Is the line of credit different from refinancing the home that is free and clear? 

Assuming you go the HELOC route, another option to reduce your costs assuming you have decent credit is to look at credit card balance transfer promotions.Back in 2003-2004 I had HELOCs on my investment properties and interest rates were increasing.

It utilizes money sitting in your checking account to good use AND  you still have access to the HELOC, line of credit to pay off expenses and other costs.  

@Stefano Vrolijk it all depends on your credit history, whether you have an SSN/ ITIN and how much you can put down.

I do direct booking through the Houfy website, taking credit card payment by Square. 

I have never approved a tenant without meeting them, if everything looks good on paper, income, accounts, backgrounds.

DSCR loans are based off of down payment, credit score and either actual or market rents so it helps to supercharge an investor's real estate goals and net worth.

Why do you keep setting up accounts?

I used the background and credit checks offered through Cozy. 

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