Investing in Upper Darby, PA — Market Analysis
Upper Darby is one of the lower-basis entry points in Pennsylvania, with a median home price around $240,000. Upper Darby is an urban infill market where small multifamily and converted stock dominate. Per-door rents run higher than the metro average, but so do turnover, maintenance reserves, and the spread between gross and effective rent.
Buying a rental property in Upper Darby on a DSCR loan means putting a minimum of $48,000 down (20% of purchase price), leaving a loan amount of $192,000 at 80% LTV. At current DSCR investor pricing near 7.50%, principal and interest on that loan runs about $1,342 per month. Add Delaware County property taxes of roughly $298/month and landlord insurance of about $96/month, and your all-in PITIA lands near $1,736/month. That PITIA figure — not the P&I — is what the lender divides your rent into.
A long-term lease in Upper Darby should generate roughly $1,675/month in gross rent. Against a PITIA of $1,736, that produces an estimated DSCR ratio of 0.96x. That falls just short of the 1.0 minimum. This is a very common outcome in Upper Darby and it does not kill the deal: moving to 25% down ($60,000) cuts the payment enough to close most of the gap, and several shelves will fund down to 0.75 with a rate add-on.
Two Pennsylvania-specific items to build into your model: Pennsylvania millage is set at the school-district level and several counties still assess off decades-old base years, so two similar houses a mile apart can carry very different tax bills — always pull the parcel's actual millage before finalizing a DSCR file. In Upper Darby specifically, effective property tax on investment property runs around 1.49% of value annually — about $3,576 a year at the median price — and landlord insurance near $1,152 a year.
On return metrics, Upper Darby pencils to an estimated cap rate of 5.19% using a 62% NOI margin, and a gross rent multiplier of 11.9. Monthly cash flow on a long-term lease at 20% down is estimated at $61 negative. Negative cash flow at 20% down is common in appreciation-led markets; investors here typically increase the down payment, buy below median, add a unit, or run the property short-term to close the gap.
