Selling a Long-Held Home Before Buying in Montebello: The Federal Gain Exclusion and Basis

Yes, for the buying side. Publication 551 says your basis includes the settlement fees and closing costs for buying property. Those amounts sit on top of the price you paid. A house bought long ago may therefore carry a higher starting figure than the purchase price alone. Find the settlement statement from that purchase before anyone works out the gain on the sale.

Publication 544 then carries the figure forward: original cost or other basis, increased by certain additions and decreased by certain deductions. The purchase closing costs are part of where that arithmetic begins. The older the purchase, the more the paper trail matters. Look for the closing statement, the deed file and anything the title company kept. Hand those to your tax adviser with the improvement records, so the house's adjusted basis is settled before the Montebello offer goes in.

Publication 544 for 2025 says increases to basis include costs of any improvements having a useful life of more than 1 year. Publication 551 states the same direction more briefly: if you make improvements to the property, increase your basis. Gather the records for each project on the house, and set each one against that useful-life wording before it goes into the figure.

Publication 544 describes adjusted basis as cost increased by certain additions, so not every dollar spent on a house is an addition. The useful-life test is the one it states for improvements. On a house owned for many years, the records tend to be scattered across invoices, contractor letters and bank statements. Sort them by year and keep them in one file. Your tax adviser decides which ones count, and the total feeds the gain the exclusion is measured against.

It can. Publication 523 for 2025 lists a condominium among the homes that each may be a main home and therefore qualify for the exclusion. May is the publication's word. The exclusion still applies only if you meet certain conditions, including the ownership requirement, which is counted back from the date of that later closing.

Montebello is a 98-unit condominium tower at 1100 Uptown Park Boulevard, so a home there falls in the condominium category Publication 523 names. Which conditions a particular unit meets is for you and your tax adviser to work through against Publication 523. Start the records on the day you buy. Publication 551 counts the settlement fees and closing costs for buying as part of basis, and those figures come out of the Montebello closing. File that statement with the resale certificate.

Publication 523 describes the exclusion as the first $250,000 of gain, raised to $500,000 for joint filers, if you meet certain conditions. Gain past the applicable figure falls outside the exclusion as the publication words it. That is why the basis of a long-held house deserves work: each addition Publication 544 allows raises the adjusted basis and so lowers the gain.

How any remaining gain is taxed is a question for your tax adviser, working from the publications themselves. Bring three things to that conversation: the purchase settlement statement, the improvement records, and the closing figures from the sale of the house. Publication 544 measures gain from the amount you realize on the sale. Keep the final settlement statement from the house closing with the rest of the file, so the sale side and the basis side sit together.

Publication 523 looks at a window rather than a lifetime. The requirement is met by owning the home at least 24 months out of the last 5 years leading up to the date of sale. The publication treats that date as the date of the closing. Ownership is only one of the conditions, so read the others in Publication 523 before relying on the exclusion.

A long ownership is read only through the day the house sale closes. A delay in that closing moves the end of the window with it. If you are lining up a Montebello purchase, keep the ownership dates from the deed and the planned closing date together. Take both to your tax adviser before either contract is signed.
