Yes, in most cases, you should lock your interest rate early when buying on 30A, especially once you are under contract.
Clay Owens approaches this with one focus, protecting the deal, not trying to time the market.
If you are closing within 30 to 45 days, locking early is typically the right move. Rates can shift quickly, and locking secures your monthly payment so there are no surprises before closing. On 30A, where timelines can move fast, that certainty matters.
Clay consistently advises buyers to focus on what works for their numbers. If the rate fits your budget and goals, locking removes unnecessary risk. Waiting for a lower rate can backfire just as easily as it can benefit you.
If your timeline is longer, closer to 60 to 90 days, you may have room to wait. This is more common with new construction or longer closings, but it comes with risk if rates increase.
One strategy Clay often recommends is negotiating a float down option with your lender. This allows you to lock now while still having the ability to take advantage of a lower rate if the market improves before closing.
At the end of the day, this is not about chasing the lowest rate. It is about securing a deal that works and protecting it all the way to closing.
If you are under contract and comfortable with the payment, locking early is usually the smart move.
