My younger sister has a large deposit saved, but is unable to get a mortgage as her government job is contract (although she has had the position for years)
We have the option of going guarantor for her to buy an apartment, or loaning her the money, with no/little interest, ourselves.
We trust her 100% and know that she will pay us back/service the mortgage.
The only downside is if she were to get ill or lose her job completely (highly unlikely) and was unable to make repayments.
Would you do this for a sibling?
