What's my Twin Falls home worth? Assessed value, market value and getting a local range
Twin Falls County sends every owner an assessment notice with a value on it. When you sell, a buyer decides what the home is worth to them. Here's how those two numbers relate, how Twin Falls County's review and appeal steps work (including for newly built homes), and how to get a local range before you list.
Get a local value range: a local expert sends you a price range for your home. It isn't an appraisal, and you don't have to list to get one. No obligation.

Assessed value vs. market value
Idaho assesses property every year at market value as of 12:01 a.m. on January 1 (Idaho Code §63-205). Twin Falls County's treasurer FAQ puts the appeal question the same way: does your assessed value reflect your property's market value on January 1, before the homeowner's exemption is subtracted (Twin Falls County, Treasurer FAQ)?
A sale price can be different because:
- It's a different day. The notice looks back to January 1. A buyer pays on the day you sell.
- The record has limits. The notice shows what the county has on file. Your notice is your yearly chance to review ownership, assessed value and exemptions, and to catch errors (Twin Falls County, Understanding Your Assessment Notice).
- Buyers see inside. Condition and recent updates show up on a tour, even if they aren't on the county record.

Your Twin Falls County assessment notice
The Twin Falls County Assessor's office is at 630 Addison Ave. W., Suite 1300, on the first floor of County West in Twin Falls (Twin Falls County Assessor).
When notices arrive. Twin Falls County sends assessment notices on or before the first Monday of June. Newly built homes get theirs once they're finished and occupied, from mid-July through February of the next year (Twin Falls County).
Step 1: Property review. The county says the first step is an informal meeting with one of its Certified Appraisers, sometimes by phone or email. Use it to check the facts on your property record, understand how your value was estimated, see whether it's fair compared with similar homes nearby, and find out if you qualify for exemptions. The county says most disputes are resolved here (Twin Falls County, Property Value Appeals).
Step 2: Board of Equalization. If you still disagree, file a written appeal on a form from the County Commissioners' office. The commissioners serve as the Board of Equalization. The deadline is 5:00 p.m. on the fourth Monday in June. For 2026, that was June 22 (Twin Falls County Assessor; Idaho Code §63-501A). For most assessments, the board hears appeals between the fourth Monday in June and the second Monday in July.
Step 3: State appeal, if needed. You can appeal a board decision to the Idaho Board of Tax Appeals within 30 days, by filing a notice of appeal with the county clerk (Idaho Board of Tax Appeals).
Two things to keep in mind: the appeal is about value, not about taxes being too high, and you can appeal only when notices go out each June.
Homeowner's exemption deadline. If you own and live in your Twin Falls County home as your primary residence and haven't applied for the homeowner's exemption, applications for the 2026 reduction must be received by December 31, 2026. If you moved into a newly built home, the county says the deadline differs, so contact the Assessor when you move in (Twin Falls County Assessor; 2026 Assessment Mailer). The Idaho homeowner's exemption explains how it works.
What buyers pay for
A buyer walking through your Twin Falls home is weighing:
- Condition: roof, heating and cooling, water heater, windows, and how the home has been maintained.
- Updates: kitchen, baths, flooring and systems, and when the work was done.
- Size and layout: finished square footage, bedrooms and baths, and how the rooms work together.
- Yard, garage and outdoor space: garage or shop space, RV or extra parking, fencing, landscaping and sprinklers.
- Recent nearby sales: similar homes that sold close by, and the homes for sale a buyer can pick instead.
City pressurized irrigation. Many Twin Falls subdivisions water yards with pressurized irrigation from canal water. The city runs the pump stations, the main lines and service lines up to the first shut-off valve; you maintain the filter and sprinkler system after that valve, plus any ditches on your property. The city bills for it monthly through the year. The water is untreated and isn't for drinking (City of Twin Falls, Pressure Irrigation). The city's subdivision status page shows which pump station serves your subdivision. Buyers ask, so have those details ready.

FAQ
- How do I find out what my Twin Falls home is worth?
Review your Twin Falls County record, compare similar homes for sale in Twin Falls, or request a local value range on the BrowseIdaho homepage. A local expert sends a price range. No obligation.
- Is my assessed value what my house would sell for?
Not necessarily. Idaho assesses property at market value as of January 1 (Idaho Code 63-205). A sale price reflects condition, updates and the market when you sell.
- How do I appeal my Twin Falls County assessment?
Start with a property review with a county appraiser. If you still disagree, file a written appeal with the Twin Falls County Board of Equalization by 5:00 p.m. on the fourth Monday in June. Notices go out on or before the first Monday of June; newly built homes get notices after they're finished and occupied.
- Do home improvements raise value?
Some do. Buyers pay for condition and updates, but not every project returns what it costs. Repairs an inspector would flag are a good first step.
- Does the homeowner's exemption change my value?
No. Your market value stays the same. The exemption reduces the taxable value of a home you own and live in as your primary residence. In Twin Falls County, apply by December 31; newly built homes have a different deadline.
- Can I sell my Twin Falls home without an agent?
Yes. You can price, show and sell your own home. The table above shows what you can do yourself and what a local expert handles at each step.
