Doubt many do that tbh OR is more for diy landlords I think. But see this thread Oversees landlord - #16 by David122
Because OR don’t do any management. Their mgt plus package is basically like emergency cover option from your landlord insurance. Nothing else.
For finding/choosing tenants, inspections, annual gas safety, checkin/checkout these can all be bought through OR or others. But any repairs or replacement appliances or tenant issues you need to organize yourself and tenant or someone helping you needs to be able to let trades in when needed. And you probably want to come back and visit sometimes.
Not impossible if unfurnished minimal or no appliances and a modern property with little to go wrong, esp if you have a good set of tradesmen you trust to assess work and do at a fair price.
For example sometimes it does help to see an issue in person eg if there is a leak affecting a flat downstairs you can visit and may see sealant round bath needs repair. And fix yourself. Without cost of plumber callout. Or if noise issues harder to deal with neighbours without knocking on their doors unless you have contact already.. Hard to see this sort of thing even on a video call.
Also riskier if tenant knows you are abroad and don’t have anyone responsible for managing/keeping an eye on the place.
Good luck
