How to wholesale without access to the property?

[John Horner]

Out of the many wholesales I've done in the last year, we have a solid one now where the sellers attorney instructed her not to give us a key before closing.  We have multiple interested buyers who want to see the property, but she is insisting on meeting  anyone there instead of putting a lockbox on the property.

Luckily we have the money to close before we start showing it, but at that point we may as well put it on the MLS.

Has anyone run into this before?   How did you bypass it?
