What can say, besides being laconic, my mind moves just a little faster than my fingers. Thus the short cuts. Anyway I would appreciate any input in reference to my perplexing situation.

You pretty much already have it.
Sometimes it's just first and last, sometimes the equivalent to another month's rent as deposit, and in your case, they are asking for a larger deposit for some special reason, so you could ask them why, try to negotiate it if you like the place that much and be convinced that you would want to stay that long before accepting those terms.
Aside from the possibility that they might want a big deposit because of the high value of the house and it's contents, it's also possible that they know you won't like it after awhile, as there may be some hidden flaws or problems, so they want to get as much out of you as they can.
This, only you will be able to figure out, unless you tell us where it is and maybe someone will know the place.
