2-4 Bedroom residence, anytime within the next 5 months

We're a family of 4 with a small (10 lb), non-shedding dog, who need a 2-4 bedroom apartment, house, condo or townhouse near Blue Mountain Beach (preferably no farther east) anytime within the next 5 months. We live in Fort Walton Beach right now, and can move after April 1st. We would prefer unfurnished, but furnished wouldn't be a deal breaker under the right circumstances. We can go up to $1600/month, and I'd ideally prefer to be on or very near 30-A. We are long-time Destin business owners and are very conscientious and responsible. Thank you!
