Improvement exchanges show up more in Michigan than a lot of investors expect, usually because the replacement property they want is close but not quite right, and the missing piece is a buildout that has to happen fast enough to count inside the exchange window. The structure has real advantages when it fits, but it adds a construction timeline on top of an already tight federal clock.
Why Construction and a 180-Day Clock Rarely Get Along
An improvement exchange lets construction, tenant improvements, or other value-add work on the replacement property count toward the exchange, and it is worth understanding clearly before committing to a construction-heavy replacement, but only the work actually completed and paid for before the 180-day deadline counts. That is a tight window for meaningful construction almost anywhere, and Michigan's winter construction season narrows it further. A framework we see often is an auto-supplier expanding into a raw industrial shell in Sterling Heights or Auburn Hills, where permitting and contractor mobilization alone can eat a third of the available time before a shovel goes into frozen ground.
A relinquished property sale that closes in October puts nearly the entire construction window across a Michigan winter, which changes the whole planning conversation. We push those investors to have contractor bids, permit applications, and a realistic weather-adjusted schedule ready before the relinquished sale even closes, since starting that process after day one leaves too little runway.
What Actually Gets Built This Way
The improvement work we help coordinate tends to fall into a few repeatable categories across the state, each with its own permitting and inspection rhythm.
- converting vacant industrial shells near Detroit-metro supplier corridors into usable manufacturing space
- retail buildouts in growing West Michigan submarkets
- medical office tenant improvements near Grand Rapids' Medical Mile or the Ann Arbor hospital corridor
- multifamily unit upgrades in Lansing and mid-Michigan markets
The Exchange Accommodation Titleholder Question
Most improvement exchanges require an exchange accommodation titleholder to hold the replacement property while construction happens, since the investor cannot hold title and have the QI simultaneously fund ongoing improvements the way the structure requires. Setting this up correctly, with the right entity and the right funding mechanism, has to happen before any construction contract is signed, not after ground is broken. We treat the titleholder entity formation and funding agreement as the very first task on any improvement exchange, ahead of even finalizing the construction scope, because every downstream draw depends on that structure being correctly in place.
Separating What Counts From What the Investor Wants
Not every improvement an investor eventually wants counts toward the exchange. Only work completed and documented with invoices and draw records before day 180 qualifies. We separate that must-finish scope from any additional post-closing work the investor plans, so the construction budget and schedule track what the exchange actually requires rather than the full renovation wish list. A Grand Rapids medical office buildout, for example, might have a core tenant improvement scope that has to finish before day 180 and a separate cosmetic upgrade the investor can complete on their own timeline afterward without affecting the exchange value.
Tracking Draws Against the Deadline
Every improvement exchange file carries a draw schedule tied directly to the 180-day date, reviewed against actual contractor progress rather than the original bid timeline. When a Michigan winter pushes a contractor's start date back two or three weeks, that draw schedule is where the slippage becomes visible early enough to act on it. We review it against actual site photos and paid invoices rather than relying only on contractor status updates, since a schedule built on optimistic verbal progress reports tends to look fine right up until it does not.
Common 1031 Exchange Questions
Does all construction on a replacement property count toward an improvement exchange?
No, only work completed and paid for, with proper documentation, before the 180-day deadline counts. Work finished after that date does not add to the exchange value.
Why is an exchange accommodation titleholder needed?
The structure generally requires a separate titleholder to hold the replacement property during construction while the qualified intermediary manages funding, since the investor cannot do both roles at once under the exchange rules.
Does Michigan's winter construction season affect improvement exchange planning?
Yes, permitting delays and contractor mobilization in cold months can eat meaningfully into the 180-day window, so we build the construction schedule with that seasonality in mind from the start.
What happens if construction is not finished by day 180?
Only the completed, documented portion of the improvement counts toward the exchange value. Unfinished work does not retroactively qualify, which is why the draw schedule is tracked so closely against the deadline.
When should construction planning start on a Michigan improvement exchange?
Before the relinquished property even closes, ideally with contractor bids and permit applications already underway, since a winter-heavy construction window leaves very little room to start the process from zero on day one.
Can I use my own contractor on an improvement exchange?
Generally yes, subject to the structure's requirements around the exchange accommodation titleholder and documented draws, though we confirm the specific arrangement works with the funding mechanism before any contract is signed.
Does the improvement exchange structure cost more to set up than a standard exchange?
Yes, the exchange accommodation titleholder arrangement adds legal and administrative cost beyond a standard forward exchange, which is why we only recommend this structure when the construction need is real and cannot be solved another way.
