Over the last few weeks we've seen the 5 year fixed term mortgage rate move upwards from below 4% all the way to 4.29%. Granted, this is still a great deal, but it is going to cost a little more buy a home. Combined with recent increases in home prices, you may want to consider acting sooner rather than later!
If you are already are pre-approved by your lender they generally will hold the rate for you for a fixed period of time. You may want to check when your current quote expires so you don't miss out!
