Step 2: Put property on the market, listed as having a mile of beach
Step 3: ???
Step 4: Profit
There's no way this could backfire, unless the buyer asks how big your ruler is. But a true gentleman never questions the size of another's ruler, so you should be in the clear.
E.g.: properties are routinely described as “X minutes away from beach”, where in reality it’s impossible without teleportation.
at the speed of a bullet
Effectively no. MythBusters said a 30-06 shot straight up could hit 10K feet and would take just under 1 minute to hit the ground. I'd be comfortable asserting that a 30-06 is about the largest 'normal' cartridge. Bigger ones definitely exist, but they're a niche.
Handgun rounds are generally a lot slower and lighter than a 30-06, so they'll all be even quicker to reach the ground. Plus, to hit the beach, you'd shoot at about a 45 degree angle instead of straight up, which would reduce the height reached.
Low gravity & no atmosphere- bullet reaches escape velocity and wanders off to space.
Very high atmosphere & fired high up above ground (if any - eq. gas giant) and bullet might take quite a while to fall.

can make ULR bullets drop faster or slower depending on crosswind direction and strength.
Well, this could be a problem, of course, if you are selling an island.
a U shaped beach would be listed with half its effective beach area
Or it goes through a real world court system where judges take very dim views to that level of pedantry...
