Yes, it's ok. In New York in the past few years, there has been about a 15 percent increase in credit union loans to home buyers, especially first time buyers. As portfolio lenders, credit unions usually keep at least half of new loans in their own investment portfolios. Borrowers shopping for a mortgage might find that credit unions can offer slightly lower closing costs than banks. Another advantage is that most credit unions retain the servicing on all of their mortgage loans. As member-owned cooperatives, they have an incentive to be responsive to their customers.
