What are the Philadelphia Market Competition Charts?

These two charts help show the overall competitive landscape for rentals in Philadelphia.

The chart on the left tracks Philadelphia average apartment monthly rent. The chart on the right tracks total Philadelphia on-market rentals.

Together, they help show both sides of the market: price and supply.

Chart 1: Philadelphia Average Apartment Monthly Rent

This chart shows the average Philadelphia apartment rent as reported by Apartments.com.

Otter Property Management captures this data every month so you can see how Philadelphia rents are moving over time.

This chart is best used to identify trends. It helps you see:

Year-over-year rent movement.
Seasonal patterns in rent pricing.
Whether the overall tide of Philadelphia rents is rising, flattening, or falling.

That matters because it gives property owners context for pricing and renewals. If the broader market is pushing upward, landlords usually have more leverage. If rents are flattening or softening, pricing decisions may need to be more conservative.

This chart is less about one exact number and more about the direction of the market over time.

Chart 2: Total Philadelphia On-Market Rentals

This chart shows the total number of rental units currently on the market in Philadelphia County based on Zillow search results.

Otter Property Management captures this data every month so you can track how much rental supply is currently competing for tenants.

This chart helps show the competition level in the market.

More units on the market usually means more competition for tenant attention. That can create downward pressure on pricing and make leasing more competitive.

Fewer units on the market usually means less competition. That can create upward pricing pressure and strengthen landlord leverage.

This is a useful supply-side chart because it helps answer a simple question: how crowded is the rental market right now?

Why these charts are useful together

These charts are most useful when read together, not separately.

The average rent chart helps show what the market is doing on the price side.

The on-market rentals chart helps show what the market is doing on the supply side.

When you combine them, you get a much better sense of overall market conditions.

If rents are rising while on-market inventory is falling, that usually points to a tighter market and stronger landlord leverage.

If on-market inventory is rising while rents are flattening or falling, that usually points to a softer market and weaker pricing power.

If inventory is rising but rents are still rising too, that can suggest demand is still absorbing the added supply.

What these charts help you understand

These charts help owners and investors better understand:

How competitive the Philadelphia rental market is.
How much pricing leverage they may have.
How current conditions compare with the same month last year.
Whether the market is getting tighter or softer over time.
How to think about renewal strategy, asking rent, and leasing expectations.

They are especially useful for year-over-year comparisons. Looking at one March in isolation is less helpful than comparing that March to prior March results.

What these charts are and are not

These charts are broad market indicators.

They are useful for understanding trends, seasonality, and competitive pressure.

They are not a perfect pricing tool for one specific unit.

They are not a substitute for looking at your property’s neighborhood, condition, size, features, and target tenant profile.

In other words, these charts help explain the market backdrop, but they should still be paired with property-specific analysis.

Bottom line

The Philadelphia Market Competition Charts help show the overall rental environment in Philadelphia from two important angles: rent levels and active supply.

The Philadelphia average apartment monthly rent chart shows the broader pricing trend over time.

The total Philadelphia on-market rentals chart shows how much competition is currently on the market.

Together, they help property owners understand market leverage, pricing pressure, and leasing strategy in a clearer and more practical way.
