The admin of the HomeFi contract can set lenderFee to greater than 100%, forcing calls to lendToProject() to all projects created in the future to revert.

Mitigation:

Consider adding a reasonable fee rate bounds checks in the replaceLenderFee() function. This would prevent potential griefing and increase the trust of users in the contract.
