Seasoning from certificate of occupancy versus first rent payment, and which one the lender actually uses
Most BRRRR models assume the refinance clock starts ticking when rehab wraps, but the CO date and the first rent payment can be weeks apart, and I have seen commitment letters that tie seasoning to neither. Some DSCR lenders count from the first full month of rental income on file, which means a lease signed two weeks after CO costs you a month of seasoning time you did not plan for. Others count from the date the final draw was disbursed on the bridge, which can precede the CO by weeks if you passed inspections early. The gap between those two interpretations on a standard six-month seasoning requirement is small in calendar terms but meaningful when your bridge rate is running. What is the actual language your lenders use, and does it vary by lender type, portfolio versus DSCR versus bank balance sheet?
