Yes, if you use all of a HELOC it will show up on your credit like a card that is maxed out.  

@Franklin Marte, since this is 5+ units you can force appreciation by lowering expenses and/or raising income (rents).

Do you already have the deal and private raise for the 40% down?

With my finances around 1,000 in savings and yearly income at 66,000, solid credit score with very minimal credit card debt.

Usually I'm doing them for business owners who also own their buildings so accelerating depreciation in the rental company, and raising rents on the S Corporation has been an extremely lucrative model.

We have squirrels raising a ruckus in the attic and walls of one of my Desoto properties. 

If you need to buy a vehicle in your company's name, that's a lot different then if you are just looking to segregate personal and business funds.If you just need to segregate your funds, you can just take out a personal credit card that you devote to purely business expenses and use it as a business line of credit.

We currently use American Express Serve (Amex Serve) and have a couple of sub-account cards for contractors to use.

You are also raising your maintenance costs, but I think it’s worth it to have 10 homes to refinance in 15 years vs less.

The problem recently is they are raising the land value in a higher proportion than the home value .
