It is quite possible to acquire real estate (or anything else) with crypto. It is enough only that the other party agrees with this method of payment.
But I guess the object of your inquiry is more to know if it will be possible one day to transfer/pay large amounts from Wirex? The limits don’t currently allow large amounts of crypto to be transferred, but maybe one day Wirex will set up an escrow service that will allow this to be done, if you know what I mean.
To sum up, if you want to buy an apartment now in crypto from Wirex you have to wait 2 months because the current limits do not allow you to spend more.
I hope that answers your question!
