Hi Trent, seems like this will make a good property for you in the future.
I struggle with the same thing all the time. I have a tenant now that has been in my building for four years (I inherited his lease) but he his paying below market rates. I have gone the route of getting the people out that didn't meet my personal minimum qualifications and then I renovate those units and get new people in them. I want to keep the people that I know will pay each month to minimize my expenses during the turnover. Then over time, I would try to raise the rent around the best time that allows you to easily rent the place if they walk away. For example, I would tell them I am going to offer a new lease in June (this allows you to tweak the lease if you don't like specific things) and at this time bump the rent. Maybe not 150 per month all at once, but at least something. If she tells you that she can't afford that and wants to go somewhere else, you can easily clean and renovate the unit before august which is the best rental month around Lansing.
Also, just some advice on your numbers. Depending on the age of the building, you should bump up CapEx and vacancy to 10%. In a house hack, you really only have one unit which may sit vacant for some time.... For CapEx, I use a higher number because you will want to use legit contractors on your business for liability reasons. Good luck!
