You can, do you intend to occupy the SFR is that why?

Make sure the future FHA loan you want to originate is on a home you plan to occupy as your primary residence.If you run into any trouble doing this please reach out to me.  

Live in for a year, then move and rent out the unit you were occupying. 

I believe the threshold is you just need to occupy for 14 days a years or around that. 

This assumes the market rent for the unit I will be moving into.My goals from entering real estate are 1. add diversification in my investments (right now heavily invested in stocks) and 2. house hack, so that tenants pay part of the mortgageIn my current market, I have two options: a. buy older houses, renovate, bring the rent to market --> this will cashflow, but needs a lot of time investment which I don't haveb. buy turnkey properties: --> renovated and already occupied by tenants but may not be cash flow positive.I found a property that's type B.

Usually, we want to occupy while stationed state side...but if we are on TAD it would be impossible for us to occupy that property...and the VA loan is understandable about that. 

Occupants: The Tenant shall not allow or permit the Premises to be occupied or used as a residence by any person otherThan Tenant and the Permitted Occupants.

If I were in your position, I'd go the 5% down conventional route that Fannie Mae recently introduces for owner occupied 2-4 unit properties.

Regarding commercial lending they are usually less interested in you, and more so on the property itself, unlike residential owner occupied “conventional home loans.”They will look mostly at DSCR, and LTV.

Some lenders won't allow it, but there are lenders that do. it is a business purpose loan - you'll need to sign a form stating that you won't be occupying the property and your rate may be slightly higher than if you were to close in an LLC.
