Making Offer on Duplex - Haven't Seen One Unit

[Brandon G.]

I have found a duplex I would like to make an offer on. One of the units is occupied and so I haven't had a chance to inspect that side. 

If I submit an offer, they have to allow me access to inspect before closing correct?

The closing could take up to 30 day or so (I'm getting a mortgage) and they propose a 10 day option period. Do they have to allow me access before the option period expires?

@Brandon G.

It's not needed to look at the inside.

Run the numbers and make an offer prior to wasting time touring.  Otherwise you might waste time and never get a contract accepted.  Then, once you have an acceptance at a price that works for you, then tour it.  If you discover additional items you might repair in the interior, further negotiate price down.

FYI: I have 50 to 100 offers out at any one time and I have not look at a single one of these properties.  If I get an acceptance, then and only then, will I waste my or my broker's time to tour the property.
