late Middle English: from Old French premisse, from medieval Latin praemissa (propositio) ‘(proposition) set in front’, from Latin praemittere, from prae ‘before’ + mittere ‘send’.
wiktionary
From Middle English premise, premisse, from Old French premisse, from Medieval Latin premissa(“set before”) (premissa propositio(“the proposition set before”)), feminine past participle of Latin praemittere(“to send or put before”), from prae-(“before”) + mittere(“to send”).
The sense "a piece of real estate" arose from the misinterpretation of the word by property owners while reading title deeds where the word was used with the legal sense.
etymonline
premise (n.)
late 14c., in logic, "a previous proposition from which another follows, a judgment causing another judgment," from Old French premisse (14c.), from Medieval Latin praemissa(propositio or sententia) "(the proposition) set before," noun use of fem. past participle of Latin praemittere "send forward, put before," from prae "before" (see pre-) + mittere "to send" (see mission).
In legal documents it meant "matter previously stated" (early 15c.), which in deeds or wills often was a description of a house or building, hence the extended meaning "house or building, with grounds" (1730).
