Should depreciation cost basis be put in an offer to purchase?

[Andrew Bober]

I had an unfortunate experience with our buyer's agent in OH recently.  The agent walked away from me and the deal when I asked him to include time limits in an offer, as well as a price breakdown to establish depreciation cost basis.

1. Land
2. Building
3. Personal Property
4. Land Improvements

Is what I asked unreasonable?   I was told "It's not done that way here."

Does anyone else put the cost breakdown in their offers?
