Well, it depends…… remember that commercial loans is more than commercial real estate financing. Commercial loans include those loans made out to businesses to support their operations “working capital financing”. In the case of business loans, interest only lines of credit are the norm.
However, in financing commercial real estate, which is probably what you are interested in, most bank lenders will not commit themselves to a long-term interest only deals. There are always written guidelines as to what amortization is required for these deals. Now this doesn’t mean that some kind of hybrid could not be developed in order to help a client out. I can think of a couple of situations where interest only for a period of time will be called for:
Construction loans usually are interest only during the construction period. They might even have built in “interest reserves” where the interest is actually being paid during the construction period from the loan.
Vacant income producing property might be given a limited “interest only” period to allow for marketing and new tenants. In this case, you would have to show the ability to get tenants and the financial strength to be able to afford amortization if you are unsuccessful in getting tenants.
Frankly, I just haven’t seen a permanent interest only product in commercial real estate lending. I very much doubt that there are any lenders out there that do it at anything other than by safeguarding themselves with a very low loan to value.
