Reference for Avodah Zarah 1:8
וְאֵין עוֹשִׂין תַּכְשִׁיטִין לַעֲבוֹדָה זָרָה, קֻטְלָאוֹת וּנְזָמִים וְטַבָּעוֹת. רַבִּי אֱלִיעֶזֶר אוֹמֵר, בְּשָׂכָר מֻתָּר. אֵין מוֹכְרִין לָהֶם בִּמְחֻבָּר לַקַּרְקַע, אֲבָל מוֹכֵר הוּא מִשֶּׁיִּקָּצֵץ. רַבִּי יְהוּדָה אוֹמֵר, מוֹכֵר הוּא לוֹ עַל מְנָת לָקוֹץ. אֵין מַשְׂכִּירִין לָהֶם בָּתִּים בְּאֶרֶץ יִשְׂרָאֵל, וְאֵין צָרִיךְ לוֹמַר שָׂדוֹת. וּבְסוּרְיָא מַשְׂכִּירִין לָהֶם בָּתִּים, אֲבָל לֹא שָׂדוֹת. וּבְחוּץ לָאָרֶץ מוֹכְרִין לָהֶם בָּתִּים וּמַשְׂכִּירִין שָׂדוֹת, דִּבְרֵי רַבִּי מֵאִיר. רַבִּי יוֹסֵי אוֹמֵר, בְּאֶרֶץ יִשְׂרָאֵל מַשְׂכִּירִין לָהֶם בָּתִּים, אֲבָל לֹא שָׂדוֹת. וּבְסוּרְיָא מוֹכְרִין בָּתִּים וּמַשְׂכִּירִין שָׂדוֹת. וּבְחוּצָה לָאָרֶץ מוֹכְרִין אֵלּוּ וָאֵלּוּ:
We do not sell them what is attached to the ground, [it being written (Deuteronomy 7:2): "velo techanem" ("Give them no resting") in the land]; but it may be sold when it is cut off. R. Yehudah says: One may sell it to him on condition that it will be cut. We may not rent them houses in Eretz Yisrael [(a decree to forestall selling them, a Torah prohibition)]; and it goes without saying [that it is forbidden to rent] fields, [where two prohibitions obtain, "resting" in the land and releasing the land from tithes.] And in Suria [Aram Tzovah, conquered by David, and not of the sanctity of Eretz Yisrael] it is permitted to rent them houses [and we do not decree against it to forestall selling. For even if he did sell he would not be in violation of a Torah prohibition, for "Give them no resting" is written only in respect to Eretz Yisrael. But it may not be sold ab initio, in order to forestall selling in Eretz Yisrael.] But fields may not (be sold) [because two prohibitions relate to them (see above).] And [far] outside of Eretz Yisrael [where selling is not to be decreed against to forestall selling in Eretz Yisrael], houses are sold to them and fields are rented, [but fields are not sold, because two prohibitions relate to them.] These are the words of R. Meir. R. Yossi says: In Eretz Yisrael houses are rented to them, but not fields. And in Suria houses are sold and fields rented. And outside Eretz Yisrael both are sold. [The halachah is in accordance with R. Yossi, provided that he does not rent to three gentiles together, so that he not make a neighborhood of gentiles.]
