I currently live in it as my primary residence but had plans to eventually rent it out and then cash out refi once I reach 20% equity in the property.

FHA loans are designed for primary residences and require the borrower to be an individual, not a business entity.

(May also cut significantly into the current cash flow on it)I know you mentioned not doing a HELOC on my primary, but wouldn't it be advantageous to have the ability to pay off the line of credit instead of be stuck in a payment that is much higher? 

I've got about $525K in equity in the property, but lenders have told me that I cannot get a HELOC to access that equity for additional purchases because the duplex was financed as an investment - they have said TX law dictates that HELOC can only be used on primary residences.

Quote from @Brandon Croucier: That’s a killer loan if they are actually offering that.Seems extremely below market value as even primary mortgages are higher than this right now.I would beware of a bait & switch on this. 

Just a good person too if you want to bounce any ideas off her. 

It was my primary residence for two years before I turned it into an investment property.

Don't grill me too hard.I own three rental properties, one is my primary residence with an apartment (5 units total between 3 properties: 1 airbnb, 2 medium term healthcare leases, and 2 long-term rentals).

If you can get a better primary residential HELOC rate than you can a hard money bridge loan I would say yes.

Quote from @Mary Jay: Quote from @Jay Hurst: Quote from @Mary Jay: hi guys,so I have a lot of equity in one of my rentals but the interest rates are super low on it. so I dont want to do a cash out refinance on it because I dont want to lose the 3% interest rate on it.I want to get some cash out of it via Heloc or another vehicle,  so I could buy another rental, but its not my primary, so I cant get a HELOC on it from lots of banks....I think PenFed does helocs on rentals, but because I have more than 5 rentals, I dont qualify for their HELOC loan.IS there a bank that would give a HELOC/cash on a rental?
