Efficient Rental Portfolio Strategy?

[Joe Fornasiero]

I'm looking for input on a strategy I've been considering. I've owned my current home for 2 years and house hack with 2 roommates so my entire housing expense is covered at this point. I'd like to rent out my current home and purchase another one. I would bring the current roommates with me to cover the cost of the next home. Doing so would allow me to build up my cash reserves quickly in between purchases. I'd plan to stay in the home for 12 months and then repeat the process. I have someone that wants to partner/invest with me and will help to cover a portion of the down payments and maintenance on the homes. My thought is that I could leverage the lower down payment (5% conventional or FHA) and interest rate on the loan which would allow me to obtain greater returns on the cash invested. Does this seem like a feasible option? Are there any other options that may be better to build a portfolio quickly? I know @Elizabeth Colegrove has used a similar strategy with success from the reading I've done on the forums. 

Details on current home that I plan to rent out. The home is fully renovated will all new appliances so maintenance and capex should be minimal.
