and why the broker only list this particular property on loopnet, while other listing was on multiple site?

Probably not that much.Neither you nor I have a crystal ball to see where the economy is headed and what will cause the next downturn, but I'd be willing to bet that when it does happen, the self reinforcing cycle of job lose you mentioned will happen, because the financial market is made up of humans who make sub optimal decisions with incomplete information. 

Then check their reviews on all of the sites and their transaction history on Zillow.

BTW, I used a elderly neighbor keeping an eye on a triplex for some small compensation, and over the long run, things that he notices because he's on site that I can't would save on fines, lawsuits over slips and falls etc.

Seller financing will probably be your best bet

This site and you guys are freaking amazing!

I'll bet 99% would agree with rounding up as a no brainer, effortless way to avoid unintended delays.     

I’m a Los Angeles based landscape architect working on creating some small site improvements on a property in 29 Palms just near the Joshua Tree Park.

I would also check your comps in rent say go back over the last 5 years and I would bet you are seeing over time increases to your rent in your area due to growth?

I am willing to bet that a house of that size with a Koi pond is in a fairly nice area that’s zoned residential, single-family.
