Capital Receipts and Restrictive Covenant

Prior to the sale of an asset creating a capital receipt our authority must pay a number of restrictive covenants.

My question is can the cost of these restrictive covenants be netted of the sale price before assessing the 4% disposal costs that qualify to be met from capital receipts resulting from an asset sale?

Alternatively can the cost of the restrictive covenants be treated as capital expenditure on the grounds that they improve the asset by enhancing its future sale potential?

How do other authorities treat these costs?

Thanks
