The administrative headache of having to keep extra bank accounts and tax returns isn't worth the extra headache, especially given there isn't any case law to actually uphold the validity of what the Series LLC is trying to accomplish. 

I have a property that's a Foreclosure and the bank is wanting $60k for it.

Is it a problem to get the rent in my name and use Zelle and then use online banking to move the money into that account?  

At the moment I just have the pre-approval from a bank, so I can search for properties and realtors know I am a serious buyer.

IF YOUR CONTRACTOR OR A SUBCONTRACTOR FAILS TO PAY SUBCONTRACTORS, SUB-SUBCONTRACTORS, OR MATERIAL SUPPLIERS, THOSE PEOPLE WHO ARE OWED MONEY MAY LOOK TO YOUR PROPERTY FOR PAYMENT, EVEN IF YOU HAVE ALREADY PAID YOUR CONTRACTOR IN FULL.

Usually you need to put 25% down for a commercial loan, which is $375k, and then most lenders are going to require you have more cash remaining in the bank for reserves.

If you had 200k in cash in the bank account.

I'm going to say some things that might tick off any appraisers here -- when a bank orders an appraisal, the job nowadays is pretty much lowballing the properties as much as they can get away with.

It was a savvy bank person that stopped him.

As to your next / first steps....If you haven't already, I would recommend that you start talking to lenders (banks, mortgage brokers, credit unions, etc.)
