I wish I’d just sold my house!!!
Get an agent to find and reference a tenant.
Tenancy agreement from here Legit AST
Join a deposit scheme.
Get an inventory (you can get the agent to do this if you want)
Find some local tradesmen you trust!!! (Landlord’s gas safety check, electrical check [only needs to be done every 5 years] and for all other niff naff and trivia)
You can’t guarantee what the tenant is going to be like, let an agent find them and then if you meet them usually your gut is right.
