How to limit number of properties for owner/agent

I'm using Membership Pro with OSProperty.

I created 3 plans where where people cna add one property after they have paid.

I limitted it to 1 property in the Mebership plans,

But after paing they can more then one property in the frontend, how can I limit this to 1?

Hi,
In your case, agent can post unlimited properties, but they can only publish one property at frontend of OS Property system. Remain properties are unapproved and only administrator can see them at Backend side.
