Mums partner 6 yrs want's her to lend him all her life saving for a loan to buy larger house she won't be on deed for.

Hmm I would be hugely concerned about this OP🚩
It would certainly be a no from me.

Aside from this horrendous possibility, has she thought about what living in this house is going to look like? Any money she spends on the house she won’t get back. She will have no legal right to any equity in the property nor will she be able to get money from him.

eg she pays £50k for a new kitchen on the premise that she’s gets it back if he dies. He does die but hasn’t specified that she gets her £50k from the sale proceeds. the executor decides they’re not going to give your mum her money back nor anything else from the estate and it’s all going to his children with a few thousand being bunged to your brother.

OR

She buys the new kitchen, they split up, she says goodbye to her £50k.

If she’s not contributing to improvements on the house, will she have a say if it’s “his” house? Will she feel at home or like she’s a guest? Has she thought about any of that?

Only if i was a proper loan agreement. I wouldn’t loan any money without an agreement and back up plan. My good friend told me a few years ago she was going buy a campervan when she got her pension 25% pay out at 55, but as it was March then and she wouldn’t get the money until December I decided to offer to loan her 12k to get it early. We drafted a proper loan agreement but I also said we needed a plan incase she got hit by a bus, as I didn’t fancy my chances of getting any money from her daughters. So friend signed her pension to me with a letter to state I was to take 12k from it plus 1k interest she insisted on paying, and share remainder between her 2 daughters.

I had never loaned anyone money of that amount before, but I am glad I did as in January this year she was diagnosed with cancer and died 9wks later, age 57. I was so happy that the loan enabled her to have 3 summers with her camper van instead of 2.

He wants her to take all the finacial risk (and actual loss - interest on her savings etc.) for none of the financial benefit?

And to keep their finances completely separate unless and until it benefits him?

Rather than use one of the potentially cheaper and more sensible options pointed out by posters on this thread?

At best he is not very bright and a cheeky fucker. There are also worse possible explanations.

Hard no.

She could ask the solicitor to set it up as a formal secured loan. Trouble is that I suspect it needs to be a “gift” if it intended to be a deposit so he can get a mortgage for the rest. In which case absolutely not, they just need to buy as tenants in common instead.

And yet another NO vote from me! I hope you're going to show your DM the results of this OP.

No way!

Absolutely not!!

But how about they buy the house and it is put solely in her name for the time being until everything is sorted out. Suggest that and if he says no, that will tell your mum all she needs to know.

I guess it's too late for her to say, 'oops I forgot the money is all in fixed ISA accounts and I cant afford to loose the interest and the tax free status'?
That's what I'd say if my HUSBAND wanted my life savings, let alone someone who had gone to some lengths to make sure I couldnt touch any of his money or assets!

This sounds like a romance scam tbh OP

Just saying … years ago, my grandparent had a “business loan” from a friend, a large chunk to start a business (which became very successful. )

This friend died unexpectedly about a 2 yrs after loan was agreed. My grandparent brought by cash to make the first repayment and realised the friend had not told family, no records. It was awkward because it looked like GP was making a sympathy donation, coming around with an envelope of cash as the surviving partner didn’t understand at all about a loan and insisted that life insurance payout had them sorted. There was awkwardness about the money.

Grandparent kept the envelope & never paid it back. Decided that dead friend maybe considered it a gift … or something like good karma.

Get it documented in case you die.

Yes exactly, about the risk imbalance. That in itself is a sign that this situation is not ok for you mum to get into, and perhaps also that he is not to be trusted.

That's a hard no.

He may have had some idea it was a possibility before she knew about it?
What with him being so savvy and careful about protecting his interests.

Your mother's partner is asking HER to take all the risk while HE takes no risk but gets all the benefit of this deal. That in itself is reason to distrust him, no matter how nice he seems and no matter how much he declares that of course he's trustworthy, would see she got back all her money, etc. etc. etc.

Not putting her on the deeds is a huge concern.

No, definitely not!!

Agreed! I was referring to financial advantages IF he were genuine. Which I genuinely don't think he is.

He has no intention of repaying the money so there are 250,000 financial advantages.

I dont necessarily think he's trying to con her but like you say life throws up curveballs and we aren't talking about a fiver here! She needs to seek legal advice and have a loan agreement drawn up and legally witnessed is the only way I could consider this. Money especially at this value should ALWAYS be treated as if you are dealing with a total stranger and love/trust/personal history shouldn't come into it

He already owns a home. He can take a loan on that property.

or she needs get proper loans document signed by him & kept somewhere safe.

Apart from the clear risks and disadvantages to the lender, the financial advantages for the borrower are equally unclear.

Even if a charge was to be sought on the existing property (or other contract was put in place) that would cost anywhere between 1,000 and 2,500 plus VAT. Then there's your mum's loss of interest on her long term savings, which should be at a decent rate (I'm guessing around 5% pa minimum) so a loss of 12.5k at least, plus no guarantee of the same rate now.

A bridging loan for 250k would probably cost about 10k for a few months, so far cheaper.

A savvy, wealthy man would already have worked this all out...

This is one of those threads where I just hope it's not actually real.

Maybe get your mum to read this thread.

She is lucky he never changed his will back to his children as there would be nothing stopping him and she would have lost her money.
