As long as people are still buying and selling in a market you can still be successful in wholesaling if you understand one important principle:
Price overcomes all objections.
If the price of the house you are selling is cheap enough, someone will buy it. I know that's a no-brainer, but its what the ENTIRE concept of wholesaling is based on.
Price overcomes ALL objections.
But the markets slow and the mortgage industry is falling apart, well price overcomes ALL objections. Now what that price needs to be to overcome those objections will be dependent on your current market, and that's what a wholesaler needs to know.
Listen, you can make excuses why NOT to do this for the rest of your life. You can go right up to your grave excusing your lack of success or you can just get out there and do it. There is a certain level of education and analysis you MUST have to be successful in this business, but the number one reason people fail in this business is because they talk themselves out of ever doing anything. Most real estate " investors" never buy a single house. Don't by one of them. I urge you to never be " with those cold and timid souls who know neither victory nor defeat."
