And presumably if you're on Bigger Pockets and talking financial stuff, you'll hopefully be in a position to pass wealth onto your kids. 

It sounds like you’ve built a strong foundation with your first rental—locking in a 2.25% interest rate and pulling in $4,500 in rent is a great position to be in.

If you plan to use the remaining HELOC for a DSCR or BRRR strategy, that could help you build more equity, but consider if the current market conditions will lead to higher rates and lower cash flow in the near term.If your goal is to scale, you might consider holding onto your current duplex for the cash flow and focusing on the BRRR/DSCR strategy, which can allow for more control and potentially better long-term returns.

Good cash flow and equity upon completion.

Some may tell you that you can systematize anything, but the problem is, every individual home is different (even the newer cookie cutter neighborhoods).Focus on two or three neighborhoods and know what a good deal looks like in those pockets.I would also temper your expectations as far as finding a lot of equity on MLS.  

I received a positive response from them today.

We pride ourselves in keeping the forums positive, helpful, and focused on real estate (please, no politics, religion, etc.).

With that amount of equity and being in CA I think you have a couple decent options1.

Hopefully things continue to progress, and you come out on top with a huge equity position/high cash flow when it's all completed. 

This is the structure we were looking at which is more of a subsidiary structure and this applies to raw land development: 📌 Structuring Plan1️⃣ Set up a QOF to raise capital from investors.2️⃣ Create a QOZB to handle hotel & parking development (each separate land parcels).3️⃣ QOF owns the land & funds QOZB for development.4️⃣ Raise capital through QOF equity, bank loans, or JV partners.5️⃣ Develop the projects & operate for 10+ years for tax-free gains.
