Of course markets change and the chances of a profitable flip have changed as well.

Quote from @Rajagopalarao Paidi: Is there anyway to minimize or avoid agent costs, I don't have much scope for profit if I pay agent costs, what options typically one has Do it FSBO if you want to save them and then hire a TC or company to do the work...

The barrier to entry is lower so they seem attractive, and to the person who knows what they are doing, they can be very profitable.

A low price is no guarantee of profits. 

Nobody knows so what I do is making sure I'm profitable, even at rock bottom rents.

The possible lack of profit that is left behind.

This is maintained by the specific attorney’s office for the specific foreclosures they are performing.Although very profitable, Foreclosures are a poor choice for wholesaling, unless you have substantial capital.

You're going to need 15-20 duplexes that are considered good deals to get to that kind of profit.

Determine local/state laws regarding wholesaling and determine if (1) you need to be licensed in the jurisdiction you’re considering and (2) if you’ll be able to operate profitably while remaining legally compliant2.

You'd have to be a builder to really reap any sort of profits from an area as such.
