This site is to a company that advertises that they will "buy your home for cash" (I googled it; did NOT go to the site) I too received this text after posting on Craig's list here in The DC area.
I got the exact same text as well. I listed my house on Craigs List in Quad City area of Iowa. I replied to the text as another person did about just calling on the house and haven't heard anything back. I also checked on the number. I got the same answers as other people did. The number is from Cleveland OH and you can pay for a name and other info. Has to be a scam.
