No Property Walkthrough

[Joaquin Moreyra]

Hello!

The seller will not do a property walk through until we are under contract as he doesn't want to spook the tenants. He is saying that he doesn't want to have numerous people who are interested going through the property with the tenants there. It is a multifamily and I have only seen pictures of the inside for one of the units. 

Is this a red flag? And if I cannot do a walk through prior to submitting offer, should I pass on the property? Or is there something else that can be done to assess the property  BEFORE submitting offer The? The numbers do workout and look good. 

Thank you!
