What would each path cost?
Start with two homes that meet the same needs. A countywide home value and rent index can represent different sizes and property types.
Adjust tax and growth assumptions
Mortgage, growth and property tax rates are illustrative scenario assumptions. Check your lender quote and the property's actual tax bill.
Starting scenario · 10 years · Before income taxes
Renting and investing finishes $382,420 ahead
This compares projected home equity after selling costs with invested cash. It assumes the cheaper housing path invests the entire monthly difference. Changing that behavior can change the answer.
Buying cash at closing
$140,463
Down payment + 3% closing costs; reserves extra

What matters for your decision in Bellingham?
Check the rental’s registration and safety-inspection record
Bellingham’s rental program requires registration, annual license renewal and safety inspections, with specific exemptions. The city’s current guidance describes an inspection before renting and repeat inspections about every three to three-and-a-half years. Its public dashboard shows registered properties and inspection results; the city invites address-specific questions when a property cannot be found. Registration status and the condition of the unit are separate checks.
Bellingham rental registration, inspection cycle and public results · Undated current Rental Registration and Safety Inspection Program guidance citing BMC 6.15. Checked .
Look up the exact rental address and unit, ask for the latest inspection result and confirm that listed corrections were completed. Compare the unit’s present condition and lease costs with the home you would buy. If your ownership plan depends on renting part of the property, confirm the applicable registration, inspection and exemption rules before counting income, and model that separately in the house-hack tool. Do not infer safety or a legal exemption merely because a search returns no record.
Compare actual homes with the same financing assumptions in Everett or Lakewood. Their local requirements and property costs may differ.
Condo dues and upcoming work
For a condo, enter the actual HOA dues and review the reserve study, meeting minutes and special assessments. The starting scenario uses $0 dues; that can understate a condo's cost.
The property's tax bill
The 0.98% starting tax rate is an illustrative assumption, not a verified rate for this home. Use the annual tax bill ÷ purchase price × 100 to enter a matching rate. Check the address's county through the county assessor and treasurer directory. Review how the bill could change after purchase.
Comparable space and location
Compare similar bedroom counts, commute needs, parking and outdoor space. A county home index and a county rent index do not describe a matched pair of homes.
A shorter stay and cash reserves
Try a three-year exit alongside your expected stay. Include moving costs, repairs and an emergency reserve in your real budget; the cash-at-closing figure does not include those reserves.
If you would rent out a room or unit, model a house hack separately so rental income and vacancy are explicit.

- How to use these indices
- Zillow's data definitions describe typical home values (ZHVI) and typical market rents (ZORI). They cover their respective housing stocks, not a matched pair of homes, Bellingham city medians or an individual property quote. ZIP-level and listing-based sources use different coverage and may differ. Published source files may be revised after retrieval.
- Financing and ownership costs
- 30-year conventional loan; 3% purchase closing costs; $1,800 yearly home insurance, growing 3%; maintenance at 1.5% of purchase price, growing 2.5%; property taxes growing 2%; $200 monthly owner utilities. PMI is modeled below 20% down at a 0.5% annual rate, until the modeled loan-to-value reaches 80%. All are illustrative assumptions.
- Renting and investing
- $200 yearly renter insurance and $150 monthly utilities. Renting starts with the buyer's down payment and closing costs invested. The path with lower ongoing housing costs invests the difference. Security deposits, broker fees and moving costs are excluded from this comparison.
- Selling and tax treatment
- Selling costs total 7.5% of future home value, including commissions, closing costs and sale preparation. Buyer wealth is equity after selling costs plus invested savings; renter wealth is the investment balance. This comparison excludes income-tax deductions and taxes on investment gains. Dollars are not inflation-adjusted.

Bellingham rent vs buy questions
Does a lower monthly rent mean renting is better?
It helps your cash budget, but the wealth result also depends on what you invest, home value growth and when you move. Check both the monthly comparison and the exit-year table.
Why is there no universal Bellingham break-even year?
The answer changes with price, rent, financing and investment returns. “Not within 30 years” describes the modeled window, not a claim that buying can never catch up. A first crossover also does not guarantee buying stays ahead.
Can I compare a cash purchase?
Yes. Set the down payment to 100%. The rent scenario then invests the purchase cash and closing costs, so the opportunity cost of paying cash remains in the comparison.
