This is going down in price, but 3.4 keys is a quicksell price.

3.6 keys as a low-end is a more conservative bump with one young trade at 3.5 keys and another young trade at 3.6 keys.

3.8 keys doesn't sell that fast.

4 keys sells really slowly.

Basically the sales below 3.6 keys and the sales at 4 keys balance each other out.

Classifieds have 3 at 3.8 keys
