Junaid sb, this is what precisely these real estate agents in those shiny offices do. The are living examples of such a scenario. Nothing bad in that as long as fair conduct. This is in practice since decades.
-- Have a few investors at backing, willing to pay token or full payment in case buyer not found in 30 days time (to play safe).
-- Market is full of sellers who want to sell on urgent basis and that goes cheap, sometimes up to 10% less on same day cash offer.
-- Pay the Token with a 30 Days Time for final payments and transfer.
-- In those days, sell that and get the transfer directly on buyer name.
-- 2% commission in addition as part of the deal.
The term we often here 'Investors'

The above of course represents the most common mechanism, as far as keeping it fair. That requires it to be pretty much a full time job. Make sure all documents verified (Transfer Letter, Any outstanding dues, litigation, NDC etc.) at the time of Token Payments. Street Smartness if a pre-requisite to get into this.
