• Your home: Try Airbnb.com and homeaway.com.
What you can make: About $60 per night for a private room in a house (minus a small commission or service fee for the site). You don’t have to live in a vacation hot spot; popular properties include those in small towns.
Be aware: You might need to charge less than Airbnb’s suggested rate until you build up a base of positive reviews.
• Your car: Try relayrides.com.
What you can make: Up to $1,000 a month. Cities and college towns where not everyone owns a car are popular.
Be aware: Consult your insurance policy first; some policies prohibit renting and might not cover you in an accident.
• Anything else: Try Zilok.com, snapgoods.com and rentabilities.com.
What you can make: $15 to $25 per day for most items. Keep the season in mind (snowblower in winter, for example).
Be aware: The sites deduct a 5 percent to 7 percent commission on your profits.
