Buying a house right now or later

Me and my wife were thinking about buying a house for quite some time. We saved around 35k and not sure what to do right now with this economic situation. We see that in the past years mortgage rates were going down. But now with Iran the gas prices went up and probably mortgage also would go up. So we don't know what to do... should we try getting a mortgage for any house with this rate before it went up? Or wait more? Maybe real estate prices would go down?
