The information below is general educational content, not tax or legal advice. A 1031 exchange has strict rules and unforgiving deadlines. Always work with a qualified intermediary, a CPA, and, where a trust or entity is involved, an estate or business attorney before you act. David Mount is a licensed REALTOR®, not a tax advisor, attorney, or qualified intermediary.

Why Northern Virginia Works for Buy-and-Hold Investors

Northern Virginia is one of the steadiest rental markets in the country, and there are real reasons for that. The federal government, the defense and intelligence sector, the Loudoun County data-center corridor, and a wide range of private employers keep tenant demand high and reliable, so it doesn’t rise and fall with any one industry. For a buy-and-hold investor, that usually shows up as low vacancy, rent that gets paid, and solid long-run appreciation on well-located single-family and townhouse properties.

David Mount has spent 12-plus years and 200-plus transactions in this market. He owns Virginia rental property himself, and he represents investors on both sides: selling rentals that have appreciated and buying the next ones, often through a 1031 exchange. He looks at your portfolio the way you do, as a long-term hold rather than a one-time commission.

“I own rentals in this market myself, so I’m not guessing about what makes a good one in Fairfax County or Loudoun. I underwrite your deal the same way I underwrite mine. I’m looking at rent versus price, the tenant pool, what it sells for when you exit, and what the property does for your basis and your taxes over ten years, not just at the closing table.”
David Mount, REALTOR®

What Is a 1031 Exchange? (Plain English)

A 1031 exchange, named for Section 1031 of the Internal Revenue Code, lets you sell real property you hold for investment or business use and roll all of the proceeds into another “like-kind” investment property without paying the capital-gains tax or depreciation recapture you would otherwise owe at sale. The tax isn’t forgiven. It’s deferred, and it can stay deferred for as long as you keep exchanging.

“Like-kind” is much broader than most investors expect. Since the 2017 tax law, only real property qualifies, but any U.S. real estate held for investment counts as like-kind to any other. You can exchange a Fairfax County townhouse rental for a single-family rental in Loudoun, swap raw land for an apartment building, or trade several small rentals for one larger one. What doesn’t qualify is your primary residence, a vacation home you use personally, or a property you bought mainly to flip.

The 1031 Timeline: the 45-Day and 180-Day Rules

The calendar is the part that trips up even experienced investors, because the clock is strict and the IRS will not extend it if you miss a deadline. Two deadlines start the day your old property closes.

The 45-Day Identification Period

From the day your sale closes, you have 45 calendar days to identify your replacement property in writing, signed and delivered to your qualified intermediary. Weekends and holidays count against you. This is why David lines up replacement candidates before your sale closes. Forty-five days goes quickly when inventory is tight.

The 180-Day Exchange Period

You then have 180 calendar days from the sale closing to actually close on the replacement property, or until the due date of your tax return for that year (including extensions), whichever comes first. A sale that closes late in the year can quietly shorten your 180 days, so talk to your CPA about filing an extension.

“The most expensive 1031 mistake I see is treating the 45-day clock like it starts when you find a property. It starts the day your sale closes. By the time a lot of investors call an agent, a week or two is already gone. We start looking at replacement properties before your old one is even under contract. That’s how you protect the deferral.”
David Mount, REALTOR®

The Three Identification Rules

When you identify replacement property inside those 45 days, the IRS gives you three ways to do it. You only have to meet one of them.

• Three-Property Rule. Identify up to three properties of any value, and you can close on any or all of them. This is the rule most investors use.
• 200% Rule. Identify as many properties as you want, as long as their combined fair-market value stays under 200% of what you sold. This helps when you’re trading one property for several.
• 95% Rule. If you go past both limits above, you have to actually acquire at least 95% of the total value you identified. It’s the escape hatch, and it’s rarely used on purpose.

What It Takes to Defer 100% of the Tax

To defer all of your gain, the replacement property generally needs to be equal or greater in value, equity, and debt, and you have to reinvest all of the net proceeds. Anything you pull out, whether it’s cash or a drop in your mortgage debt that you don’t replace, is called “boot,” and boot gets taxed.

The simple version: trade up or trade even, and reinvest everything. If you want to take some cash off the table, you still can. You’ll just pay tax on that piece while deferring the rest. David models this with your CPA before you list, so you know exactly what full deferral takes for your specific numbers.

Exchanging Property Held in a Trust or LLC

A lot of serious investors hold rentals in a revocable living trust or a single-member LLC, for privacy, estate planning, or liability reasons. For 1031 purposes, that’s usually good news, because of the same-taxpayer rule. The taxpayer who sells the old property has to be the same taxpayer who buys the new one. A revocable living trust and a single-member LLC are generally treated as “disregarded entities” for federal income tax, which means the IRS looks straight through them to you, the grantor or sole member. So a property held in your living trust normally buys and sells as the same taxpayer, and the exchange holds together.

It gets more technical with partnerships, multi-member LLCs, and irrevocable trusts, where the “taxpayer” may be the entity itself rather than you personally, and where “drop and swap” structures sometimes come up. Those are the situations to map out with your CPA and attorney before you list, because how title is held when you sell has to match how it’s held when you buy.

“If your rentals are in a living trust, that usually makes a 1031 easier, not harder. The trust and you are the same taxpayer as far as the IRS is concerned. But the second we’re dealing with a partnership, a multi-member LLC, or an irrevocable trust, I want your attorney and CPA in the room before we list. Title at the front of the exchange has to match title at the back.”
David Mount, REALTOR®

Reverse and Improvement Exchanges

The standard 1031 is a “delayed” or “forward” exchange, where you sell first and then buy. But inventory in Northern Virginia is tight, and sometimes you find the right replacement before your current property sells. Two less-common structures handle that.

• Reverse exchange. An exchange-accommodation titleholder buys and “parks” your replacement property first, and you then sell your old one inside the 180-day window. It costs more and takes more coordination, but it lets you lock down a property you can’t afford to lose.
• Improvement (construction) exchange. Your exchange funds pay for improvements to the replacement property before you take title, so you can put equity into renovations or new construction and still defer.

David has coordinated investor exchanges through qualified-intermediary partners who handle both structures. When a reverse or improvement exchange is the right tool, he brings in the right specialist instead of forcing a standard exchange that doesn’t fit.

“Swap Till You Drop”: 1031 and the Stepped-Up Basis

This is why 1031 exchanges are a cornerstone of family wealth, and why they matter so much for an investor who holds in a trust for estate-planning reasons. Every exchange defers your gain. If you keep exchanging and never cash out, that deferred gain just rides along with you. When you pass away, your heirs generally receive the property at a stepped-up basis equal to its fair-market value at your death (IRC §1014), and the deferred capital-gains tax can disappear entirely.

Investors call this “swap till you drop.” Paired with a well-built trust, it’s one of the most powerful and fully legal tools in real estate for handing an appreciated portfolio to the next generation with very little tax drag. It’s also the kind of long-horizon plan that rewards working with one agent who knows your whole portfolio, not a different agent on every deal.

Single-Family and Townhouse Rentals, and Why Not Condos

David steers investor clients toward single-family homes and townhouses rather than condos, and that’s a deliberate call based on experience. Single-family and townhouse rentals in Northern Virginia tend to hold longer-tenure tenants, appreciate more reliably, and sidestep the two things that quietly eat into condo returns: special assessments and condo-association rental caps. Plenty of NoVA condo associations limit how many units can be rented, which can leave an investor unable to lease the unit, or unable to sell it to another investor, at exactly the wrong moment. Monthly condo fees also come straight out of your cash flow, and you don’t control them.

That doesn’t mean condos never work. But if you’re a buy-and-hold investor who wants steady cash flow, appreciation, and a clean exit, single-family homes and townhouses are the stronger base, and they’re where David concentrates his market knowledge and his own holdings.

Where David Invests and Sells: Fairfax County and Loudoun

David’s deepest investor track record is in Fairfax County and Loudoun County, specifically Ashburn and Leesburg. Those are markets where he has personally sold investment-grade single-family and townhouse properties, and where he can talk about rent-to-price ratios, tenant demand, and resale liquidity from real deals instead of generic numbers.

Fairfax County has the widest mix of investor-friendly single-family and townhouse inventory in Northern Virginia, supported by employers, schools, and transit. Submarkets like Burke, Springfield, Centreville, and Fairfax pair solid rents with deep buyer demand when it’s time to sell. Loudoun County, and Ashburn and Leesburg in particular, has been one of the region’s best appreciation stories thanks to the data-center corridor and steady in-migration, so it tends to suit investors who weight long-run appreciation alongside cash flow.

“Fairfax County and Loudoun are where I put my own money and where I’ve sold investment property for clients. I’ll give you a straight read on which submarket fits your strategy, cash flow now or appreciation over ten years, because I’m holding in these same neighborhoods.”
David Mount, REALTOR®

Why Experienced Investors Keep One Agent for the Long Haul

If you’ve built a portfolio worth several million dollars, you’ve almost certainly worked with more than one agent, and you know the difference between someone who closes a transaction and someone who understands your whole strategy. The investors David fits best aren’t looking for another order-taker. They want one REALTOR® they trust, someone who knows their portfolio, their entities, their CPA, and their goals well enough to bring them the right deal before it hits the market and to flag the right time to exchange.

That’s the relationship David is built for. He invests himself, he holds for the long term, and his business runs on repeat clients and referrals rather than one-and-done closings. The clearest proof of that is a client who picked David for five straight deals after three decades of working with other agents.

A Real Investor Relationship: The Tom Strother Story

Tom Strother is the clearest example of how David works with investors. By Tom’s own count, he has worked with at least 15 different real estate agents over 30 years of buying and selling homes, some for investment and some for his family, and he chose David for five straight transactions and called him “as good as they get.” That’s not a one-time closing. It’s an investor deciding, after decades of experience with other agents, that he wanted David on his team for deal after deal. If you’re trying to decide whether David is worth a long-term relationship, Tom already answered the question.

Frequently Asked Questions About 1031 Exchanges and Investment Property in Northern Virginia

What is a 1031 exchange in simple terms?

A 1031 exchange lets you sell investment real estate and reinvest the proceeds into another investment property while deferring the federal capital-gains tax and depreciation recapture you would normally owe at sale. The tax is postponed, not erased. You have to use a qualified intermediary and follow strict 45-day and 180-day deadlines.

How long do I have to complete a 1031 exchange?

Two clocks start the day your old property closes. You have 45 calendar days to identify replacement property in writing, and 180 calendar days to close on it, or your tax-return due date for that year, whichever comes first. The IRS does not grant extensions for missed 1031 deadlines, so timing matters a lot.

Can I do a 1031 exchange on a rental property held in a trust?

Usually yes, and it’s often easier. A revocable living trust is typically a disregarded entity for federal tax, so the IRS treats the trust and you as the same taxpayer, which satisfies the same-taxpayer rule. Irrevocable trusts, partnerships, and multi-member LLCs are more complicated, so bring your CPA and attorney in before listing.

Do I need a qualified intermediary, or can I hold the money myself?

You have to use a qualified intermediary. If you take actual or constructive receipt of the sale proceeds, even for a moment, the IRS treats it as a taxable sale and the exchange fails. The qualified intermediary holds the funds between the sale and the purchase. David can introduce you to experienced Northern Virginia qualified intermediaries.

What kinds of property are “like-kind” for a 1031 exchange?

Since 2017, only real property qualifies, but the definition is broad. Any U.S. real estate held for investment or business is like-kind to any other. You can exchange a townhouse rental for a single-family rental, land for an apartment building, or several rentals for one. Your primary residence, a personal vacation home, and flip properties do not qualify.

Can I exchange one property for several, or several for one?

Yes. The identification rules, meaning the three-property rule, the 200% rule, and the 95% rule, are built to let you roll several rentals into one larger property or split one appreciated property into several. David and your qualified intermediary structure the identification so it fits your strategy and stays inside the rules.

What is “boot” and how do I avoid being taxed on it?

Boot is any value you receive that you don’t reinvest, like cash you pocket or a reduction in your debt that you don’t replace. Boot gets taxed. To defer all of your gain, buy a replacement of equal or greater value, reinvest all of your equity, and replace your debt or add cash. David models this with your CPA before you list.

Why does David focus investors on single-family homes and townhouses instead of condos?

Single-family and townhouse rentals in Northern Virginia tend to appreciate more reliably, hold longer-tenure tenants, and avoid two condo-specific risks: rising special assessments and association rental caps that can limit your ability to lease or sell to another investor. For steady buy-and-hold returns, they’re the stronger base.

Which Northern Virginia areas are best for buy-and-hold investment?

It depends on whether you weight cash flow or appreciation. Fairfax County has the widest investor-friendly single-family and townhouse inventory with deep exit demand. Loudoun County, including Ashburn and Leesburg, has been a top appreciation market driven by the data-center corridor. David invests and sells in both and will give you a straight read on which one fits your strategy.

What happens to the deferred tax if I never sell?

If you keep exchanging and hold until death, your heirs generally receive the property at a stepped-up basis equal to its fair-market value at that time (IRC §1014), and the deferred capital-gains tax can be wiped out. Investors call this “swap till you drop,” pairing 1031 exchanges with trust-based estate planning to pass a portfolio along with very little tax.

Do I have to find the replacement property before I sell?

Not legally, but in practice you should be looking before you list. You only get 45 days to identify after closing, and Northern Virginia inventory is tight, so David lines up replacement candidates while your old property is being prepped and marketed. That way the 45-day clock protects the deferral instead of threatening it.

Does Virginia tax a 1031 exchange differently than the IRS?

Virginia generally follows the federal treatment of 1031 exchanges, so a properly structured exchange typically defers Virginia tax along with federal tax. State conformity can change, so confirm your specific situation with a Virginia CPA. David coordinates with your tax professional the whole way through.

How David Mount Helps Investors in Northern Virginia

David Mount has spent 12-plus years and 200-plus transactions building a Northern Virginia real estate practice, owns rental property in Virginia himself, and represents buy-and-hold investors on both the buy and sell sides. Here’s what that looks like in practice.

He’s fluent in the 1031 mechanics, the 45 and 180-day deadlines, the identification rules, boot, and same-taxpayer issues, and he coordinates with your qualified intermediary, CPA, and estate attorney so nothing falls through the cracks. He won’t act as your tax advisor. He’s the real estate quarterback who keeps the deal and the deadlines moving together.

Because he works with investors over the long term and runs a referral-based business, he often hears about investment-grade single-family and townhouse properties before they hit the open market, and he knows how to put your listing in front of the right investor buyers when you sell. He evaluates rentals the way he evaluates his own, looking at rent versus price, the tenant pool, capital-expense exposure, and what it sells for on exit, not just the list price.

Most of all, he’s built for a real partnership. The Tom Strother relationship, five transactions with a client who had worked with at least 15 agents over 30 years, is the model. David is the right fit for investors who want one REALTOR® they trust across many transactions and many years.
