I stumbled across a single family house with a mother in law suite with outdoor entrance, kitchen, bathroom only 10 minutes after being listed on Zillow. 

I can't make a rental deal pencil within Seattle proper if there isn't a second entrance/kitchen/dwelling unit. 

Grant, if the house is vacant and liveable, I generally find that a sign in the yard which says "House for Sale....Owner Financed" plus a few more at the entrances to the neighborhood, is sufficient to get my phone ringing off the hook.Does the local Real Estate Lawyer happen to be Scott Horne?

If you plan on duplexing consider that because seperate entrances are key and to have to build a staircase down to the ground from above or cut into an existing foundation is a lot of $ needed to spent that can be avoided.

I am attempting to lay out my financial path to semi-retirement (i.e. leaving my current w2 for something less time consuming/more enjoyable) within 10 years or less.I can identify my family's spending now and what I project after semi-retirement, which I have done for the most part BUT that part of working backward and laying out milestones to achieve x number of properties or cash flow or equity, all the while maintaining a proper amount of contribution in my workplace retirement plan and other tax adv/def approaches.I imagine i'd need a tax resource and a financial advisory resource, both of whom are knowledgeable on the notion of 1) real estate and 2) retirement planning before traditional age.

The furnishings are high end, separate entrance, etc and would attract a wealthier tenant.

Had a large dirt pile on it and someone had dug some dirt from the entrance, leveling the entrance.7.  50% of all the storage for the town was in a location 4 miles out of town on a highway all by itself. 

Also if one had a basement, perhaps egress private entrances could be used so the basement could become a few condos.  

I'm surprised at how egress entrances seem to be often ignored by house hackers.
