Are there good websites that specialize in this where I can list it? I'm perfectly happy to receive crypto directly. I don't need to have it converted to fiat. I just wonder where potential buyers might visit and I suppose the buyer would want an escrow service as well.
From what country you are selling your property? There's no such established services that specialize on global real state industry because crypto itself is not yet regulated. Your best chance to find possible buyer is to create an ads to social media and indicate the payment method. There's a lot of real-state listing website dedicated on your local country. Dealing online about real-state is very dangerous in both buyer and seller side. It's not possible to deal it online unless there's a trusted 3rd party who will handle the sales for you.
Why not sell it in fiat and bought crypto P2P? There's already a lot of P2P exchange out there that can handle huge transaction like BinanceP2P.
