I'm in Michigan as well and I think when I took the salespersons test there were 14 math questions.

To @Bryant Brislin point as well - you probably don't want to start anything without first confirming that this spot would be feasible for a national chain, or at least a local chain/restaurant that would be interested in the space. 

I own some property out there as well so happy to point you in the right direction.

I have seen some decent lots sizes as well to add in an ADU or Carriage Home/mother in law suite. 

More info is needed but, depending on how much you paid for your current home, buying a a new home and renting your current one may not work too well if the rent doesn't generate cash flow or at least cover the mortgage payment. 

If you’re buying in a desirable neighborhood and have the capital to do fantastic design and furnishing, you will still do very well.

I have a good W2 income as well as STR income. 2023 is the first year I thought I could qualify for RE status as I am working as the property manager, handyman... (750+ hours) man I worked hard!

We might as well have ΦΠΑ and evade it Greek-style.

And one room was about 10’x12’ and we still got a dresser and a comfortable chair in that room as well.

You can hire someone to pull local leads for you and you can outsource the direct mail as well.
