@Rupesh Singh $600k could get you a solid 4plex in a Seattle suburb like Everett, Tacoma or Kent.

Without going over the top to pay for the house, I don't know how I could convince the other 2 siblings to agree to sell and move. Rent

we can place new tenants that we vet and move rents to market price.Disadvantage, Longer project time.

From an operations stand point, make sure the quote from the contractor includes — full containment and HEPA filtered negative air movers that ideally can exhaust to the exterior, manometer with print out logs documenting the containment’s negative pressure throughout the mitigation, full removal of affected materials (drywall, baseboard), (wood framing can sometimes be sanded and then sprayed with a spor/fungicide), and finally an *inspection by a third party environmental hygienist for air clearance*.

The Seattle and Tacoma forums are pretty quiet.The BP community so far looks great, and I love the positive attitude and cooperative spirit.  

I suggest you contact Anderson Advisors in Cheyenne, Las Vegas, or Tacoma. 

Granted our target was smaller than resi houses.. as the amount of viable timber ground was less but we were also working an area from the Oregon border to just south of Tacoma so about 100 miles by 400 miles  was our data base.. 

It's on the outskirts though in a pretty sizable neighborhood, near Tacoma, WA.

You are in a hot rental market as my son lives in Tacoma and pays $1,900 a month for a SFH that would run around $1,200 here in NC. 

I just recently purchasedI my first investment property in Tacoma, WA in Sept 2017 so I am a landlord as well !
