One such user is Silvana Clark, a speaker and author “based” (loosely) in Seattle, who primarily uses with her husband. She has house-sat in a variety of destinations, like Spain, Portugal, France, Germany, England (that was two months in a six-bedroom manor house), Switzerland and Australia.

Her most recent stint was three weeks in a luxury Paris apartment, where she took care of a little dog and was able to use the owner’s car. Closer to home, she and her husband found a one-month house-sit near D.C. to spend time with their daughter without booking a hotel.

Wondering how you can get started? Check out the options on all three sites before you make your decision. Afterward, you can sign up for email alerts to be notified about new opportunities and search house-sits in the areas you’re interested in traveling. Some sites tell you how many people have applied for a certain house-sit — on it’s often 10 people or less, says Clark.

When you create your profile, choose a professional, friendly-looking photo, double-check your spelling and grammar, detail any work or house-sitting experience and include all experience with pets, says Kathy Robinson, who’s based in England and has hired about 27 house-sitters so far through

Try giving it a read from a homeowner’s point of view, and see if there’s anything you would change or add to make yourself a more desirable candidate. (Clark usually includes the fact that her husband has experience managing apartments, so he can fix broken garbage disposals or other issues in a professional manner.)

The application process is brief but usually involves sending the homeowner a little blurb about yourself by way of introduction. Make it professional but friendly, and just like when applying for a job, reference specific sections of the post and capitalize on anything you have in common.

And once you get the job? While you’re house-sitting, consider renting out your apartment or house on Airbnb or, if you’ll be out of your own house long-term, having a renter sign a six-month or year-long lease. That way, you’ll be making money and saving on utilities.

And make sure you leave the house you sit for clean in order to get a good rating — that’ll impact how attractive your profile is to others who might want you to stay in their abodes.
