Questions on freehold

Hi i have some queries regarding freehold properties here in dubai:

A) after u purchase them for say USD 1 million (average price) does the other miscellaneous charges is one time payment or yearly?

B) the maintenance fees of per sq ft ( average 18-25k per year) is paid every year forever?

C) what according to your experience is better : apartment or villas?

D) is the said property forever ours? Even if we leave uae and live somewhere else? Even if i leave it empty? Does my staying has to do anything to do with the freehold validity?

E) do I need to make a specific will/registry to pass the property down immediate family members (blood relationships) if anything happens to me or its done automatically?
