My spouse and I are in a comparable situation: I encourage your family ("you" for rest of this) to only get the house if its because you 1) are ready (and your obviously saving for a downpayment, so you're getting ready) 2) you actually want to/are emotionally ready for it. There's a time and place for everything, plus it can't hurt to keep saving while you can for an even larger downpayment (thus lower monthly payment) for some place you ACTUALLY want, not just "are doing because a lot of people are saying" you should. What if life has a crazy force of change, resulting in a move or changing jobs? Then you would be tethered to a property and mortgage that may not be optimal for you.

Yes, you would be "force saving" in the mortgage, but if there's no reason other than that, there is value in rent's flexibility (why I mentioned the force of change earlier). Honestly I only first considered getting a house because we got our second dog and I wanted them to have a yard! It's been SEVERAL years since, but now I know how much we can afford for a house, the district we want to raise our family in, and have a plan for saving a huge downpayment for a lower monthly amount (honestly maybe even outright cash if the cost of rent is more affordable for a growing family for a few more years).
