Even 300 is on the lower end compared to the big players so in addition to mailers i am making cold calls and networking anyway possible during the day.

Most of this growth is being channeled into the western urban county.There's enabling land use legislation in the works: As of today, Snohomish county is nearing the end process of lowering the lot size minimums for Duplexes to the same size as SFR, instead of 150%, so conversions should be relatively simple to permit. 

These large players that use wholesalers with assignable contracts should be careful.

Who are the major players? 

Here out west, I've never heard of anybody doing a closing with an attorney in my 8 years in real estate and doing business with big players in CO and AZ.

Accelerating the payment of some taxes is well worth it to enable you to get financing.Be sure to aggressively appeal your property tax assessments downward, if at all possible, and shop aggressively for the best insurance rates (and terms, such as looking for "actual cost" coverage with high deductibles), as many insurers have increased rates sharply in the last year.

This will enable you to buy more doors faster.

It seems this state has one or two big players in each market then several small potatoes like me.

If a broker is willing to do it, they usually can if they are tied in with major national players in mortgage banking.

There are lots of options out there but you're going to have to put in the effort and every city/county/state will have different players.
