It does appear that we need more information about actual ability to pay the rent but in reading between the lines it appears that there will be two more adults living in the property, so we have more information to gather.

I live in Utah, where the real estate market has exploded to say the least through COVID, so investing in my backyard isn't something I'm interested in right now.I'm looking for a market with houses available to be renovated under $50k!

By no means cheap but solid rent + demand, fun place to live, decent inventory (relatively speaking), and is still commutable to the city. 

Purchase price: $45,000 Sale price: $175,000 I lived here for a few years then when I was married it became a rental.

But the issue you will have to live with is the fact that you will have to disclose this.

On my lot where I live, I can have as many kitchens as I want (not sure why I would have extras) and can build a tower, but they won’t let me build an ADU for my mom unless it is connected to the main house.  

Consult eviction attorney regarding commercial; I'm specifically a residential PM and commercial usually has different rules because of the nature of the investment and occupancy (tenant doesn't [usually] live there)

A revocable living trust is another option for privacy and asset protection.Avoid gifting the property before death, as this would pass the original purchase price as the cost basis, creating a large capital gains tax liability upon sale.If the property is Subject A’s homestead, ensure the correct titling to maintain Florida’s homestead protection for Subject B.This post does not create a CPA-Client relationship.
