Is it because people that operate and manage their own str can hit the 100 hour participation rule?

Including financing strategies and cost of operating.

By accelerating your depreciation schedules, you reduce your taxable income which in turn increases your operating cash flow.

I am semi retired at age 44, I sold my franchise business 1 year ago and have a very good idea of what it takes to operate a business successfully. 

We are not real estate licensed, so that would be the biggest area of opportunity to learn (we'd use a realtor at least in the beginning).We are considering selling the company because 1) my husband hates managing W2 employees/operations (but he loves working with subs) and 2) it would give us extra cash up front to reinvest.

You know, operate it like a business.  

Some loans like DSCR (Debt Service Coverage Ratio) loans are based on how the property operates as a rental (income, expenses, etc). 4.

Yes, it's more work up front, but we have an investor relations team dedicated to performing that work so it doesn't distract us from operations. 

I want to be happy and free in my late twenties, like the book suggests, not worrying about operating these franchises.

For example, do landlords in that neighborhood charge for coin operated laundry, or do they hold pet deposits?
