Who knows answers to these questions:

1. How long do I need to wait to qualify for a FHA financing?
2. Can we buy 2-4 units with FHA financing?
3. If I am a renter in a home more than 50 miles from a 2-4 unit property I buy and I live there during the workweek, does that still qualify as owner occupied?
4. How much money do I need to invest outside of California and cash flow positive?
5. What strategies do you recommend?
