Once your offer on a place is accepted, you’ll need a mortgage commitment letter. It doesn’t need to be from the same bank that preapproved you. In fact, you’ll want to shop around for rates, and if you’re buying a co-op, make sure you are working with a lender that has a lot of experience with co-ops. Even better, when you’re buying in a co-op or condo, find a lender who has already approved loans in that particular building, which can expedite your financing, because a lender must approve the building itself, not just you. They’ll look at things like the percentage of owner-occupied units, upcoming large capital assessments, and the number of owners in arrears on their carrying charges.
To obtain a commitment letter, you’ll submit a lot of financial information, the apartment is appraised, the lender or mortgage broker looks at the building itself to make sure it meets their lending guidelines, and finally they give you a commitment to lend up to X amount by Y date at Z interest rate.
Once upon a time you could go to sleep on that assurance and quit worrying about financing the biggest purchase of your life. These days, the letters are riddled with conditions. Some lenders try to sneak in “subject to appraisal” if they’ve issued the letter before the appraisal or “appraisal subject to underwriting review”—essentially, these are loopholes inserted by the lender that allow them to walk away from the “commitment.”
Work with your mortgage lender, real estate attorney and real estate agent to make sure you are crystal clear about any possible circumstances--both within and outside of your control--that might prevent you from getting the mortgage. This is critical if you decide to put in an offer without a mortgage contingency (a frequent necessity in the highly competitive New York City real estate market). By waiving the contingency, you risk losing your deposit if you’re unable to buy the apartment because the financing falls through--a very expensive proposition in New York.
