Straightforward accounting for landlords is pretty simple. However, with the new S24 measures coming in from April, many landlords are looking for new ideas on how to run their particular operation in the most tax-efficient way. Obviously, I don't know anything about your situation but my advice is to proceed with extreme caution at the moment because landlord taxation is a very fluid subject right now and I can tell you that very few of the 'experts' out there really understand the full implications - especially when it comes to proper tax planning for the long term and with ones partners/spouses and children becoming involved.
I'd be happy to give you some good pointers if you want.
(I'm off to bed now though!)
