Answer: After the offer and contract have been negotiated and accepted, the mortgage contingency period will begin. 45 days is allocated to obtain a mortgage commitment. Due diligence now begins in earnest with the ordering of inspections, title insurance, environmental, and survey (if needed). Once received, the mortgage processors review the title, appraisal, and environmental issues if any, to build their file for closing. The contract should best case allow 90 days for closing, but closings often occur in 45 to 60 days on average.
