So to help cover expenses and see some cash flow would focus on multi-unit property. 

Use a reputable expert like @Dave Foster and you’ll be covered.

One thing I'm trying to do is to test different cover photos to see which ones draw a greater % of click-thrus (which seems like a reasonable thing to test).I'd like to be able to view the Airbnb stats to see, for each cover photo I test, things like what % of people click through on it.

Are you trying to afford a house much more expensive than your W2s could cover? 

Hi Owen- Most others have covered the specific areas to consider.

What period of time does it cover?

If we wait and buy in 26 she would move in and let others rent with her and hopefully cover the mortgage. rent is super expensive there!.

However, vacancy means covering 100% of the expenses.Multifamily properties almost always generate higher cash flow due to multiple income streams, which also reduces the risk of vacancies.

Morby says something in his groups that isn’t covered here.

If it's a gray area, we usually cover the service call the first time.
