As @Julia Lyrberg noted, MTRs typically rent for more than LTRs, as they should for a furnished home with utilities included. 

furnished rentals are going to be the ticket here for a while.Also keep in mind and I think this is pretty important as well.  

Or at best you overpay and the "designer" buys the cheapest junk furnishings possible. 

I was able to replenish emergency fund money I had to dip into for furnishing, was able to pay off a hot tub, was able to replace 2 garage doors and paid for a larger repair this year.

Hi Randall-Congratulations on buying a rental property well back in 2020.I am sorry to hear the property is now cashflow negative $200 a month.Your question is should you sell or continue to keep it with the negative cashflow.Depends on your personal goals and if being negative $200 a month plus any unexpected repairs or vacancies is affordable to you, but if you can solve the negative cashflow by turning the property into a furnished mid-term rental, for example, your future self may thank you.To Your Success!

We still owe roughly $900K on a 3% mortgage.We’re planning to retire abroad and are weighing two options:1.Sell the home – I already have a buyer lined up, so this would be a straightforward exit.2.Rent it out long-term (furnished) – While I don’t think the rent will fully cover the mortgage, it might come close.

Airbnb and Furnished Finder has been our go-to in the Denver market.

Every where you turn there are STRs going up on the market fully furnished because they couldn't pay the mortgage and bills with the rental income. 

It really isn't investing but creating a job for yourself.Don't forget you will need between 10k and 25k for setup and furnishings if you are able to find someone who will allow arbitrage with their place. 

To do Airbnb, you would have to furnish to the nines and add tons of amenities so it is group accessible.
