Washington: evidence to offer worksheet
Free property worksheet. Entries remain in this browser page and are not submitted or saved. Print or save your completed worksheet before closing. The worked example is hypothetical, not a property quote or market forecast.
1. Match the evidence
Seattle’s published average moved down 10 basis points from both Q2 2026 and Q3 2025. Eastern Washington’s rounded regional series moved from 6.5% to 6.2% quarterly, while remaining above its prior-year quarter. The eastern report calculates changes from greater precision, so its printed basis-point labels can differ from rounded arithmetic. Do not infer a Spokane premium solely from these different cohorts. Thin local sales and the unresolved Tri-Cities column are reasons to inspect actual closing income.
2. Complete the local document checks
Seattle: modest compression does not settle the lease-up question
Map actual competitor openings, concessions and lease expirations. Confirm Seattle notice and compliance obligations, and model the cash delay before any lawful, achievable increase.
Bellevue, Issaquah and Redmond: match the commute and the competing product
Build a short list of direct competitors and document their opening dates and incentives. Check the applicable city’s notice rules rather than assuming Seattle’s local ordinance governs every Eastside address.
Spokane County: a local sale series with a small cap denominator
Request closing price and consistent NOI for similar local sales. Quote replacement coverage and income restoration, and test lower collections with a wider exit rather than relying on the county point alone.
Yakima, Wenatchee Valley and Tri-Cities: keep thin evidence and source errors visible
Verify sale dates, income definitions and unit counts for local comps. Obtain a current insurance quote and collection history; leave the terminal cap subject to evidence rather than filling the missing cell.
Tacoma, Everett, Vancouver and smaller markets: local transactions are not local cap rates
Obtain local tax estimates, current lease documents, ordinance guidance and comparable NOI. Allow for marketing time and lender restrictions if the likely exit buyer pool is small.
3. Reconcile the buyer budget
| Item | Example |
|---|---|
| Purchase price | $4,800,000 |
| Scheduled annual rent | $504,000 |
| Other recurring income | $8,000 |
| Collection / concession / vacancy loss | -$40,000 |
| Effective income | $472,000 |
| taxes | $55,000 |
| insurance | $24,000 |
| utilities | $24,000 |
| maintenance | $36,000 |
| management | $32,000 |
| administration | $13,000 |
| Recurring expense total | $184,000 |
| NOI before debt and reserve | $288,000 |
| Annual debt service | $218,443 |
| Annual replacement reserve | $16,000 |
| Cash after debt and reserve | $53,557 |
| Down payment + closing + initial work | $2,176,000 |
Loan $2,880,000 at an assumed 6.5% for 30 years, monthly amortization. Going-in cap 6.00%; DSCR 1.32× before reserve, 1.25× after reserve; cash-on-cash 2.46%. Cash basis excludes an initial reserve deposit; add any lender-required deposit. No loan quote is implied.
4. Test the exit and invalidate the thesis
Value = annual NOI ÷ (cap percent ÷ 100). Keep cumulative NOI change separate from annual rent growth. A simple value comparison excludes debt payoff, sale costs, income tax and interim cash flows.
Map the lawful collection path
Read leases, prior increases, exemptions and local notice rules. Schedule when achievable rent can actually become cash.
Match the property to the evidence
Separate Seattle market averages from eastern county sales. Check cap count, vintage, condition and income date before using a comparable.
Fund the gap before relying on an exit
Include buyer taxes, insurance, initial work and lease-up cash. Test a wider yield and lower income independently of a policy-rate forecast.
