Seattle investors build on small lots: a row of townhomes where a single house stood, a main house with detached accessory units, or a small middle-housing building that newer state rules now allow on more residential land.
In short: LendingStreet finances ground-up construction in Seattle for investors building 1 to 8 units, including townhomes, homes with ADUs, middle housing and small 5-8 unit buildings. Loans are sized on loan-to-cost, terms are set per project, and funds are released through inspected draws. Permitting time, slope rules and tree protections are the Seattle-specific items that shape the budget.
Seattle's high land prices push builders toward density. Townhome projects are common in Ballard, Fremont, Wallingford, Columbia City, West Seattle and the Central District, and many investors build a main home plus attached and detached accessory units to rent.
Washington's 2023 middle housing law requires cities the size of Seattle to allow more units on most residential lots, with more allowed near major transit. Seattle has been updating its zoning to match, so the number of units you can build on a lot may be higher than it was a few years ago.
Townhome projects that sell unit by unit usually depend on a unit lot subdivision or a similar legal setup so each home can close separately. That process has its own review, so start it alongside the building permit. Build-to-rent investors who plan to keep a main home and ADUs on one parcel skip that step, but they need rents strong enough to carry the full payment on the combined property after a DSCR refinance.
Common Seattle 1-8 unit project types: Each type has its own exit and its own local issues.
| Project type | Where it is common | Local note |
|---|---|---|
| Townhome row (3-4 units) | Ballard, Columbia City, West Seattle | Often sold as separate units |
| Main home plus ADUs | Neighborhood residential zones citywide | Rental exit; units on one parcel |
| Middle housing (4-6 units) | Near frequent transit | Confirm current zoning for the lot |
| Small 5-8 unit building | Lowrise zones | Larger permit scope and design review |
Permits run through the Seattle Department of Construction and Inspections. Review times vary by project type and workload, and some projects need design review. Lenders want plans approved, or close to approval, before construction funding starts.
Seattle's tree protection rules can limit where you build or require replacement trees, and environmentally critical areas, including steep slopes and landslide-prone areas, add geotechnical review. Find out early whether your lot has either.
Seattle's hills make many lots steep, which can add shoring, retaining walls and drainage. The long wet season affects excavation and framing schedules, and stormwater rules require on-site drainage solutions on many projects.
Washington's real estate excise tax is graduated by price and is customarily paid by the seller, but confirm how it applies to your land purchase and any later sale.
Three things drive the loan: the total project cost, the loan-to-cost percentage set for your project, and the finished value. Terms are set per project after we review plans, budget, permits and the builder.
Your equity covers the gap between the loan and total cost. On Seattle projects, soft costs and site work often run higher than investors expect, so a complete budget gives you a more accurate loan amount from the start.
This example is illustrative and not a quote. An investor builds four townhomes on a West Seattle lot and sells them on completion. Land costs $900,000, hard costs are $1,800,000, soft costs are $300,000 and the contingency is $120,000, for a total project cost of $3,120,000.
At a sample 80% loan-to-cost, the loan is $2,496,000 and the investor puts $624,000 into the project. Most of the loan funds through draws as work is completed.
If four townhomes at $975,000 each sells for $3,900,000 in total and selling costs run about 6%, or $234,000, net proceeds of $3,666,000 repay the $2,496,000 loan and leave $1,170,000 before interest and carrying costs, against $624,000 of cash invested.
| Item | Amount |
|---|---|
| Land | $900,000 |
| Hard construction costs | $1,800,000 |
| Soft costs (plans, engineering, permits, fees) | $300,000 |
| Contingency | $120,000 |
| Total project cost | $3,120,000 |
| Loan at a sample 80% LTC | $2,496,000 |
| Investor cash in the project | $624,000 |
| Sale price | $3,900,000 |
| Selling costs at about 6% | $234,000 |
| Left after repaying the loan, before interest and carry | $1,170,000 |
Funds are released through a draw schedule, not in one lump sum. You finish a stage of work, request a draw, an inspector confirms the work in place, and the funds for that stage are released.
Build the schedule around how your Seattle builder actually sequences the job. Our construction draw schedule calculator can help you map stages to dollars before you apply.
We look for investors with a buildable plan and the team to execute it. Experience can be your own or your general contractor's. Projects without plans or permits, or with no build track record and no experienced general contractor, usually do not qualify.
We also look at the land. Owning the lot, or having it under contract with a clear closing date, along with a survey and any soils work, makes the Seattle file faster to review and the budget easier to confirm.
Decide the exit before you close. A sale exit should be supported by recent new-build sales nearby. A rental exit should be supported by local rents that can carry a DSCR loan at the 1.0x standard minimum, with sub-1.0 programs available in some cases.
If the finished property needs more time, a short-term bridge loan can sometimes fill the gap before the sale or long-term refinance.
Our investor loans are business-purpose loans on non-owner-occupied property. For your Seattle project, share plans, budget and land details through the form below, or call (877) 298-1001.
On many residential lots, state middle housing rules and Seattle's zoning updates now allow more units than before. Confirm the current zoning for your parcel with the city or your architect before you price the land.
Not by themselves. Lots in environmentally critical areas need geotechnical work and engineering, and those costs belong in the budget. A well-engineered plan can qualify.
Many builders do, after the lot is subdivided or set up so each unit can be sold separately. Plan that legal structure early, since it affects the exit and the loan.
Yes. A main home with ADUs can refinance into a DSCR loan once leased. The rent from all the units goes into the ratio.
Through a draw schedule. Each stage of work is inspected before funds for that stage are released.
Yes. Once the property is leased, a DSCR loan can pay off the construction loan, qualifying on rent with 30-year terms available.
No. Our investor loans are business-purpose loans on non-owner-occupied property.
In most cases, yes, or approved plans with a clear path to permit. Projects without plans or permits usually do not qualify.
