Every ZIP code has its own selling season. This shows how yours actually behaves — how fast the market moves month by month, when asking prices run highest, and when you’ll face the most competition — from ten years of Maryland listing data.
The other half is the number. See what your home is likely worth today, then we can talk about when it makes sense to list it.
Days on market. The median time listings in your ZIP code had spent on the market during each calendar month, averaged across ten years. It measures how fast the market is moving in that month — not how long your particular home would take.
Asking prices. Each month compared against that ZIP code’s own annual average, so 103 means asking prices in that month run about 3% above the yearly norm. Comparing a ZIP against itself keeps expensive areas from swamping the pattern.
Competition. New listings that month, again against that ZIP code’s annual average. The busiest months bring the most buyers and the most rival listings at the same time.
The data. Realtor.com® residential listing inventory, 2017 through 2026, covering 279 Maryland ZIP codes with a full year of history. April 2020 through June 2021 is excluded — that market was not a normal season and would distort every month it touched. ZIP codes without enough history fall back to the statewide pattern.
This is a pattern, not a promise. Season is one input among many: your price, your condition, your street, and what else is for sale that week all matter more. Mortgage rates can override the calendar entirely. Use this to inform the conversation, not to replace it.
