Be sure to stay active now that you posted, setting up key word alerts can help with that.I can't help with the specifics of Tacoma, but I might suggest researching school quality, as that is a key factor in desirability.  

If you message me, I have a connection with a business in Chino Hills, CA who produces high quality cards for a low price!

My idea is to capitalize on the BRRR method to buy multiple homes without investing more money.Is it possible to buy a home in a decent market (either a foreclosure or short sale or something) that has an after repair value of $100,000 for $50,000 before repairs?

Apart from finding high cap rates and being okay with being in debt up to your eyeballs, are there any other methods of growing quickly?

Since there are so many different ways of real estate read up a little on each method once you find which one makes the most sense and peaks your interest then jump in and start taking action.

Correct me if im wrong or it isnt feasible to rely on the initial capital for future investments as much as I would hope it can.It seems the ideal situation/strategy is the BRRRR method where you can buy, rehab (to increase the value of the house), rent, refinance to get as much of your initial capital cash out in order to repeat the process.  

While there are some quality LO's there, I have also found some of them were working at Pizza Hut or Jiffy Lube last year (nothing against those places, just making a point). 

@John Suralik  subject too is a very old and easy method of acquiring RE its not big deal. what it is is uber risky for sellers unless the sellers have already lost their credit and don't care and are walking.. the reason is you take Title subject too  the existing loan.. remember loans stay in place unless paid off and even though all debt instruments have alienation clauses they are rarely envoked.

What is the best method to use for looking up pre-foreclosures and foreclosures?

I like both methods, but our travel nurses are a little more stable if your looking for a less turn over rate.
