Cost of Adding On
In West Michigan, home additions typically cost $150–$350 per square foot depending on complexity. A 400 sq ft family room addition runs $60,000–$140,000. A second-story addition over an existing footprint costs $100,000–$250,000+.
You keep your current mortgage rate, neighborhood, and school district. There are no realtor commissions, no moving costs, and no bidding wars.
Cost of Selling and Buying
Selling your current home involves 5–6% realtor commissions, plus closing costs on both the sale and purchase. On a $350,000 home, that is roughly $25,000–$35,000 in transaction costs alone — before moving expenses, temporary housing, or the price premium on a larger home.
In the current West Michigan market, mortgage rates are significantly higher than what many homeowners locked in during 2020–2021. Moving means losing that rate.
When Adding On Makes Sense
- You love your neighborhood and school district
- Your lot has room to expand
- Your foundation and structure are sound
- You have a low-rate mortgage you do not want to lose
When Moving Makes Sense
- Your lot cannot accommodate the space you need
- The home has fundamental issues (layout, location, condition)
- You are relocating for work
- The cost of additions exceeds the value they would add
