We also currently have an LLC set up for our short term rental operations which we have been already running out of our spare room in our home which will cease when we rent it out.

I found this in June and I have made a $7000 profit flipping 2 lots in my spare time.

I chose this larger apartment because I had initially planned to rent out the spare bed + bath for $700-800/mo, but he stopped me because he 'wanted to ensure our privacy.' 

Can I just convert the garage into an extra room and potentially rent it, just like I would with a spare room in our main house.

The initial plan was to slowly rent out the spare rooms and renovate until a refinance/moving out and onto the next property made financial sense. 

Even when you exclude the ones who are simply renting out their own spaces - second homes, pre-existing ADUs, spare bedrooms, or their RVs, the number of people that started with less than we have is likely still significant.

I don’t spare expense when it comes to the safety of my tenants and my property.

It’s such a small compact city the only area of concern is the south side.

We have spares to rotate them.

I'm not an attorney; I just read personal finance articles in my spare time.
