He’s lighting up the real estate world!

A unique and historic lighthouse residence in the Chesapeake Bay was listed this week for $450,000, but reaching it requires a boat, the owner mentioned to The Post on Thursday.

This three-bedroom dwelling, known as the Smith Point Lighthouse, is located about three miles off the coast of Virginia and offers stunning ocean vistas from a highly secluded spot, suitable for those with an adventurous streak, according to Dave McNally, 74.

“The most fun part is you get a 360-degree water view. It’s kinda like you’re in an aquarium with everyone circling around you,” he said.

“On a night when the sea is calm, I could hear the sound of dolphins’ blowholes opening and closing,” he shared. “Owning this lighthouse has been one of the highlights of my life.”

But the wave-battered abode, which McNally paid $170,000 for in 2005,  also comes with its share of of wild idiosyncrasies.

“It’s out in a part [of the sea] that’s dangerous for shipping,” he said. “When a storm comes up, waves can get 12 feet tall.”

“But the structure is so sturdy, and it doesn’t sway,” he added.

To reach the house, which McNally and his family used as a summer home, visitors must enter by climbing a ladder between two windows at the rusty base of the structure. 

While living there, McNally generally took a boat to land every week to buy groceries — and once had a big vessel he dubbed his “floating pickup truck” while fixing it up.

Built in 1897, the lighthouse has four levels, with the first now serving as a kitchen and a living space, according to the real estate listing.

The second level has three bedrooms with a wave watch-room land a lantern room above that.

McNally said he initially moved from Michigan to the home because he’s a boat-loving “water nut” who “like[s] adventure.”

He now wants to sell the place due to the recent birth of his grandchildren, he told homes.com, which was first to report the listing.

Bringing very small children to the lighthouse would be too hazardous, said McNally, who is selling the house “as is.”
