A method I would recommend would be purchase a FHA 2-4 unit Loan at 3.5% down for your first and live there for a minimum of 1 year. After the FHA the best option I think would be a VA 2-4 unit and live there for a minimum of 1 year. Now you have 3 homes that should be cash flowing and you can refinance your FHA to a Conventional as at this point you should've reached 80% LTV which frees up you FHA for use once again. If you did all that you will have 3 cash flowing properties and should be able to bypass the House hack method and start buying investment properties.
Another option is using the VA a second time and this gets a little sticky if you are buying and holding. After your first use you will have a remaining amount of eligibility for use that will depend on the amount of your first loan and the County loan limits that you are looking to purchase in. Anything over your remaining eligibility you will have to put down 25%. There is another option to reusing your eligibility if its all used up and that is a One time Restoration. This is one time deal and is only usable once in a lifetime. You will refinance out of a VA, use you One Time Restoration and it will renew your eligibility allowing you to buy another VA 1-4 unit for 0 down and killer VA rates.
There are many routes to success in real estate and it all depends on how you choose to play
Best of Luck!
