I did a typical 30 year conventional mortgage putting 20% down. 

Also how high is the interest rate compared to conventional home loan?

Are you saying to simply get a conventional loan... and do what with it?

My RE goal right now is to have 10 doors by 2030; acquiring approximately 1 door per year with CF of at least $100 in a BRRRR setting and between $200-$300 in conventional purchase.

I've always thought that I can use the VA loan and also use a different type of loan such as conventional for my rental properties that I'm not going to be living in because I already used a VA loan for my current primary property that I'm house hacking but I want more.

In contrast, if you buy a condo you'll have just 1 unit and your cash-on-cash return will almost certainly be lower.If you do go with a FHA, you are going to want to refinance to a conventional mortgage at some point (as soon as you can) to get rid if the PMI and improve your monthly cash flow.

It appears as if the down payment for a conventional, 30 yr loan, has to come from personal finances (Money in the bank with proof of earning).

As I understand it, for a house hack you usually as low a down payment as possible, which I *think* is in the 5% range on a conventional since this is not your first time buying a house.

These loans do not carry the same terms as a conventional loan.
