I think these areas good to target.

Rob Willis,I contacted(via web page) Renters Warehouse because they said they would do a free valuation of my rental.That prompted a non-stop barrage of emails and phone calls wanting me to use their servicesand at no point did they bring up helping with the free evaluation of my rentals value.
