In the refinanceFull() function, if the borrower is the caller, it signifies a renegotiation offer. The borrower will clear the accrued interest, permitting them to repay the accrued interest without waiting for the full loan repayment. 
However, if netNewLender < totalAccruedInterest, theres a risk of overflow. Consequently, refinanceFull() will revert, preventing the borrower from accepting the renegotiation offer.
