Q. We bought our house 23 years ago and we expect in the next six months to move into a bungalow that my wife inherited, and rent out our current home. We bought the house in 2002 for £127,000 and it is worth about £360,000 — a gain of £233,000.

If we rent out the house for ten years then sell it would the liability for capital gains tax be based on the value when we first started letting the property, £360,000, or would it be calculated using the initial purchase price and then prorate the gain to the number of years it was let?

Your situation is not uncommon and I have had to guide many of my clients through the tax complexities of simply moving between homes. What appears to be a straightforward decision has a number of tax repercussions.
