Feeling lost in those monthly Dorchester market reports? You are not alone. The numbers move fast and each block can tell a different story. With a few key concepts, you can read the stats with confidence, spot real opportunities, and avoid common traps. This guide breaks down the core metrics and shows you a simple framework you can use every month. Let’s dive in.
Start with the headline numbers
Begin with a quick scan to see where the market is trending. Look for:
- Median sale price and its year-over-year change
- Active inventory and how it moved month over month and year over year
- Median days on market (DOM)
- Months of inventory or absorption rate
- Number of closed sales and pending sales
- Sale-to-list ratio
These headline figures set the tone. Then you can drill down by property type and street-level pockets.
What each metric means
Inventory
Inventory is the count of homes actively listed at a point in time. Some reports also show inventory as months of supply. Expect variation across Dorchester’s product types. Condos, single-families, and multi-family triple-deckers follow different rhythms.
Common pitfalls:
- Duplicate or stale listings can make counts look higher than they are.
- Small counts in a micro-area can create misleading percentage swings.
Reading tip: Track both the raw active count and months of inventory to understand supply pressure.
Days on Market (DOM)
DOM measures the time from list date to accepted offer or to closing, depending on the dataset. Median DOM is usually the better gauge because it reduces outlier effects.
Common pitfalls:
- Relisting can reset DOM, which understates true market time.
- Make sure you know whether the report uses DOM to contract or DOM to close.
Reading tip: Short median DOM with rising prices often signals strong demand. Longer DOM with flat or falling prices can point to oversupply or pricing mismatches.
List-to-sale ratio
The list-to-sale ratio is the sale price divided by the final list price, expressed as a percentage. It shows how close sellers are getting to their asking price.
How to read it:
- Above 100 percent suggests competitive bidding.
- Around 98 to 100 percent indicates a balanced feel.
- Below 98 percent signals more room for negotiation.
Note: This ratio does not include off-market credits, repairs, or concessions.
Price per square foot (PPSF)
PPSF is the sale price divided by finished living area. It is best for comparing similar properties within a narrow class such as two-bed condos in the same building.
Cautions:
- Living area definitions can vary across sources.
- PPSF is not reliable for comparing condos to multi-family or single-family homes.
- PPSF ignores lot value, basements, ceiling heights, and finish quality.
Use PPSF as a quick cross-check, not a primary pricing tool across different property types.
Absorption and months of inventory
Absorption tells you how fast homes are selling relative to supply. Months of inventory equals active listings divided by average monthly sales.
Industry conventions:
- Less than 3 months is a seller’s market.
- 3 to 6 months is balanced.
- More than 6 months is a buyer’s market.
Cautions:
- Short time windows create volatility at the micro level.
- Separate new listings from relistings and account for pending sales to avoid double counting.
Read Dorchester by micro-market
Dorchester is not one market. Product mix and location shape the stats.
Condo-heavy corridors
Areas near Dorchester Avenue, Andrew Square, and Fields Corner tend to show more condo inventory and attract many first-time buyers. Expect quicker shifts in list-to-sale ratios as new buildings release units.
Single-family pockets
Savin Hill, Lower Mills, Port Norfolk, and Neponset include pockets of single-family homes and townhouses. PPSF and DOM here can differ from condo corridors due to lot sizes, home age, and renovation levels.
Transit-oriented multi-family
Ashmont and Peabody Square have a higher share of multi-family stock with walking access to the Red Line. Investor interest can move absorption and list-to-sale ratios differently than in owner-occupied areas.
Takeaway: Compare only like with like. Same property type, similar condition, and nearby location are key.
A simple step-by-step framework
First pass: direction check
- Check median sale price year over year.
- Look at active inventory and how it shifted month over month and year over year.
- Scan median DOM.
- Review months of inventory or absorption.
- Note closed sales and pending counts.
- Check the list-to-sale ratio.
Second pass: break it down
- Split by property type: condos, 2 to 3 family, single-family, townhouses.
- If sample size allows, zoom in by station area or street clusters.
- Cross-check pending versus closed. Rising pendings with falling inventory can signal short-term tightening.
- Compare new listings to canceled or withdrawn listings. A spike in cancellations suggests pricing gaps.
Data quality checks
- Be cautious when there are fewer than about 10 closed sales in a micro-area.
- Watch for outliers like a single luxury sale that can skew medians.
- Use 3 or 6 month rolling averages to smooth noise.
Context and project flags
- New construction or a large condo conversion can shift PPSF and inventory.
- Building-level sales in a marquee project can skew a neighborhood’s PPSF.
- Track local zoning or development news that may add future supply.
How to combine metrics for real signal
- High PPSF plus low DOM plus low inventory: strong demand for that niche, often a seller’s market.
- Rising inventory plus rising DOM plus falling list-to-sale: softening demand or over-pricing. Buyers may be gaining leverage.
- Low inventory but falling PPSF or list-to-sale: active stock may be lower quality or demand may be shifting by price band.
- High PPSF in a small area while the broader area is flat: a local premium tied to transit or new amenities.
Seasonality and trend reading
Greater Boston is seasonal. Spring tends to bring the most listings and sales, while winter slows down. Because of this, compare month-over-month numbers with care and always include year-over-year context.
- Use rolling 3 or 6 month views to find true direction.
- If a report covers a short period with only a few sales, assume higher volatility.
- When you quote a stat, include the reporting period and, if possible, the sample size.
What this means for you
If you are selling
Focus on days to offer, list-to-sale ratio, and the closest comps on your street or in your building type. If months of inventory is under 3 for your property class and median DOM is short, pricing near market value and strong presentation can trigger early activity. Professional staging, repairs, and high-quality visuals help you stand out when buyers are moving fast.
If you are buying
Watch absorption and pending activity. If list-to-sale ratios sit below 98 percent and DOM is climbing, you may have room to negotiate or ask for credits. In hot niches where ratios top 100 percent, expect competitive terms and have financing and timelines ready.
If you are investing
Look at months of inventory and absorption for multi-family stock, but do not stop there. Cross-check rental demand, unit mix, and condition. In areas near transit, small shifts in quality or renovation level can swing PPSF and cap assumptions.

FAQs
How should a first-time buyer use DOM in Dorchester?
- Treat median DOM as a speedometer. Short DOM suggests quicker decisions and stronger offers, while longer DOM can allow more negotiation and due diligence time.
Is price per square foot useful across different property types?
- Use PPSF only within the same property type and similar condition. Do not compare condos to multi-family or single-family homes using PPSF alone.
What signals a good time to list in Dorchester?
- Low months of inventory under 3, rising pending sales, short median DOM, and list-to-sale ratios at or above about 99 percent are favorable signals for sellers.
Why do monthly medians jump in small areas?
- Small sample sizes and one-off high or low sales can move medians. Use rolling averages and check how many sales are included.
How do investors read months of inventory for multi-family?
- Low months of inventory can show strong buyer demand, but investors should also review rental demand, unit mix, renovation scope, and expected cash flow.
