Sorry to hear about your father. If it's in any way imminent, don't be worrying about this sort of stuff.
Gifting it now may mean Stamp Duty (1%) and CAT (exempt up to 225,000, 33% thereafter - if the property is worth 220,000, it does not seem CAT would apply)
Waiting to inherit would mean CAT only, if applicable (again, it seems none).
However, the threshold for exemption has been falling rapidly, and the rate has been going up. It may work out cheaper to cough up the Stamp Duty now than encounter higher CAT rates and/or lower thresholds when your father does eventually pass on.
Other charges will be Property Tax and the NPPR charge, and general maintenance of the property. House insurance will be a problem if it is to be left empty for a period of time.
