Seller's Agent Won't Let Me View Rental Property

[Steve Ra]

Hi,

I'm getting to ready to purchase my first rental property, but the seller's agent will not let me physically view the property because there is a tenant that is living there until the end of this month : 08/2022.

Is this common? Does this mean I have to make an offer and do the physical inspection during the due diligence period?

Any insight would be very much appreciated!
