New lease fees for landlord

A company holds a property as an investment property which is leased to third parties.  Is the legal fees relating to the first lease with each new tenant allowable? 

 

What if the property was held as trading stock (i.e. leased between being developed and sold due to poor market conditions etc), would this change the treatment?

 

What about if an individual held the property rather than a company, is the treatment still the same?

 

Thanks
