The
Washington Post (Archive) doxxed Jimmy and possibly Chris:
Drew Harwell and Taylor Lorenz said:
In one leafy neighborhood, he owns five homes where he houses friends and employees — basically an entire cul-de-sac.
Drew Harwell and Taylor Lorenz said:
He also, with less fanfare, started snapping up real estate in the neighborhood where he grew up, offering premium prices for five brick homes near a senior center and an agricultural history museum and buying them under the name of a shell company to preserve his privacy, real estate records show. His mother — who has taken an active role in at least one of his business ventures, including helping execute the MrBeast Burger endorsement deal, according to a
legal filing — still lives nearby.
The phrase "agricultural history museum" stood out to me, as there aren't that many of those.
Turns out there's only one in the Greenville, NC area and it's right next door to a senior center:

One of the cul-de-sacs that backs onto the agricultural history museum has a lot of houses owned by "Heintzelman LLC":

Every house in the picture except for this one is owned by the LLC:

The
New York Post (archive) confirms the existence of one holdout:
There remains just one hold out house, which Donaldson’s former neighbor attributed to the family likely wanting their kids to finish school.
These are the only houses in the neighborhood that aren't owned by individuals.
Some more quotes from the article that describe the houses:
Drew Harwell and Taylor Lorenz said:
The home-shopping spree became a source of local gossip and envy: One four-bedroom home with a sunroom and wooded backyard, which Donaldson’s company bought for $680,000 in 2021, had been sold four years earlier for roughly half that price.
This LLC-owned house has a wooded backyard and a sunroom (highlighted in pink):

The gabled suburban houses, with their dormer windows and half-acre lawns, give few hints of their unconventional status; one has a giant driveway with yellow parking bumpers for seven cars.
The LLC has a local lawyer as its officer:

The address of Jimmy's house is the one with the parking lot driveway.
Jimmy wasn't always smart enough to use a lawyer as his agent for his shell companies.
This is probably Jimmy's mom's house judging by the date of dissolution (and the listed owner, Susan K. Parisher):
