Delaware 1031 Exchanges and DSTs: Property, Taxes, and Coastal Rentals

By Jerry Baker

A Delaware 1031 exchange can defer gain when qualifying investment or business real estate is exchanged for other qualifying real estate. Buying property in Delaware is a different decision from buying an interest in a Delaware statutory trust, or DST. This guide separates those choices and explains the state tax, rental, coastal, and property checks that can affect your next investment.

First, separate the location from the ownership structure

When someone asks me about a “Delaware investment,” I want to know what they mean. Are we discussing a building in Wilmington, a rental near the beach, or a DST that owns buildings in other states? Those are different research assignments. The word Delaware alone does not tell us where income comes from or which property rules apply.

For federal tax purposes, Section 1031 generally covers real estate held for investment or productive use in a business. It does not turn a personal vacation home into exchange property just because the next purchase will earn rent. A qualifying exchange defers gain rather than giving the owner a fresh start with no future tax issue. [1]

A deferred exchange generally has a 45-day written identification period. The purchase must be completed within 180 days or the federal tax return's due date, including extensions, if earlier. The identification rules also limit the properties you can list. Put the qualified intermediary in place before the sale closes and have counsel check control of the proceeds. [2]

IRS Revenue Ruling 2004-86 addresses a particular DST structure whose interests can be treated as interests in real property for exchange purposes. The ruling restricts what the trustee can do. It does not approve every trust, every offering, or every investor's exchange. Read the actual trust and offering documents with your advisers. [3]

I would keep a simple map in the review file. List the property addresses, each property's role in producing income, and who makes the important decisions. That map is more useful than assuming the trust's legal name describes its real estate.

Delaware still has an income-tax calculation

The Division of Revenue describes a graduated personal income tax. Its top rate is 6.6% at the upper bracket around $60,000 of taxable income. That is a marginal rate, not a statement that all sale proceeds are taxed at 6.6%. Filing status, deductions, income, and residency still need review. [4]

Delaware’s resident tax starts with federal adjusted gross income. State changes and deductions come next. Do not assume every federal deduction carries over unchanged. Section 1106 has specific state changes to depreciation. They apply to covered property placed in service during 2026 through 2030. Ask your CPA to track both sets of basis records for your assets. [5]

For a sale comparison, I would ask the CPA to separate deferred gain, recognized gain, selling costs, depreciation issues, and cash available after closing. Then compare a taxable sale with the proposed exchange using the same price and cost estimates.

It is easy to make an exchange look better by assuming a high tax bill in one case and a generous resale value in the other. Use consistent assumptions. The tax benefit and the investment return deserve separate lines, even when both matter to your decision.

Two closing taxes should not be confused

Delaware's currently posted REW-EST instructions call for estimated income tax on covered nonresident real-estate sales. The stated rates on gain are 6.6% for taxpayers other than C corporations and 8.7% for C corporations. The form includes a way to report a sale or exchange exempt from gain recognition. These are estimated-tax and reporting rules; the form does not make every exchange automatically exempt. [6]

The separate realty transfer-tax instructions show the usual 4% combined rate. That includes 2.5% for the state and 1.5% for the county or municipality. Exemptions and special circumstances must be checked. The instructions expressly include like-kind property in the value calculation. Deferring income-tax gain does not, by itself, eliminate the transfer tax. [7]

Ask the settlement attorney to mark these as separate items on the draft statement. Which return is needed? Who signs it? What evidence supports an exemption? How much money will actually go to the intermediary? Do not use a loan payoff or a rough estimate of profit as a substitute for the required gain calculation.

I would also ask for a second closing statement after all known changes are entered. A last-minute credit, seller repair payment, or changed fee can affect the cash you have to place. The replacement budget should follow the actual closing numbers, with your tax advisers deciding how each item is treated.

An old property-tax bill may be a poor guide

New Castle County's current tax page says fiscal-year 2027 bills, covering July 2026 through June 2027, are due December 31, 2026. It expects bills to be mailed in November and rates to become available on or after October 22. As of this guide's October 6 review, its estimator is not a final bill. Those dates are specific to this cycle and should not be reused for later years. [8]

That timing matters if you are comparing a rental's old expense statement with an offer made today. Request the updated assessment, classification, school district, municipal charges, and any appeal or corrected bill. Ask the county and closing attorney how to handle the period with no final bill yet.

Keep three numbers apart: the property's value, the tax rate, and the amount due. A large change in assessed value does not translate into the same percentage change in tax. Nor does an estimate of a lower rate prove that a particular parcel's expense will fall.

For Kent or Sussex County, obtain that county's actual records and calendar. I would not import New Castle County's payment extension, classifications, or bill estimate into another county's budget. County lines matter even when two properties look similar on a listing site.

Wilmington rentals need more than a rent roll

Wilmington's rental program calls for an annual residential rental license, property registration, and interior and exterior inspections. The city also sets local management duties for owners outside the area. Confirm how those duties apply to the owner and operator, using the license application and current code rather than a general assumption about remote ownership. [9]

I would match the licensed units to the units in the offering. If a seller presents income from three apartments, make sure the legal and inspection file supports those three apartments. Request open violations, completed repair records, and the plan for inspections after the sale.

Then compare the management agreement with the operating budget. Does the fee cover leasing, inspections, emergency calls, and contractor oversight? Which tasks cost extra? Who authorizes a repair when the owner cannot be reached? These questions help show whether buying at a distance fits the amount of work you want to do.

A manager can be valuable without making a property passive in the same sense as a sponsored investment. You may still make decisions, supply more cash, and bear costs outside the management fee. I want those duties visible before we compare the income to another option.

For beach rentals, count the full booking cost

Delaware imposes a 4.5% lodging tax on covered short-term rent. It applies to agreements entered on or after January 1, 2025. The program generally covers stays of no more than 31 consecutive nights, with defined exceptions. Municipal rental taxes are separate. Owners who book directly also have tax and license duties. The rules differ for an owner who uses only a third-party intermediary. [10]

Review a year's booking statements by month. Separate rent, guest taxes, cleaning charges, platform fees, cancellations, owner stays, and money actually paid to the owner. Gross guest payments are not all rental income you can spend. Ask who files each return and handles bookings received outside the main platform.

For a hypothetical comparison, a strong summer can hide a weak annual budget. I would list fixed costs month by month, even when no guest is staying. Insurance, loan payments, management retainers, and repairs do not necessarily wait for the next busy weekend.

If you plan to keep using the property yourself, discuss exchange eligibility before relying on rental income. IRS Revenue Procedure 2008-16 provides a safe harbor for certain dwelling units. It generally requires a 24-month ownership period on the relevant side of the exchange. In each required 12-month period, the unit must be rented at fair rent for at least 14 days. Personal use is capped at the greater of 14 days or 10% of fair-rental days. The full conditions differ for sold and acquired property. Falling outside the safe harbor calls for a facts-based review; it is not an automatic answer either way. [17]

Match the lease file to the cash you receive

For covered Delaware residential tenancies, Section 5514 generally caps deposits at one month's rent for leases of at least a year. It also covers qualifying month-to-month tenancies after a year, with exceptions. Deposit return and damage itemization generally are due within 20 days after the agreement ends. Address rules and other conditions matter. Deposits must stay in a qualifying escrow account. They cannot fund the landlord’s business. [11]

Have local counsel determine which rules apply to the actual lease. A short beach stay and a year-round apartment lease should not share a copied checklist without that review. At closing, reconcile tenant deposits, prepaid rent, pending refunds, and any surety bonds against the records delivered by the seller.

I would not treat prepaid rent for future stays as spare working capital. Put the remaining service obligation next to that money. The buyer may still need to host the guest, clean the unit, pay the platform, or honor a cancellation. A large bank deposit on closing day can be tied to a large amount of work still to come.

Septic records can affect the closing plan

Delaware’s onsite wastewater rule has steps for a sale or transfer. In general, a Class F licensee must pump the system and a Class H licensee must inspect it before closing. There are exceptions. Some recent completion or inspection records and service agreements can meet the rule. Some sale types have a limited extension. Have DNREC and the licensed inspector confirm the path for the property; do not assume a recent pump-out alone satisfies the rule. [12]

Ask for the approved system plan, permit, inspection report, and repair history. Compare the system's approved use with the bedrooms and occupancy in the rental plan. If the seller proposes a repair credit, obtain a written scope and price. Then check whether the work can occur when you need it to occur.

A cash credit does not create room for a replacement system. Nor does it establish an easement, solve a site limit, or guarantee a permit. For a shared system, I would also review who operates it, how owners fund repairs, and what happens if another owner does not pay.

Check the Building Line before pricing an expansion

DNREC requires coastal construction permits for covered work seaward of its Building Line. Work landward of the line in the regulated beach area can require a letter of approval. The review can include exterior work, sand movement, dune crossovers, and other activities, not just a brand-new house. Confirm the required approval for the exact project. [13]

DNREC's coastal guidance also says approval is needed before repairing storm damage. Existing improvements do not prove that the same structure can be rebuilt in the same way. A surveyor can locate the Building Line using the agency's coordinates. The agency advises buyers to check flood zones, easements, and other permit requirements before purchase. [14]

That leads to a practical question: are you buying the property as it operates now, or paying for a future version of it? If the projected return needs a larger deck, more rooms, or a rebuilt structure, I want the approval path in the file. A drawing is a proposal, not a right to build.

Separate the construction review from the insurance review. Ask the insurance professional for the proposed coverage, deductibles, exclusions, and treatment of lost rent. Then decide how much outside cash you could need after a loss. A permit and an insurance policy solve different problems.

Commercial property needs its own environmental check

Delaware's Coastal Zone Act program regulates new or expanded manufacturing in the coastal zone. Its conversion-permit program offers a path to reuse 14 existing heavy-industry sites. Specific limits apply. That program is distinct from residential beach construction approvals. A warehouse or industrial proposal needs review based on its actual location and operations, not merely its property-type label. [15]

For an industrial investment, I would ask what tenants do on the premises, which permits their work needs, and which responsibilities remain with the landlord. Review prior uses as well as current uses. A tenant's lease promise to follow the law does not replace a review of the property's environmental file.

Also ask what happens at lease expiration. How much work would be needed to serve another tenant? Which equipment belongs to the tenant? Is the next business likely to need a new permit review? A long lease can delay those questions, but it does not remove them from the value of the property.

Compare annual cash, not the busiest month's receipts

Here is a hypothetical rental example using $600,000 of investor equity. These are invented teaching figures, not Delaware market averages, an available investment, or projected results.

The result is $2,500 per month on an annual average, or 5% of equity before income tax. It is not a promise of a $2,500 payment each month. The timing of bookings and expenses can produce very different monthly balances.

Now reduce collected rent by $15,000 and add $9,000 of repairs or insurance cost. With other items unchanged, cash falls to $6,000 for the year, or an average of $500 monthly. That is 1% of the equity. A separate reserve would be needed if the timing of bills caused a cash shortage before rents arrived.

For my review, the next step is to replace each assumption with evidence. Use current tax records, written insurance terms, management fees, and actual collected rents. Keep uncertain items in a range. Do not hide an unknown septic cost inside a tidy round repairs allowance.

Put the ownership tradeoffs beside the numbers

A DST may reduce the decisions you make day to day, but it also puts control with the sponsor and trustee. I would compare the debt, lease terms, reserves, fees, and sale plan with the direct property you could buy. Ask which outcome depends on rent growth or an improved resale market.

The SEC warns that private placements may be hard to sell. They can provide less information than public offerings and carry a risk of total loss. Meeting an offering's investor eligibility requirements does not establish that the investment fits your income needs or ability to wait for an exit. [16]

I would finish with three questions. How much cash do you need from this money? How much control and work do you want? What would cause you to need the money back early? The answers may favor direct real estate, a carefully reviewed DST, a mix, or no exchange investment under consideration.

This guide is general education. Your CPA, attorney, qualified intermediary, and property professionals should apply the rules to your situation. It does not claim that any Delaware property or DST is currently available through Baker 1031.

Delaware 1031 exchange and DST FAQs

Does a Delaware statutory trust have to own Delaware property?

The trust name does not tell you where its buildings are. Check the property schedule in the offering. The IRS ruling addresses a qualifying ownership structure, not a guarantee about location or investment quality. [3]

Does a 1031 exchange remove Delaware realty transfer tax?

Not by itself. Delaware's transfer-tax instructions include like-kind consideration in the value calculation. Have the closing attorney check any specific exemption and keep transfer tax separate from income-tax deferral. [7]

Is nonresident estimated tax 6.6% of the gross sale price?

The posted REW-EST instructions describe a gain-based calculation, with 6.6% for taxpayers other than C corporations and a different corporate rate. Exemption reporting and the actual gain calculation need professional review. [6]

Does the state short-term rental tax replace local tax?

No. The Division of Revenue says the state tax is separate from municipal taxes. Confirm who collects and remits each tax for direct bookings and bookings through an intermediary. [10]

Can a recent septic inspection satisfy the transfer requirement?

It may, if the regulation's conditions are met. Recent records, system type, and service arrangements affect the answer. Have the licensed inspector and DNREC confirm rather than relying on an undated seller statement. [12]

Can I assume a damaged beach house can be rebuilt as it was?

No. DNREC says storm-damage repairs need approval, and the Building Line and current requirements may affect the work. Review the allowed reconstruction plan before assigning value to that assumption. [14]

Educational information, not an offer or a personal tax, legal, or investment recommendation. Examples are hypothetical and omit stated adjustments. Tax treatment depends on your facts and current law. Review your transaction with your CPA, attorney, and qualified intermediary. Real estate investments can lose value and may be illiquid.
