After funding over 4,000 real estate deals since 2007, I’ve seen one number kill more Maryland flips than any other: a poorly calculated ARV. The ARV (After Repair Value) isn’t just another metric. It’s the foundation that determines how much the property will resell for, how much you can borrow from a lender, and ultimately whether you’ll make money or not. If you’re trying to understand how to calculate ARV in Maryland so you’re deals get funded, here are some things you should know.

In Maryland’s diverse markets, from Baltimore’s historic rowhomes to Prince George’s County’s suburban sprawl, calculating the ARV requires local knowledge that generic formulas often overlook. The same renovation that adds $50,000 in Bethesda might add $15,000 in West Baltimore. That’s not a theory. That’s reality backed by thousands of deals I’ve underwritten over the past decade and a half.

This guide breaks down the exact process I use to evaluate ARV when deciding whether to fund a deal. You’ll learn the step-by-step calculation method, see real Maryland examples with actual numbers, and discover the mistakes that get loan applications rejected.

What is ARV and Why it’s so important to Real Estate Investors and Lenders

The ARV represents the estimated market value of a property AFTER all renovations are complete. It’s not what you paid plus what you spent. It’s what a new homebuyer will actually pay for your finished house. This matters to your profit margins and to hard money lenders like us, who base our loan amounts on the ARV.

Here’s the reality: I’ll lend up to 65-70% of a property’s ARV. If your ARV is $350,000, my maximum loan amount is approximately $227,500 to $245,000. That should cover funds towards the purchase and renovation costs. Get the ARV wrong, and it will eat into your project margins, or even worse, you could lose money on your investment.

The calculation itself isn’t complex. You find recently sold, renovated properties (comparables or comps) similar to what yours will become, adjust for differences, and arrive at a defensible value. The challenge lies in the execution. Maryland’s hyper-local markets mean a comp from two blocks away might be worthless. A finished basement adds significant value in Bowie but means less in a Canton rowhome.

Traditional banks don’t love these deals. They tend to lend on current value, which for a distressed property might be next to nothing. Hard money lenders fund based on future value, which is why ARV accuracy determines everything.

The Step-by-Step ARV Calculation Process

Step 1: Find the Right Comparable Properties

Start by identifying 3-6 properties that sold within the last 30-90 days, ideally (you can go back a little further if needed). These comps must match your subject property’s planned post-renovation state, not its current condition. In Maryland, this means being extremely specific about location and property type.

For Baltimore rowhomes, stay within a 0.25-mile radius, ideally on the same block. The difference between the north and south sides of the same street can be $50,000. For PG County properties, you can expand a little further but stay within the same school district. A property in the Bowie High district commands different prices than one zoned for Bladensburg.

Your comps should have similar square footage (within 15%), the same number of bedrooms and bathrooms after renovation, and comparable lot sizes. Don’t compare a rowhome to a detached house. Don’t compare a 1920s property to new construction unless you’re planning a museum-quality restoration.

Access your Multiple Listing Service (MLS) through a licensed professional, who can help you pull accurate comps. Public sites like Zillow work for initial research, but verify everything against actual sale records. You can also access public records through your county’s assessment office.

Step 2: Adjust for Location Differences

Baltimore neighborhoods change dramatically block by block. A renovated rowhome in Patterson Park might sell for $400,000, while an identical renovation three blocks into a more price point area struggles to break $250,000. I’ve seen investors lose six figures by using comps from the “wrong” side of North Avenue.

In PG County, proximity to Metro stations drives premiums. A property walking distance from the Greenbelt station commands 15-20% more than one requiring a car. School ratings create similar gaps. Properties zoned for highly rated elementary schools in Bowie or Upper Marlboro significantly outperform those in struggling districts.

Don’t guess at these adjustments. Track actual sales data. If homes on quiet streets sell for $20,000 more than those on busy roads, that’s your adjustment. If properties with parking consistently beat those without by $30,000 in Federal Hill, factor it in.

Step 3: Account for Planned Renovations

Not all improvements create equal value. Based on thousands of Maryland flips I’ve funded, here’s what actually moves the needle:

Kitchen renovations return the highest ROI, but only to a point. A mid-range kitchen remodel, costing $30,000, typically adds $25,000-$ 35,000 in value. Spend $75,000 on high-end appliances and imported marble? You might add $40,000 in value. The market has ceilings.

Bathrooms follow similar rules. Adding a second full bath to a one-bathroom rowhome can add $25,000 to $30,000 in value. Upgrading an existing bathroom might add $15,000-20,000. In Maryland’s older housing areas, functional improvements consistently outshine luxury finishes.

Finished basements work differently in Maryland than elsewhere. In suburban PG County, a finished basement adding 600 square feet of living space might increase value by $30,000-40,000. In a Baltimore rowhome where basements are often damp and low-ceilinged, the same investment might add $10,000.

Step 4: Calculate Your ARV

Once you have adjusted comps, calculate the average to establish your baseline ARV. Then apply a conservative discount. I recommend using the lower of: the average of your three lowest comps, or 95% of your calculated average. This buffer protects against market shifts and appraisal variations.

Here’s the CRITICAL part: your ARV must be defensible to an appraiser. If you claim $400,000 but every comp requires aggressive adjustments to reach that number, you have a problem. The appraiser hired by your lender won’t share your optimism.

Example Maryland Case Studies

Baltimore Rowhome Flip – Canton Neighborhood

Let’s walk through an example loan. The property is a 2-bedroom, 1.5-bath row home in Canton, measuring 1,400 square feet, and is listed for $225,000.

There are three solid comps within four blocks, all renovated and sold within 90 days: – 618 S Belnord Ave: 3 bed, 2 bath, 1,408 sq ft, sold for $369,000 – 804 S Highland Ave: 2 bed, 3 bath, 1,734 sq ft, sold for $400,000 – 2902 Hudson St: 2 bed, 2.5 bath, 1,476 sq ft, sold for $375,000

After adjustments for the bedroom/bathroom differences and calculating price per square foot ($249 average), the investor projected a $360,000 ARV. They planned $100,000 in renovations, including a kitchen remodel ($30,000), bathroom addition ($25,000), and a complete systems update.

Using the 70% rule: ($360,000 x 0.70) – $100,000 = $152,000 maximum allowable offer. The $225,000 purchase price was way too high. The investor needed to renegotiate or walk away. They walked. Smart move.

Prince George’s County Suburban Flip – Bowie

Here’s a successful PG County project. A 3-bed, 2-bath rambler in Bowie, 1,800 square feet, purchased for $310,000 (negotiated down from $350,000 asking).

The comps from the same subdivision: – 2627 Kennison Ln: 3 bed, 2 bath, 2,018 sq ft, sold for $525,000 – 12011 Twin Cedar Ln: 3 bed, 2 bath, 1,583 sq ft, sold for $484,000 – 2902 Stonybrook Dr: 3 bed, 2.5 bath, 1,800 sq ft, sold for $450,000

Conservative ARV calculation came to $475,000. The investor budgeted $75,000 for renovations, with a focus on kitchens, bathrooms, and curb appeal. With a 10% contingency, the total rehab budget was $82,500.

The 70% rule math: ($475,000 x 0.70) – $82,500 = $250,000 maximum offer. The negotiated price of $310,000 still left tight margins, but the investor had strong experience and cash reserves. If a lender funded it at 80% of the purchase price and 100% of rehab, the real estate investor would probably net $42,000 profit after all costs.

Costly Mistakes Maryland Investors Make

After reviewing thousands of Maryland ARV calculations, these mistakes appear constantly:

Using comps from different jurisdictions. Montgomery County prices don’t apply to PG County. Anne Arundel comps don’t work for Baltimore County. In both of these examples the counties overlap so make sure you are only reviewing property comps in the same county. Each jurisdiction has different taxes, schools, and buyer pools. A beautiful renovation in Baltimore City might be worth $400,000. The identical house across the county line in Baltimore County could be worth $550,000.

Over-improving for the neighborhood. Installing a $75,000 kitchen in a neighborhood where the best comps top out at $250,000 is burning money. The market won’t pay for improvements beyond the area’s ceiling. Know your neighborhood’s maximum values before planning renovations.

Ignoring Baltimore’s historic districts. Properties in CHAP (Commission for Historical and Architectural Preservation) districts require special permits for exterior work. This adds months to timelines and thousands to budgets. Factor this into your ARV and holding costs or avoid these properties entirely.

Missing flood zone impacts. Maryland has extensive flood zones along the Chesapeake Bay and tributaries. Properties in flood zones require expensive insurance and sell for less. Always check flood maps before calculating ARV. A property in a flood zone might be worth 10-20% less than an identical property outside it.

Using old or off-market comps. In a shifting market, a comp from nine months ago is ancient history. Stick to sales within 90-180 days. Also verify your comps were arms-length transactions. That bargain comp might be a family transfer or foreclosure that doesn’t reflect market value.

How Hard Money Lenders Evaluate Your ARV

When your loan application hits my desk, I’m not taking your ARV at face value. Lenders don’t like to see unrealistic ARVs from their borrowers because it’s an indicator the borrower doesn’t fully know their numbers. We review comps on the MLS and sometimes have a third-party BPO or agent provide a CMA (comparable market analysis). Here’s exactly what I’m looking for:

First, I check if your comps are actually comparable. If you’re claiming a $400,000 ARV but every comp requires massive adjustments to get there, that’s a red flag. The best ARVs are supported by nearly identical recent sales requiring minimal adjustments.

Second, I evaluate your renovation plan against your claimed ARV. If you’re planning builder-grade finishes but using luxury comps, the numbers don’t work. Your finishes need to match or slightly exceed your comps to achieve your projected value.

Third, I assess market velocity. Even a perfect ARV means nothing if properties sit for 200+ days. In slow-moving Baltimore neighborhoods, I’ll discount ARV by 5-10% to account for carrying costs and price reductions.

The investors who get quick approvals provide detailed comp analysis with minimal adjustments, realistic renovation budgets with contractor bids, and conservative ARV projections leaving room for error. They make my job easy by doing theirs thoroughly.

Want to improve your approval odds? Include 6-8 comps, not just three. Show me closed sales AND active listings. Provide photos of your comps and detailed adjustment explanations. The more evidence supporting your ARV, the faster I can say yes.

Essential Tools for Maryland Real Estate Investors

Accurate ARV calculation requires the right data sources. Here’s what I recommend:

Bright MLS: The gold standard for Maryland real estate data. Partner with an investor-friendly agent to help pull accurate comps for you. MLS provides sold prices, days on market, seller concessions, and detailed photos you won’t find elsewhere.

PropStream: Excellent for investors without MLS access. Aggregates public records and MLS data with powerful filtering tools. Costs around $100/month but pays for itself with one good deal.

Maryland SDAT: Free public records for verifying ownership and sale history. Every Maryland investor should bookmark this site for due diligence.

Local permit databases, including those for Baltimore City and PG County, as well as many other Maryland counties, offer online permit searches. Check permit history before calculating ARV. Unpermitted work can torpedo your resale value.

Maryland Land Rec: Free public record search for recorded instruments, including Deeds, Deeds of Trust, Assignments of rents/leases, etc.

FEMA flood maps: Critical for waterfront and low-lying properties. Properties in flood zones face insurance costs that affect buyer demand and final ARV.
