Home Addition vs. Moving: The Complete Financial Analysis

The Big Decision

When you need more space, you have two main options: add on to your current home or move to a larger one. Both have significant financial implications.

Cost of Moving

• Real estate commissions (typically 5-6% of sale price)
• Closing costs on both sale and purchase (2-5% each)
• Moving expenses ($2,000-$10,000+)
• New furniture and adjustments
• Potential higher property taxes
• Time and stress of the process

Cost of Adding On

• Construction costs ($200-$500+ per square foot in California)
• Permits and fees (typically 1-3% of project cost)
• Temporary displacement during construction
• Potential property tax increase (only on new square footage)
• Increased home value (typically 50-80% ROI)

When to Add On

An addition makes sense when:

• You love your neighborhood and schools
• Your lot can accommodate the addition
• The addition won't over-improve for your area
• The cost is less than the value it adds plus moving costs
