Standard pricing and prim limits for shop rental

What is the standard pricing for shop rental and prim limits?
i.e. L$100 for 25 prims?

I know there are no "set rules" for this, but I'd like to hear what you think is fair?
Also, would you charge the same for residential and commercial zones?

A lot depends on how much traffic they get too. Check out the rentals for some of the top places for traffic, yikes!! I saw one place that was up to 1500L per week. I'm not sure if its worth it. I get more results at places not in the most popular tab. I'd rather set vendors up in many places for cheaper prices for better results than a high lag environment.

There are a wide variety of prices out there. I personally wouldn't pay more than 3L per prim for commercial/retail or residential. In general, retail rent is more than residential. I think this is because retail rent can include very low prim alottments and the overhead in terms of time for 5,10,15 prim spots is not worth the time to upkeep unless there's a bit higher proffit margin.

As others said, there are intangable parts to rent too including theme (mostly for residential), traffic (mostly for retail) and services provided. I know people who pay slightly higher than normal rent because they like the service the landlord provides.

There's a ton of variables involved in rent and it's hard to compare 1L per prim here to 2L per prim there without taking in the location as a whole.

And of course, do take into count what the rest of the mall sells.

I would personally pay more for a 'themed' mall, where I had more chance of visitors wanting my products, even though they may have arrived looking or something else.

Pricing is pretty variable-so part of that is determining value given the shop location. Does location A at 100/25 prims compare to location B at 400/25 prims?

The math is pretty easy to figure out, take a sim, and the tier for that is 200 a month, and that is about 60k Lindens. So break even point is 15k L per week. Divide the 15k by 100 and so you get the result it takes about 150 stores/sim at 100L/wk to break even on tier. Since tier is proportionally higher on smaller pieces of land, the break even point is either more stores/sim or a higher L/prim/wk rate.

Breakeven doesn't count expenses such as advertising, events and promotions and other ongoing operations designed to encourage traffic in the shopping area.

So while getting a low price on a vendor site is always good, I'd caution store owners looking for placement to make sure you aren't placing in a location that isn't economically viable over the long term.
