Without the informationrequested in my first/previous response, I can only give you a general answer,but I hope this helps.
Supplies of land and buildings, such as freehold sales, leasing or renting, are normally exempt from VAT. This means that no VAT is payable.
Once you have opted to tax all the supplies you make of your interest in the land or buildings will normally be standard-rated, and you will normally be able to recover any VAT you incur in making those supplies.
I have assumed you did not opt to tax (charge VAT on) land and buildings for VAT purposes. This being the case there is no VAT to pay on the sale of holiday cottages.
If you did there are circumstances when you can revoke this option to tax. An option to tax cannot normally be revoked until at least 20 years have passed.
More information on this is covered under 8.3 on VAT Notice 742A here
