I have an interest in looking around in Oregon for tax sales, but it is obvious to me that I am woefully uneducated about these distinctions you guys have made.

If the answer is generally yes, you have yourself a bubble.These types of people are most often the biggest losers in a bubble because they are the last in and last out.I recall very distinctly speaking with a cab driver out in Toronto in 2007 who told me he was going to make his fortune buying crude oil futures.

@Joe Villeneuve Why do you make a distinction between "your cash" and cash you pull out after refinance?

Each metropolitan and geographic area has it's own specific and distinct market dynamics. 

Professions have a distinction different from vocations in that there is a greater knowledge required over the degree of skill and professions are taught through universities, where professors teach different aspects of study that give a student a broader basis of education.

“The courts apparently agree that the meaning of the words "trade or business" is uniform throughout the Code provisions here considered…No court has made an explicit distinction between a "trade or business" authority under one section of the Code and another under a different section.

Next 61.34 makes an important distinction between a "distressed home consultant" and a "distressed home purchaser", and between a "distressed home consulting transaction" and a "distressed home conveyance". 

I think you mean "distressed property", which 61.34 actually calls "distressed home".The distinction appears to be critically important in 61.34.

Grouping everything together into the "residential" category blends together crucially distinct data resulting in an arbitrary and bias answer.Govt financing, conservative underwriting and management execution properly combined; make multifamily (in my opinion exclusively workforce housing vs luxury, student, low income, etc) the BEST risk-adjusted return of all real estate asset classes.Any other (friendly) thoughts?

Of course, sometimes I pay the tenant for doing side jobs but it is always distinctly separate.
