They can and do lash out occasionally. 

I’m still seeing SFR deals and even some duplexes in the $300-400k price range, and Multis occasionally pop up starting around $600k, although they rarely come up for sale.

There are some investors as members on here that are very busy that I work with buying properties on occasion.They are flying all over the country looking at properties to purchase etc.I only do deals in Georgia currently but they buy all over.So I would assume some are real busy doing deals and only glance at the site occasionally as that's all they have time for.Some are just readers more than posters.It's the way all forums work.

I do occasionally hear them downstairs, talking or music.

Seems to be mostly tourists looking for a T Shirt and outside of the occasional concert(We will actually be going to see Vanilla Ice there in July lol) there is just not much going on.

We've had interesting things go missing after a move out - toilet paper holders, sink stoppers, the wands from the vertical blinds, an occasional towel rack.

I see these occasionally, but most of the ones I've seen in the past year or so have been in the high teens. 

Let individuals move their own trailers in and pay the rent - except for an occasional screw up, most people who pay to move their trailer to your park and hook it up are never going to miss paying the rent.
