If you have a good realtor they will confirm the competing offer exists. Eg. my realtor called up the selling realtor and asked for the name of the realtor that submitted a competing offer. My realtor called the competing realtor to confirm they had a client that submitted an offer. Yes, of course the two other realtors could conspire together. But, now instead of one dodgy realtor you have 2 and the probabilities go down further. Is there fraud, I'm sure there is. But, I don't think it's a significant factor in the market.
