I was under the impression he sold his house before he met Anne. Could have been both Charlotte’s and JMJ’s house.
As for the address to be made public, that may be a good reason to move but nowadays there is safety measures one can take i.e. electric fence. But JMJ may not want to feel caged in.
It makes sense that when he married Anne; they do not to live there. But a house does not make all the memories.
