This last weekend we replaced the inworld vendors with Casper's extended vendor system specifically designed for home rentals. They are easier and more intuitive to use than the older product oriented vendors. Visually they are almost identical. Obvious features are red accented buttons rather than blue, and FEWER buttons. 

Merely focus the picture of the home that interests you, click and get a teleport map, teleport and you will arrive at the home's rent box.

You can pay the rent at the vendor of the home you desire. Right click the picture and pick your lease term. The rent and prims displayed in the vendor will be identical to the rent and prims set in the rent box. No more surprise variations!

The system includes kiosks. Kiosks provide available-home browsing through a website. Tenants can also pay their rent through the kiosk. These have been placed in rent offices and will appear in community locations, pools, docks, beaches and so forth.
