Refurbished Leaseback

Can anyone help with the following please re. a leaseback that is a refurbished property as opposed to a new build?:

What building defects guarantee should one expect on a refurbished property? Does the vendor have to undertake / make available a condition survey or similar prior to sale?

During the lease does the management companys' repair responsibility extend to structural repairs and exterior decoration as well as internal upkeep?
