An appraiser finds a rented comparable that sold for a cash-equivalent price of $648,000 with monthly gross rent of $2,700. The subject has monthly gross rent of $2,450, measured on the same basis. Sales in the market area indicate the same price-to-rent ratio applies, and no other adjustments are required. What is the indicated value of the subject, rounded to the nearest dollar?
Correct Answer
A) $588,000
648000 ÷ 2700 × 2450 = 588000. Common errors: using the comparable price without adjusting for income gives $648,000; inverting the income ratio gives $714,122; adding the income difference as dollars instead of applying the ratio gives $647,750.
Why This Is the Correct Answer
Option A is correct because the comparable's multiplier is $648,000 ÷ $2,700 = 240, and 240 × $2,450 = $588,000. The multiplier is applied to the same type and period of income from which it was derived.
Why the Other Options Are Wrong
Option B: $647,750
Option B, $647,750, comes from adding the dollar rent difference to the comparable price: $648,000 + ($2,450 − $2,700). The rent difference must be scaled by the multiplier, which gives 240 × $2,450 = $588,000.
Option C: $648,000
Option C, $648,000, simply repeats the comparable's price without adjusting for the subject's lower rent. Applying the 240 multiplier to $2,450 gives $588,000.
Option D: $714,122
Option D, $714,122, comes from inverting the income ratio: $648,000 ÷ $2,450 × $2,700. The subject earns less rent than the comparable, so its value should be lower, at $648,000 ÷ $2,700 × $2,450 = $588,000.
Price over rent, times rent
Divide the comparable's price by its rent to get the multiplier, then multiply by the subject's rent; lower subject rent means lower value.
How to use: Use this two-step check on any gross rent multiplier problem.
Exam Tip
Sanity-check direction: if the subject's rent is lower than the comparable's, the indicated value should be lower too.
Common Mistakes to Avoid
- -Inverting the rent ratio so value moves the wrong direction
- -Adding a rent difference in dollars to the price
- -Applying a monthly multiplier to annual rent
Concept Deep Dive
Analysis
This question tests applying a price-to-income ratio (a gross rent multiplier) from a comparable to the subject. Divide the comparable's price by its monthly rent to get the multiplier, then multiply that by the subject's monthly rent on the same basis.
Background Knowledge
A gross rent multiplier is the sale price divided by gross rent, and value is estimated by multiplying the subject's market rent by a multiplier derived from comparables. The multiplier must be applied to the same level and period of income from which it was derived.
Real-World Application
An appraiser valuing a rented single-family home divides each comparable rental's sale price by its monthly rent to derive a GRM, then applies the reconciled GRM to the subject's estimated monthly market rent.

Which model describes yield capitalization of property benefits?
An appraiser is valuing a duplex. A market survey of recent duplex sales reports prices at 10.8 times potential gross income, with stabilized vacancy and credit loss of 10% of PGI and no other income. The subject's rent schedule is unavailable, but the property manager's records show collected income of $54,000 a year, in line with market rent and the 10% market loss. What value is indicated?
The subject property is a fourplex with annual EGI of $72,000 and operating expenses of $28,800. Of those expenses, $18,000 is fixed and $10,800 varies in direct proportion to EGI. The owner's annual mortgage payments are $21,000. An appraiser projects that EGI will fall 10% because of higher vacancy. What is the projected NOI?
Annual NOI available for debt service is $168,000 and total annual mortgage principal and interest debt service is $120,000. What is NOI ÷ debt service?
Annual PGI is $250,000 and combined vacancy and collection loss is explicitly 12% of that same PGI base. There is no other income. What annual EGI remains?
Annual PGI is $360,000 and combined vacancy and collection loss is explicitly 8% of that same PGI base. There is no other income. What annual EGI remains?
Annual PGI is $640,000. Combined vacancy and collection loss is 6.25% of PGI. There is no other income. What EGI remains?
An appraiser is updating a prior appraisal of a triplex with potential gross income of $60,000 and no other income. The prior appraisal used vacancy and credit loss of 5% of PGI, and a new survey of competing rentals indicates 8%. The operating expenses of $24,000 are property taxes, insurance and contract services that do not vary with occupancy, and the market overall rate remains 7.5%. By what percentages do effective gross income and indicated value decrease?
Annual potential rental income is $600,000 and vacancy loss alone is $36,000. What percentage of potential rent does that loss represent?
In the subject's market, lenders on fourplexes have lowered their typical loan-to-value ratio from 70% to 60%. The annual mortgage constant remains 5% and the equity dividend rate remains 10%. The subject's NOI has not changed. How does this affect the overall rate indicated by the band of investment and the indicated value?
