We almost never buy under $30,000 houses (and by this, I mean $30,000 all in, not purchase price), primarily for two reasons:1) As you mentioned, areas with <$30,000 house generally have higher crime, more delinquency and tenant damages.But also 2) These types of properties can't sustain such losses as easily.

If I didn’t have the luxury of the income, it wouldn’t be sustainable, but with the physician income it’s something I think that is worth stomaching.I saw people saying I should invest in commercial for medicine or move to other types of investment.

Partner A: Owns and runs a business, has comfortable consistent cash flow to sustain estimated payments for such a property but minimal credit history. 

How do I get this property under control, self sustaining, and running smooth so I can start hunting for the next deal?     

I know some of the mobile parks in Deer Park and north sustained major damage.  

I can't tell you whether you should make the deal or not, negative cash flow is difficult to sustain, but as long as you reasonably know you'll keep your job until you can refinance, it seems doable.

I sure dose not seem sustainable I wonder what percentage of bond buying is long term hold and what percentage is speculative buyers.  

B&H is a great strategy . . . just make sure you have a steady plan, adequate financial resources to sustain the property through tough times, and a fair knowledge of local renter/landlord laws.

Wholesalers have little to offer sellers in Portland so you have to have a very wide net (lots of marketing $) to make wholesaling a sustainable business model. 

So I sold all of my toys and got into investing into real estate as a path to a sustainable retirement.
