I rented Matt's place in the middle of a MAJOR snowstorm in Austin. I confirmed with him that his place had power and my family was needing a warm place with power and water. Matt rented the place out to me promising an early check in. But also told the family that was already there that they could have a late check out (they are from Louisiana, now stranded in Austin). It created a very uncomfortable situation in the middle of unsafe weather conditions. All the while, he wouldn't answer his phone and left it to us (both sets of renters) to create a plan for everyone's shelter and safety, sending a note: "I'm on a conference call. Can you please knock on the door and talk to the guests there." He left it to the renters to figure out safety, shelter, check-in/out time, etc. It was a nightmare. Matt didn't pick up the phone until the pipes at the home burst and he needed us to turn off the water main, hire a plumber and get it sorted.
Additionally, because of the duplex situation at the location and the weather conditions, Matt gave me the other unit's door lock code to go and check on the pipes there. When I entered the home (assuming it was not rented) I found personal belongings. It wasn't until later I found out that the unit had been rented to a long term tenant who also had the code to my rental unit / side. HUGE security issues. Luckily, all renters involved were more safety-minded and caring than Matt and we all banded together to figure out the situation.
