How should I think about the resale value gained from the square footage being finished?

Quote from @Mike McMurray:But, in Washington which is in answer to your question: RCW 61.12.200 comes into play.

I own a beautiful piece of land in Carson, WA with much potential for short term rentals.

The home is 1,841 square feet and was constructed in 2009.The use of the accelerated depreciation strategy helps real estate investors to reduce the tax liability immediately which therefore increases their bottom line due to the offsetting of income.

Many of us have our own personal set of attributes we look at, such as price per square foot.  

I bought my first investment property in WA (where I live) and my second in NC (not where I live).

who might know where I could find a wholesale contract for the state of wa 

Get your financing squared away as well. 

And for sure sellers should basically never do them unless they are going to lose the property and they will get some equity by doing it and their credit is already trashed.. this was the model that i ran for all my sub 2 when foreclosure rescue sub 2 was legal in OR and WA. big times laws now..

We have about 1,000 square feet of carpeted floor that we'd like to convert to tile.
