I understand that I need to account for taxes, insurance, and other costs—Should I go with a LML and then do a refi later on?  

An example of this would be mixing your personal money and LLC money in the same bank account.3.

Now you repeat that process until it's paid off.Disadvantages:It took a while for me to set up.Bank account is always low, lol.People can spend a lot with that amount of credit.People think I'm weird when I tell them DId you analyze what would happen if you moved all of that money you were using to pay off a heloc, not get a heloc and put that money in a treasury or other type of account that got you 6% interest or invest in an ETF or something lower risk?

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

I opened a business checking account with Regions.

If your company were to manage the STR in CR how do you deal with matter of safety / home burglaries? 

@Nicole GrazianoI recommend that you have a consultation with a real estate tax accountant regarding your taxes.Bigger Pockets is a great place to find a real estate tax accountant. 

Make sure your accountant specializes in real estate taxation.

Hi BP community - I'm an investor with 3 SFHs in the Nashville area looking to acquire my first small multifamily property (2-4 units).I'm trying to determine the best approach for the 25% downpayment, comparing using cash that is currently sitting in a high yield savings account to funds from a HELOC on one of my properties.

There are also additional costs of operating and maintaining an LLC, like separate bank accounts, annual report filings, tax filings, etc.2.
