I started my LLC last year and this will be the first time I show income and would like to finance my deals based on my LLCs income and not personal in the future. 

I personally invest out of my llc.

Hi BP's,I'm an out-of-county investor, in the process of purchasing a property in PA.Closing is in two weeks from now, and I'm not sure if it's better to form a new LLC in PA (and if I have enough time to do that)or if it's better to use an existing one I have from a different state (I have one in OH and one in IN).What would you suggest?

The Properties in Ohio are in an LLC owned solely by my Wife and they are all owned free and clear.

If you do seek checkbook control via an IRA LLC or a Solo 401k, then the custodian is removed from the day to day transactions and ongoing fees are typically lower.

Purchasing a condo in Tennessee, but we live in another state, do you recommend getting a LLC in Tennessee or our home state?

You do not have to formally structure it as a partnership or form some business entity like an LLC.

Since I don't have an LLC, is there any concern/ caution/ potential future issue if I transfer funds to my personal brokerage account? 

I’ve only got a dozen rentals so far so I haven’t bothered with an LLC yet.

It does not require personal income and if you have a LLC, it can be in your LLC and best part is that it doesn't show up on your credit report.
