PRICE VS. TERMS OF SALE

• Seller Financing Better or worse than Standard?

• Assumed Financing Better terms?

• Seller-Paid Points Generally, Buyer pays points. In a Buyer’s market, Seller may pay points

COMPARING & ADJUSTING SALES

• Identify and Compare Sales Characteristics

• Make Market-Derived Adjustments that are: Reasonable Are consistent among the sales Explain the price differences between the

sales & subject

USING MATCHED PAIRS

Adjusting Sales with the Direct Market Method

Finding Adjustments for Size Subject: 2,600 SF living area

Sales: Similar, except different in size

Adjustment: Search for sales differing only in size

16

USING MATCHED PAIRS Evidence

o 2,500 SFo 2,700 SF

Calculation:o Sale Size Priceo B= 2,700 SF $280Ko A= 2,500 SF $270Ko Difference 200 SF $10 K

Adjustment for Size:

$10,000÷200 SF

= $50 SF Change

17

ESTIMATING ADJUSTMENTS BY DEPRECIATED COST

Difference Subject has 440 SF garage

Comparable sale has no garage

Unit cost new is estimated at $33.50/SF

Cost New of Garage Size 440 SF @ $33.50 per SF

Total replacement costo 440 SF X $33.50 per SF = $14,470

18

ESTIMATING ADJUSTMENTS BY DEPRECIATED COST

Depreciation Age of subject garage = 29 yrs

Economic life = 100 yrs

% depreciation = 29/100 = 29%

Amount of depreciation is 29% of $14,470 or $4,275

Adjustment Amount Cost new $14,470

Less: Depreciation - $4,275

Equals: Amt. of adjust rounded $10,000

AUTOMATED VALUATION MODELS

• Computer Software Program Analyzes data in specified area or

neighborhood Relates results of database search to

subject property information imputed into the model.

• When Applied to an Individual Property It Is Not an Appraisal.

• An AVM May Become the Basis for an Appraisal

SUMMARY

25

Analyzing and adjusting comparable sales rely on two main methods: the direct comparison method and the elements of comparison method.

The direct comparison method simply compares the overall desirability of each sold property with that of the subject, without any adjustments. The elements of comparison method compares the sales with reference to the details of four critical elements: the terms and conditions of sale, the time of sale, the location elements, and the physical elements of the properties.
