The day a tenant moves in, the policy has to change.
The most expensive mistake in rental property is also the most common: keeping the homeowners policy after the tenant moves in. A homeowners form is underwritten for an owner-occupied residence. Once the property is rented, the risk the carrier priced is not the risk they have, and a claim can be denied on that basis alone. Not reduced. Denied.
What you need instead is a landlord policy, most often a DP-3 dwelling fire form. It is built around three things a homeowners policy either handles differently or does not handle at all: the structure, your liability as an owner rather than as a resident, and loss of rental income when a covered loss puts the unit out of service. That third one is the coverage owners forget and miss the most, because the mortgage payment does not pause while the unit is being rebuilt.
Pennsylvania does not require landlords to carry insurance. Lenders do, on any mortgaged property, and the practical case is stronger than the legal one. The Landlord and Tenant Act of 1951 puts habitability obligations on you, Pennsylvania applies comparative negligence so a court can apportion fault, and a tenant injury claim against an uninsured owner reaches personal assets directly.
Two details catch people repeatedly. Vacancy clauses limit or suspend coverage once a property sits empty past a stated number of days, usually 30 or 60, which matters during turnover and renovation. And a short-term rental is a different animal entirely: most landlord policies exclude transient occupancy, and a platform's host protection is not a substitute for your own coverage.
We write single-family rentals, twins, duplexes and small multi-unit buildings across the Lehigh Valley and both states, and carrier appetite for older rental stock varies enormously, which is exactly what shopping twenty of them is for.
