Can you finance a property after purchasing with cash?

[Karen Pendergast]

Hello! I own a rental property (townhome) that I paid cash for from an inheritance three years ago. The property is in an LLC, and I am the sole owner of the LLC (I'm married); property value about $300K at this point and it is continually rented. I would like to either mortgage the property or set up a HELOC on it to leverage my buying power for additional investment properties (down payments). My questions are: (1) is it possible to get a mortgage on a rental after having already purchased it? I ask because when I contacted Quicken loans in the past, they said they "couldn't make it work". I assume they couldn't offer a competitive rate and make money on the loan, but honestly, I'm not sure as I didn't pursue a detailed answer (I'm steadily employed in good career; my credit score is usually around high 700s-low 800s; have retirement accounts; and equity in my primary residence). (2) Is it possible to get a mortgage if the home is in a (single owner) LLC? (3) Would HELOC be more advantageous than mortgage? I'm thinking there are less fees and rates might be similar? (4) What snags/issues may be foreseen given it's in an LLC, if any? (5) What would you do? Goal is to acquire additional properties (buy and hold/appreciate). Thanks in advance!
