Costs/Valuations to use for Residential Property Sells

When you calculate CGT, what figures do you use? I assume the value of the property is when I first bought it and not turned it into a buy to let? So the costs and valuation at the point it was no longer my main residence are not applicable? Do all the costs from buying the property original count in the calculation? Can I add the legal fees when changing the property to a buy to let? The last costs are the agent and legal fees when selling Calculating months lived there, i take it the period is from the date you completed to the date you moved out (plus the additional 9mts) Cheers KC

Hi,

You use the disposal value, which is the sum you sold the property for. You deduct from this, the purchase price, which is the price you paid for the property. You can also deduct the costs of buying, selling or improving your property from your gain. These include estate agents and solicitors fees.

Costs of improvement works, for example for an extension and normal maintenance costs such as decorating do not count.  You can use a calculator to help you do this here:

Thank you.
