Prepare the financing and exchange team before the sale closes. The practical goal is to know what you can buy, what the lender will accept and where the remaining cash will come from while there is still time to change course. Identification alone is not loan approval.
When do the periods start?
For the ordinary deferred exchange discussed here, the transfer of the relinquished property starts both periods. The 180 day period does not begin after the forty five day identification window.
Have the qualified intermediary and tax adviser establish the actual transfer event, relevant dates and any applicable special rules. Multiple relinquished properties, disaster relief, return filing timing and other circumstances can require additional analysis.
IRS instructions also address the earlier tax return due date, including extensions. [1] Do not assume 180 days is always the controlling end date. A tax filing extension and a purchase contract extension serve different purposes.
The regulation contains detailed identification and exchange requirements. [2] Your intermediary and counsel should explain the accepted identification method and limits rather than relying on a verbal list sent to the real estate agent.
An illustrative calendar
Assume a single relinquished property transfers on May 1, 2026, with no special timing relief and no earlier controlling return due date. Forty five days later is June 15, 2026. The 180 day date is October 28, 2026.
These are arithmetic illustrations, not a determination of anyone's exchange dates. The exchange professionals must verify the actual event, documents and applicable rules.
If the investor identifies a property on June 15, the financing team does not then receive another 180 days. If that property fails underwriting in September, the remaining options depend on the valid identification, contract and exchange rules already in place.
Plan around a funding target earlier than the last possible day. Final documents, payoff corrections and wire instructions can require work after the main underwriting review is complete.
Put two schedules side by side
| Stage | ** Exchange or tax work** | ** Financing and cash work** |
|---|---|---|
| Before relinquished closing | Establish the exchange team and handling of proceeds | Review borrower, budget, probable property types and outside liquidity |
| Early identification period | Evaluate permitted identification choices | Screen properties, legal use, insurance, rent and lender fit |
| Before identification ends | Complete valid identification under the rules | Understand which properties have realistic financing and cash paths |
| Acquisition period | Preserve the required structure and records | Complete appraisal, title, underwriting and source verification |
| Before receipt deadline | Confirm accepted acquisition and exchange documentation | Fund on time with correct ownership and disbursements |
The tax schedule sets legal requirements; the financing schedule identifies work needed to close. Progress on one does not prove the other is ready.
Prepare before the relinquished property sells
Ask a lender to review the expected borrower, ownership, credit, income or rental qualification route, existing obligations and available reserves. This is not a substitute for property approval, but it can identify obstacles before the clock starts.
Estimate net exchange funds using the actual payoff and projected sale adjustments. Separately identify outside cash for costs, funding gaps and liquidity. A gross sale price is not the amount the intermediary will receive.
Set up the exchange arrangement before sale proceeds are handled. IRS guidance explains the risk of actual or constructive receipt and the qualified intermediary safe harbor. [3] Do not assume the closing agent can correct a personal receipt of funds after the fact.
Review likely property exclusions with the lender: condition, occupancy, association restrictions, unusual collateral and other matters that could prevent financing. This article covers coordination across financing routes. For DSCR specific execution, see 1031 purchases with DSCR financing.
Screen replacements before identification
Give the lender enough property information to assess eligibility. Obtain the address, type, unit count, intended use, price, lease or income evidence, likely taxes and insurance, and any association information.
Arrange inspections and title review through the proper professionals. A short identification window is a reason to organize the work early, not to skip evidence about a building or its permitted use.
If financing is uncertain, have the adviser evaluate identification of permitted alternatives under the rules. An extra property mentioned informally is not automatically a valid backup, and identification limits can matter. The intermediary should document what has actually been identified and accepted under its process.
Coordinate contract protections with the real estate professionals and counsel. Tax identification and a purchase contract are related but different commitments. A property can be identified without every financing and contractual issue being resolved.
Appraisal, insurance, title and underwriting
Order lender required valuation promptly after confirming the property fits the intended product. Establish tenant access, report delivery, rent support and any review product. A faster appraisal is not helpful if the lender later discovers the property type is excluded.
Obtain insurance terms while the property can still be evaluated. Coverage, premium, deductible and project requirements can affect both qualification and cash needs. Do not use the seller's premium as the buyer's final cost.
Have title investigate ownership, liens, legal access and vesting early. An unreleased mortgage or estate issue can outlast the credit review. Share material findings with the lender and exchange team as soon as they are known.
Submit borrower and funds documents as one complete package where possible. Ask for a written list of remaining conditions and who owns each one. Track approval, document preparation, settlement and funding rather than using appraisal ordered as a general status for the whole loan.
A late loan reduction example
Assume a hypothetical replacement costs $600,000. The plan uses $250,000 of exchange funds and a $350,000 purchase loan, covering the price. Separate accepted funds cover costs and reserves under the original plan.
If underwriting reduces the loan to $320,000, another $30,000 must fund the price. The lender needs an accepted source, the settlement team needs revised figures and the tax adviser needs to review any changed exchange consequences.
Suppose the reduction is discovered on October 15 in the illustrative calendar above, leaving thirteen days until October 28. A new lender promising a quick review may still need valuation, disclosures, title and funding. Switching does not create a new exchange period.
A preplanned accepted cash source or a properly structured alternative may preserve options. Whether another identified property or financing route can work needs a real review within the actual rules and dates. Neither an emergency quote nor an unverified loan promise is a dependable backup.
Financing changes need coordinated review
A new loan amount, buyer entity, property price or funds source can affect more than underwriting. Tell the intermediary, counsel and tax adviser before approving a change in ownership or disbursements.
A smaller replacement mortgage is not automatically a failed exchange, and a mortgage matching the old balance is not automatically sufficient for the tax result. The debt replacement guide separates liabilities, equity and outside cash.
If an expected source is unavailable, calculate the actual shortage. Do not move restricted exchange money into a personal account or change descriptions to make the file appear funded. Have the professionals identify a permitted solution and document it accurately.
Assign clear roles
The intermediary coordinates its exchange documentation and funds responsibilities. The CPA evaluates tax qualification, reporting and the economic consequences of changes. Counsel reviews legal structure and contractual rights. The lender approves the credit and collateral transaction. The settlement team coordinates accepted documents and disbursements.
Choose one shared calendar and contact list. Each update should identify the changed fact, affected deadline, responsible person and next action. A message saying closing looks good is less useful than confirmation that the final insurance, title condition and verified cash are accepted.
The borrower remains responsible for timely decisions and complete records. A deadline is not satisfied simply because a professional was asked to work on the matter.
Questions for the CPA and intermediary
Ask the CPA and intermediary:
When do the periods begin, and which receipt deadline controls?
Does any specific timing relief apply?
What identification method, limits and alternatives are permitted?
What happens if an identified property falls through?
Ask how actual sale proceeds, payoff, replacement debt, expenses and outside cash affect the exchange analysis. Discuss ownership and taxpayer identity before a lender proposes an entity for convenience.
Have the advisers explain the result if the exchange cannot be completed. That helps compare a costly emergency financing plan with the tax and cash consequences of a different outcome. The decision should use figures, not a general instruction to close at any cost.
Records and a realistic funding buffer
Relinquished sale agreement, settlement statement and exchange agreement.
Dated identification, delivery evidence and intermediary statements.
Replacement contract, amendments and final acquisition statement.
Lender approvals, valuation, insurance, title conditions and source records.
Budget for a delay within the permitted period: another appraisal, an extension charge, a lower loan or additional carrying expense. Confirm the loan's maturity and prepayment terms so an emergency closing does not create a worse exit shortly afterward.
Tax advice boundary: Exchange deadlines and qualification require the intermediary, CPA and counsel to evaluate the actual transaction. A mortgage adviser can coordinate financing requirements but cannot extend tax periods or certify exchange treatment.
Bring Dane the verified exchange dates, expected funds and replacement details early. The aim is a financing plan that leaves time to resolve a real problem before the exchange's final days decide the outcome for you.
