<human>: Can you condense the text into a few key points?

Long read, please bear with me: A still-recent house purchase (late 2013) ate up most of my emergency fund, which I've been working hard on rebuilding (I'd rather not debate the rationale behind the house purchase - it wasn't my first choice, but it was the best option available at the time and with a little luck and some trimming of other expenses, I'm confident it  will work out for the best). In any case, I bought the house late enough in the year that I basically got nothing back in terms of 2013 mortgage deductions. My accountant says I should get thousands back next year as opposed to paying thousands this year.

I'm a fan of /r/churning and have tried to make the best of buying and furnishing the house by accumulating hundreds of thousands of points/miles worth thousands of dollars (with maybe one accidental exception, I pay off my balances in full at the end of the month).  

Unfortunately, I just got hammered by a series of unavoidable major expenditures, including six months of property taxes. I could have paid in cash and been fine, but I opted for one last bit of churning using a new AAdvantage card (I don't intend to get any more cards for a long time, if ever). 

Obviously, I still have the cash to pay off the balance from the recent payment I'm considering a 0% 12-month balance transfer from the AAdvantage Card to a Barclay's Arrival Card that I never use anymore. I've never done a balance transfer before and am wary, but on its face it seems to make sense here. Is this a reasonable approach? Am I missing anything?
<bot>: Trying to rebuild emergency fund, can either pay off a sizeable credit card bill in full or do a 0% balance transfer, deal with the payments in a year and keep those funds liquid and continue re-building the emergency fund.
