So somehow you made "clear" that you are a Kurd. Because of that you know how Kurdish girls are like..money..money..money. I can relate to that as i myself am also a Kurd. However bra, there is much more to the "game" of marriage then simply the things you mention.
Islam has boundaries and if you are within those boundaries it is permissible, the question
however it is not whether it is permissible or not when marrying, when we marry we want a blessed marriage. As Kurds we KNOW how many Kurds in Kurdistan it has become a "norm" to divorce. So instead of simply to look at if it is permissible to marry certain girl from a certain religion, one must rather look at what Islam or Prophet Muhammad(saws) has advised us to look to when marrying.
The Prophet (ﷺ) said, "A woman is married for four things, i.e., her wealth, her family status, her beauty and her religion. So you should marry the religious woman (otherwise) you will be a losers.

From his advice we see that he rather advice us to marry somebody that has put religion on #1. A Christian sister rather has not
put religion on #1. Why do i say this?
In the Qur'an Allah says,
"And say, "Truth has come, and falsehood has departed. Indeed is falsehood, [by nature], ever bound to depart." Qur'an 17:81
The person that ponders a lot will see that no other religion stands firm EXCEPT Islam. So for a Christian sister still being a Christian before you marrying her, shows rather she does not question things and is eager to want to pursue knowledge and understanding and what is truth.
So what am i saying? Look for a wife that has put Islam on #1. Don't look at ethnicity. She being a Turk, Kurd, Arab, Persian, German, or whatever, as long as she does not pursue culture/nationalism but rather follows the path of Islam, that is a suitable wife. To find such a wife, first clean your self so to say. Do you deserve such a wife? If yes, based on what do you say you deserve such a wife?
Such a wife, in Islam "mahr" MUST be given, however it doesn't mean it "has" to be money. Rather you HAVE to give her something. I once have heard that a sister asked for a copy of the Qur'an from her future-husband as mahr.
Right now bra, i would advice you, find out what is culture and what is religion. Find out what is permissible and what not. Go and clean your own character and follow Prophet Muhammad(saws) his example. Do remember having a long beard doesn't make you suddenly a good Muslim. That is the cover, rather clean your heart from loving money, pursuing your desires, not desiring to want to listen to music, be consistent with doing your daily prayers, being good to your parents and people around you. Not mixing with girls..etc etc.
