The problem is the over saturation of them.  

Saturation is definitely upon us but quality product continues to get booked just like other markets.

There are opportunities out there but some strategies are risky. 1 - Airbnb (STR) comes to mind - very competitive, very saturated and becoming highly regulated.2 - Most STRs are transitioning to MTR so that market will be saturated soon if it isn't already.3 - Insurance crisis in florida is getting bad so those costs will eat up cashflow and short term appreciation.

@Trevor McCormick I would say that it is an okay market but is very saturated and alot of investors are having a tough time right now.

Sure, it is saturated, but you just need to find the right deal.That said, I love the northeast! 

Is Denver over-saturated for mid-term rentals or is there still demand?

I'm also seeing lots of homes for sale that were used as Airbnbs, so I'm wondering if that along with these numbers may indicate it's an overly saturated market, and if these are signs that maybe I should keep searching for a stronger market, or just a property that cash flows given the average annual revenue?

Hey @Jonathan Sanchez, a lot will depend on your area.If you are buying in a saturated area with lots of competition, then using an aggregator like Pricelabs to help make your pricing accurate is handy.If you are in an area that has less, then simply looking at nearby properties that are similar to yours on VRBO and AirBNB.

So far I have been seeing the markets saturated with agents and investors.

And IMHO, the prices are dropping big time (on avg. 10K/month...houses that were above 300K a year ago are not selling at 250K now) and the available rentals saturation is worse than I seen during summer season (with rents dropping from 1$-1.08/sqft to 0.8$/sqft and very little contacts and applications...just go in Zillow and look how many rentals are on the market now in Kyle, New Braunfels or Converse).
