How do I calculate cash-on-cash return on a Pittsburgh rental?

Cash-on-cash return is your annual pre-tax cash flow divided by the total cash you put into the deal - CoC = Annual Cash Flow / Total Cash Invested. Take a Brighton Heights 3BR single-family purchased at $135,000 with $43,000 cash in and $4,200 of annual cash flow after PITI and operating expenses: that is a 9.8% cash-on-cash return. In Pittsburgh 2026, 8-12% is solid, 12%+ is excellent, anything under 6% probably means the rent is below market or you put too much cash in.

What is the formula?

Cash-on-cash return measures the yield on the actual dollars you committed - not the property's total value, just your cash.

CoC % = (Annual Pre-Tax Cash Flow / Total Cash Invested) x 100

It is the rental investor's answer to "what is my deal earning me on the money I tied up?" Different from cap rate (which ignores financing) and different from total ROI (which includes principal paydown and appreciation).

What counts as annual cash flow?

Cash flow = gross rent - vacancy - operating expenses - debt service. Be honest about each line:

• Gross rent: realistic monthly rent x 12, anchored to lease comps in the same census tract.
• Vacancy: 5-8% of gross rent for stable Pittsburgh blocks, 10%+ for transitional or higher-turnover sub-markets.
• Operating expenses: property taxes (Allegheny County millage + school district), insurance, repairs/maintenance reserve (typically 8-10% of rent), property management (10% if hired out), turn costs reserve, water/sewer if owner-paid, lawn/snow if applicable. The 50% rule (operating expenses = 50% of rent) is a fast filter, not an answer - run line items.
• Debt service: annual mortgage P&I (principal + interest only - escrow taxes/insurance are already in the operating expenses above).

What counts as total cash invested?

Everything you wrote a check for to get the property rent-ready:

• Down payment
• Closing costs (lender fees, title, transfer tax - Allegheny County + Pittsburgh combined transfer tax is meaningful)
• Initial rehab to bring the property to rent-ready condition
• Initial reserves you funded out of pocket (some investors include 6 months of operating reserve, some do not - be consistent)

Do not include the loan principal - that is the bank's money, not yours. Cash-on-cash measures yield on your cash, not on the property.

A Pittsburgh cash-on-cash, step-by-step

Take a Brighton Heights 3BR/1BA single-family. Purchase price $135,000, market rent $1,650/month ($19,800/year). 25% down conventional rental loan at 7.50% on the remaining $101,250 (approx $708/month P&I).

Cash invested:

• Down payment: $33,750
• Closing costs: $3,900
• Light rehab + turn: $5,500
• Total cash in: $43,150

Annual cash flow (rounded):

• Gross rent: $19,800
• Vacancy 7%: -$1,386
• Property taxes (Allegheny County + City of Pittsburgh + school): -$3,200
• Insurance: -$950
• Maintenance reserve 8%: -$1,584
• Property management 10%: -$1,841
• Operating cash flow: $10,839
• Mortgage P&I: -$8,496
• Annual cash flow after debt: $2,343

Cash-on-cash: $2,343 / $43,150 = 5.4% with full property management.

If you self-manage instead of paying 10% PM, you save $1,841/year - cash flow becomes $4,184, CoC jumps to 9.7%. That swing is why "good" cash-on-cash always has an asterisk: who is doing the work matters as much as the numbers.

What is a good cash-on-cash return in Pittsburgh?

• Under 6%: the deal is thin. Either rent is below market, your cash-in is too high (too much rehab or too low leverage), or operating expenses are eating you. Re-underwrite.
• 6-8%: acceptable for stabilized A-class property with low risk. You are mostly betting on appreciation and principal paydown, not cash flow.
• 8-12%: solid. This is the realistic target for B-class Allegheny County single-family rentals bought at retail with conventional financing.
• 12%+: excellent. Usually means BRRRR refi, off-market acquisition, or sub-market with rent strength relative to price (parts of the Mon Valley, Beechview, certain Carrick blocks).
• 20%+: double-check the numbers. Either you got an exceptional deal or you are missing an expense line.

How is this different from cap rate?

Cap rate ignores financing - it answers "what would this property yield if I paid all cash?" Cash-on-cash includes your loan, which usually amplifies the return (positive leverage) or destroys it (negative leverage when interest rate > cap rate). For Pittsburgh deals at 2026 rates, cap rates often print in the 6-8% range while CoC can exceed 10% with the right financing - or fall below 4% with the wrong financing.
