DOWNSIZING IS A PRICED DECISION. AGING IN PLACE IS NOT THE BROKER'S CALL.

The first is the federal exclusion: up to $250,000 of gain on a principal residence, $500,000 on a joint return when one filer meets the ownership test, both meet the two-year use test and neither used the exclusion in the prior two years (VERIFIED, 26 U.S.C. 121). The second is the Colorado senior exemption: 50 percent of the first $200,000 of actual value off the roll for an owner 65 or older who owned and occupied the home for 10 consecutive years, and it ends when the property sells (VERIFIED, C.R.S. 39-3-203). The third is the property tax deferral for owners 65 and older, a state loan secured by a lien that is due when the home sells (VERIFIED, C.R.S. 39-3.5).

The exemption line is the one that changes the decision. A smaller place bought after the sale does not carry the old exemption with it until the ownership and occupancy test is met again on the new address (PROBABLE as applied; the county assessor confirms). That is a monthly cost of moving, and it belongs on the sheet before the list price does.

The third discipline compares selling with keeping the house. The rent-vs-sell tool on /tools/rent-vs-sell prices selling now against renting the house for a chosen period and selling later. An owner who is not sure the move is right can run both and see the gap in dollars before talking to anyone (PROBABLE, the result depends on the inputs you choose).

Buying the next place before selling this one is its own question. The move-up tool on /tools/move-up prices both orders, and the existing answer on buying first or selling first in Colorado walks through the deadlines. Denver metro median days on market was 57 days in August 2026, and that clock runs to contract, not to closing (VERIFIED, FRED MEDAONMAMSA19740).

The evidence that the method is real is public. Robert An is a broker associate at Compass, Colorado license 100084328, licensed since 2019. The record is 5.0 across 32 Zillow reviews and 54 recorded sales, 18 in the last twelve months (VERIFIED, Zillow profile, read 2026-09-24). The fit page /is-homesy-right-for-you says the practice fits someone who wants the risk laid out in writing before deciding and who wants to be told to wait, and fits less well for someone who reads risk-framing as alarm.

The first step is one address. Robert reads the house and comes back with the three biggest open questions, the tax lines that apply and the net on each exit. The decision to move stays yours, and the guide's handout at /handouts/downsizing is the portable copy to read at the kitchen table.
