I used Northwood to act as Letting Agent for my property when I went to work overseas. I took up their Guaranteed Income option as I did not want to have to deal with any hassles with the property whilst based overseas. Under this scheme, they guaranteed me a monthly income, whether the apartment was rented/occupied or not. Similarly, it fell to Northwood to handle incoming & outgoing tenants, advertising etc etc.
Did they deliver? Yes. The did what it "said on the tin". No hassles and just regular payments into my bank account for the 5 years of my contract with them.
Would I use them again? Yes. Would I use the Guaranteed income scheme again? Yes, definately.
And nice people to deal with
