This was previously known as a mortgage indemnity guarantee (MIG). It is where high LTV lending happens and an insurance policy is taken out by the lender to protect itself – should you default and property values decline.

This cost is passed on to you through this charge. Not all lenders charge this as high loan-to-value loans are rare for buy-to-lets.

Your home may be repossessed if you do not keep up repayments on your mortgage.
