Insurers may have specific requirements that you or an agent you appoint carry out regular inspections otherwise some parts of the insurance won’t be valid. Check the policy wording carefully
You’ll also have to figure how you will manage if not there - everything from checkin inventory and inspections and checkout to dealing with tenant, letting tradesmen in for boiler service annually etc - does someone else have keys and can keep an eye on for you? Sorry if all ridiculously obvious
