However, a judgment saying a tenant owes rent is not sufficient to evict them under City protections.

Your screening process is not sufficient, ask all the right questions.

You stacked at least 5 things.203k purchase in the bay area.Contractor working for free in the bay area.FHA on a multifam, hoping it passes the self sufficiency test, in the bay area.Somehow sneak borrowed funds into the transaction without the underwriter knowing. 

3) Do you have a sufficient buyers list? 

The quarterly calculation to begin on the first day ofthe month following the completion of the first quarter after the purchase of the first Property, to be paid to the extent that(i) the Company has sufficient Net Distributable Cash to pay such Preferred Return, and (ii) the Manager elects, in its solediscretion, to make such payment or defer such payment to a later date.

Like Russell said, be cognizant of the self-sufficiency test for 3-4 units using FHA. 75% of your rental income must cover PITI (principal, interest, taxes, and insurance).

With the purchase of a house, transfer of addresses to Florida, and intent to move permanently in the near future, would that be sufficient enough to establish residency? 

@Rachel Hertel - Regarding potentially "not" qualifying, you need to understand FHA's "Self Sustainability" or "Self Sufficiency" test.

If they do not pay rent, and their security deposit isn't sufficient to cover what they owe (in rent or in repairs), they will then have a negative balance on their deposit reconciliation you send them within 14 days of them moving out.

Adios self sufficiency test!
