Where to Park Proceeds from House Sale for 2-5 Years?
Your objectives are contradictory and/or not possible. Eliminating the non-taxable objective: You could divide the $100K in 5 increments, making a "CD ladder" $25K in 3mo CD (or savings a/c) $25K in 6 mo CD $25K in 9mo CD $25K in 1 yr CD or similar structure (6mo also works well) Every maturing CD you are able to access cash and/or invest in another longest maturity CD, and earn a higher rate of interest. This plan also works well to plan for future interest rates hikes. If you are forced to access (sell CD's)  ALL the $$$ at any time, you will only lose accrued interest, none of the principal.  All FDIC guaranteed. If non-taxable is the highest priority, "invest" in a tax-free money market fund....see Vanguard Funds. You will not have FDIC guarantee.
