I’m a full-time traveler. I use these 5 to spot red flags in any vacation rental listing.

• I’ve learned to spot red flags while booking a lot of vacation rentals online during my travels.
• Diving deep into reviews provides the opportunity to learn from previous guests.
• I’m skeptical of listings with photos that use wide-angle lenses to make spaces look bigger.

I’ve been traveling full-time for the past two years.

In that time, I’ve stayed in more than 40 unique rental units for a total of more than 380 nights across 16 countries. (The other nights were spent on cruises, hotels, or at friends’ houses.)

A never-ending vacation may sound relaxing but it means I’m always looking for my next accommodation and hoping it’s good.
