A retrospective home appraisal for an estate in Upland, Montclair or Rancho Cucamonga values the house as of a past date, usually the date of death, using sales that had closed by then and the house's condition on that day. All three cities are in San Bernardino County, in the western Inland Empire, and each has a housing pattern that decides which past sales are comparable: Upland's historic districts and north-end view lots, Montclair's postwar tracts on the county line, and Rancho Cucamonga's foothill horse lots and planned villages.
What retrospective means in an estate file
A retrospective appraisal is an appraisal whose effective date, the date the opinion of value applies to, is in the past. In estate work that date is usually the date of death, the day the owner died. The date of report, the day the report is signed, is stated separately, so a reader always knows which date the value belongs to.
The method is the one used for a current value with the clock turned back. Comparable sales are those that closed on or before the date of death. Market conditions are read from that period. Condition is rebuilt as it was that day, because the house may since have been cleared, repaired, rented or sold. A later sale shows what the house brought later; it is not the date-of-death value.
The value developed is fair market value, the price at which the property would change hands between a willing buyer and a willing seller, neither under compulsion and both reasonably informed. The pillar article on date-of-death appraisals covers the method from the start.
Upland: historic districts, tracts and the north end
Downtown Upland carries designated historic districts, among them Magnolia, Pleasant View, Stowell and Victorian Row, along with the Euclid Avenue District. For an estate house there, district designation as it stood on the date of death is noted as a condition of the property, and comparables come from similar older blocks, not from the tracts. South of the 210, postwar and later tracts turn on additions, pools and garage conversions, each checked against its permit date. North of the 210, view and large-lot homes call for a wider comparable search with the reasoning stated.
Above the city, San Antonio Heights is unincorporated county land with horse-keeping and large lots: the same county assessor applies, city rules do not, and comparables are chosen for lot use. West Upland meets Claremont at the county line, and a Claremont sale is used only when it is genuinely better evidence, with the location adjustment explained. See the Upland area page.
Montclair: postwar tracts on the line
Montclair was incorporated as Monte Vista and grew mostly after the Second World War on former citrus land, so most estate houses here are single-story postwar tracts. They differ mainly in additions, garage conversions, lot size and condition, which makes the permit date of each addition the key fact: whether a converted garage counted as permitted living area on the date of death changes the gross living area, the finished above-grade living space, that the report compares.
Near the Montclair Transit Center and Montclair Place, estates sometimes hold duplexes or houses divided into units. The report states the legal unit count it relied on and the rents in place on the date of death. Montclair's western boundary, Mills Avenue, is the county line with Claremont and Pomona; a Los Angeles County sale can be valid evidence for a Montclair house only with the location difference explained. See the Montclair area page.
Rancho Cucamonga: foothill lots and planned villages
In Alta Loma and Etiwanda, many lots are larger, some zoned for horses, with trails through the neighborhoods. An estate horse property is compared with other horse-keeping properties that sold before the date of death, and barns, arenas and stalls are addressed for their contributory value, what each adds to the whole property in the market, rather than folded into one lump adjustment. The equestrian and large-lot appraisal page explains that analysis.
The planned villages, Victoria and Terra Vista among them, repeat floor plans, so comparables are matched plan to plan. Many areas carry a community facilities district special tax; where one applied on the date of death, the report notes it as a condition buyers weighed, sourced to the tax bill or the city's district information. Condominiums and townhomes are compared within similar projects with the HOA terms of that period. See the Rancho Cucamonga area page.
Evidence that carries a past date
- Listing or refinance photos taken near the date of death
- Permits and final sign-offs for additions, conversions, ADUs, pools and reroofs
- Dated contractor invoices showing what was replaced and when
- Family photographs from around the date
- Leases in place on the date, for any rented unit
- HOA documents and the tax bill showing any special tax
Where a fact cannot be confirmed, such as the condition of a kitchen remodeled after the death, the report relies on an extraordinary assumption, an assumption about uncertain facts that, if false, could change the result, and states it plainly so every intended user, the people entitled to rely on the report, reads the same limits.
Why an online estimate from the month of death is not the answer
An automated estimate from a portal is not an appraisal: an algorithm produced it from records and nearby sales without seeing the house. The county's assessed value is not an appraisal either. Neither shows the comparables, the condition on the date or the reasoning a CPA or attorney can review.
Who uses the report, and who decides
In a probate, the probate referee, a person appointed by the State Controller and designated by the court, appraises the house for the inventory under Probate Code section 8902; Probate Code 8900 in plain words explains that split. A successor trustee or the heirs order an independent report directly. For basis, IRS Publication 551 says inherited property generally takes its fair market value at the date of death, or on the alternate valuation date if elected, which is called stepped-up basis; your CPA decides which value is used. Section 8800 also has the personal representative certify a change in ownership statement in each county where the decedent owned property, here the San Bernardino County Assessor-Recorder-County Clerk. For an estate that also holds a Claremont, La Verne or Pomona house, the Los Angeles County estate article covers that side.
Next step
If you are settling an estate with a house in Upland, Montclair or Rancho Cucamonga, read how the estate and date-of-death appraisal is scoped, then send the date of death and the address, or call (909) 324-6122. The fee is set by the scope of the assignment and quoted before work begins, and the fee does not depend on the value. The rest of the series is on the estate and date-of-death hub.

Frequently asked questions
What is a retrospective home appraisal?
It is an appraisal whose effective date, the date the opinion of value applies to, is in the past. For an estate that is usually the date of death, and the appraisal uses sales that closed on or before that date and the house's condition then.
Can a date-of-death appraisal be done after the house has been sold?
Yes. The later sale shows what the house brought afterward and is not the date-of-death value. The appraisal is prepared as of the earlier date from listing photos, permits, invoices and other records of the house as it was.
How is a Rancho Cucamonga horse property valued as of the date of death?
With other horse-keeping properties that sold on or before that date, even when a tract house is closer, and with the contributory value of barns, arenas and stalls addressed item by item rather than in one lump adjustment.
Does a special tax in a Rancho Cucamonga planned village matter for an estate appraisal?
Where a community facilities district special tax applied on the date of death, the report notes it as a condition buyers weighed and sources it to the tax bill or the city's district information.
Who decides whether the date-of-death value is used for basis?
Your CPA. IRS Publication 551 sets out the general basis rule for inherited property, and the CPA decides which value is used and how. The appraisal documents the value and its reasoning; nothing here is tax advice.
