What's going on Anthony,
This is quite the thread with many different responses. I'm a full time wholesaler and here are my 2 cents.
I am currently spending about $20,000 a month in marketing - spending this amount of money positions me to run a more predictable business (although nothing is guaranteed in any business.)
Would I say that one needs this kind of budget in order to do their first deal? Absolutely not.
I didn't start off with these kinds of funds in the beginning, I am a first generation American with no college degree.
My first deal came from a a hand written letter, I had no marketing budget.
However it took me months of preparation and constant rejection, this business is FAR from easy.
Although I didn't have the funds this is what I did have:
Ambition, time, a growth mentality, sales background, focus, aptitude for business, no other option but to succeed.
What I sacrificed:
Eliminated all distracting relationships, cut out music for a year and listened to podcasts, 12 working hour days, 1-2 books on real estate a month, reinvested profits into real estate seminars.
As far as your question regarding "what seller would sell at a discount?"- just remember that when you do wholesaling correctly you are a listener more than anything.
Lowballing is not the name of the game, it's all about listening.
If you ask the right questions a homeowner will tell you how much they NEED in order to ink a deal.
No matter how much it confuses people, the reality is that there will ALWAYS be a market for convince. Every day thousands of cars are sold to car dealerships at a discount, is it because car owners didn't know they could sell it for more on Craigslist? It would be foolish to believe so, its all convenience.
Disregard all negative thoughts/ outside opinions - focus on growing in this business and most importantly just know it's possible.
Best of luck.
