Unlike residential lending, commercial investment properties are viewed more conservatively. Most lenders will require a minimum of 20% of the purchase price to be paid by the buyer. The remaining 80% can be in the form of a mortgage provided by either bank or mortgage company. Some commercial mortgage lenders will require more than 20% contribution towards the purchase from the buyer. What a bank/lender will do is subject to their appetite and the quality of the buyer and the property. Loan to value is the percentage calculation of the loan amount divided by purchase price. If you know what a lender's LTV requirements are, you can also calculate the loan amount by multiplying the purchase price by the LTV percentage. Keep in mind that the purchase price must also be supported by an appraisal. In the event that the appraisal shows a value less then the purchase price, the lender will use the lower of the two numbers to determine the loan that will be made.
