FHA just extended the big changes they are making in the condo approval process until Nov 1st. You might want to call the HOA mgmt company and ask them a few questions first to see if it's worth your time to pursue. FHA spot will require (among other things):
-51% owner occupancy
-no one owner can own more than 10% of the units
-adequate reserves
-90% of the units sold
-no legal action pending
-no pending special assessments

Even though they extended the deadline, not all lenders are still doing spots.

I am Doing an FHA spot approval right now in Tampa. Better hurry up and get approved because FHA is discontinuing FHA spot approvals come OCT. 1st. As a matter of fact you might already be out of luck.
Sorry.
