Just a quick two questions...

What steps would I have to apply to the transaction of a renter choosing to rent off one of  my subdivided parcels. and how to lock my object so they cannot edit or return them. 

[Phil Deakins]

Nobody can edit your objects unless you set them as having permission to do so.

Nobody can return your objects unless they own the land the objects are on. In renting some land out, you are not going to give the land to the renter - unless you are really silly, or unless it's part of a private island, in which case you can take it back at any time. So, if you own a private island, and you change the ownership of a parcel to the renter, and if the parcel has your objects on it, the renter cannot edit your objects, but you can't prevent them returning the objects to you.

There are many different ways of setting up land rentals (and yeah, it's very different on Mainland from Estates), so there's no simple answer to the question.

The underlying complexity here is group membership by the tenant, and the powers that tenant is given on land owned (or set) to that group.

If, as I suspect, the plan is to put some of your own objects on the tenant's parcel, set to the parcel's land group so they won't be auto-returned, with the intent of the tenants not being able to return those objects, you'll need to be sure tenant group Roles don't include the Ability to "Return objects set to group". You may also need to disable "Return objects owned by group" and "Manipulate (move, copy, modify) group-owned objects" such as parcel audio & media controllers, prim counters, security systems, etc.

This means that multiple such people sharing the same group won't be able to return each other's stuff (which may be good or bad).

A twist: if you have objects set to other groups where those objects are intended to encroach on the tenant's parcel, you also need to deny those tenants the Ability to "Return non-group objects"... and then it becomes real important that an agressive auto-return inteval is set.
