Keep in mind that reliability is subjective, because the status of a home can change without notice (they get auctioned, redeemed, brought up to date, sold, etc), so sites that keep these databases cannot keep the information 100% accurate in real time.

I would ask a good agent with experience in foreclosures to represent you. If you choose the right one (track record, references, full time, etc) they can help you ask the right questions, advise you on the nuances, and save you money and headaches.

The point here isn’t just to find the property; bank owned REOs are listed and sold on the MLS. You need representation, because around here they are sold "as is" and you are required to pay the transfer tax. So get a good buyer agent to help you cover your rear.

There is probably a high inventory of REO’s in Las Vegas. Good luck.
