Seller won't let me look inside because its tenant occupied

[Scotty Hamill]

Hi, I talked to a seller that wont let me even look in the house because of it being occupied. She said after I drive by we can sign the contract. Well, theres no way I'm doing that because who knows what the inside looks like. Comps in the area are pretty low as well and its an older house. What do you say to the seller? I told her over and over I'm not making an offer until I see the inside but she wouldnt go for it.
