Curbside Auction House Not Like Listing

[John Friendas]

Hey,

I'm looking at an auction, with curbside buying only where you can't disturb the tenants. They claim it is a triplex (two regular units and an "efficiency unit". They also claim it has 6 beds and 5 baths. I only see 5 beds and 4 baths in the listing and do not see that third efficiency unit in the listing pictures. 

Considering it's from a reputable auction site, do I have decent legal standing if they misrepresent it? They say they are not liable for inaccuracies but the number of bedrooms, bathrooms, and unit amount seems incredibly major. Once you win the auction you have to put down a 15k deposit so I don't want to not have a chance of getting it back. The offer seems great numbers wise, possibly even without the 3rd unit.
