Question 1

King County home prices often run above conforming loan limits. Does that rule out conventional financing?

Accepted Answer

Not across the board, but price point decides it city by city. Bellevue's mid-tier home value was $1,484,198 in June 2026 and Seattle's was $861,390, both of which push toward or past what a conforming conventional loan is sized for, which is exactly why portfolio and DSCR product carries so much of this market. The South King corridor prices differently: Federal Way $602,874, Auburn $614,442, Kent $654,483, Burien $649,914, Renton $756,961. A conventional file is more likely to fit cleanly there. We could not confirm the exact 2026 King County conforming loan limit, so send us the address and purchase price and we will tell you straight whether conventional or DSCR is the better fit. See conventional investment terms.

Question 2

How much does King County property tax vary by city, and why does that matter for my file?

Accepted Answer

More than most out-of-state buyers expect, and it changes your qualifying math city by city. The King County Assessor's 2026 collective levy rates run from Mercer Island's 0.65% up to Tukwila's 1.28%, with Seattle at 0.991% (about $8,536 a year on its $861,390 mid-tier value) and Bellevue at 0.743% (about $11,027 on $1,484,198). Because conventional underwriting counts the tax line in your debt-to-income ratio, the same purchase price qualifies differently depending on which city it sits in. See conventional investment terms and confirm the levy code for your specific parcel before you underwrite.

Question 3

My King County tax bill looks flat this year. Can I assume it stays that way after I close?

Accepted Answer

No, and treating it as flat is the most common underwriting mistake here. King County revalues every property annually rather than on sale, so a purchase does not reset your assessment the way it does in California or Florida, and the statewide 1% cap that people cite is a limit on a taxing district's total LEVY, not a cap on your individual bill. It shows up in the data: King County's total levy rose from $7.7 billion in 2025 to $8.4 billion in 2026, about 10%, while total assessed value rose only 5.4%, driven by voter-approved measures rather than value growth. Underwrite the escrow line to move, not to hold flat. See conventional investment terms and talk to your CPA about your specific parcel.

Question 4

Does Washington's new rent cap change how I should underwrite a King County rental?

Accepted Answer

Yes, and Washington now has a real statewide rent cap, not the no-rent-control state some buyers still expect. RCW 59.18.700 bars any rent increase in the first 12 months of a tenancy and caps increases after that at 7% plus CPI or 10%, whichever is less; the published maximum is 9.683% for calendar 2026. There is no cap on what you charge a new tenant once a unit turns over, and new construction is exempt for 12 years from its first certificate of occupancy. Underwrite the rent trajectory on that basis rather than assuming unlimited annual increases. See conventional investment terms and talk to your attorney about the notice rules in the specific city you are buying in.

Question 5

Should I finance a King County rental as conventional or as DSCR?

Accepted Answer

If your documented income clears the file, conventional is usually the lower-cost structure, but the yield story tells you where it works best. Gross rental yields run 3.08% in Seattle and just 2.24% in Bellevue against 3.44% to 3.81% across Renton, Kent, Auburn and Federal Way, so a Seattle or Bellevue hold is more of an appreciation thesis than a cash-flow one, while the South King corridor is where a rent-qualified DSCR loan pencils most easily. A conventional file works anywhere your tax returns support it. See conventional investment terms and we will run both structures side by side against your numbers.

Question 6

Does King County's geology add real underwriting cost to a conventional purchase, or is that overstated?

Accepted Answer

It is real, and it is a diligence item rather than a formality. The Seattle Fault Zone and the Cascadia Subduction Zone are the region's dominant hazards, liquefaction risk concentrates in fill and soft-sediment areas such as Harbor Island, SODO, the Duwamish Valley, Interbay and Rainier Valley, and King County separately maps and regulates landslide hazard areas along bluffs and river corridors. Earthquake coverage is excluded from a standard homeowner policy and has to be added or bought separately, with deductibles commonly 10% to 25% of the covered amount. Steep-slope and liquefaction-zone parcels can trigger geotechnical report requirements that change your carrying cost. Budget for a bound insurance quote and, where the parcel warrants it, a geotechnical review before you close. See conventional investment terms.

Question 7

What credit score do I need for a conventional investment loan in Seattle?

Accepted Answer

Credit starts at 580 on this program. That is the lowest entry point of anything we write, but the trade is real: conventional is fully documented, so tax returns, income, and your debt-to-income ratio all count. In King County that ratio is where files break, because the property tax line varies by city, from about 0.65% of value on Mercer Island to 1.28% in Tukwila. The same purchase price can qualify in one city and not the next. Subject to underwriting.

Question 8

How much do I need to put down on a Seattle conventional investment purchase?

Accepted Answer

At least 20%. Max leverage is up to 80% LTV on non-owner-occupied property, so on a $600,000 Federal Way purchase, near that city's $602,874 mid-tier value, that is up to $480,000 from us and $120,000 from you (600,000 x 80% = 480,000), before closing costs. The same 20% on Bellevue's $1,484,198 mid-tier value is a very different cash requirement, which is part of why the South King corridor is where conventional fits most cleanly here. Subject to underwriting.
