I've never heard of Bitcoin being used for payments in real estate and I had never given a thought to why it might not be accepted. I've heard about the acceptance of Bitcoin in Dubai, that it can also be accepted as salaries by workers there, and I think it'll be good for other cities and counties to emulate it. I want to think that in a country where Bitcoin is not banned that it shouldn't be a problem to accept it, after p2p transactions, tax matters can be worked accordingly. The major reason that I can think of is adoption, Bitcoin is volatile and people prefer fiat that is easy to spend
If Dubai is accepting Bitcoin payments for real estate, I wonder if El Salvador is doing the same? After all, it was the first country to adopt Bitcoin as legal tender.
I know the main reason why many realtors are skeptical of crypto is because of market volatility (especially when it comes to altcoins). But with the advent of centralized payment gateways (eg: BitPay, CoinPayments) this shouldn't be much of a problem. Such services will immediately convert crypto to Fiat during the payment process. Give it a few more years, and you'll see crypto being used more throughly as payment method for real estate. Maybe it will take another decade? We'll see...
Bitcoin is ledger tender in El Salvador and I'm sure some realtor do accept it for payment of Real Estate, this might not be very common but since El Salvador accepted Bitcoin as a ledger tender I know it will attract more investors to have interest for bitcoin. Crypto in general not being accepted for payment is because it is still gaining more recognition.
I don't think any realtor will be comfortable to accept altcoins as payment because of the volatility of altcoins.
