I would be interested in your views (from experience or not) about appointing one contractor or two.
This is in relation to repairs and/or planned work. I believe most landlords appoint just one contractor to manage their whole housing stock, but I'm aware that others split their stock and have different contractors working in different areas.
How hard is it to manage two contractors in reality?
Does it increase costs significantly?
What do you do if one contractor consistently outperforms the other?
How do you manage tenants' perception if they hear the contractor in the other area to them does a better job?
Is having two or more contractors a good idea in terms of competition?
