Updated September 2026 with FLYP's current project figures.
The short answer
Two federal rules set your calendar: the home sale exclusion and the two-of-five-year ownership and use test. For most Puget Sound downsizers the tax conversation is a federal one, because Washington has no income tax and its capital gains tax does not reach real estate. The sequence that usually works best is to buy, move, renovate the empty house, then list it.
Everything below is general information, not tax advice. Before you change the calendar or the ownership of anything, run the numbers with a CPA.
Start with the two rules that set your calendar
The first is the home sale exclusion. Per IRS Publication 523, a single filer may exclude up to $250,000 of gain on a principal residence and a married couple filing jointly up to $500,000. The second is the test that unlocks it: you generally have to have owned the home and used it as your main home for at least two of the five years ending on the date of sale.
Publication 523 is explicit that the residency requirement is not a single block of time. The 24 months of residence can fall anywhere within the five-year period. For a married couple filing jointly, only one spouse has to meet the ownership requirement, but each spouse has to meet the residence requirement individually.
There is also good news specific to this state. Washington's capital gains tax does not apply to the sale or exchange of real estate, and the Department of Revenue says it does not matter how long the seller owned the property, whether the seller occupied it, where it is located, what type of property it is, or who owns it. Washington also has no personal income tax.
What actually counts as your gain
Your gain is not your sale price. It is the sale price minus selling costs minus your adjusted basis, and basis is where a 30-year owner usually leaves money on the table. The additions you paid for over three decades, the new roof, the deck, the remodeled bath, the sewer line replacement, generally add to basis. Publication 523 includes a basis worksheet for exactly this purpose.
Two practical implications:
- Dig out the old receipts and permits now, while you are already going through the house. A shoebox of old invoices is worth real money if your gain is close to the exclusion limit.
- Money you spend on the pre-sale renovation is part of this picture too. Keep the signed contract, the change orders and the final invoice, and hand them to your CPA.
If your gain exceeds the exclusion, the excess is taxable at federal long-term capital gains rates, and higher-income sellers can also face the net investment income tax. Your CPA can tell you which brackets you land in and whether the timing of the sale, this December or next January, changes the answer.
The trap: moving out and renting the house
This is the most common expensive mistake for empty-nesters. You buy the smaller place, you move, the old house sits there, and someone suggests renting it out "until the market improves."
The five-year lookback ends on the date of sale. Once you move out, you have roughly three years of slack before your 24 months of qualifying use falls out of the window entirely. Rent it for four years and sell in year five, and you may have no exclusion at all. On a long-held Seattle-area house, that is not a rounding error.
There is a nuance worth knowing, because it cuts in your favor. Under Internal Revenue Code section 121, a period of nonqualified use does not include any portion of the five-year period that falls after the last date the property was used as your principal residence. Renting after you move out therefore does not force you to allocate a slice of your gain to nonqualified use the way renting before you moved in would. It does not extend the two-of-five clock, though, and depreciation you claim while it is a rental gets its own treatment. Both of those are CPA questions.
Two more provisions matter to this reader. Section 121 also carves out any other period of temporary absence, not to exceed an aggregate of two years, due to a change of employment, health conditions or other unforeseen circumstances. And Publication 523 says that if you are a surviving spouse who does not meet the two-year ownership and residence requirements on your own and you have not remarried at the time of the sale, you may include any time when your late spouse owned and lived in the home.
Five questions to bring to your CPA
- Based on my purchase price, my improvements and my expected sale price, what is my estimated gain, and how much of it is covered by the exclusion?
- If I move out in October and sell in April, does anything change?
- What happens to my exclusion if I rent the house for a year first, and what does depreciation do to the result?
- Which renovation and selling costs adjust basis, and what documentation do you want?
- If I am widowed, what do the surviving spouse rules do to my exclusion amount and my basis?
What 30 years looks like to a 2026 buyer
Buyers walking through a long-held home are not grading your housekeeping. They are pricing risk. In older Puget Sound housing stock, the risk list is usually the same short list, and it is worth getting ahead of it before anyone writes an inspection response.
Systems and structure, first:
- Roof age and moss, gutters, downspouts that dump against the foundation, and grading and drainage in general. This is the Northwest. Water management is the whole ballgame.
- Water heater and furnace age. Original knob and tube wiring, an undersized or recalled panel, ungrounded outlets.
- Galvanized supply lines, and the side sewer. A sewer scope is cheap and a failed one is not.
- Crawlspace vapor barrier, insulation, evidence of rodents, and any dry rot at decks, trim and window sills.
- Unpermitted work. A finished basement or converted garage with no permit history is a negotiation the buyer will win.
Cosmetics, second, because they are what the photos sell:
- Interior and exterior paint, in current neutrals rather than dated palettes.
- Flooring, lighting and hardware, which date a house faster than anything except a kitchen.
- Kitchen and primary bath, the two rooms where "original" costs you the most in buyer imagination.
Be skeptical of payback percentages
Anyone who tells you a specific project will return a specific percentage is guessing on your behalf. Payback varies by neighborhood, price band and what the competing listings look like that month. Zonda's Cost vs. Value Report, the table most often quoted at sellers, estimates resale value from surveys of real estate professionals plus an econometric model rather than from matched sales, so its percentages are informed opinion and not transaction data.
What we can tell you is our own underwriting, with the caveats attached. Across the 12 homes that had both an as-is value and a projected after-renovation value, out of 16 homes FLYP had underwritten as of September 2026, the projected lift over as-is value had a median of 27 percent and a range of 1 percent to 89 percent. Projected dollars added had a median of $190,000.
Those are projections made during underwriting, not sale results, and no FLYP home has sold yet. Several of those files project almost no lift at all. Your house is not the median.
Move first, then renovate, then sell empty
For a downsizer, the cleanest sequence is usually: close on the smaller place, move, then renovate the empty house, then list it. An empty house is faster and cheaper to renovate than an occupied one, and you are not living in drywall dust.
| Renovate while living there | Move first, then renovate | |
|---|---|---|
| Disruption | High, and it lasts for weeks | Almost none |
| Crew efficiency | Slower, phased around you | Faster, full access |
| Staging and photos | Around your furniture | Clean slate |
| Carrying costs | One house | Two houses for a stretch |
| Tax clock | No move-out yet | Move-out date starts the three-year runway |
Two cautions. Call your insurer before the house sits empty, because vacancy provisions in a standard homeowners policy are not the same as occupancy. And if the plan requires buying before selling, talk to your lender early about how they will treat the existing mortgage.
When the equity is large but the cash is committed
This is the specific bind for downsizers. Your net worth is in the old house, and your cash is in the down payment on the new one. Nobody wants to write a renovation check two months after writing a check for a condo.
That is what a pay-at-closing renovation is for. FLYP plans, funds and manages the pre-sale work, and the renovation is performed by Green State Restoration, LLC, a licensed and insured Washington general contractor. The terms, stated plainly:
- $0 upfront, $0 during the work, no monthly payments. You repay out of closing.
- What is repaid is the fixed contract price on the signed estimate, plus Washington sales tax, plus any change orders you signed, plus the county recording fee. There is no program fee and no percentage of the sale.
- No interest during the renovation and none for six months after the work is finished. After that, the balance accrues 1.5% per month, and paying it off early stops the interest.
- Ten months after the work is finished, the balance is due directly, whether or not the home has sold.
- The balance is secured by a deed of trust recorded against the property, signed before an independent notary before work starts, and released within ten business days of payoff.
- One-year written workmanship warranty. The full plain-language contract summary is at how the process works.
You can lose money or equity. The market can move, the house can sell for less than projected, and interest can accrue after the six-month window. FLYP also applies a coverage test: projected net proceeds, meaning the projected after-renovation value less selling costs and less the balance of every senior lien, divided by the maximum amount that could ever become payable to FLYP, has to be at least 1.30. That is an underwriting safety margin, not a return and not a promise.
This is the wrong tool if: you have cash or a low-rate HELOC already in place and are comfortable using it, you plan to hold the house as a rental rather than sell, your timeline to list is genuinely open-ended, or the house needs so little that paint and a deep clean would do it. If you would rather skip the work entirely, we can also help arrange an as-is cash offer, with terms that depend on the property.
Budget for the excise tax, and watch the 2027 change
Most Puget Sound downsizers do not leave the state. They move to a smaller home nearby, to a single-level place in a quieter county, or closer to adult children on the other side of the water.
Washington charges a graduated state real estate excise tax, usually paid by the seller, and the Department of Revenue says the thresholds are adjusted every four years under RCW 82.45.060. The current thresholds, set in 2023, tax the state portion at 1.1% on the price up to $525,000, 1.28% up to $1,525,000, 2.75% up to $3,025,000 and 3.0% above that. For sales beginning January 1, 2027, the same page lists the thresholds moving up to $551,000, $1,551,000 and $3,051,000, with the rates unchanged.
Cities, counties and towns add a local REET on top of the state portion. Check the current brackets and your location code on the Department of Revenue page, have your escrow officer confirm the local rate for your address, and if a sale could land on either side of January 1, 2027, ask your CPA whether the timing changes your bill.
On seasonality, if the last kid just left in August, you are choosing between a fall listing and a spring one. A fall listing means a compressed prep window. A spring listing gives you the whole winter to do the work, which is usually the better trade for a house that needs systems attention, as long as you are honest with yourself that the work will actually start in November and not February.
The bottom line
Protect the two-of-five-year clock before you do anything else, because renting the old house for a few years is what most often costs a downsizer the exclusion. Gather the improvement receipts, get a CPA to price the gain, and then pick the sequence. Move first, renovate empty, list clean is the sequence that usually costs the least in disruption and time.
If you want to know what your house would need and what it would cost before you commit to a sequence, get started here and we will walk the house and put a fixed-price scope in writing. No obligation, and no pressure to renovate if the answer is that paint and a sewer scope are enough.
