Our STR/MTR portfolio typically sees around 80% occupancy, and I’ve noticed that the online travel booking sites often push properties with consistently great guest experiences.

Are you looking to flip or for long term?

True, but (a) they were typically experienced investors, and (b) today's market includes record prices and high mortgage rates, which is a double whammy. 

If you do decide to start flipping homes- as a new investor you can either self finance with all cash, or you can contact a commercial lender like myself and expect terms to be 75-80% of the purchase price with 100% of the rehab financed through a draw.

This is typically for most people not a DIY project. 

Yeah, I keep hearing that Furnished Finder is the go-to place for mid-term.

You can offset other passive income of gains with depreciation from your long-term rental.  

I've done it twice in Reno, NV (now I have them both as long term rentals), and it's changed my life. 

I tend to shy away from homes over ~20 years old to buy and hold for long term renting.

For Short term renters ?
