Quick answer: Two Pennsylvania features decide the money. Closing is expensive: a 1% state realty transfer tax with local tax commonly on top, bringing many municipalities to around 2% and Philadelphia considerably higher. Assessment is indirect: counties assess on irregular base years, and the State Tax Equalization Board publishes an annual Common Level Ratio per county to reconcile assessed values with market. The CLR can set your transfer-tax base — the tax applies to the greater of consideration or assessed value × CLR factor — and it is the arithmetic at the centre of any assessment appeal.

Get My QuotePennsylvania is the state where the assessed value on the record may mean almost nothing on its own. Counties reassess on their own irregular schedules, sometimes decades apart, so a raw assessment can be wildly out of step with what a property is worth. The state's answer is a ratio published every year to translate between the two — and that ratio quietly shows up in your closing costs and in any appeal you ever file.
Key takeaways
- State realty transfer tax is 1%, with local taxing bodies commonly adding their own — often ~2% combined, Philadelphia considerably higher.
- Counties assess on irregular base years, so assessed value alone is not a market figure.
- The Common Level Ratio reconciles them, published annually per county by the State Tax Equalization Board.
- Transfer tax applies to the greater of actual consideration or assessed value × CLR factor.
- The CLR is central to assessment appeals — it is applied to a finding of current market value to set the assessment.
- Which year's factor applies matters, because the figures are republished annually.
- Philadelphia is its own exercise on both transfer tax and rental licensing.
The base-year problem
Most states assess property against something close to current market value on a defined cycle. Pennsylvania counties assess against a base year, and they choose when to conduct one. Some counties have gone a very long time between reassessments.
The consequence is that a Pennsylvania assessed value, read on its own, tells you little. It is a figure expressed in the currency of whatever year that county last reassessed. Two properties of identical present value in neighbouring counties can carry assessed values that are not remotely comparable, because the base years differ.
For an investor this is mostly a warning against a specific shortcut: do not infer a Pennsylvania property's market value, or your likely tax exposure, from the assessed value without knowing the county's base year and its current Common Level Ratio.
The Common Level Ratio
The Common Level Ratio is Pennsylvania's translation device. Calculated by the State Tax Equalization Board from sales data and published each year for every county, it represents the average relationship between assessed values and market values in that county. A factor derived from it converts an assessed figure into present-day terms.
Two things follow that matter to a buyer. It appears on the realty transfer tax affidavit, where both the assessed value and the CLR factor are reported. And it is republished annually, so the applicable factor depends on timing rather than being a fixed county attribute.
The closing cost, and how the CLR can set it
Pennsylvania imposes a 1% state realty transfer tax on the value of real estate transferred by deed. Local taxing bodies commonly impose their own realty transfer tax as well, which in many municipalities brings the combined burden to around 2%. Philadelphia's combined rate is substantially higher.
On a $400,000 purchase, a 2% combined rate is roughly $8,000 — illustrative, on a round number, and dependent entirely on the municipality. Set that against Colorado, where the state-level cost on the same purchase is about $40, and the range across states becomes obvious.
Where a transfer is not exempt, the tax is calculated on the greater of the actual consideration or the product of the assessed value and the CLR factor. In an ordinary arm's-length purchase your price is normally the larger figure and therefore the base. The rule bites on below-market or non-arm's-length transfers, where the CLR-derived value can exceed what changed hands — a point worth raising with counsel if you are moving property between related parties or into an entity. Our entity-vesting page covers why transfers into an LLC deserve tax advice before they are recorded.
Appeals, and why the CLR decides them
If you think a Pennsylvania assessment is wrong, the CLR is the arithmetic you will be working inside. On appeal, the CLR is applied to a determination of the property's current fair market value in order to set its assessment — the intent being that the result stays uniform with the county's base-year assessments rather than singling your property out.
Practically, that means a successful appeal is not an argument that your assessment is high in absolute terms. It is an argument about market value, which the CLR then converts. And because a lower assessment lowers the tax line inside PITIA, it raises your DSCR — which matters if a refinance is in your plan. You can size that effect on the calculator by lowering the tax input.
Philadelphia
Philadelphia deserves separate treatment on two grounds. Its combined realty transfer tax is materially above the typical Pennsylvania municipality, so cash-to-close on a city purchase is meaningfully heavier. And the city operates rental licensing requirements that determine whether a property may lawfully be rented at all.
That second point is a timing risk rather than only a cost: a property you cannot lawfully rent yet produces no income while the loan is outstanding. It is the same shape of problem Michigan's municipal rental registration presents, and the same fix — confirm the requirement with the city before closing.
Getting the Pennsylvania file right
- Get the combined transfer tax rate for the specific municipality, not a statewide figure.
- Ask the county for its base year and the current CLR factor before drawing any conclusion from an assessed value.
- Confirm municipal rental licensing, especially in Philadelphia, before closing.
- Quote insurance on the address and confirm any association dues.
- Get tax advice before any non-arm's-length transfer, including into an entity.

DSCR loans in Pennsylvania: FAQ
How does Pennsylvania decide what my property is worth for tax?
Through a system unlike anything else in this cluster. Pennsylvania counties assess on irregularly-conducted base years — some counties have not reassessed in a very long time — so a raw assessed value can bear little relation to current market value. To reconcile them the State Tax Equalization Board publishes a Common Level Ratio for each county every year, representing the average relationship between assessed and market values there. The CLR is how assessed figures get translated into present-day terms.
What is the realty transfer tax in Pennsylvania?
The state imposes a realty transfer tax of 1% on the value of real estate transferred by deed, and local taxing bodies commonly impose their own on top — in many municipalities that brings the combined figure to around 2%, and Philadelphia is substantially higher. Confirm the combined rate for the specific municipality with your closing agent, because the local half varies considerably.
Is the transfer tax charged on my purchase price?
Usually, but not always — and this is where the Common Level Ratio reappears. Where a transfer is not exempt, the tax is based on the greater of the actual consideration for the transfer or the product of the assessed value and the county's CLR factor. So on a below-market or non-arm's-length transfer, the CLR-derived figure can exceed what you actually paid and become the taxable base. For an ordinary market purchase the consideration is normally the higher number.
Why does the Common Level Ratio matter to an investor?
Two reasons. It can set your transfer-tax base at closing, as above. And it is central to assessment appeals: on appeal the CLR is applied to a determination of current fair market value to set the assessment, so that the result is uniform with the county's base-year assessments. If you believe a Pennsylvania assessment is wrong, the CLR is the arithmetic you will be arguing within. Because it is republished annually, which year's factor applies matters.
What are the DSCR loan requirements in Pennsylvania?
Standard: non-owner-occupied, genuinely business-purpose, rent covering the full monthly housing cost, plus credit, reserves and entity documentation. Common practice is around 20–25% down with three to six months of PITIA in reserves. Pennsylvania's distinctive features are the closing-cost level and the base-year/CLR assessment machinery, not the underwriting.
Is Philadelphia different?
Materially, on both cost and compliance. Philadelphia's combined realty transfer tax is substantially above the typical Pennsylvania municipality, and the city operates its own rental licensing requirements that gate whether a property may lawfully be rented. Treat a Philadelphia purchase as its own diligence exercise rather than a Pennsylvania one, and confirm licensing requirements before closing rather than before your first tenant.
Does Pennsylvania have rent control?
Pennsylvania does not impose statewide rent control. Municipal licensing and inspection requirements, however, are real and vary by city, and they can affect whether and when you can rent. Confirm the municipal position for the specific address.
The bottom line
Pennsylvania asks for more at the closing table than most states and gives you an assessment system you cannot read at face value. Get the municipality's combined transfer rate before you model cash-to-close, get the county's base year and CLR factor before you infer anything from an assessed value, and treat Philadelphia as its own exercise on both cost and licensing.
If you have an address in view, send us the property and the expected rent and a loan officer will run the ratio on the numbers that will actually apply to you.
