What a live in flip borrower file teaches about underwriting that rental and flip paper doesn't
Second position lending against a live in flip borrower is different enough from standard rental or flip paper to be worth laying out as a structure. Take a borrower 14 months into living in and renovating a house, seeking a second position loan of $60k. A representative file: house bought at $296k, comps supporting $445k to $465k finished, about $52k of work already in with roughly $40k left. First mortgage balance $271k. A $60k second puts total leverage at $331k against an as-is value an appraiser might put at $372k, with a finished value that's harder to enforce as collateral. Three things matter here that don't come up on rental or flip paper. First, exit certainty cuts both ways: a live in flip borrower often has a tax reason to sell in a defined window, a stronger motive than an ordinary flipper's, but the earliest sale date is set by the residency requirement rather than by when the renovation finishes. If the work wraps early, there can be months of nothing happening with no way to accelerate the exit. Second, the collateral is somebody's primary residence, and foreclosure on an occupied home follows a different process than repossessing a vacant flip, with timelines and protections that vary considerably by state. Third, the repayment source is a home sale whose tax treatment isn't the lender's to verify; underwriting it as though the gain were fully taxable is the conservative approach, since whether an exclusion applies to a given seller is between them and their CPA. The structural point worth keeping: size the loan term off the earliest qualifying sale date plus a real cushion, not off the construction schedule. A term that matures before the borrower's earliest sale date is a term set up to be extended or defaulted.
