There is a pretty unique investment and development opportunity here.

1203 SW 144th St Burien, WA. 98166 currently has an upstairs 3 bed / 2 bath unit that is already rented for $3,300 per month with separate utilities. The layout of the property naturally supports a multi-unit setup because the lower level is a daylight walk out basement with separate access and substantial usable square footage.

There are currently two separate opportunities downstairs:

• The first is an approximately 760 sqft 1 bed / 1 bath unit that is already mostly functional. It would primarily require converting the existing downstairs laundry room into a kitchen to complete the unit. The plumbing, electrical and tile are done. Based on the size and layout, I believe this unit could realistically rent for around $2,200–$2,500+ per month. I have several interested parties at $2350 + utilities. 

• The second opportunity is converting the existing garage and workshop area into an additional 1 bed / 1 bath apartment of approximately 500–600 sqft. The ceilings are 8’+ and because it’s a daylight basement it does not feel like a typical basement conversion. I believe that unit could likely rent somewhere around $2200–$2500+ per month as well depending on the finishes.

One of the biggest advantages is the parking and lot layout. The property has RV parking along the side of the home, multiple driveway spaces, and additional shoulder parking directly in front of the property. Even after the conversions, the RV access would remain fully functional.

There is also strong potential for a future DADU in the rear portion of the property with access off 12th. My concept would be a modern 3-story unit with garage parking underneath and approximately 1,000 sqft of livable space above. Based on current Seattle-area construction pricing, I would estimate the DADU build cost somewhere around $275k–$400k depending on finishes, engineering, and permitting.

The reason I think the DADU concept is especially compelling is because Burien and the broader Seattle metro area are actively encouraging additional housing density and ADU/DADU development. I heard talks of an upcoming Square Footage allowance increase to 2000 sqft.

From everything I’ve researched, the lot configuration, parking, and access characteristics should make permitting very achievable.

What becomes really interesting is the long-term exit potential. 

If the property were eventually condo mapped or structured into a small HOA/condo association, there may be the ability to separately sell the units individually rather than only as one income property. In that scenario, the future DADU alone could potentially become a $650k–$850k+ standalone asset depending on market conditions and final design.

The upstairs residence and additional lower units could potentially support similar individual resale premiums because the property naturally lends itself to separation, privacy, and independent access.

Altogether, the property has the potential to generate roughly $7,700–$8,300+ per month immediately with the downstairs conversions alone, while also leaving substantial long-term upside through future DADU development and potential condoization/separate unit sales.
