How to Look Up Montgomery County Real Estate Records (Property, Tax, and Sales)

Montgomery County real estate records are public. You can look up any property's ownership history, assessed value, tax bill, lien status, and recent sale price — for free, in about two minutes — if you know where to go. Most people don't know where to go. Here's the complete guide.

The Three Sources You Need

There are three separate systems for Montgomery County real estate records, and each shows something different:

| Source | What It Shows | Best For | |---|---|---| | SDAT (Maryland State) | Ownership, assessment history, property details | Tax basis, who owns a property | | MC Finance Office | Tax bill, payment history, account balance | Tax records, whether taxes are paid | | County land records | Deed, liens, mortgage, sale price | Sales history, encumbrances |

You often need more than one source to get the full picture.

1. SDAT: Property Records and Assessment History

Maryland State Department of Assessments and Taxation (SDAT) maintains the statewide property database. This is the primary source for:

• Current owner name and mailing address
• Assessed value (what the county uses to calculate your tax bill)
• Assessment history going back multiple cycles
• Property characteristics (square footage, year built, lot size)
• Exemptions and credits applied

How to search: Go to SDAT's online real property search. Search by address, account number, or owner name. Results are free and immediate.

The "Assessment" tab shows the current full cash value and assessed value, plus the history of previous assessments. This is what you need if you're considering an appeal or want to verify a tax calculation.

Important note: SDAT assessment values are not the same as current market value. Maryland reassesses on a triennial (3-year) cycle, so assessed value often lags behind what the market actually says a home is worth — sometimes significantly.

2. Montgomery County Finance: Tax Records and Payment Status

The Montgomery County Finance Office portal shows your actual tax bill and payment history. This is what you need for:

• Current year tax amount owed
• Whether taxes are paid or delinquent
• Payment history for prior years
• Account balance and any outstanding interest

How to search: Search the MC Finance real property tax portal by address or account number. You can view the current bill, see if payments have been made, and download prior year statements.

This is the source to check when buying a property to verify there are no delinquent taxes. Unpaid property taxes become a lien on the property and transfer with the deed — meaning you could inherit them at closing if not caught in title review.

Tax sale list: Properties with delinquent taxes for two or more years appear on the county's tax sale list, which is publicly available. If a home you're considering is on this list, it's a red flag that needs resolution before closing.

3. Land Records: Deeds, Sales Prices, and Liens

Maryland land records are maintained at the Circuit Court level. For Montgomery County, the land records office holds:

• Deed history (chain of title — every recorded ownership transfer)
• Sale price for every recorded transaction
• Mortgage documents (shows loan amounts, lenders)
• Liens (mechanics liens, judgment liens, HOA liens)
• Plat maps and easements

How to search: The Maryland Land Records online database (mdlandrec.net) provides free access to recorded documents. Search by name, address, or instrument type. Documents are scanned images of the actual recorded paperwork.

Sale price: Maryland does not require sellers to disclose the sale price separately, but the consideration (sale price) is listed in the deed document and the transfer/recordation tax stamps on the deed allow you to back-calculate it. The state transfer tax is 0.5% of the sale price, so if you see a $3,000 transfer tax stamp, the sale price was $600,000.

Alternatively, sale prices appear on the SDAT record after the transaction is processed — usually within a few weeks of closing.

How to Find What a Neighbor's House Sold For

This is the most common reason people search real estate records.

Option 1 (quickest): Check SDAT. Search the neighbor's address, go to the "Transfer" or "Sales" tab, and the recorded sale prices and dates appear there.

Option 2 (most detail): Search Maryland Land Records for the address. Find the most recent deed. The deed will show the grantee (buyer), grantor (seller), date, and the transfer tax stamps that reflect the sale price.

Option 3 (easiest interface): Use a real estate portal like Zillow or Redfin — they aggregate this data and display it clearly. These are not official government sources but they pull from the same underlying records and are usually accurate for recent transactions.

Montgomery County Real Estate Records: Common Use Cases

Buying a home: Before making an offer, pull the SDAT record (assessment history, property details), the Finance record (no delinquent taxes), and the land records (no surprise liens or easements). Your title company will do a full title search at closing, but checking yourself first costs nothing and surfaces problems early.

Appealing your assessment: SDAT is your starting point. Pull your assessment history, compare it to recent sales of comparable properties in your area, and use that data to build your appeal. The Maryland Tax Court accepts evidence of recent comparable sales.

Researching a neighborhood: Pull recent sales from SDAT or land records for your target street or zip code to understand actual transaction prices — not just list prices.

Verifying a seller's claim: If a seller says they made $150,000 in renovations, check the permit history through Montgomery County's permit portal, and cross-reference against the SDAT assessed value change after the improvements.
