I saw a property a month ago on zillow to rent and it was handled by this company. We liked the property and we wanted to rent. This company's agent told us to submit an application ($40) and we did. After that I did multiple attempts to get a confirmation but I was always told that the Landlord is out of country. In the last week they said they want paystubs and offer letter and other details and I provided that too. Despite of all this, when I enquired today, they just removed the add from Zillow saying they no longer are renting the property. I suspect this is a case of scam and unfortunately, Keller Williams could not confirm it. It has been a worst experience for me.
