Hi Amanda. Here's my read on your question. First, check Ms. Brocco's link below for FHA approved Condo buildings. That will give you proper info as to who would allow a 5% or lower deposit. Second, go to a Mortgage professional and get yourself pre-qualified for a loan and ask them about first time buyer programs and FHA approved buildings and financing. Third, get yourself a Broker to help you navigate the purchase process, you'll need one. Now, you can also go with option three first. The broker will arrange for you to get pre-q'd, they'll also check into the buildings and what may be available. They'll also set up all appointments.
The reaility is this, obviously you are trying to do this on a shoestring. I don't know what your work or credit history is. I don't know what type of assets you have or your income or if you're getting a cash gift from someone for your downpayment. You wll need to consider closing costs and some amount of post closing liquidity. I strongly advise you work with an experienced real estate professional. Good luck.
