New to investing-first business plan

[Emily Lange]

First off thanks for reading!

Im a very new investor and after reading/listening and doing some research this is my House hacking plan:

•Buy a 3db/2ba single family in Greenville SC as a live in. Possible small renovation work out of pocket, depending On the deal.
•VA loan, 0%down, pay closing costs w/cash. Which leaves cash in our pocket for unforeseen expenses.
• Rent rooms/air bnb to live for free or very little. Save like crazy-husbands on deployment. 

•use our own money for 20% down on the next deal, most likely multi family 

•use cash flow from second property toward first property to pay off ASAP. 
•repeat/unless I decide To go another route at this point

Any big flaws to this plan? Has anyone done this before? Any insight is appreciated!
