If you are in Edmonton next Tuesday evening, we are having a "wholesale expert team" give a talk at a local investment club. This couple do wholesaling full time and work very hard to be successful. Last month we had a successful local Rent To Own specialist.
Find others out in your local area who wholesale and ask lots of questions. Take Ron LeGrand's courses. Avoid some of the other "real estate guru" who offer special courses on Real Estate, American style.
The number of deals will depend on the local market and economy, so if you start in wrong part of the market cycle, you will starve before your first deal.
For every ten people I have met who do wholesaling, only one is still doing the strategy next year.
