Applicants are in mid- to late 20s. 

If you want to do a background check and lease for Airbnb bookings, you have to put it in the house rules so you have the guest agree to do it after confirming the booking on Airbnb.We don't do mid stay cleanings, but we do expect a deeper clean after all our MTR stays.

In this case, you might want to mix it up and be partially a mid-term and short-term rental.

Lastly, in areas that are seasonal, operators can consider mid term rental (MTR) for the off season period at a significantly reduced average daily rate.

This county has big universities, colleges, and hospitals, and has cash flow for long-term/ mid-term rentals.

So you've never seen a 40-something man inherit a good chunk of change, promptly have his mid-life crisis, and squander his inheritance and what little he had?

You'll need to start now(mid 20s) and wait until probably mid 50s to get to really living off passive income.
