Is freehold always better?

[Mina]

I have the leasehold on my buy to let flat, it has about 110 years to run. I'm wondering if it's worthwhile purchasing the freehold - it will cost a couple of thousand pounds. Can someone explain to me the advantages if any of owning the freehold? The block of flats is run by a management company, they seem to be doing a good job of things and don't cost the earth.

Any thoughts much appreciated.
