I am not clear on whether this debate is meant to be confined to theological arguments for or against, or you are expected to focus on other aspects of this question. Since most religions have very different holy books, perhaps some more general arguments would be of use.
One that comes to mind is that for most people, there seems to be a need for a critical mass to make many religious practices achievable. This implies that religion may very well dictate that one chooses to live amongst others of the same religion. For example, in Judaism, there is a requirement for a minyan, which is ten men, in order to have a proper religious service. Anyone who chooses to settle where there are fewer than ten men is going to forgo that aspect of the religion. On a more practical level, it does take a community to build a house of worship, which most people do want to have. So, in order to have a house of worship, one needs to be in a community of others of the same religion, to provide the wherewithal to build and maintain. For at least two faiths, Judaism and Islam, there are dietary requirements that are almost impossible to fulfill unless one lives in a community with others who are of the same faith. A very long time ago, I found myself in rural Missouri, with no kosher meat available less than two hours away. I was surrounded by cattle ranches, but they did me no good.
The minyon and houses of worship aside, one of the most powerful aspect of religion is its sense of community and culture, which all humans crave in one form or another. This is yet another reason that religion can play a part in one's choice of where to live. We are all "tribal" in many ways and find community and comfort with others like us. The culture of a religion, its customs, is sometimes as much about community as it is about matters spiritual. In those times in Missouri, I often found myself missing things like bagels and Yiddish expressions as much as anything else. When I moved back east, I promptly settled myself in a largely Jewish community.
In today's world, shamefully, religious freedom can be a factor that dictates one's choice. Sometimes this is a matter of life and death. Christian people are fleeing some areas in the thousands, being threatened with conversion or death, a threat that is indeed being carried out. People of the Islam faith no doubt wonder from time to time, given the current political climate in the United States, whether or not they will continue to be safe and free to worship as they choose in this country. Certainly, Jewish people have been persecuted all over the world and have chosen to resettle innumerable times. In Cuba, where the church was essentially outlawed, I would imagine many people resettled where they could worship freely. Thus, religious freedom and safety can be a large part of one's decision about where to live.
If I were participating in a debate on this issue, I would tend to focus on the points that are true of all religions, rather than one just one religion. There are many examples of particular religions that can help one make one's point, but a point needs to be large enough to be generally true.
