i agree -- consider, the realtor is LEGALLY REPRESENTING the SELLER -- they will NOT give you any information that's not in the seller's best interest, you, the buyer's, best interest is not a factor. and as i mentioned below, the $'s involved are to maximize the seller's offer/price (and, directly, their commision).

i also wouldn't put it past them, at all, to say some offers have come in when that isn't really true. your buyer's realtor could see through this smokescreen, depending on their experience and savvy. and a buyer's realtor is LEGALLY REPRESENTING (looking out for) you! :-)
