King County does have some data hubs that may allow you to download that data en masse.  

Your bank will tell you the best way.)I believe there are some downloadable Excel spreadsheets in the Forms section of Bigger Pockets. 

@Eric Hrlbock There are several move out itemized lists with charges in the file place here on biggerpockets that you can download. 

There is even a downloadable calculator that will tell you the approximate value of any house based on the MSA, zip code, purchase price, purchase year and today's date. 

If someone here personally, or on the forums, would invest their time with me and give me a complete and total information download session, I would be more than greatful!  

Once I got my spreadsheets in order it's now easier to add a property to it for my expense/profit tracking.I'm still not sold on just keeping paper or tossing all the paper and keeping just electronic. big sigh :-o| i have "systematized" my process and it has actually helped me quite a bit. i do it all alone and then my wife goes through house by house expenses and creates a Cap Expense sheet that we just give to our CPA.here's' what i do:1. i enter the charge in Quicken PM and tag the property2. i scan the receipt and put it in a folder that's specifically for Recepts-2016-March-$55.42-HD-3-8-16.pdf or .jpg3. then i toss the receipt in the garbage.4. once or twice a month i back up my whole hard drive to another hard drive.this way if the IRS asks for a receipt, i can always find it. every now and then i lose a receipt and dont have it, but i have 99.8% of all receipts.btw, i keep track of 28 or so properties.does that help?

You can also download the app for a nominal cost.

After getting my receipts, I scan them into PDFs and organize them into property folders.Example folder structure:Property - 123 Main St-- Applications (keep applications on file in electronic format on advice from attorney -- two years is the statute of limitations for discrimination suits)-- Contractors and Receipts (contains scans of contractor invoices and scanned receipts)-- Insurance (contains policy declaration pages, invoices, etc.)-- Pictures (I like before/after pictures, pictures I use for marketing the rentals)-- Purchase (closing documents, settlement statement)-- Taxes (property tax bills and receipts)-- Tenants (information on tenants such as leases, scanned copies of payments)-- Utilities (utility bills for gas, electric, water, sewer)
