In many ways a commercial mortgage is just like a residential mortgage in that you pledge real property as collateral against a loan to either buy or refinance that property. You can also receive a commercial re-mortgage and use it as a line of credit for any business purpose. When you use a commercial mortgage to buy property, or to raise funds for any other business purpose, the lender retains an interest in that property until the loan has been paid in full. Unlike other types of business loans, which usually have a relatively short repayment period, you can take out a loan for as long as 30 years if you like.

The lender receives repayment of the commercial mortgage principal and interest over the lifetime of the loan. If you default on the loan and go into arrears then the lender can foreclose and take possession of the property which was used as collateral.

Generally speaking, the interest on a commercial mortgage is tax deductible and the net proceeds of the loan are not considered to be taxable income. However, you should always check with your accountant to be sure because the tax consequences can be severe should it be determined that your usage of the funds was not for a qualified business purpose.

Should you be seeking a commercial mortgage for the purposes of operating your business, rather than actually buying property, then the lender will either want to re-finance your current mortgage, and include enough money to provide the amount that you are seeking, or they may arrange an equity line where they lend you the difference between the current value of your commercial property and the amount that you owe on the current mortgage.
