Can anyone recommend a good real estate agent in Joshua tree that has sold to STR investors and familiar with str market and zoning? 

location dictates a lot of RE wealthYup, that's right ;-)But about housing affordability, we are barking up the wrong tree.

Yucca Valley/Joshua Tree are very saturated with STR's. 

Hey everyone,I’m building out a short-term rental in the [Joshua Tree] market and looking to connect with local cohosts or STR operators who take pride in running top-tier guest experiences — the kind where systems are dialed in, and the property shines every time.I’m not looking for a traditional property management company  — I’m looking for a boots-on-the-ground partner who thinks like an investor and operates like an owner.I’m hoping to find or learn:Anyone here cohosting in the JT area and open to sharing their experience (what works, what doesn’t)?

Real estate is a long play, it’s like planting a tree.

You might want to try grading contractors based out of Joshua Tree.

Any tree-overhang risks?

Yes, those trees are on the neighbor's property. 

People love trees and boulders.  

This is all made worse by the fact that there's no "collaborator" login (as other solutions have).
