@Troy DeLong every investor situation is different so it's hard to answer without knowing your particular needs, I would definitely recommend you to consult an attorney and a CPA.
The cost of creating an LLC being "cheap" is not something you should consider, you should create your LLC in whatever state you're planning to buy your properties, otherwise, you gonna have to file some foreign affidavit in every state you own property in.
Then, it looks like you're looking to hold 1 property per LLC, some people do that for liability purposes, I personally think it's unnecessary unless each property is worth several million, the added cost will burry your return. I personally pool up to 50 SFH per LLC and set up 1 LLC per Commercial property, I also set up 1 LLC in each state I'm doing business in to simplify my accounting.
If you really want to keep every property separated you might want to take a look at Delaware series LLC.
Depending on the size of your portfolio you can consider setting up a holding to regroup ownership of all the other LLCs.
Look into the tax consequences (LLCs are pass-through entities so you might want to set up a c-corp etc...)
But once again, there's way more to consider than just the cost of setting up the LLCs, it's a bookkeeping nightmare and you're going to be surprised when your CPA hand you his invoice.
