Can I set off these costs/losses against capital gains I have made on other properties?

The legal and other costs you have incurred are not allowable against the capital gains you have made on other properties as each property is treated separately for CGT purposes. If you were a property trader and subject to income tax on your sales then there is an argument for including these costs in your accounts as abortive capital expenditure or normal running costs of the business.

“Arthur contacted me the next day.  He phoned promptly and offered me clear and concise advice which he referenced to the HMRC website, taking me through section by section and explaining the implications each step of the way.  He also sent me an MP3 recording of the session so that I was able to absorb the information more fully.  I am extremely impressed by his professionalism.
