For a primary residence, there is no time limit to reinvest money, as you can exclude up to $ 250 , 000 $ 2 5 0 , 0 0 0 (single) or $ 500 , 000 $ 5 0 0 , 0 0 0 (married) of gain if you lived there for two of the last five years. However, for investment properties, a 1031 exchange requires identifying a new property within 45 days and closing within 180 days.
If you sell your house and don't buy another, you'll have cash proceeds (after paying off the mortgage and selling costs) and need to decide on new housing, often renting or moving in with family; financially, you might benefit from the IRS capital gains exclusion (up to $250k/$500k profit if you've lived there two of the last five years), but you'll pay tax on gains beyond that, while also managing the new costs of renting or storage.
The seller must have owned the home and used it as their principal residence for two out of the last five years (up to the date of closing). The two years don't have to be consecutive to qualify. The seller must not have sold a home in the last two years and claimed the capital gains tax exclusion.
To obtain this tax exemption on your capital gains, you should invest the sum earned in bonds within 6 months of the transfer of the sum and realization of gains. In addition to this, the funds are required to be invested in these bonds for a minimum of three years as a lock-in period.
The "3-3-3 rule" in real estate isn't a single guideline but refers to different strategies: for buyers, it's about financial readiness (3 months savings, 3 months reserves, 3 property comparisons) or a financial affordability check (30% income, 30% down, 3x income); for agents, it's a marketing habit (call 3, note 3, share 3) or prospecting (talking to everyone within 3 feet). There's also a developer rule (1/3 land, 1/3 build, 1/3 profit), though it's considered outdated by some.
As long as you sell your first investment property and apply your profits to the purchase of a new investment property within 180 days, you can defer taxes.
On a $100,000 capital gain, you'll likely pay 15% for long-term gains, resulting in about $15,000 in federal tax (plus potential state tax), but it could be 0% or 20% depending on your total taxable income and filing status, while short-term gains are taxed as ordinary income (potentially 22-24%).
Contrary to what many people believe, there's no immediate requirement to buy another house to avoid tax penalties. The capital gains tax exclusion is not dependent on you purchasing another home right away.
The "12-month rule" for capital gains tax in the U.S. distinguishes between short-term and long-term gains: assets held for one year or less result in short-term gains, taxed at your higher ordinary income tax rates, while assets held for more than one year (over 12 months) generate long-term gains, taxed at lower, preferential rates (0%, 15%, or 20%). This rule determines if your profit gets taxed as regular income or at a reduced rate, making holding assets longer generally more tax-advantageous.
The 20% rule for capital gains refers to the highest federal tax rate for long-term capital gains, applying to higher income brackets when you sell investments (stocks, real estate) held for over a year, with lower rates of 0% and 15% for lower incomes, and even higher rates for special assets like collectibles. This rate kicks in for single filers earning over approximately $492,300 (2024) or $533,401 (2025), and higher for joint filers, making holding assets over a year a key tax strategy.
Yes, you can absolutely sell a home below market value—and legally gift the difference. It's a legitimate and frequently used estate planning strategy that can support younger generations, avoid probate, reduce capital gains, and reduce estate tax exposure.
When you sell your primary residence, $250,000 of capital gains (or $500,000 for a couple) are exempted from capital gains taxation. This is generally true only if you have owned and used your home as your main residence for at least two out of the five years prior to the sale.
If you use your former home to produce income (for example, you rent it out or make it available for rent), you can choose to treat it as your main residence for up to 6 years after you stop living in it. This is sometimes called the '6-year rule'. You can choose when to stop the period covered by your choice.
The five-year rule
This has to do with the amount of equity the average homeowner has built in their home after five years of possession, and it also takes into account the costs associated with selling a home (and, if applicable, with purchasing a new one).
You don't have a strict timeline to buy another home to avoid capital gains on your primary residence; instead, you must meet the IRS's "2-out-of-5-year rule" for ownership and use of the sold home, allowing you to exclude up to $250k/$500k profit, but you can't use the exclusion again for two years if you sold another home recently, while deferring taxes on investment property requires a strict 45/180-day timeline for a 1031 exchange.
It allowed sellers to claim CGT exemption for the final 36 months of ownership, even if they had moved out. However, this was reduced to 18 months in 2014 and further to 9 months in 2020, which remains the rule today. This general law is in place as it prevents short-term transaction benefits concerning taxation.
