That would be around $90,000 sitting in a savings account!

If you have a budget and allocate the costs, not sure why you would need a different bank account for each?

I signed up with them about 3 to 4 months ago, then found out how expensive the loan was to get going with them and told them that I would self finance it instead but they had to cancel the loan first...they use a company called Special Financing Company..the person I spoke to at REI his name is Paul, he said he would take care of canceling the loan, but a month later I realized that they were pulling $599 out of my bank account.

If youre wanting to make a cash offer, all I can say is that Ive never seen a competent seller/listing agent accept a cash offer without proof of funds, meaning a bank statement or similar document(s) showing liquid cash for closing.

Are there investors here in Texas that have utilized and would recommend banks they hold series LLC accounts with? 

@Anita Z.I recommend finding an accountant who specializes in real estate taxation, tax planning and financial planning.

Now that we are 10 days from closing, I am talking to loan officer to get the Closing Disclosure so that I can know the exact cash to close (I need to move money from brokerage to bank account) and he is mentioning about 2% IPC limit. 

I purchased the property from the Shelby County Land bank. 

You can either write checks or make ACH transfers directly from the HELOC if your lender supports that, or transfer money to your checking account as needed to satisfy your cash draw needs.When I had my house, the 1st and the HELOC were both with the same bank as my checking account.

I have bank accounts for every LLC, so if I'm shutting down an LLC, I'm also shutting down the bank account and moving the money out.
