@Ryan Stumbo no need to get defensive. I'm just simply stating that the arcadia area is one of the hottest sub markets in the metro therefore the price to rent is not going to be favorable for long term buy and hold investors. We own property here and out of state so I get the need to chase yield.
As @Jay Hinrichs stated previously, the FHA loan is only for owner occupants. It doesn't quite sound like you wanted to house hack, just a clarifying statement. If you wanted to go conventional with the investor loans, then your lowest down payment may be 20%. When you run your numbers with 20-25% down are you still negative?
Leverage and time are your best friends starting out. I highly encourage using debt in the current low interest rate enviroment, just got to be sure you are using the right type of debt when running your numbers.
As a landlord in the valley, the rent growth is no joke, rent has almost doubled in the last 6 years with no slowing down I'm afraid. There will be an affordability issue in the working class neighborhoods, but in white collar neighborhoods the rents will continue to soar.
If you wanted to spread your 150K across multiple properties you may only 1-2 in the Phoenix metro as the average purchase price for SF is over 300K and 25% down is 75K.
Just trying to provide some insight, not rain on your parade.
Best of luck
