By using a Realtor, they can enter the exact address of the property you desire, and the minute it gets listed, you'll be notified. Most banks require that a listing stay on the market at least 5 days before offers can be submitted. Although I can appreciate the urgency of wanting to be first, the bank wants the competition to drive up the price. If you're not currently working with a Realtor here in Las Vegas, I'd be happy to offer my services to you. Best of luck!
