Letting- Helpful when you start, but once the house is let they're DREADFUL at getting any work done, answering any queries, calling you back ever, inspecting the parts of the house you want inspecting, sorting anything out when the tenant is moving out or doing anything to earn the money they're getting for virtually nothing. I used a letting agent as I lived in another city and wanted peace of mind. Utterly rubbish!!! And I did raise my concerns politely but they weren't addressed. Still after the tenant moved and the house is sold they forward the tenant's post (ie. bills) to me rather than her!!!
