The town has been home to a host of celebrities in the past including French actor Gerard Depardieu and Brazilian footballer Ronaldinho, and is just a few kilometres from the PSG training centre in the nearby town of Saint-Germain-en- Laye.
"The move began last week," an informed source told AFP. Neymar had been camping in a luxury Paris hotel since his transfer to PSG last month.
The property, an architect's home built in the 1950s, is on a hillock and has 5,000 square metres of grounds and an indoor pool, a real estate professional said.
At 25, Neymar became the world's most expensive footballer when he was snapped up by PSG in a 222-million-euro ($264 million) move.
Despite being under contract, Barcelona were powerless to stop the transfer as the French side met the buyout clause in Neymar's contract.
