Home sharing websites like airbnb.com are great for getting the most out of your vacation. Home sharing often saves a lot of money compared to similar lodging arrangements at hotels, and it gives you an opportunity to be part of a new neighborhood during your stay.

The downside is that there’s a bigger chance of encountering a scam. No one wants to have their vacation ruined by a fake rental listing, so here are a few easy tips to avoid scams.

Be skeptical of photos: If a property’s photos look a little too good, ask for additional photos. Photoshop and photography expertise can hide a lot of warts.

Only book with a credit card: Scammers prefer to operate with cash. You have a better chance of recovering your money if you only book with credit cards through trusted sites like airbnb.com.

Read the reviews: Sites like AirBNB and VRBO have customer reviews for each property. Read them to ensure that the rental is as good it seems—or that it even exists in the first place.
