UAD 3.6 series Part 6 of 7

The Signal / UAD 3.6 / October 17, 2026

The grid shows its workComparable Weight, time adjustments and the comps left out under UAD 3.6

The UAD 3.6 sales comparison grid records three things the legacy 1004 never had a field for: how much the appraiser relied on each comparable, a time adjustment tied to each contract date, and the properties considered and set aside. A reviewer can now read that reasoning as data.

The Sales Comparison Approach is the longest chapter in the GSEs’ reference guide to the redesigned URAR, pages 214 to 282 of 378.1 Most of what changed for collateral review sits in its grid.

This is Part 6 of our UAD 3.6 series. Part 1 covered how the report decides its own shape; this part stays inside the grid. It walks through the GSE sample reports’ actual numbers: SF1, a single-family house with three comparables and five properties it analyzed and did not use, and a four-unit sample whose time adjustments run about 1% a month.34 Part 7 picks up where this one stops, at the reconciliation of the whole report.

01 / A grid that changesFixed rows to conditional rows

From 18 printed rows to a grid that adds rows when the property needs them

Page 2 of the legacy Form 1004 prints 18 feature rows, from Sale or Financing Concessions to Porch/Patio/Deck, and 3 blank numbered lines for anything else. Every property got the same rows. The page has no row for how much each comparable counted and no place to record a property the appraiser looked at and set aside.5

The URAR grid is built from up to 12 subsections. Seven always display; the others appear when the facts call for them, such as Project Information for a condominium or Water Frontage with Private Access for a lakefront house.1

Legacy Form 1004 page 2 sales comparison grid: fixed rows for Location, View, Design, Quality, Age, Condition, Room Count, Gross Living Area and others, three blank numbered lines, and Net and Adjusted Sale Price rows. There is no weight row.

The GSEs publish every possible grid row in a companion workbook, with three flags: whether the row always displays, displays if applicable, or may display when relevant, and whether it can carry an adjustment.2 Counted across the workbook, the grid has 151 rows. Only 31 always display, and 67 can carry an adjustment.

02 / Time adjustmentsThe Contract Date row

The time adjustment now sits on the Contract Date row

The legacy grid had one row, Date of Sale/Time. The URAR splits it into Contract Date (22.01.30) and Sale Date, and the market-change adjustment goes on the Contract Date row. F-1’s note is direct: “If Contract Date is known, use this row to make time adjustments based on changes in the market.”1 A pending comparable has a contract date too, so it gets the same treatment as a closed sale.

Fannie Mae’s policy asks the appraiser to determine whether market conditions changed “from the time the comparable went under contract to the effective date of the appraisal report.” Support can come from home price indices, statistical analysis, modeling or paired sales, and the report “must, at a minimum, summarize the supporting evidence and include a description of the data sources, tool(s), and technique(s) used.” If the contract date is unavailable, the appraiser enters unknown.7

SF1 grid General Information: contract dates 07/22/2019, 08/05/2019 and 07/02/2019 for the three comparables, each with a $0 adjustment, against the subject's 09/17/2019 contract.
SF1: three $0 adjustments. Contracts 46 to 80 days before the 09/20/2019 effective date. Source: SF1 v1.4, PDF p. 14.3
Scenario 2 grid General Information: contract dates 03/26/2023, 12/22/2022 and 02/25/2023 with adjustments of $10,000, $30,000 and $15,000.
Scenario 2: $10,000, $30,000, $15,000. The reconciliation says “approximately 1% per month for each comparable.” Source: 2- to 4-unit Scenario 2 v1.2, PDF pp. 16 to 17.4

Fannie Mae also publishes a one-page illustration of the logic. Over 12 months the market rose 7%. A comparable whose contract captured 5% of that rise is adjusted up 2%; one that captured 8% is adjusted down 1%; one at 7% gets no adjustment.8 The adjustment is the market change the comparable’s price did not yet reflect.

Time-adjustment calculator

Move the market and watch each comparable’s adjustment

Effective date 05/01/2023. Each adjustment is price × rate × months from contract date, rounded to $1,000. At 1.0% the calculator gives $10,000, $32,000 and $17,000. The report shows $10,000, $30,000 and $15,000, about 0.9% to 1.0% a month, which its reconciliation describes as “approximately 1% per month.”

MH1 carries $0 on two comparables with contracts 112 and 116 days old; that can be right in a flat market, and the policy treats a zero adjustment as a conclusion that needs the same market support as any other. MH1’s third comparable, a short sale with a contract 544 days old, carries $5,000, about 1.4%.37

03 / Site and ViewFor every comparable

Location becomes Site Influence, and View gets a list for every comparable

The legacy Location row held a short coded entry. The URAR replaces it with Site Influence (Location), a multi-select list that always displays and can be adjusted for every comparable. View | Range always displays too, with a view type and a range of Full, Partial, Seasonal or Other.1 The subject’s impact rating for view and influence lives in the Site section, which the series covers in Part 2.

04 / Comparable WeightMost, Less, No Weight

Comparable Weight puts the appraiser’s reliance on each sale in a field

Comparable Weight (22.15.14) always displays and is required for every comparable. It has three answers. Most: the comparable was given more or most emphasis. Less: less emphasis than those weighted Most. No Weight: included but given no weight, for example a model match that was not a typical market transaction.1 Fannie Mae’s policy uses the same three words: the appraiser’s comments must “identify why the sale(s) were given the most weight, less weight, or no weight.”7

F-1 adds a guardrail. A property considered only to show a special feature, and never put in the grid, does not get No Weight. It goes in Additional Properties Analyzed Not Used, the subject of chapter 05.1

Field lift: SF1’s weights

Three comparables, three weights

SF1 grid Summary: adjusted prices $490,760, $490,540 and $534,400, Comparable Weight Most, Most and Less, indicated value $491,000, the reconciliation text explaining that Comp 3 was in a different subdivision, and five additional properties analyzed not used.

2$490,540Most
3$534,400Less

“Comps 1 and 2 were from the same neighborhood as the Subject. Comp 3 not given as much weight because of different subdivision.”

Reconciliation of Sales Comparison Approach (22.16.01)

SF1 is a consistent file: two Most, one Less, and a sentence that says why. The GSEs’ Lessons Learned job aid shows the failure the field exposes. Its example grid reports Most, Less and Less, and the reconciliation reads, in canned UAD 2.6 language, that the value “HAS BEEN WEIGHTED EQUALLY AMONG COMPARABLE SALES 1-3.”10

Lessons Learned example: a grid Summary with Comparable Weight Most, Less and Less circled, above a reconciliation sentence highlighted in yellow stating the value was weighted equally among comparable sales 1 to 3.

05 / Comps not usedAdditional Properties Analyzed Not Used

The properties the appraiser looked at and set aside now have a table

Additional Properties Analyzed Not Used has no legacy counterpart. Each row records an address, a sale date where there is one, a status, a Reason Not Used from an 18-answer list, and a required Comment. Land sales are excluded. The table displays when relevant, “initially, for the appraiser to provide additional context, or as part of any reconsideration process.”1

Rows from GSE sample SF1, v1.4, PDF p. 15;3 the 18 Reason Not Used answers from Appendix F-1 v1.4, p. 281.1

SF1’s reconciliation ties the table back to the grid: sales with five bedrooms, a media room and a wet bar were in the competitive market area, “exhibited in #4 and 5 of the Additional Properties Analyzed Not Used, but were not as comparable since they were larger, farther away, and superior quality.”3 A reviewer who wonders why those sales are missing can read the answer in the file.

The table matters for reconsideration of value as well. When a borrower or lender submits alternative sales, F-1 lets them appear here with the appraiser’s reason. Our reconsideration of value feature covers that process.

06 / Price per unit2 to 4 units, and the range rule

A four-unit grid reports price per unit, and the value must sit inside the adjusted range

The grid has no row that adjusts for a difference in unit count. Gross Building Finished Area, the combined area of all units, displays when the subject has more than one unit, and the Summary calculates Adjusted Price Per Unit (22.15.09): the comparable’s adjusted price divided by its units excluding ADUs.1 For small multifamily collateral that is a per-unit figure on every comparable, without recomputing it from area and bedroom counts.

Fannie Mae’s policy adds a check that the grid makes easy: “the indicated value in the Sales Comparison Approach must be within the range of the adjusted sales price of the comparables.”7 Both samples pass, and the figure shows by how much.

Sources: SF1 v1.4 p. 15; Scenario 2 v1.2 p. 17.34

Scenario 2 shows the pieces working together. Comparable 1 sold for the most, $850,000, and still ends lowest-but-one after a net adjustment of −$54,600. The appraiser placed Most weight on Comparable 3, “which best reflects the subject property,” and its per-unit figure sits between the other two. The indicated value, $785,000, is within $600 of Comparable 3’s adjusted price.4

07 / Risk lensRules, screens and limits

What a collateral team can test in this grid, and where the data stops

Each check below reads fields the grid now carries. None of them needs a reviewer to reconstruct the appraiser’s reasoning from an addendum first.

FOR EACH comparable:
  IF Comparable Weight (22.15.14) = "Most"
     AND Reconciliation of SCA (22.16.01) does not name it
  THEN flag "weight not explained"

  IF Listing Status IN ("Pending", "Settled Sale")
     AND days from Contract Date (22.01.30) to effective date > 90
     AND Contract Date adjustment = 0
     AND 22.16.01 names no technique (HPI, paired sales, model)
  THEN flag "zero time adjustment without support"

  IF Comparable Weight = "No Weight"
     AND the same address appears in Additional Properties
         Analyzed Not Used (22.17.02)
  THEN flag "listed twice"

FOR EACH additional property analyzed not used:
  IF Reason Not Used (22.17.05) = "Other (Describe)"
     AND Comment (22.17.06) is shorter than your minimum
  THEN flag "reason not explained"

IF Indicated Value (22.15.15) is outside the range of
   Adjusted Price (22.15.13) across the comparables
THEN flag "outside adjusted range"   (SB4-1.3-09)
Field IDs from Appendix F-1 v1.4, chapter 22.1 The range rule restates SB4-1.3-09.7 The thresholds are a lender’s choice; they are not GSE rules.

Where the data stops

  • Weight is self-reported. Comparable Weight comes from the same appraiser whose adjustments it describes. It exposes a contradiction between the weights and the commentary; it cannot show that the weighting was sound.
  • Reason codes can be thin. Other (Describe) and a technically accurate but uninformative reason both pass. The Comment field is where the explanation lives, and it is free text.
  • Contract dates come from the appraiser’s sources. F-1 allows Contract Date Unknown, and nothing in the report checks a date against an independent record.
  • Exact-looking numbers inherit their inputs. Adjusted Price Per Unit and a time adjustment are calculations on reported prices and dates, and carry any error in them.
  • Automated suggestions still need documentation. If a model proposes a time adjustment, SB4-1.3-09 still requires the report to describe the data sources, tools and technique. Collateral teams should keep any model output they use for review separate from requests to the appraiser about value.7

Six checks for the next sales grid you review

Sales grid review

0 of 6 checked

Saved in this browser only.

One gap remains open. The grid records the appraiser’s contract dates, weights and reasons in a form a machine can read, and nothing in UAD 3.6 checks those entries against an independent transaction record. A lender that wants that check has to build it, for example by matching contract and sale dates to MLS or public-record data it already licenses.

Research checked Oct. 17, 2026 against the GSE documents listed below.
