8.4 Transactional Adjustments and Adjustment Sequence

The One Rule You Must Not Break

In the sales comparison approach, always adjust the comparable to the subject. Each line on the grid changes the comparable’s price to estimate what that comparable would have sold for if it had been more like the subject (same rights, cash-equivalent terms, normal conditions, subject’s effective date, subject’s location/physical features, and so on).

Wrong: Changing the subject’s features in your head to match Comp 2.
Right: Leaving the subject fixed and restating Comp 2’s price.

If you reverse signs under stress, every indication will be wrong even when your dollar amounts are “reasonable.”

Why Sequence Exists

Not all adjustments are equal in kind. Transactional adjustments remove deal-specific distortions so the price reflects a normal transfer of the relevant real property rights on a cash-equivalent basis as of a common date. Property adjustments then explain real estate differences.

A widely taught sequence is:

1. Real property rights conveyed
2. Financing terms (cash equivalency)
3. Conditions of sale
4. Expenditures immediately after purchase
5. Market conditions (time)
6. Then location
7. Then other physical / economic / use / non-realty property adjustments (order among property items can vary by form and problem, but transactional block comes first)

Why this order on the exam: You should not apply a careful garage adjustment to a related-party, nonmarket-financed sale from three years ago without first bringing rights, financing, conditions, immediate expenditures, and time into line. Transactional cleanup first; property fine-tuning second.

Quantitative techniques (paired data, cost, income, regression) that measure adjustments are ECO IV.d and are expanded in Chapter 9. This section focuses on direction, sequence, % vs $, and a complete grid walkthrough.

Percentage vs Dollar Adjustments

Applying Percentages in Sequence

A common approach applies sequential percentage adjustments to a running adjusted price (compounded sequence), or applies independent percentages to the original price when the method says so—follow a consistent method and the problem’s instructions.

Illustrative sequential method (transactional):

Start with sale price $P_0$.

1. Rights: $P_1 = P_0 × (1 + r_{rights})$ (or $P_0 + $ amount)
2. Financing: $P_2 = P_1 × (1 + r_{fin})$
3. Conditions: $P_3 = P_2 × (1 + r_{cond})$
4. Expenditures: $P_4 = P_3 + E$ (usually a dollar add for required spend)
5. Market conditions: $P_5 = P_4 × (1 + r_{time})$
6. Property adjustments: add/subtract dollar amounts (or further %) for location, GLA, garage, etc.

Dollar property adjustments are often applied after the transactional chain produces a time-adjusted cash-equivalent price.

Exam tip: If a stem gives “adjust +10% for market conditions and −$5,000 for a superior garage,” compute the time-adjusted price first, then apply the garage dollar amount to that adjusted figure unless the stem specifies otherwise.

Sign Convention Drill

Subject: 2-car garage. Comp: 1-car garage (inferior). Adjustment to comp: +$8,000 (example).

Subject: No pool. Comp: Has pool buyers pay for (superior). Adjustment to comp: −$12,000.

Subject: Effective date today. Comp: Sold 1 year ago; prices up 4%. Adjustment to comp: +4% (comp inferior as to time in a rising market—its historical price is too low for today).

Subject: Fee simple. Comp: Sold with adverse easement reducing utility (inferior rights). Adjustment to comp: upward if the easement hurt price, to restate toward unencumbered fee—or reject if unmeasurable.

Assignment Facts

• Subject: Fee simple single-family residence; effective date August 1, 2026; 1,800 sq ft GLA; 3 bed / 2 bath; 2-car garage; average condition; no pool; typical residential lot in Meadowbrook subdivision.
• Market evidence (assumed supported for the example):
  • Market conditions: prices have been rising about 0.5% per month recently
  • Extra full bath contributes $10,000
  • Second garage stall contributes $8,000
  • In-ground pool contributes $15,000
  • GLA differences: $60 per sq ft of GLA difference (contribution rate from paired data—not cost new)

Comparable Sale Facts

Months from sale date to Aug 1, 2026 (simplified):

• Comp A: 3 months → +1.5% time
• Comp B: 1 month → +0.5% time
• Comp C: 6 months → +3.0% time

Step-Through: Comp A

1. Rights: equal → $420,000
2. Financing: market → $420,000
3. Conditions: arm’s-length → $420,000
4. Expenditures: none → $420,000
5. Market conditions: $420,000 × 1.015 = $426,300
6. Property adjustments (to subject):
   • GLA: Comp 1,750 vs subject 1,800 → comp smaller (inferior) → +(50 × $60) = +$3,000
   • Baths: equal → $0
   • Garage: equal → $0
   • Pool: equal → $0
   • Location: equal → $0

Adjusted indication A: $426,300 + $3,000 = $429,300

Step-Through: Comp B

1. Rights: equal → $455,000
2. Financing: replace contract price with cash-equivalent $445,000 (financing adjustment of −$10,000 already embedded by using CE price)
3. Conditions: arm’s-length → $445,000
4. Expenditures: none → $445,000
5. Market conditions: $445,000 × 1.005 = $447,225
6. Property:
   • GLA: Comp 1,900 vs 1,800 → comp larger (superior) → −(100 × $60) = −$6,000
   • Baths: Comp 3 vs subject 2 → comp superior → −$10,000
   • Garage: equal → $0
   • Pool: equal → $0

Adjusted indication B: $447,225 − $6,000 − $10,000 = $431,225

Step-Through: Comp C

1. Rights: equal → $400,000
2. Financing: market → $400,000
3. Conditions of sale: short sale → $400,000 × 1.03 = $412,000
4. Expenditures immediately after sale: +$5,000 → $417,000
5. Market conditions: $417,000 × 1.03 = $429,510
6. Property:
   • GLA: equal → $0
   • Baths: equal → $0
   • Garage: Comp 1-car vs subject 2-car → comp inferior → +$8,000
   • Pool: Comp has pool, subject does not → comp superior → −$15,000

Adjusted indication C: $429,510 + $8,000 − $15,000 = $422,510

Grid Summary

Reconciliation Sketch

Adjusted prices cluster about $423,000–$431,000. An appraiser might reconcile near $428,000–$430,000, weighting A and B more if Comp C required larger conditions and feature netting. Exact final opinion belongs to reconciliation judgment (ECO IV.f / Chapter 9), but the process is what the exam grades in sequence items: transactional cleanup first, correct signs, adjust comps to subject.

Net vs Gross Adjustment Logic (Exam Awareness)

After the grid:

• Net adjustment = algebraic sum of adjustments (ups minus downs) relative to sale price
• Gross adjustment = sum of absolute values of adjustments

Large gross adjustments can signal a weak comparable even if net is small (offsetting pluses and minuses). That does not automatically invalidate a sale, but it is a quality flag in reconciliation—prefer comps needing less total correction when they are true substitutes.

Common Sequence and Math Traps

1. Adjusting the subject instead of the comparable (sign errors everywhere).
2. Property adjustments before fixing financing/conditions/time.
3. Wrong sign: treating superior comp features as positive adjustments.
4. Percent of the wrong base (applying time % to a price that already had inconsistent math).
5. Using cost new as the automatic adjustment for a feature (contribution may be less).
6. Ignoring cash equivalency when concessions clearly inflated price.
7. Forcing a distressed sale through a huge unsupported conditions percentage instead of rejecting it.
8. Double-counting GLA with both unit-rate analysis and a full size line without a coherent method.

Chapter 8 Integration for Area IV

Chapter 9 continues with how to measure adjustments (paired data, cost, income, regression), qualitative techniques, and reconciliation to a single SCA indication. If selection, units, elements, and sequence are weak, measurement techniques cannot save the approach. For Licensed Residential candidates especially—where Sales Comparison is about one-quarter of scored items—this fundamentals chapter is the highest-yield valuation skill set on the National Exam.
