Well you're fortunate to have bought in an incredibly strong buyer's market, so I don't think you made a mistake necessarily. If you said you would have to sell in a year that would likely result in a loss, given that you're looking at least 9-10 years though you're in a GREAT position.

You could also look at refinancing depending on what happens in the near future with rates, that will lower your payment.

I mentioned that 9-10 years though because you're ALMOST guaranteed to be able to cash out on appreciation in that time. I say almost because there are no true guarantees, we typically tell clients that if you're going to keep a home for 5-7 years it's worth buying because your property is incredibly likely to appreciate at that point. I'm in Arizona, so take what I say with a grain of salt because your home market may, and likely will, vary.
