what can you improve in your application next year? Obviously the top schools that didn't interview you thought your application wasn't strong enough. I see three aspects you can marginally or drastically change.
1. GMAT: 720 isn't low but for international, it is low for the schools you mentioned. All the schools dinged you have average of 727~734, and that's average. You're below average and you're an international (usually they are higher than average)
2. Career: Any big promotion or meaningful work product by the end of summer?
3. Essays/Recommendations: These are very subjective, but do you think you can make them much better? This is where admission consultants would be helpful.
If you don't see any major improvement in those three areas, I'd take money at UCLA. IF you do see big improvements in 2-3 areas above, then I say it could be worth giving a shot.
However, given your career goal, I recommend go with UCLA $50K. RE development usually hires last minute as opening is available and also doesn't pay as well as other industries (banking/consulting). I generally recommend not pouring debt on you unless you want to go banking/consulting.
