Florida comparable sales adjustment calculator, 2026 appraisal math.
Practice sales comparison adjustments for superior and inferior comparable features. Built for Florida exam direction traps, not for professional appraisal reports.
In Florida real estate exam comparable sales problems, adjust the comparable, not the subject. Add when the comparable is inferior. Subtract when the comparable is superior. Then use adjusted comparable prices to estimate the subject property's indicated value.
The subject property is the benchmark. Change the comparable sale price to make it more like the subject.
If the comparable is worse than the subject, add the feature value to the comparable sale price.
If the comparable is better than the subject, subtract the feature value from the comparable sale price.
If the comparable already matches the subject for that item, leave that feature alone.
Combine positive and negative adjustments before adding the net amount to the sale price.
Use adjusted comparable prices to estimate the subject value. Do not rely on raw sale prices.
Real Estate Appraisal includes USPAP, market value, sales comparison, cost-depreciation, income capitalization, CMA, and BPO.
DBPR lists the sales associate exam as a closed-book, multiple-choice exam with 19 content areas.
Comparable adjustment math should be a fast direction check so you can save time for law and contract questions.
This tool teaches exam arithmetic. It is not a professional appraisal, CMA, BPO, or valuation report.
Five steps before you touch the answer choices.
Comparable sales questions are usually direction tests. Decide the adjustment target and direction before doing the arithmetic.
Identify the subject
Keep the subject property fixed. Every adjustment is made to the comparable sale price, not to the subject.
List each difference
Separate location, size, condition, market conditions, and feature differences before doing the math.
Choose inferior or superior
Ask whether the comparable is worse or better than the subject for that feature. Inferior means add. Superior means subtract.
Apply signed adjustments
Net the plus and minus adjustments, then add the net amount to the comparable sale price.
Reconcile from adjusted comps
Use the adjusted prices to estimate the subject value. Follow the question if it asks for one comp, an average, or a reconciled conclusion.
Adjust the comparable sale price toward the subject.
Always adjust the comparable, not the subject. If the comparable is inferior, add. If it is superior, subtract.
The adjustment is the value difference for that feature, not the cost to install it unless the question says so.
A simple average is a classroom shortcut. Real appraisal work may weight the best comparable more heavily.
The exam may describe the subject as better or worse, but your math still adjusts the comparable sale price. Keep asking: what would this comparable have sold for if it were more like the subject?

Name the final ask before you calculate.
The same fact pattern can ask for an adjusted comparable sale price, a net adjustment, or the subject's indicated value.
Is the question asking for adjusted sale price or subject value?
Adjusted sale price uses one comp. Subject value usually asks you to compare or reconcile multiple adjusted comps.
Does the comparable lack something the subject has?
The comparable is inferior for that feature. Add the feature value to the comparable sale price.
Does the comparable have something the subject lacks?
The comparable is superior for that feature. Subtract the feature value from the comparable sale price.
Does the problem give cost or value?
Use the adjustment amount the stem gives. A feature's cost and market value are not always the same unless the question says to treat them that way.
Four comparable adjustment patterns to know cold.
These examples focus on the sales comparison direction rules most likely to create wrong answer choices.
Comparable sold for $415,000 but lacks a $12,000 feature the subject has
Add because the comparable is inferior.
Comparable sold for $415,000 and has an $8,000 feature the subject lacks
Subtract because the comparable is superior.
Comparable sold for $390,000, is $10,000 inferior for garage, and is $6,000 superior for lot size
Net the adjustments before applying them to the sale price.
Adjusted comps are $412,000, $416,000, and $418,000
Do not average unadjusted sale prices.
Five comparable sales questions to solve first.
These original exam-style questions test add, subtract, net adjustment, indicated value, and no-adjustment traps without using copied exam items.
A comparable sold for $415,000 and lacks a $12,000 feature the subject has. What is the adjusted comparable price?
The comparable is inferior because it lacks the feature. Add $12,000 to $415,000.
A comparable sold for $415,000 and has an $8,000 pool the subject does not have. What is the adjusted comparable price?
The comparable is superior for that feature. Subtract $8,000 from the comparable sale price.
A comparable sold for $390,000. It is $10,000 inferior for garage space and $6,000 superior for lot size. What is the adjusted sale price?
Add $10,000 and subtract $6,000 for a net positive adjustment of $4,000. $390,000 plus $4,000 equals $394,000.
Three adjusted comparable prices are $412,000, $416,000, and $418,000. Which number set should guide subject value?
The sales comparison approach uses adjusted comparable prices. Raw prices have not been made comparable to the subject.
The subject and comparable have the same condition rating. What adjustment should be made for condition?
If the feature already matches the subject, no condition adjustment is needed.
Comparable sales mistakes that turn easy math sideways.
The arithmetic is usually simple. The hard part is keeping the target, direction, and final answer type straight.
Adjusting the subject property
The exam wants you to adjust the comparable sale price. The subject is the standard you are adjusting toward.
Reversing add and subtract
If the comparable lacks something the subject has, add to the comparable. If the comparable has something extra, subtract from the comparable.
Using raw sale prices
Raw comp prices can be misleading. The point of the sales comparison approach is to compare adjusted prices.
Treating every average as an appraisal
A simple average is a classroom shortcut. Professional appraisal reconciliation can weight the best-supported comparable more heavily.
Confusing CMA, BPO, and appraisal
Florida sales associate exam content includes appraisal concepts, CMA, and BPO. A licensee study calculation is not the same as issuing an appraisal report.

How this calculator page was built and checked.
Florida exam scope was checked against the current DBPR Sales Associate Candidate Information Booklet and DBPR Examination Information page.
The DBPR booklet lists Real Estate Appraisal at 8 percent and names the sales comparison approach, cost-depreciation approach, income capitalization approach, CMA, and BPO.
Florida appraisal-definition context was checked against currently published 2025 Florida Statutes section 475.611.
USPAP context was checked against The Appraisal Foundation as professional appraisal background, not as a source for this study calculator's arithmetic.
Practice questions and worked examples are original instructional examples, not copied exam questions.
The calculator uses simple averaging as an exam-practice shortcut when multiple adjusted comps are entered. Real appraisal reconciliation may require different weighting and documentation.
Frequently asked questions.
Do you adjust the subject or the comparable?+
Adjust the comparable. The subject property is the benchmark. You change the comparable sale price to show what it would have sold for if it were more like the subject.
When do you add to a comparable sale price?+
Add when the comparable is inferior to the subject. For example, if the subject has a garage and the comparable does not, add the garage value to the comparable sale price.
When do you subtract from a comparable sale price?+
Subtract when the comparable is superior to the subject. For example, if the comparable has a pool and the subject does not, subtract the pool value from the comparable sale price.
What is a net adjustment in comparable sales math?+
A net adjustment is the total of all positive and negative adjustments for a comparable. If you add $10,000 and subtract $6,000, the net adjustment is plus $4,000.
How do adjusted comps estimate subject value?+
After each comparable is adjusted toward the subject, the adjusted sale prices form a value range. The exam may ask for a single adjusted comp, a simple average, or a reconciled value based on the adjusted range.
Is a CMA the same as an appraisal in Florida?+
No. DBPR exam content includes both appraisal concepts and comparative market analysis. This calculator teaches exam math and does not create an appraisal report, CMA, BPO, or professional valuation opinion.
Is this calculator a real appraisal tool?+
No. It is a Florida real estate exam study calculator. Real appraisal work requires professional standards, market support, competency, scope-of-work decisions, and appraiser judgment.
