Congratulations on approaching your Mommy Makeover surgery in such an intelligent and organized fashion.The Mommy Makeover, while yielding almost always incredible results, requires a serious commitment of time, economic resources, and planning and putting into place a great support system. People such as you, who get all their ducks in a row before even talking to a Board Certified plastic surgeon, have more reasonable expectations (and they are usually surprised that they get better results than they anticipated), the recovery goes better and they are back to the real world faster.That being said, the specific answer to your question is all over the board. Some plastic surgeons require a 10% deposit, some a 20%, and some no deposit at all. As far as in house financing is concerned, the majority of plastic surgeons that I know have a relationship with financing companies that work specifically with plastic surgeons. There are several companies out there, including some of the larger banks. that lend money specifically for cosmetic surgery through cosmetic plastic surgeons' offices. I am sure you realize this, but not all plastic surgeons are created equal. Continue your research to determine the top three Board Certified plastic surgeons in your area for your Mommy Makeover without consideration as to price or financing. Have consultations with all three, then work on the financing with the patient care coordinator at each office. Financing and down payment are certainly important. However, once you found the right Board Certified plastic surgeon for you, it may be necessary to postpone the surgery to garner the finances necessary for the down payment, etc. Surgery done correctly by a great Board Certified plastic surgeon is always less expensive in the long run.
