Before selling a rental: build the property’s tax-basis bridge

Establish the starting basis and ownership history

Locate the final purchase closing statement, contract, deed and records supporting the allocation among land, building and separately tracked assets. Certain costs of buying the property belong in basis; loan costs, prepaid items and escrow deposits need different treatment. The down payment is not the entire purchase basis, and later principal payments do not buy the property a second time.

If you inherited the property, received it as a gift or acquired it through an exchange, identify that before using a purchase-price worksheet. Publication 551 describes different starting-basis rules. List the owners and any ownership changes; selling real estate is not the same transaction as selling an interest in the entity that owns it.

• Rebuild the original acquisition file if closing records are missing

Build a basis bridge with an evidence column

Make a dated schedule for each asset, not just one total called “the house.” Start with its original cost or other basis, add qualifying capital adjustments and subtract depreciation and other required reductions. Keep the source document beside each entry and flag missing amounts. A county assessment or current mortgage balance is not a substitute for this history.

Track improvements separately with their cost and placed-in-service dates. Do not add a repair to basis after already deducting it as an operating expense. Review insurance reimbursements, casualty adjustments, credits, partial dispositions and prior exchanges where relevant; a simple purchase-plus-projects total can miss them.

• Use project records to distinguish repairs from capital improvements
• Connect the last annual file to the sale-year records

Illustration: adjusted basis, gain and cash are different numbers

Hypothetical record-bridge example—not a tax-liability estimate. Assume a wholly owned property was purchased for rental use, never used personally, and has no exchanges, casualty adjustments or other basis changes. The documented purchase price is $300,000, eligible acquisition costs are $6,000 and capitalized improvements total $24,000. Depreciation allowed or allowable through the sale is assumed to total $60,000, excluding land. The combined adjusted basis is $270,000: $300,000 + $6,000 + $24,000 − $60,000.

Assume an ordinary cash sale for $400,000 with $24,000 of qualifying selling expenses and no other closing adjustments. Amount realized after those expenses is $376,000. Subtracting $270,000 adjusted basis gives $106,000 of gain for further analysis—not $106,000 of tax. If $180,000 of mortgage principal is paid off at closing, cash remaining before income tax is $196,000: $376,000 − $180,000. That payoff does not reduce the $106,000 gain.

These aggregate figures are a reconciliation checkpoint. The preparer still needs allocations among land, building and other assets, the actual depreciation through disposition and the rules that determine each portion’s treatment. A real settlement statement can also contain rent, deposits, taxes and other items that should not all be called selling costs.

Resolve depreciation and prior personal use before estimating tax

Get the full depreciation schedules from prior preparers or software, including assets no longer obvious in the current ledger. Publication 551 requires basis reductions for depreciation allowed or allowable; a missed deduction is not permission to ignore depreciation at sale. Ask how missing or incorrect years should be corrected rather than silently inserting zero.

There is no universal single “depreciation recapture rate” for every rental-sale dollar. Publication 544 distinguishes ordinary-income recapture on certain depreciable assets from unrecaptured section 1250 gain associated with depreciated real property. Building, land and separately depreciated items can have different treatment; holding periods and other gains or losses also matter. Do not multiply all accumulated depreciation or the entire gain by one assumed rate.

If the property was once your home, preserve both the pre-conversion adjusted basis and fair market value at conversion. The depreciation starting basis is generally the lower amount, excluding land, but a later gain or loss can require different basis calculations. Personal occupancy dates, rental periods and any home-sale exclusion question need their own review; prior residence does not automatically make the whole gain excludable.

• Recover the conversion timeline and value evidence for a former home

Take the proposed transaction in before committing to terms

Bring the expected price, estimated selling costs, ownership arrangement, proposed closing date and draft terms. Include federal and state prior returns, depreciation detail and suspended-loss schedules. Ask separately about gain character, any release of suspended losses, state treatment and tax-payment planning. North Carolina property can create a North Carolina filing question even for a nonresident, subject to the applicable requirements.

Raise an exchange, installment sale, related-party transfer or entity-interest sale before signing or closing. Those are not ordinary cash-sale variations that this illustration resolves. Ask which requirements, deadlines and other professional roles the actual transaction needs.

After closing, replace estimates with the final settlement statement, payment evidence and any information return received. Reconcile the last rent collection, tenant-deposit transfer, expenses and depreciation through the disposition. Keep the final sale calculation with the permanent basis history and confirm which documents remain outstanding.
