I think your main issue is your indecisiveness. If you want a lovely bigger and better located house, you have the resources for it, so go for it. If you think you just want it because we are conditioned to upgrade and because you can afford it, pick something else to spend your surplus on and enjoy that. But hoarding money away for the what if is not giving anyone in your family any value. Worst of both worlds is a smaller house than you would like and no enjoyment from your hard work and savings. The sooner you decide what to do the sooner you can enjoy it!
