I predict that this will become more prevalent over the next 10 years as we all get older. 

Foreclosures are not a prevalent a well.

All I’m simply suggesting is that although there is low hanging fruit,as with any industry or niche, there are stressors or motivating circumstances that would lead a B class neighborhood to sell me their homes (outside of the current recovery efforts due to natural causes).InheritedDivorceJob lossTax delinquency To name a fewSome stressors are more prevalent in the areas you mentioned BUT C+ , B and A are not exempt.

I think it will be more prevalent in the future and we are just at the beginning of a gold rush, lots of opportunity, but scary also. 

Not sure if theft/crime is more prevalent in Dallas Ft.

An agent might be able to point you to parts of town where those are more prevalent. 

-Rentals will become more prevalent, but that means more homes will be owner by investors who, on the whole, tend to act more rational than an owner occupant and will invest rather than consume.

Drop bids were prevalent in AZ and NV and parts of CA during the high foreclosure times not so much here but 3 to 5 times a year I got a smoking deal.you had such a melt down in PHX and Vegas.. that 600k mortgages on houses that were done 100% financing and the bank knew the house would only sell for 300k if they got it back.. so they just dropped the bids accordingly instead of bringing them on the books.
