Wondering what it really costs to own a home in Germantown each month? Your mortgage is only part of the picture. County property taxes, WSSC water and sewer, and HOA or condo dues can shift your monthly number more than you expect. This guide gives you a simple, local framework to estimate those costs and verify them before you write an offer. Let’s dive in.
What to count in Germantown
Start with a complete list so you do not miss a recurring bill:
- Property taxes for Montgomery County, plus any special district charges
- WSSC water and sewer service
- HOA or condominium dues and any special assessments
- Other utilities: electric, natural gas, trash if not included, Internet/TV
- Homeowners insurance and any escrowed items
This article focuses on the big three in Germantown: property taxes, WSSC, and HOA/condo dues. You will also find quick links for other utilities so your monthly budget is realistic.
Estimate Montgomery County taxes
Your Montgomery County property tax depends on assessed value and the current year’s rate.
- Find the assessed value.
- Look up the property on the Maryland SDAT Real Property Search. Use the owner name, address, or parcel ID to view the most recent assessment. You can start with the SDAT search tool on the SDAT Real Property Search.
- Confirm the current tax rate and any special levies.
- Montgomery County publishes annual real property tax rates and guidance on billing on the Montgomery County Department of Finance website.
- Run the calculation.
- Annual tax = (Assessed value × tax rate) / 100
- Monthly estimate = Annual tax / 12
- Check credits and exemptions.
- Ask the seller for the latest county tax bill and proof of any credits, such as a Homestead Tax Credit. Credits can reduce the taxable assessment. Confirm what applies to you using the SDAT record and county resources.
- Verify before you offer.
- Compare the seller’s last year tax payment to your calculation. Make sure you use the current year’s rate, since it can change annually. Taxes are typically prorated at closing.
Calculate WSSC water and sewer
WSSC serves Germantown, and bills include a base service charge plus usage-based water and sewer charges.
- Pull the property’s actual bills.
- Ask for the last 12 months of WSSC bills to capture seasonal swings. Bills list meter size, gallons used, and total charges. If the seller cannot provide them, request the account number or permission to obtain history from WSSC customer service on the WSSC website.
- Use a simple estimation method if bills are missing.
- Monthly WSSC cost ≈ (meter base charge) + (monthly gallons × water unit rate) + (monthly gallons × sewer unit rate) + fixed surcharges. Rates and fees are posted by WSSC. Usage rises in summer if you irrigate.
- Confirm who pays in your community.
- Some HOAs or condo associations include water and sewer. Check the association budget and your unit’s billing arrangement before you assume this cost.
Verify HOA and condo dues
HOA and condo dues vary widely across Germantown communities based on services and amenities.
- What dues often cover: common-area maintenance, landscaping, snow removal, trash, exterior maintenance, building insurance, reserves, and management.
- Typical Germantown ranges: townhome HOAs are commonly $50 to $300 per month. Condos often range from $200 to $600 or more, depending on amenities and whether utilities are included. Luxury or full-service buildings can be higher. Always verify for the specific property.
- Special assessments: one-time or multi-month charges can be significant. Add the monthly equivalent to your budget if one is scheduled.
How to verify dues and risks:
- Request the current-year association budget, most recent reserve study, and insurance declarations.
- Obtain an estoppel certificate (status letter) that shows current dues, frequency, and any arrears or pending assessments.
- Review the last 6 to 12 months of meeting minutes for upcoming projects or litigation. For general guidance on association documents and best practices, visit the Community Associations Institute.
Other monthly utilities
Round out your monthly budget with expected utility costs. Always prefer actual bills when available.
- Electric: Pepco serves most of Montgomery County. Check service and programs with Pepco.
- Natural gas: Many homes use Washington Gas. Confirm availability and get usage history from Washington Gas.
- Trash and recycling: Many single-family homes receive county service. Review schedules and any fees via Montgomery County Solid Waste Services. In many condos and HOAs, trash is included in dues.
- Internet/TV: Major providers in Germantown include Xfinity and Verizon Fios. Plan costs vary by speed and bundle.
- Insurance: Get a quote tailored to the home’s size, age, and coverage level. If you escrow insurance with your lender, include it in your monthly total.
