When I replied back to their email asking when I could pickup keys to assess the situation, she doesn’t respond to email, nor she pick the phone, nor responds to text.

I've been taken advantage of financially of, 2 properties broken into, etc - being 2000 miles away is a huge negative. 

-Be able to turn your phone off because your voicemail lists an emergency contact for your on call plumber/hvac guy.

If you owned a property with a broken stairwell where someone trips and falls, got incapacitated for life, why would their damages be restricted to $170K.

Actually TALK TO THEM on the phone and/or in person, find out about their situation, and if they seem like a good fit, basically just be smart about it, and have human interactions with them, it's that simple. 

I would collect guest data for 1 year (phone and email) and then have a direct booking site and a marketing campaign to previous guests to book direct. 

Instead of SF I have it broken down per room. 

I can't post phone numbers here but you can find them with a quick google search. 

Broken blinds, refrigerator and freezer door left wide open and running.

@James McGovern, while I don't necessarily agree with your language, I certainly understand where you are coming from.If you truly want to exploit them, then continually report code violations: long grass, broken windows, broken down cars parked on property, anything that will keep racking up the nuisance issues of the property that the landlord not only has to handle with effort but also with money...But, assuming you don't want to go to that level, find the owner and reach out.
