is it better to buy down or refinance if wanting to ove in 2 years or so ...

If I read your question correctly you are asking about refi now or buy down the loan if you are going to move in 2 years. You need to do the math to see how it shakes out for you and you have to be sure about the move in two years. You don't say how old the current loan is or what the rate is, if it's old you are paying more in principal than you will if you refi. Most refi's break even in about 5 years, so if you refi'd now the cost of it would be breaking even in 5 years. If you move in 2 you will have spent more to do the refi than it saved you, but the lower payments for 2 years might be important to you. If you pay down the loan for 2 years you will end up with more equity when you sell, but your payments for 2 years will not go down. If you are sure, really sure about moving in 2 years I would say not to refi and to make the regular payments and save the extra money you would use to buy down the loan or increase your monthly payments and use the extra equity later.
