You don't need a lawyer. You contact a mortgage company and work with them. Why is this making you nervous - it's pretty straightforward! I've refinanced a few times and it's taken anywhere from a few weeks to a few months. My mom just spent six months trying to refinance her house and finally gave up because the bank wouldn't agree to the terms they had originally offered. Also, when I have refinanced, we were able to roll the closing costs into the loan once, but not the other times.
