Kol Hakavod what you did for your daughter.
However, i am wondering if the money loss was discussed with a dayan who deals in such.
Now i remember that when one of our sons went to Eretz Yisroel, he was unhappy with the yeshiva he went to. Luckily, he found a place who was ready to accept him(where he thrived B”H and is still in Eretz Yisroel learning, raising a beautiful family and doing loads of chesed). The first yeshiva was very understanding about the situation and reimbursed us. In return my husband gave them a nice donation.
If this seminary is not reimbursing you, then, in my opinion it is a business and not L’shem shamayim.
There are seminaries in N.Y. too such as Reb Bulka, where the girls can work towards a degree as well.
