@Brian Burke I was pleased to see all three of my markets on your list. I'm in Seattle, Tacoma and Salem (driving right past Portland for all the reasons that @Jeremiah B. cites and you summerized).
@Troy Fisher hits the nail on the head about Seattle being difficult to work with. I have a contact that that's all they do is interface with the city for developers. THeir specialization in that relationship with the city has done very well for them. While I am not a lawyer or political operative harkening back to my highschool goverment class: Washington has a landlord tenant law that specifically prohibits rent control and superceeds anything that the city may try to do. That being said as the city goes so does the rest of the state eventually due to the population numbers and the one party system we have had here in washington for the last 30+ years.
One thing to keep in mind is that Seattle metro actually has a fairly small foot print given the size of the city and the surrounding areas offer opportunities. As in every major city these areas are very uneven in terms of quality, velocity of improvement and resultant opportunities.
@Caroline Weil @Alex Chin Make good points and Tacoma has been my area of focus for the last 3 or 4 years. One word of caution about tacoma, they have very restrictive regulations governing rental units, specifically that they must be registered with the city and that they can be inspected by the city at any time and the city can order repairs and updates. how this works in practice I dont know as I have stayed just outside of the city limits with my "farm" due to the restrictive nature of the ordinance. if enforecement is lax now there is nothing to stop later more strict enforcement to cause issues.
Havent heard much about Salem, OR. We just closed on our first property in Salem and you are right to place it in your fringe catagory. Salem has undergone steady growth for the last 15 or 20 years and I attribute much of that to the state government and resultant high paying jobs. Oregon is famous (notorious?) for being one of the only states to raise taxes in the depths of the recession. Nevermind that revenues went down as the millionaires left the state but it had the effect of cushioning the Salem market and setting up the city for growth after the recession. Salem is a sleepy market (While it does have a international airport it has no regular scheduled flights! none!). I'm not able to think of even one 100+ unit in the market. Thats a bit bigger than the fish I chase but gives you an idea. The city seems to me to be nearing the extent to which it can sprawl and I expect it to doubble back and start to infill and densify. Building seems to be where it is at in this market but scale may be difficult. I'm pursuing some land in this market to do just that.
I have functional peices of a team in all three markets and boots on the ground should you like to engage any of those peices I am willing to share and hungry for more work and opportunity myself.
Thanks for the post. I've learned from the other contributors and hope my information helps.
