I really only hear mixed reviews, but can't say one way or another personally. 

As with many here, I've been using a mix of Cozy (now Apartments.com), Stessa, and a few other custom workflows for turnovers that have worked well in the past, but with the takeover of Cozy by Apartments.com I'm now out shopping for better options for my primary, tenant-facing service. 

My wife and I self manage a mix of short, mid, and long term rentals.

Yes, there is a bit of Tony Robins motivation mixed in.  

In markets like Phoenix, you might find a mix of both, but it’s always better to invest with clarity.Have you looked into whether the builder is still selling homes in the same community?

I'm coming from smaller scale mixed use development and fundraising.

It’s an area filled with short-term rental properties owned by a mix of out-of-town hosts and locals, but I know the advice here can apply to hosts and managers across the country!

Most of the ones failing have been due to lack of appropriate financing or inappropriate product mix.  

I have a mixed bag of renters: some use no assistance, some are section 8 and some are non section 8 but have used some housing program assistance (such as deposit + 1st month of rent).

A good mix of LTR'S is a very good idea so that all your eggs aren't in the STR basket.I like tourist destinations where STR'S are heavily ingrained and almost impossible to ban or regulate out of existence.
