Question: We have rented our house for the past five years and are now able to buy it. Should we remove the mezuzos and reaffix them? Answer: There is a machlokes among the rishonim as to whether the obligation upon a renter to affix a mezuza is mideoraisa or miderabannan . The Sefer Hachinuch (423) and the Nimukei Yosef (Mezuza 6b) maintain that the obligation is mideoraisa , subject to a thirty-day exemption, and this also appears to be the implication of Rashi (Menachos 44a). Tosafos (Avoda Zara 21a), the Rosh (Chulin 8:26) and the Mordechai (Hilchos Ketanos 950), however, hold that the obligation is miderabannan . The Sdei Chemed (Mem 112) notes that this is the majority view. The Pischei Teshuva (YD 286:18; Nachlas Zvi 286:22; 291:2) raises the question of whether one who initially rented a house and later purchased it must recite a new beracha .

The Mishna Berura (104:27) likewise emphasises that someone davening must remain silent during kaddish so that they can hear the chazzan say yehei shemei rabba . The Taz (OC 125:2) and R’ Akiva Eiger (OC 125:1) write that the tzibbur should recite the pesukim together with the chazzan , who says them aloud. However, if the chazzan recites the pesukim  with the  tzibbur , those relying on shomea ke’oneh may simply not hear him. The Mishna Berura (Biur Halacha 125:2) notes that the chazzan should not recite a davar shebikedusha entirely on his own, and therefore raises the possibility of beginning s...
