What’s one of the best investments you can make in your home? If you’re a member of our target audience, you probably know the answer. As it turns out, Portland-based personal finance blogger J.D. Roth and his wife, Kris, (both college classmates of mine) know it as well, and yesterday, Kris shared a wealth of useful information about it on J.D.’s popular and well-regarded site, www.getrichslowly.org. Bravo, J.D. and Kris (and Go Bearcats!).
