It appears that there's a clear trend of our forefathers, Avraham, Tzhak, and Jacob, to dwell in tents in the Holy Land, wandering from one place to another, instead of settling down, taking hold of the land and building houses, despite the fact that the Land was promised to be theirs.
For example Avraham:
...וְהוּא יֹשֵׁב פֶּתַח־הָאֹהֶל ... וַיְמַהֵר אַבְרָהָם הָאֹהֱלָה אֶל־שָׂרָה
...וַיְבִאֶהָ יִצְחָק הָאֹהֱלָה שָׂרָה אִמּוֹ...
IIRC, they were sitting in one place for years - Hebron, Kiryat Arbah, Avraham even bought a graveyard and Yakov bought a piece of land in Shechem (for Yossef's grave?), but the Torah does not mention them dwelling in houses*. (There's only one place in Succot where Yaakov mentioned "building a house for himself", however many interpret it metaphorically - he built Beis Midrash, he built Beis Israel, etc, and the Torah itself does not mention him actually living in a house).
On the contrary, we can see that in parallel many Biblical figures lived in houses:
For example Lot:
וַיֹּאמֶר הִנֶּה נָּא־אֲדֹנַי סוּרוּ נָא אֶל־בֵּית עַבְדְּכֶם ...:
וַיָּבֹאוּ אֶל־בֵּיתוֹ... ׃
... אַנְשֵׁי הָעִיר אַנְשֵׁי סְדֹם נָסַבּוּ עַל־הַבַּיִת...
Or Betuel and Lavan:
...וְאָנֹכִי פִּנִּיתִי הַבַּיִת וּמָקוֹם לַגְּמַלִּים... and many many others in the same Parasha
... וַתֻּקַּח הָאִשָּׁה בֵּית פַּרְעֹה...
As the Torah does mention very explicitly all other characters living in houses and doesn't mention the forefathers doing so, I think this can not be attributed to simple omissions.
What might be a reason for such strange behavior?
I found it interesting that this behavior is consistent with some historical theories that present the Israelites as nomads and wanderers even in "their own country", unlike all other surrounding nations - Egyptians (Pharaoh) or Babylonian (Betuel) that lived in fixed settlements.
*Except for one place (I could find): "וַתִּקַּח רִבְקָה אֶת־בִּגְדֵי עֵשָׂו בְּנָהּ הַגָּדֹל הַחֲמֻדֹת אֲשֶׁר אִתָּהּ בַּבָּיִת"
