Not to be a contrarian, but I believe you are missing an important first step. Have you and your husband discussed this with your financial planner, CPA, and attorney? I would start with them, ask them to lay out your options and only then look for areas. There are calculators that will assist you in determining which properties might be a better investment (based upon returns from rent and taxes)
Will you and your husband also be physically managing these properties? or hiring a management company? Are you ready and able to deal with damages and evictions? If not, then rentiing, no matter how good an investment may not be for you. That's why I suggest speaking with professionals in other fields before viewing any properties. For any duties you are not willing to take on, expect returns on your investment to decrease (rapidly) no matter which city you choose for properties.
College towns have done well. Is that why you are chosing Mt. Pleasant? Since you are in Westland, maybe you would consider Ann Arbor as something closer, or do you want to retire in Mt. Pleasant?
Let me know if you would like me to introduce you to a Realtor in Mt. Pleasant.
