User Testimonials

"I live in a vacation community that limits short-term rentals. Halo Sentry lets me monitor for loud gatherings which keeps my neighbors happy and keeps my business secure"

"Promoting my property as no smoking property helps drive occupancy higher, and Halo helps secure verification. Also, Halo can lower costs through proactive mitigation because every time a guest causes damage, I need to pay for damages and can't rent out that unit for a period of time, so lower occupancy”
