Fourplex (Quadplex)
A 4-unit residential property. The largest property still classified as residential (not commercial) for DSCR purposes; eligible for 80% LTV and standard DSCR pricing.
Why it matters on a DSCR loan
The fourplex is the sweet spot for many DSCR investors: four rent checks under one roof while still qualifying as residential, avoiding the tighter terms of 5+ unit commercial multifamily. Because DSCR is calculated on aggregate rents against one PITIA, a single vacancy hurts far less than it would on a single-family rental. The classic mistake is stepping up to a five-unit building for marginally more income and unknowingly crossing into commercial underwriting with lower LTV and different appraisal requirements.
