> Originally, my plan was to use it for a house down-payment, but with the mortgage rates having nearly doubled in the last 6 months, that's kind of out of the question at this point (especially having moved to a higher property value area to be closer to friends and family).

Higher interest rates lead to lower home prices, which should make it easier to make a down payment. Interest rates may double, but mortgage payment amounts typically end up staying the same. You are in a prime position to buy a house. In the next 30 years, mortgage rates will likely decrease and you can refinance to a better rate, and end up paying a lower price for your house than what you would have had mortgage rates stayed low.
