Selling an expensive item on Facebook Marketplace. The buyer is keen and offering to pay via bank transfer. Is there any risks as a seller for accepting bank transfer payments? Is there anything I should be concerned/cautious about?

The title sums it up nicely, however to expand a little, I'm just a little cautious. If the buyer transfers the funds to my account and takes the item, is there any risk of them claiming the money back, or is there any issues my end as the seller to be cautious about when accepting bank transfer payments?

Thanks!
