Additionally, I’ve secured seller financing for half of the purchase price, but I’ve been told this could complicate things further since banks typically prefer being in the first lien position.

You have a niche, those happy to leap over dollars to snag those pennies, and that's a-ok, bravo for you, seriously.

If the former PMC had specific vendor agreements, confirm their terms and see if they can continue under your management, or transition to your preferred vendors.

Lastly, take a lot of time to learn about different financing strategies for your specific niche and learn how to analyze deals and run numbers. 

I prefer to tap into the equity using a HELOC I’m just unsure about the best way to grow and scale from there.
