Military PCS Home Buying Guide for Southern Maryland: NAS Patuxent River

PCS Guide · NAS Patuxent River · St. Mary's County

PCS orders to NAS Patuxent River bring you to the home of Naval Air Systems Command (NAVAIR) and the Navy's test and evaluation community, in a county surrounded by water on three sides. I help military families buy and sell here every PCS season, and this is the guide I wish every family had the day their orders landed: BAH, on-base vs. off-base, VA loans, where to live off base, schools, and a move-in checklist.

The Base and Its Gates

NAS Patuxent River is the Navy's largest employer in St. Mary's County, with about 2,400 active-duty members, 9,800 civilian employees, and 5,700 contractors, according to Military OneSource. Its major commands include NAVAIR and the Naval Air Warfare Center Aircraft Division.

All three gates come off Route 235 (Three Notch Road), and their hours shape your commute:

• Gate 1 at Pegg Road / Buse Road is the only gate open 24/7.
• Gate 2 at Great Mills Road / Cedar Point Road is open weekdays, 5:30 a.m. to 6:30 p.m.
• Gate 3 at Hermanville Road / Forest Park Road is open only from 6 to 9 a.m.

BAH and Your Housing Budget

Basic Allowance for Housing is set each year by rank, dependency status, and duty location, so always pull your current rate from the official DoD BAH calculator rather than relying on a number from your last PCS. Two tips:

• Lenders typically count BAH as income on your mortgage application, which can help you qualify.
• Budget past your BAH. Your real payment includes property taxes, insurance, and any HOA. St. Mary's County's property tax rate is $0.8478 per $100 of assessed value, so a home assessed at $350,000 owes about $2,967 a year in county tax. Here's how St. Mary's property taxes work.

For context, the Census Bureau's 2020 to 2024 estimate puts the county's median gross rent at $1,747 a month and the median value of an owner-occupied home at $407,600. Those are long-run averages, not today's prices, so ask me for current numbers on the areas you're considering.

On-Base Housing

Family housing on base is privatized and managed by a private partner, with neighborhoods for different ranks and family sizes. If you want on-base housing, contact the Housing Service Center and apply as soon as you have orders, and ask about current wait times for your rank and family size. Even if you plan to buy, knowing the on-base option helps you compare.

Where to Live Off Base Near Pax River

• Lexington Park: right outside the gates, with the shortest commutes and generally the most affordable homes in the county.
• California: the county's main shopping and dining corridor along Route 235, close to Gate 1.
• Great Mills: established neighborhoods near Gate 2.
• Hollywood: more space and a rural feel, a bit farther out.
• Leonardtown: the historic, walkable county seat on Breton Bay, about 20 to 30 minutes from the base.
• Mechanicsville: acreage and quiet in the northern county, with a longer drive.
• Calvert County: Solomons and Lusby sit across the Thomas Johnson Bridge. Drive that commute at rush hour before you commit.

Should You Buy or Rent for a Pax River Tour?

Buying often wins if you'll be here at least a couple of years, your payment lands near your BAH, and you'd be open to keeping the home as a rental when you leave. Renting can make sense on a short tour, if your next move is uncertain, or if you want a few months to learn the area first. I'll run both scenarios with you. If you think you'll rent the home out later, read renting out your St. Mary's home when you PCS.

VA Loan Basics

• 0% down: eligible service members and veterans can finance the full price.
• No monthly mortgage insurance, which can save hundreds of dollars a month compared with a low-down-payment conventional loan.
• Funding fee: a one-time fee, typically 1.25% to 3.3% of the loan depending on your down payment and whether it's your first use. It can be rolled into the loan. Veterans receiving VA disability compensation are exempt.
• Certificate of Eligibility (COE): your lender can usually pull it for you in minutes.
• No VA loan limit with full entitlement: what you qualify for comes down to your income and debts.
• VA appraisal and Minimum Property Requirements: the home must be safe and livable, and a termite inspection is standard in Maryland.

House Hunting From Another Duty Station

Most of my PCS buyers start shopping before they arrive. Here's how we make that work:

• Get preapproved with a VA-experienced lender first, so you can move fast.
• Tell me your gate, your shift, your budget, and your must-haves. I'll send homes that fit, with school assignment, well and septic, flood zone, and drive time checked.
• I'll tour homes for you on live video and give you my honest take on what the camera doesn't show.
• Plan your timeline around your report date. Many local sellers are used to military timelines, rent-backs, and flexible settlement dates.

Schools and Community

St. Mary's County Public Schools serves the whole county with 18 elementary schools, 4 middle schools, and 3 high schools, plus a public charter school, a career and technology center, and a virtual academy. Assignments follow the exact address, so check any home with my guide to St. Mary's school zones. The Interstate Compact on Educational Opportunity for Military Children helps with enrollment and records when kids change schools, and your installation's School Liaison can help before you arrive.

For spouses, the NAVAIR civilian and contractor community means a deeper local job market than most bases this size. Moving here for a civilian job yourself? Read moving to St. Mary's for a NAVAIR or contractor job.

PCS Move-In Checklist

1. Contact the Housing Service Center and decide: on base, rent, or buy.
2. Pull your current BAH from the official calculator.
3. Get preapproved with a VA-experienced lender.
4. Pick your gate and map your commute.
5. Check school assignments for any address you're considering.
6. Schedule inspections, including well water and septic where they apply.
7. Line up homeowners insurance, and flood insurance near the water.
8. Check Maryland MVA rules for your vehicle registration and license. Active-duty members can often keep their home-state registration.
9. Apply for the Homestead Tax Credit once the home is your principal residence.

When It's Time to Leave: Sell or Rent?

When your next orders come, you'll decide whether to sell or keep the home as a rental. Many Pax River owners keep the home as a rental. If you sell, start early, because a home that's ready during PCS season meets buyers with the same urgency you had. See 5 ways to sell your St. Mary's County home faster.

On Base vs. Renting vs. Buying

A PCS Buying Timeline

1. Orders in hand: contact the Housing Service Center, pull your BAH, and call a VA-experienced lender.
2. Early in your window: pick your gate and must-haves, and start getting listings with the local checks done.
3. House hunting: live-video tours or a house-hunting trip, then a strong offer with a settlement date that matches your report date.
4. Under contract (usually 30 to 60 days): inspections, VA appraisal, and loan approval.
5. Before you arrive: line up insurance and utilities, and plan your move-in.

PCS Buying Mistakes to Avoid

• Budgeting off BAH alone and forgetting taxes, insurance, and HOA.
• Picking a neighborhood before checking gate hours for your shift.
• Skipping the well water test and septic inspection on homes without public utilities.
• Buying near the water without a flood insurance quote.
• Not thinking about resale or rentability for when you PCS out.
