Setbacks and buffers both create some space between stuff, like your property line or a stream, and they also put a limit on what you can build there. In most counties, local zoning laws usually decide how big these setbacks and buffers should be.

In a simple picture, imagine you can't build close to your side boundaries because of the setbacks and you also can't put up structures near the water because of buffer requirements. So, the only part of your lot you can develop without breaking these rules is called the "developable area."

If you're not living there full-time, waterfront properties can be lucrative for short-term rentals, such as Airbnb or VRBO.

Waterfront properties often provide easy access to various water-based activities such as swimming, boating, fishing, and kayaking.

Waterfront properties tend to hold their value well and often appreciate over time, making them a sound long-term investment.
