I was very impressed with ISIS both from a sales and lettings perspective. As a landlord I need an honest opinion on how my flat will perform and what I need to improve to ensure tenant retention, I got this from ISIS.
I also noticed ISIS worked hard for both parties ensuring I had the necessary checks in place and the potential tenants had theirs.
Finally, they always kept me up-to-date either by phone or Email and when the offers came in they did not encourage me to jump but waited until I considered the tenants ideal. Overall process was slick, easy and thorough.
