Its a very niche part of RE. 

And since i have a very specific niche and pricing structure I am always the last one they call and the clients usually have run out of time and are going to lose the deal and their deposit if they cant close in 3 to 5 days.. :)  So i turn them to yes or no in 24 to 48 hours so i dont hold anyone up.Just had one today  Pacific Palisades land deal  appraised 50mil but guy will take 20 mil if we can close in 10 working days.. needs dough for a deal in Vegas..

There are some other things you should do after you make your selections of your niche and market ares.  

Is brokering, or a listing agreement.Personally, I don't think either are technically wholesaling and would not call either one wholesaling ...

Read books on investing in real estate, listen to the podcasts, attend webinars and stay active on the forums while connecting with other investors in your area and pick a niche.

You technically buy the property with the buyers money, hold it for a good 5 mins and then pay the seller. 

Technically you will not "share" a wall in spite of how it looks, technically there are typically two complete walls... they just touch and good luck separating them after 15 years.

So technically no the mortgage company sends it to a management company and they assign it in most cases.
