The Real Expense Ratio on a York County 2-4 Unit

In real estate investing forums and books, the "50% rule" gets cited often: assume that 50% of gross rent goes to operating expenses. It's a useful shorthand for back-of-envelope deal screening, but on a typical York County 2-4 unit rental, the real ratio runs 35-45% — not 50%.
The gap matters. A 5-10% difference in expense ratio on a property earning $40,000 of gross rent is $2,000-$4,000 per year of NOI, and it cascades into 10-15% differences in the price a buyer can pay at the same cap rate.
This piece walks through the actual line items that make up a 2-4 unit's operating expense load in York County in 2026, with realistic ranges for each, and explains where the 50% rule comes from and why it overstates for this property type.
The line items on a 2-4 unit
Operating expenses on a small multifamily fall into seven categories. Each one varies with the property; together they produce the expense ratio.
1. Property taxes (~12-18% of gross rent).
For a typical York County 2-4 unit assessed in line with its market value, property taxes run roughly $2,500-$5,500/year on a $150K-$300K assessment depending on borough and school district. As a percentage of gross rent (say $30K-$45K), that's 12-18%.
2. Insurance (~3-5% of gross rent).
Landlord insurance on a 2-4 unit in York County runs $1,200-$2,200/year depending on coverage and property age. As a percentage of gross rent, 3-5%.
3. Repairs and maintenance (~5-10% of gross rent).
Year-to-year maintenance — appliance repairs, plumbing, minor electrical, paint touch-ups, lawn care, snow removal — runs roughly 5-10% of gross rent. The lower end for a recently-updated property, the higher end for an older property with deferred maintenance.
This is the line item that owners chronically under-track. Maintenance happens unevenly — three quiet years followed by a year with a $4,000 plumbing event — and sloppy tracking creates the illusion of low expenses one year and high expenses another. Average it across 5 years and 5-10% is the realistic band.
4. Vacancy and re-leasing (~3-7% of gross rent).
Even a stable 2-4 unit has tenant turnover that creates vacant weeks and re-leasing costs (advertising, screening, make-ready). The actual cost varies with how long turnover gaps run and how aggressive the landlord is with make-ready spend. 3-7% is the realistic band.
5. Property management (~8-10% of gross rent if used).
If a landlord uses a professional manager, the fee typically runs 8-10% of collected rent plus turnover/leasing fees. Many self-managing landlords don't include this line — but it should still be on the underwriting because it represents what the next owner would pay (or what the current owner is implicitly paying themselves in time).
6. Utilities paid by landlord (~0-8% of gross rent, varies wildly).
Some 2-4 unit configurations have landlord-paid utilities (master-metered water, common-area electric, garbage collection). Others put everything on tenants. This line is highly property-specific.
7. Capital reserves (~5-10% of gross rent).
Capital reserves aren't strictly "operating expenses" in accounting terms — they're below-the-line capital items — but for the real expense ratio (the one that drives sustainable cash flow), capex reserves should be included. Roof, HVAC, kitchen/bath renovations, exterior paint, structural repairs.
5-7% is typical for a recently-updated property; 8-12% for an older property where capex catches up faster.
Adding it up
For a typical York County 2-4 unit with $40,000 gross rent, in 2026 conditions:
Property taxes
Range (% of gross): 12-18%
Dollar range: $4,800-$7,200
Insurance
Range (% of gross): 3-5%
Dollar range: $1,200-$2,000
Repairs/maintenance
Range (% of gross): 5-10%
Dollar range: $2,000-$4,000
Vacancy
Range (% of gross): 3-7%
Dollar range: $1,200-$2,800
Management (if used)
Range (% of gross): 8-10%
Dollar range: $3,200-$4,000
Utilities (varies)
Range (% of gross): 0-8%
Dollar range: $0-$3,200
Capex reserves
Range (% of gross): 5-10%
Dollar range: $2,000-$4,000
Total range
Range (% of gross): 36-58%
Dollar range: $14,400-$23,200
The total band runs 36-58%. Most properties cluster in the 38-45% range when run honestly with all line items present.
Where the 50% rule comes from and why it overstates here
The 50% rule originated with larger multifamily underwriting (10+ units, urban Class C properties), where utility costs and management costs are typically higher relative to rent, and where the property tax base is more aggressive. For those property types, 50% is a reasonable shorthand.
For York County small multifamily — fewer units, often self-managed, often with tenant-paid utilities — the rule overstates. Property tax loads aren't as compressing as in NYC or San Francisco. Management is often DIY at the small-property level. Utility configurations vary but more units have tenant-paid setups than landlord-paid.
The honest band for York County 2-4 unit rentals in 2026 is 35-45% expense ratio, with 40% as a reasonable midpoint for sale underwriting.
Why this matters at sale time
When a buyer is underwriting your 2-4 unit, they're applying their own expense ratio assumption to your gross rent. If the buyer assumes 50% (the rule of thumb), they're producing a lower NOI estimate than the property actually generates — and their offer reflects the lower NOI.
If you can show a serious buyer that the property's actual expense ratio is 40% (with line-item documentation), the buyer's NOI estimate goes up by 10% of gross rent. On $40K of gross rent, that's $4K of NOI. At a 7.5% cap rate, that's $53K of additional value the buyer can support.
The line-item documentation matters. A buyer or appraiser won't take "trust me, my expenses are low" — they'll want to see the trailing 12 months of actual receipts and bills, year over year, with clean categorization.
What sellers should track to get full credit at sale
Three habits make a small multifamily's expense ratio defensible:
1. Monthly expense logging. Even a simple spreadsheet with date, category, amount, vendor. Doesn't need to be QuickBooks-polished — just complete.
2. Receipt retention. Physical or digital. 5-7 years of receipts is the standard. Buyers usually only ask for the last 12-24 months, but the longer history confirms the pattern is real.
3. Capital reserves discipline. Either a separate account that you actually fund, or — at minimum — a documented record of capital expenditures over the hold period. Owners who can show "I spent $18K in capex over 8 years" have more credibility on capex reserves than owners who can show $0 of capex.
These habits make a sale price 5-15% higher than the same property without the documentation. Worth more than the small ongoing cost of maintaining the records.
A direct option in York County
I'm Ed Lane, a local buyer in York County actively buying 2-4 unit rental properties directly from owners. The expense ratio review is one of the first underwriting steps I run on any property — using the actual line-item history rather than rule-of-thumb shortcuts. Sellers with documented expense history get fair credit; sellers without it don't pay for the gap, but the offer reflects what's verifiable.
