Wholesaling is a simple strategy but it is by no means easy to carry out. It requires time, effort, and a good deal of knowledge about the areas of which to want to put houses under contract. You should know a fair amount of cost estimating to be able to recognize a good deal for the investors you'll be selling to, and you'll need some capital to not only run your business but maintain your standard of living until you start writing business.
Some people say that if you find a good deal the investors will come, but as a family man I prefer the piece of mind to have a buyers list and know exactly what it is my investors are looking for. It will take some time to do this as well.
Depending on how much capital you have to start, you might also consider getting your real estate license. Having this will give you access to a wealth of knowledge and information about the real estate scenery of your area. As a new investor, your license can potentially become an invaluable tool and speed up your development as an investor.
There's lots of information on wholesaling out there. The best advice I can give is to have a clear cut objective for your investment deal so it'll be easier to find what you're looking for.
Good luck and welcome to BP!
