My wife and I are in the planning stages of a garage project that will net us an apartment to reduce our living expenses when we move in and rent out our home. Not accounting for returns, we can save the funds needed in about two and half years. We're currently trying to figure out where to put this money (the account and fund type). We want something low risk, but with higher returns than a savings account, and tax implications are important. We're considering using three Roth IRAs for this and withdrawing the base to complete the project, leaving the gains in the accounts when we do so. What would you recommend we do with the money?
