Medical Office Replacement Sourcing

A medical office replacement gets built the same way a bid gets built: sale proceeds on one line, debt capacity on the next, and a 45-day identification clock running underneath both. The building gets priced last, after the numbers say what it has to carry.

What Goes on the Estimate Before the Tour

Before a showing gets scheduled, the file needs a tenant-improvement recovery schedule, not a listing sheet. A buildout that cost a health system tenant $60 per square foot to install five years ago still has to amortize against whatever term is left on the lease, and a short remaining term turns that improvement into a liability the next owner inherits rather than an asset they collect on.

Referral-dependent practices carry a different risk line than a hospital-anchored suite. A single-physician imaging tenant with two years left and no health-system affiliation prices differently than a multi-specialty group inside a campus lease structure, and the exchange file should show that difference in writing before an offer goes out.

Corridor Pricing from New Center to the Northern Suburbs

The Detroit Medical Center and New Center corridor trades on hospital proximity and referral density, which supports rent per square foot that suburban medical buildings rarely match on their own. Move north to Southfield, Troy, and Novi and the pricing logic shifts toward parking ratio, ambulatory surgery adjacency, and highway access rather than walk-in referral traffic.

Royal Oak and Grosse Pointe medical space runs smaller floor plates with higher rent per foot, useful for exchangers replacing a larger asset with two or three smaller ones under the three-property identification rule rather than chasing a single large building.

The Diligence Line Items That Actually Move Price

A medical office diligence file should carry the same specificity as a construction takeoff, not a narrative description of the tenant roster.

• Tenant-improvement allowance balance and remaining amortization period
• Referring physician group tenure and health-system affiliation, if any
• Parking ratio per 1,000 square feet against local zoning minimums
• Renewal option pricing already fixed in the lease versus market reset
• CAM reconciliation history for the trailing three years
• Any deferred HVAC or medical-gas system replacement on the capital plan

Basis Variance Block to Block

Detroit medical real estate sits inside a market where value can move sharply from one block to the next, driven by which side of a recovery corridor a building sits on and how recently adjacent parcels changed hands. A medical building two blocks from a redeveloped hospital campus can carry a materially different basis than a comparable building on a block that has not turned over, and that basis gap matters directly for exchange math when the replacement asset has to absorb the full amount of relinquished proceeds to avoid boot.

Comparable sales pulled from a three or four block radius can therefore mislead an appraisal if the radius crosses from a recovered block into one still waiting on redevelopment capital. The diligence file should note which comparables sit on which side of that line, since a lender's appraiser will ask the same question during underwriting.

Running the 45-Day Math on a Medical Building

The identification notice for a medical office replacement should name the address, the tenant-improvement balance, and the lease term left, well beyond a bare property description. Coordination with the qualified intermediary should confirm the notice language before day 45, and the investor's tax advisor should confirm how any remaining improvement balance interacts with depreciation recapture before the identification becomes irrevocable.

A second candidate held in reserve matters here specifically because medical tenant lease renewals can take longer to confirm than a standard commercial estoppel, since hospital-affiliated tenants often route estoppel requests through a system-level real estate office rather than a single practice manager, adding days to a process the 45-day clock does not pause for.

Common 1031 Exchange Questions

How many medical office properties should go on the identification list before the 45-day window closes?

Most exchangers name two to three candidates under the three-property rule so a financing or lease-review problem on the top choice does not force the exchange to fail. A single-property identification only makes sense when the tenant-improvement schedule and lease term are already fully documented.

What tenant-improvement numbers actually matter for a medical office exchange?

The remaining amortization balance on the buildout and the lease term left to absorb it matter more than the headline rent. A high rent with three years of term left against a ten-year TI amortization schedule is a weaker replacement than a lower rent with eight years remaining.

Does a single-tenant medical building carry more identification risk than a multi-tenant building?

It can, because the entire exchange outcome depends on one lease and one tenant's referral base. Multi-tenant medical buildings spread that risk across several leases, though they add more diligence line items for the qualified intermediary file.

How does block-by-block basis variance in Detroit affect a medical office replacement?

Two similar buildings a few blocks apart can carry different values depending on which side of a recovery corridor they sit on, and that gap changes how much of the START EXCHANGE REVIEW proceeds the replacement can absorb without leaving boot. The diligence file should document comparable sales from the same block rather than the same zip code alone.

Who confirms whether a medical office purchase satisfies like-kind requirements?

The investor's tax advisor and the qualified intermediary confirm like-kind treatment; this coordination work assembles the property facts and lease documents they need to make that confirmation, and does not itself give tax advice.
