The purchase price creates the spread and as an experienced rehab buyer, I know that by creating the necessary spread, all could go wrong and I could walk away clean if need be.As to the balance, lets continue this conversation/debate under the following peramiters so we can compare apples to apples.Lets say that the investor with the $500k is experienced in both buy/hold and flips.

The new Apple head quarters will be opened within minutes of this place and will hire 12,000 new employees!

Like every profession, there are good apples and bad apples.
