Mind your own business is what I really want to say

It is no ones business whoever they may be WHAT you do with your money.What you want? to say ?then say it
What can he do about it Start as you mean to go on. Once you
give in to his questions and comments it will never end.

He doesn't have to know if he asks just say she's moved. He wouldn't know if she has rented or not. As the other have said buy your Mum her own phone.

Great reply Nonogran. I would say same!

My daughter has a great response if I ask a question too far
“‘I think you’ll find its none of your business!” Said with humour but gets the point across !

I can't see why this bothers you unless there's some sort of family competition over the moral highground by emphasising the richer and poorer theme - if it's simply at the level of him being a nosey git then tell him he can ask her if he's interested, not you. He surely won't know if it's bought or rented will he? Unless he does some significant detective work on Zoopla etc.... Personally, if confronted directly, I'd try and turn the conversation to the housewarming present he's obviously planning to send her as that's the only real reason he needs to know.

"housewarming present" great idea Jess.

They obviously found ways and means and as it is their business I haven't asked would be my response.

grandtanteJE65 It is the OP's daughter, not her brother's.

It’s rude to discuss money but if he feels it’s his right to know / ask he should speak to the property owner!!

What is a DD? I'm presuming it's a daughter but why the double D?
A DC?

If he isn’t part of your lives, then tell him to mind his own business or wind him up by saying”Wouldn’t you like to know?!”

Just say, mind your own business. He likes or lumps it.p

If he enquires ask him what he has been spending his money on, how did he afford the car, house, sweater etc that should shut him up or tell him the accountant you now have wants to go over mother's finances to make sure they are in order and that any pension etc she is due is in her bank. You probably will never see/hear from him again.

Listen to any politician being interviewed, you will soon get the hang of it.

??? love it MOnica!

'What do you mean?' is a good one for awkward questions.

Just say you are not privy to the ins and outs of your daughter’s finance, and would not be so rude as to ask her!

i disagree with some these approaches, not in a theoretical but a pragmatic way.
he has control of the OP's mother.
she can only communicate with mother through him.
maybe mother cannot operate a phone.
if he chooses, he can cut off OP from speaking to mother.
they are 300 miles away; she cannot just pop over to see her.
so, for her own reasons, i think it wise to keep on the right side of him.
avoid too much directness, which does sound rude.
be vague, yes, she's very fortunate. how's things in mother's house?
that's what i think anyway.
good luck Op.

The ploy of “forgetting” relevant details works well.
Suggesting to your brother she’s inherited the gene to be careful with money might flatter and distract him.
Claiming to have no knowledge as someone else has been involved removes responsibility from you. Refer your brother to your husband as he alone has discussed the purchase of the house with your daughter.
Alternatively, massively exaggerate your contribution so it is clear to your brother it’s untrue and therefore no longer a subject to be discussed.

Best answer, works every time.

I tell you what IS rude! Asking someone about their personal finance arrangements!!! What an absolutely revolting man, if you excuse my displeasure? I would look at his fizzog-grin and say"wouldn't you love to know?!" Then ignore him! How very very rude of him! Don't let him bully you any more that's my advice! It's your business darling nobody else's

MayBeMaw I love your answer.
Shout ‘Hello? Hello?’ Down the line if that question comes up.
Problems with the line, stick with it and no one upset.
