From my understanding, if you owe more than 80% of the home's value, you must have PMI.

Unless you split the loan up in a 80/20 or something of the sort.

My wife and I closed on our house about 3 months ago and got money back at closing. $0 down, $0 closing costs + money back.

Be careful with brokers, though. Some will try to spring some last minute crap on you and force you into a crappy deal.

You've got plenty of time so don't rush it. Go into your local bank and ask questions. That's what they are there for.
