Wholesaling is best in a buyer's or seller's market?

[James Mangum]

Shall I choose a hot, neutral, or cold market for wholesaling? I'm sure some of you will say, "It doesn't matter; just get started." But, perhaps it does matter. I'm wondering what the veteran and/or active wholesalers have to say about this. All things being equal (which of course, they're not), which type of market is more productive?
