the.com/realty

means Real estate considered as property — land and the buildings fixed to it, in the sense used for buying, selling, and owning.

from Built from 'real' in its old legal sense of 'relating to immovable property' (from Latin 'res,' meaning thing — as opposed to 'personal' property, which could move), plus the noun-forming suffix '-ty.' The legal distinction between 'real' property (land, houses) and 'personal' property (everything else) is centuries old; 'realty' emerged as a tidy shorthand for the former, and stuck in the trade.
