i found a house for rent on zillow, but the contact info for the home is incorrect. what now?

I'm assuming you mean that the phone number is incorrect. You can also contact them by email if you fill out the contact form in the upper right of the listing page and click the blue "Contact Property Manager" button - Zillow will send them an email and let them know you're interested. If you want them to call you back, give your telephone number in the email contact.

Be wary of scams - Scammers often use fake phone numbers so that they can keep the conversation over email. If they reply back and tell you they're out of the country, report the listing by clicking "edit->report problem with listing".

thanks for using Zillow,
