Legal analysis: the impact of using provident fund as a guarantee for others to buy a house is that the lender needs to bear the guarantee responsibility when it does not repay the loan. If the provident fund management center does not know about other people's housing security, it will not have an impact.

Legal basis: Regulations on the Management of Housing Provident Fund
