Can't see the property before an accepted offer

[James Wilcox]

I have been trying to negotiate a deal for a duplex. Both sides are currently rented out.  I was told by the realtor for the seller the following:

"Inside showings will only be allowed with an accepted offer using the contingency of physical viewing of the property within 3 days of contract acceptance." 

Does this seem legit? Seems odd that I can't see the inside of the property until they have an accepted offer. They are offering lots lots of pics, getting an extensive list of the upgrades/repairs, copies of the leases, proof of deposits, ect... If they are getting this information together that says to me they are serious to sell and are legit. However, I don't like making offers on properties that I have not seen the inside of. The reasoning to not allowing to see the inside until an offer is accepted is to not disturb the current tenants and make them unhappy. Thoughts on situation or how to proceed? Has anyone else had a similar situation.

I wouldn't be concerned... Usually they don't want hoards of people disrupting their tenants. Think about it. If every interested person walked through prior to making and accepting an offer its a waste of everyone's time including tenants. Just take a good look and you will be fine.
