I am an Enrolled Agent and have prepared taxes in MI for 25 years.
First, if I understand your situation, (its a little confusing with all of the posts) You are going to buy a home here in MI and your husband is going to live elsewhere, and you want to file jointly. Please correct me if I have this wrong, but that is the premise I am going to use in answering your question
According to MI law, you may only have 1 principle residence (homestead) in the state of MI
at a time. This is because principle/homesteaded residences do not pay any school millage in their real estate taxes
If your Realtor is claiming more than 1 principle /homesteaded property, then either they must be living apart, or they are unaware of the 1 homestead rule
Please see page 17 ofMI-1040CR Instructions
MI is beginning to crack down on people who claim the homestead exemption on more than 1 property. We've been seeing that more & more lately.
As for your filing status, if you file joint for Federal , then you MUST file joint for MI (see page 3 of the above link under "Who must file a joint return.)
Now to TX. Since your home ceased to be either of your personal residence and you state that it is now being rented, this now falls into the category of "investment income" and is no longer eligible for the homestead exemption.
However, if your husband does not live in MI, and he purchases another home somewhere, then yes, you may homestead EACH property, but each of you must be able prove that the residence is their “principal residence”.
