He would deposit the necessary funds.

The title company strokes your company a check for 15k and you head to the bank and make a deposit.

I don't think that this clause is necessarily a deal-breaker (and I could be totally wrong), but I'm taking on a hefty amount of risk in the case where I assign the contract to another investor without my own non-refundable earnest money deposit. 

Winter is always the hardest time to rent quality higher rent apts and homes.Good tenants with clean records and good debt to income ratios are already in decent places to live hunkered down for the cold winter.The place will probably sit empty till May unless you offer free rent and/or reduced deposits to entice good tenants into leaving their current places and moving to yours in the middle of winter.

I always told new agents comign to work for me you need to save up 1 years of livings expenses... it will take you that long to get your income coming in a consistent way.. or you need to keep your job and do this part time until you grow into it.those that quite thinking instant success in what is a VERY VERY tough business usually went broke and were out of the game in a matter of months.Think about it like your starting any other kind of small business.. you need capital in the bank you need capital to run the business and you need capital to live on while you are priming the pump.You also need exceptional sales skills and should spend money learning how to sell and close.you need to understand this is 24/7 ... if your going to beat your competition to the deals.And remember there are simply WAY more wholesalers and wanna bee wholesalers than there are deals in MOST markets..
