Wholesaling vs. Flipping

[Michael S. Brooks]

I am a newbie and learning the ropes. I just finished the beginners guide and am deciding between wholesaling vs. flipping for my area of expertise. I have some experience with flipping, I recently flipped/sold a house (rehabbed down to the studs) so I was thankful to learn a bit during that process. One niche that peaked my interest during the beginners guide was wholesaling. I am continuing my education but am hoping for some quick guidance here:

What markets (city vs. suburb vs. rural) and dynamics (economics) are best for wholesaling? Massachusetts as an example.

Is there a particular sweet spot (lower end of the market vs. middle or high end) for doing high volume wholesaling?

From a marketing perspective how long is the ramp up to get your funnel flowing and which methods are most successful? Website vs. Direct Mail vs. Social Media

I am looking for income from either of these two methods 15k per month as an example.

Thank you for the guidance.
