We are planning on using our VA loans to buy duplexes as our initial investment.

Is the process for applying for refinancing different from applying for a mortgage to initially buy a property?

I initially looked at this deal in late January 2020 and had it under contract prior to the pandemic.

From my understanding ROI is initial investment/net income x 100. 

I'm impressed by your initiative and drive.

Also understand that those proposing these measures have clearly indicated that these initiatives represent merely a first step in their long-term plans to effect the single largest wealth grab in the state's history.

Now that I've been looking through BP, listening to the podcasts, and reading some other books like "Richest Man in Babylon" and "Rich Dad, Poor Dad", I have some initial goals for my real estate investing.(1) I want to buy a home for me to live in. 

Our initial investment was around $20k.

What is best option to fund: 30yr 400K fixed rate loan with about 4% interest (250K reno and 150k to make payments until we get renters) or HELOC still 400k but with floating interest initially about 3% (10draw/20pay) Thoughts?

If renting, you will need to see if the property will cash flow once financed (assuming you are looking to finance this once built, which would be max 75% LTV for a 2 unit property (max 70% LTV if you cash out).As for financing, I think that may be tricky, since you would be initially distroying value as you demo the original house.
