Financing on commercial mortgages is very different to financing on residential mortgages. The process can take anywhere from 1 month up wards. Along with an appraisal a phase 1 environment inspection can be required depending on building type. Always give yourself more time and do not rush the financing clause as it is there to protect the borrower. With residential financing a 5 day financing clause is the norm. With commercial financing 30 days or more is the norm depending on building type and processes involved.
