Hello all! My wife and I bought a house in 2020 during lockdown and scored a great interest rate at 2.85%. The house is in a perfect neighborhood with good schools and good neighbors. We’re about to welcome our third child and there just isn’t space for all of us in the house anymore. We’re nervous to buy a new house because house prices have skyrocketed and we would more than likely be tripling our mortgage to get a very slightly bigger home. We should be able to sell our home at a decent profit more than likely in the range of 100k+ to help offset the cost of a new home. We’re currently in a ranch and I’m not sure if it would be more cost effective to build up or to just buy a new house and sacrifice our interest rate. If anyone has any insight it would be greatly appreciated!

I welcome any suggestions!
