Seller delaying inspection. Red flag?

[Bryce Y.]

Hello guys,

I am in the option period and would like to get an inspection done. Due to my work schedule, the best times for me are on weekends. My inspector said he can do it on Saturday morning around 9am. I let the seller know. He contacted his management company, and they came back and said it would be a "huge mistake" and it would be better to do it during the week when the tenants are gone. That was exactly what he said word for word. They proposed the following Wednesday.

Immediately some alarm bells went off in my head. I can definitely understand it being inconvenient, but a "huge mistake"??? It makes me think he is trying to cover up some electrical/plumbing problems. Or maybe there are 20 people living there and he doesn't want me to see it... Should I insist on having it on Saturday?

Thanks.
