Everything from foundation to the doorbell.Add on land/hardscaping.Huge variations in each, and very dependent on current state of the lot (and BIG variations in different parts of the country and urban/rural).

Bill Gulley You obviously are a gun collector; and understand the variations.

Inviting strangers with problem properties to call you means that the lonely and crazy and irrational and angry (every variation of "sad") have your phone number and an invitation to call.

I use my own variation: I think the right price is somewhere between $1 and $500,000, and I'm guessing it's closer to $1 than $500,000.....what do you think is the right price?

I have used all of OP's list (or a variation of them), except #4 & #10 (in the future I will)...

Variation from that prevents you from properly utilizing the standards you have in place.

NOTE: Though the design has a great look to it, there's no big rooflines or wall variations, which make for easier framing, etc.

I think that we need to make sure that our users who go a little beyond that and join and contribute regularly are exposed to new and fresh debates, and are able to more easily go on to see variation and new ideas/perspectives.

Last question - I would think there would be variation in the number of cards sent for each area.

I like the idea and want to bounce a little variation off of you tying it back to BP.The sharing and collaborating between everyone may end up being the best part of your idea so everyone else can see it as well.
