transaction to warrant a wholesale fee if you are just finding MLS deals? Why should anyone pay you $1K, $2K, $5K, heck even $200 for a deal they very easily could have found on their own? Unless you have amazing negotiation skills and can get the property under contract way below the asking price so that once you add your wholesale fee it is still a better deal than he/she would have been able to negotiate on his/her own, then you aren't adding any value.

You should focus on finding off market deals.
