My assumption is laundromat clients tend to be on the lower income range.  

Long-term investment should cover income shortfalls and consider alternative markets outside San Francisco or affordable markets like Texas, Ohio, or Arizona.

However, if I earn too much “earned income,” I risk losing these essential benefits.That’s why I’m exploring real estate and the stock market, as these generate “unearned income” and allow me to maintain my benefits while building financial security.

I've read a few guides about turning the main on gradually, going fixture to fixture one at a time, etc.

Quote from @Carlos Lopes: Gross income doesn't matter.This is the number most people post, and it's 92.7% useless.What you need is NET income, meaning the money left over after all expenses, and that should include a dollar amount for your personal time spent operating the business. 

I've got my long term goal....retirment income in 10-15 years figured out, identified and traveled to a few markets I think could work. 

Having bad tenants is not something you would like to have, thus make sure the tenant has sufficient income, credit, and who they are.

Option A (continue renting) offers stable, inflation-protected income and potential appreciation, but managing the property may impact your retirement comfort.

They also get financial help from the city since they help to see low income patients.

So i have pretty sizable personal assets, along with a relative high income.
