Disadvantages of commercial loans and mortgages

Additional guarantees.
Depending on the credit rating of your company, the lender might require additional guarantees. These may be provided by you, your partners or your bank and could affect your personal credit rating or your standing with your bank.

Collateral
The lender may insist on a pledge of some asset to secure the loan. Under a security agreement (for personal property), if you default on the loan, the lender is able to foreclose upon the asset and sell it to repay the money owed to the lender. If you are required to provide security, try to limit the amount you have to give to secure the loan. And make sure that when the loan is repaid, the lender is obligated to release its mortgage or security interest and is required to make any government filings acknowledging this release.

Defaults
The lender may define a variety of events that will constitute a default on the loan, including failure to make any payment on time, bankruptcy, insolvency and breaches of any obligations in the loan documents. Try to negotiate advance written notice of any alleged default, with a reasonable amount of time to cure the default.
