I have started using Chiltern Hill over the past few years to rent my property.
I must say, that to begin with, it was quite a headache, as whenever student tenants left, the house was left in quite a state, deposits dont always cover the extensive damage done by inconsiderate students.
However, having asked them to change my properties to non student living, i have been quite impressed. Rent is always on time, and most importantly the houses are left in good condition with no need to retain deposits and revamp the entire house every 9 months!
Quite happy with the service all in all, not much more i could ask of them.
