Thinking about selling your Chicago two-flat and trading up to a Lake Michigan rental without triggering a big tax bill? You are not alone. With a properly structured 1031 exchange, you can defer capital gains while pivoting into a property that fits your next chapter. This guide walks you through the rules, the timeline, Chicago-specific costs, and smart steps to make your move. Let’s dive in.
How a 1031 exchange works
A 1031 exchange lets you defer capital gains taxes by swapping real property held for investment or business use for other like-kind U.S. real property. Personal residences do not qualify. The IRS requires you to report the transaction on Form 8824, and strict identification and closing deadlines apply. You can review the core rules in the IRS Instructions for Form 8824 and Publication 544 for more detail on timing and mechanics. Learn more about like-kind exchanges and reporting and review timing rules in Publication 544.
The 45/180-day clock
You must identify your replacement property within 45 days after transferring your two-flat and complete the purchase within 180 days. These deadlines are firm and counted from the transfer date. Missing either deadline usually disqualifies the exchange. See the IRS timing rules in Publication 544.
Use a Qualified Intermediary
In a delayed exchange, you cannot receive the sale proceeds. A Qualified Intermediary holds your funds and facilitates the purchase. Choose a reputable, independent QI, since certain people are considered disqualified. Read a consumer overview of QIs and disqualified persons.
Watch for boot and debt
If you receive cash or reduce your mortgage debt in the swap, that “boot” can trigger taxable gain. For full deferral, reinvest all net proceeds and replace equal or greater debt on the new property. The IRS details boot and exchange math in Form 8824 instructions.
Special rules for Chicago two-flats
If you lived in one unit and rented the other, only the investment portion is eligible for 1031 treatment. Document leases, rental ads, Schedule E reporting, and management activity to substantiate investment use. See common mixed-use questions and best practices.
Related-party deals and entity shifts can create added risk, including forced gain recognition if a related party sells within two years. Make sure the entity structure and counterparties fit IRS rules. Review related-party reporting in the Form 8824 instructions.
Finally, even though a 1031 defers gain, depreciation recapture can apply when the taxes eventually come due. It is important to understand how unrecaptured Section 1250 gain may be taxed later. See IRS guidance on depreciation recapture.
From two-flat to a Lake Michigan rental
Choose the right lakefront submarket
Lakefront and near-lake neighborhoods vary widely. Premium areas like Lincoln Park, Lakeview, and Near North often post strong rent growth yet come with higher entry prices and tighter yields. Nearby lakefront suburbs, including Evanston, can offer different rent and cap rate dynamics. See Berkadia’s Chicago multifamily trends.
Long-term vs short-term renting
If you are eyeing short-term rentals in Chicago, know that the city enforces strict registration, primary-residence limits for many buildings, and a prohibited buildings list. Condo or HOA rules may also restrict rentals. Always check both municipal code and building bylaws before you buy. Review Chicago’s shared housing and vacation rental code.
Diligence for rentals near the lake
Plan for a thorough property and code review. Verify building condition, open violations, local rental registration needs, condo or HOA rental limits, and parking or amenity rules that support tenant demand. In city neighborhoods, make sure your intended use aligns with zoning and licensing requirements.
Closing costs and taxes to plan for
Chicago’s real property transfer taxes meaningfully affect your net. The city portion is $3.75 per $500 of price, typically paid by the buyer, and the CTA portion is $1.50 per $500, typically paid by the seller. These are separate from Illinois state and county transfer taxes. See how Chicago’s municipal and CTA transfer taxes are applied.
Illinois also levies state and county transfer taxes that commonly total $0.75 per $500 combined, although customs on who pays can vary by contract. Confirm the exact split during negotiations and budget early. Review Illinois transfer stamp guidance.
If you plan to move in later
Many owners aim to convert the replacement property to personal use down the road. The IRS created a safe harbor for dwelling units that meet objective rental and personal-use standards over a 24-month period. Following this safe harbor reduces audit risk by showing the property was held for investment at exchange time. Read IRS Rev. Proc. 2008-16.
Your step-by-step roadmap
- Pre-list planning
- Confirm your two-flat’s investment use, especially if it was mixed use. Gather leases, rent rolls, and Schedule E.
- Talk with a 1031-experienced CPA or tax attorney about structure, debt, and timing.
- Line up a Qualified Intermediary
- Engage a bonded, independent QI before you close the sale. Understand how QIs work.
- Know your start date
- Your 45-day and 180-day clocks start when you transfer the two-flat. Review the IRS timing rules.
- Identify within 45 days
- Name your target properties in writing. Consider more than one lakefront or near-lake option to stay flexible.
- Close within 180 days
- Coordinate lender, title, and QI early. Reverse or improvement exchanges exist if needed, but they are more complex and costly.
- Diligence your lake property
- Verify rental rules, HOA limits, and code compliance. Confirm realistic rents and expenses for underwriting. Check Chicago’s STR rules if relevant.
- Budget closing costs
- Add Chicago city and CTA transfer taxes plus state and county stamps. See Chicago’s transfer tax framework and Illinois stamp guidance.
- Report properly
- File Form 8824 for the exchange year and retain all QI statements, identification notices, and closing statements. Review exchange reporting.
Common pitfalls to avoid
- Missing the 45-day or 180-day deadlines.
- Hiring an inexperienced or undercapitalized QI.
- Reducing debt on the replacement property and creating taxable boot.
- Failing to isolate the investment portion of a mixed-use two-flat.
- Buying a condo without checking HOA and Chicago short-term rental restrictions.
- Overlooking Chicago and Illinois transfer tax costs.

Can I 1031 into a Lake Michigan condo and use it for short-term rentals?
- Possibly, but Chicago’s short-term rental rules and many condo bylaws restrict or prohibit STRs, so verify both before you buy.
What closing taxes should I expect when selling or buying in Chicago?
- Budget for the city transfer tax and CTA portion, plus Illinois state and county transfer stamps, which together materially affect closing costs.
