Fourplex is a No-show until under contract. Is this normal?

[Brandon Wulff]

Hey BP,

I am trying to get a fourplex under contract, but the listing agent says that the property is a no-show until it is under contract.  All four units are rented out currently, but is it pretty standard to not let an investor see the property before putting an offer on it?  Apparently I can back out of the contract once in escrow, but it's a little odd that I can't see what I'm buying before buying it.  Thanks!
