A few questions:
-What is your background industry?
-What's the deal with the current unemployment? What would be a realistic next job you could get right now?
A few thoughts:
-You seem fairly split on your post-MBA goal, I would think hard about MBB (I think you'll be competitive given your GMAT/Top 20 undergrad)
-Given tech as a second avenue, UCLA is great in tech
-Given your Cali desire long term, UCLA gets treated as a top 10 for sure on the west coast and you'll always have a strong network even if you target somewhere else immediately after school
-Data shows that GMAT scores drop with age, while there is no doubt you're capable of scoring well, consider the possibility of a drop to 710-740, in that case, I don't think your chances at an M7 improve at all
-Consider how likely you are to land a new job (and new letters of rec) that will move the admissions needle at all in 8-10 months
-The M7 vs. top ~16 distinction is not that big of a big gap, I suspect you'll find that many Anderson students also had interviews (or even admits) to higher ranked programs. Outside of H/S/W, money/location/industry/fit become more important.
The long/short of it: If you didn't have to retake and find new employment, I'd say go ahead and roll the dice once more. However, given that these are uncertain, and given your long term Cali goal, consider that UCLA likely won't re-admit you. This leaves just Haas (possible) and Stanford (unlikely) for your west coast tier one options. Is gambling for those worth passing up UCLA and getting a solid 2 year head start on your peers and financial goals?
I'd take the bird in hand.
