Top Methods to Calculate Property Value Accurately

1. Comparative Market Analysis (CMA)

What it is: A method used by real estate agents to compare similar recently sold properties in the same area.

How to do it:

Choose at least 35 similar properties (same size, type, and location).
Look at the sale prices and date of sale.
Adjust for differences (like amenities or renovation work).

Example:
If a similar house with an extra bedroom sold for ?60 lakhs, and bedrooms typically add ?3 lakhs in value in your area, adjust your base propertys value accordingly.

2.Income Capitalization Approach (For Rental Properties)

What it is: Ideal for investment properties, it uses rental income to estimate value.

Formula:
Property Value = Net Operating Income (NOI) Capitalization Rate (Cap Rate)

Steps:

Calculate NOI: Subtract annual expenses from annual rental income.
Find average Cap Rate in the locality (usually 4%10%).

Example:
If a property generates ?6,00,000 annually with ?1,00,000 in expenses, NOI = ?5,00,000.
If Cap Rate = 6%, then:
Property Value = ?5,00,000 0.06 = ?83,33,333

3.Cost Approach

What it is: Estimates value based on the cost to rebuild the property from scratch minus depreciation, plus land value.

Formula:
Property Value = (Cost of Rebuilding Depreciation) + Land Value

Best used for: Newer properties or special-use buildings like schools or factories.
