How to write an offer with the intention of creating an LLC

[Jon K.]

If one were to decide to start creating an LLC for each new property at the time you get the contract, what is the proper way to go about writing the offer? Meaning is it okay to put what the LLC's name will be and then sign as member with the intention of having it created immediately upon contract acceptance? I'm sure I could just have one waiting at all times in case I do get a contract but looking for info on the situation I just mentioned (just thinking I suck with names and it would be convenient to name each one after the subject property).

Respectfully not looking for opinions on the merits of titling each property in an LLC at this time.
