How much do condo fees reduce what you can borrow in Arlington?

Your lender counts the full condo fee as part of your monthly housing payment, exactly like principal, interest, and taxes. At the 6.95% average 30-year fixed rate Freddie Mac reported on September 17, 2026, every $100 of monthly fee eats roughly $15,100 of loan capacity. A $700 fee and a $400 fee on two identically priced Arlington units are a $45,000 difference in what you can borrow — before you’ve compared a single floor plan.

Most buyers treat the condo fee as a utility bill. Something you notice, grumble about, and move past.

Your lender treats it as debt.

That difference is why two buyers with the same income, the same down payment, and the same credit score can walk out of the same lender’s office approved for wildly different numbers — because one of them fell in love with a Rosslyn high-rise carrying an $850 fee and the other is looking at garden-style units in Virginia Square at $310.

I’ve watched this blow up deals at the eleventh hour more times than I can count. The unit appraises. The buyer is solid. And the fee pushes the ratio one point over the line.

What Every $100 of Condo Fee Actually Costs You

Fannie Mae’s Selling Guide spells this out. Monthly housing expense — the number underwriters measure against your income — is defined as principal and interest, property insurance, real estate taxes, ground rent, special assessments, and any owners’ association dues (Selling Guide B3-6-03). The fee isn’t a side expense. It’s inside the ratio.

So the question becomes: how much loan does a dollar of fee displace?

At 6.95%, a 30-year fixed loan costs about $6.62 per month for every $1,000 borrowed. Run that backward and you get the number that matters:

• $300 monthly fee — consumes roughly $45,300 of loan capacity
• $500 monthly fee — roughly $75,500
• $700 monthly fee — roughly $105,700
• $900 monthly fee — roughly $136,000

Put differently: a buyer looking at a high-fee Pentagon City tower and a buyer looking at a modest Shirlington building can have the same paycheck and be shopping $90,000 apart.

Here’s what that looks like on two Arlington listings at the same price. Two units, both $550,000, both 20% down.

• Loan: $440,000 → principal and interest of about $2,913
• Arlington County real estate taxes: at the adopted CY 2026 rate of $1.053 per $100 of assessed value, roughly $483 a month on a $550,000 assessment
• HO-6 unit policy: call it $40

Unit A carries a $425 fee. Total monthly housing payment: $3,861.

Unit B carries an $815 fee. Total monthly housing payment: $4,251.

Same price. Same loan. A $390 monthly gap — $4,680 a year — that shows up nowhere in the list price and everywhere in your approval letter.

Fannie Mae caps debt-to-income at 50% for loans run through Desktop Underwriter (Selling Guide B3-6-02), and most lenders get conservative well before that. If you’re carrying a car payment and a student loan, Unit B can be the one that doesn’t clear — on a unit you could afford in every sense except the one the computer checks.

This is a conversation worth having with your lender before you start touring, not after you’ve written an offer. Ask for your maximum purchase price at three different fee levels — $400, $600, $800. You’ll learn more about what you can actually shop for in ten minutes than in three weekends of open houses.

Why the Cheapest Fee in the Building Is Often the Warning Sign

Now the part that trips up experienced buyers.

A low fee looks like a win. Sometimes it is — a well-run, newer building with few amenities and no debt genuinely costs less to operate. Plenty of those exist in Arlington.

But a low fee can also mean the board is underfunding the building’s future, and that’s a problem you inherit at settlement.

Fannie Mae requires the association’s budget to allocate at least 10% to replacement reserves for capital expenditures and deferred maintenance before a unit in that project is eligible under a Full Review (Selling Guide B4-2.2-01, updated August 5, 2026). The calculation is simple enough that you can run it yourself: divide the annual reserve allocation by the annual assessment income.

A building collecting $2.4 million in fees and putting $150,000 into reserves is at 6.25%. Under the bar.

When a project misses that threshold — or carries too much delinquency, since Fannie also limits a project to no more than 15% of units 60 or more days past due on common expense assessments — it can lose warrantability. And a non-warrantable Arlington condo is a different purchase entirely: portfolio lenders, higher rates, larger down payments, and a much smaller pool of buyers when you go to sell.

The other trapdoor is the special assessment. Underfunded reserves don’t make the roof, the elevators, or the facade repairs go away. They just defer them into a lump-sum bill later. And per that same Fannie Mae definition above, special assessments count in your housing expense too — so the “savings” from a low fee can come back as a payment that hurts your ratio worse than the higher fee would have.

I tell every buyer the same thing: a $425 fee in a building with a funded reserve account is cheaper than a $425 fee in a building that’s been coasting. You’re just paying at different times.

If you want the full walkthrough of how to evaluate this, I’ve written a longer piece on reading a condo reserve study before you buy and another on what a pending special assessment means for your purchase.

What to Actually Check Before You Commit

Virginia is a caveat emptor state. The seller’s disclosure is largely a formality, and the burden of finding this out sits with you. The good news is that the resale package gives you almost everything you need — if you know which pages matter.

Work through this list:

1. Run the reserve percentage yourself. Annual reserve contribution ÷ annual assessment income. If it’s under 10%, ask why, and ask what the reserve study says.
2. Check the reserve study’s date. Lenders can only use a study completed within three years. An eight-year-old study tells you the board hasn’t looked closely in a while.
3. Look at the delinquency report. More than 15% of units running 60+ days behind is a financing problem, not just a bookkeeping one.
4. Pull five years of budgets, not one. A fee that climbed 4% a year is a board keeping pace. A fee that jumped 22% in one year is a board catching up — and probably not done.
5. Find out what the fee includes. Some Arlington high-rises bundle water, sewer, gas, and sometimes basic cable. Many garden-style buildings in Ballston and Virginia Square include almost nothing. Two buildings with a $150 fee gap can have identical true costs.
6. Read the last two years of board meeting minutes. This is where the elevator modernization, the facade study, and the insurance renewal shock show up months before they hit a budget.

Number five matters more than buyers expect. When you’re comparing a Courthouse building at $520 against a Clarendon building at $390, and the first one covers your utilities, the gap is much narrower than the listings suggest — and your lender is counting the full $520 either way.

Every building in Arlington is different, and the only way to know what a specific fee is buying you is to look at that building’s actual books against what comparable units in it have sold for. That’s the work I do with buyers before they write an offer — not after.

The condo fee isn’t a footnote on the listing. It’s the single line item most likely to change what you can buy, and the one most likely to be hiding something about the building’s finances.

Before you narrow your search, get your real purchase price at multiple fee levels — and get a read on the reserves in any building you’re serious about.

Frequently Asked Questions

Do condo fees count toward your debt-to-income ratio?

Yes. Fannie Mae’s Selling Guide includes owners’ association dues and special assessments in monthly housing expense, which is the number measured against your income. The full fee counts — you don’t get to exclude any portion of it, even if it covers utilities you’d otherwise pay separately.

How much does a $500 condo fee reduce what I can borrow?

At the 6.95% 30-year fixed rate Freddie Mac reported for September 17, 2026, roughly $75,500 of loan capacity. The exact figure moves with rates, so re-run it with your lender using the rate you’re actually quoted.

Is a low condo fee always better in Arlington?

Not necessarily. A low fee can reflect an efficient, well-reserved building, or it can reflect a board that isn’t funding future repairs. Fannie Mae wants to see at least 10% of the budget going to replacement reserves — check that number before you treat a low fee as a bargain.

Can a high condo fee make a building non-warrantable?

The fee amount itself doesn’t. What affects warrantability is the building’s financial condition — reserve funding, delinquency rates, litigation, and commercial space ratios. A high fee that’s actually funding reserves usually helps a building’s standing with lenders rather than hurting it.

Do condo fees affect my closing costs?

Indirectly. You’ll typically prepay a month or two of fees at settlement, and many Arlington associations charge a resale package fee and a capital contribution or move-in fee at closing. Those are separate from the fee itself — I break the full list down in my guide to closing costs for Arlington condo buyers.
