Starting a real estate wholesale business can be a great way to enter the world of real estate investing, but it does require some preparation and resources. Here are a few things you should consider having before you begin:

1. Capital: Wholesaling real estate requires some initial capital to get started. You'll need money to cover expenses such as marketing, inspections, and closing costs. It is recommended to have some liquidity to cover operational expenses and closing costs, even if a deal doesn't close.

2. Network: Building a network of real estate professionals, such as real estate agents, contractors, and other investors, is crucial for success in the wholesale business. These connections can help you find deals and resources you may not have access to otherwise.

3. Education: It's essential to have a solid understanding of the real estate market and the legal and financial aspects of real estate investing. You should also be familiar with the wholesale process, including how to find and evaluate properties and how to market them to potential buyers.

4. Marketing: Having a solid marketing plan in place is critical for any business, and wholesale real estate is no exception. Identifying potential buyers and getting your properties in front of them is essential for success. Investing in your marketing skills and outreach can help you get the best possible results and work more efficiently.

5. Flexibility and Patience: You must be prepared to be patient and flexible in this business. Wholesaling can take some time, and you may not find a buyer right away, so be prepared to hold on to a property for a while if necessary. Also, be ready to pivot in your strategy when market conditions change.

6. Legal Documents and Contracts: Lastly, it is important to have standard purchase and sale agreements, option contracts, and other legal documents required to complete a wholesale transaction in your state. Consulting a real estate attorney can help you ensure that you have all the necessary paperwork in place.

Remember that this is not an exhaustive list, and depending on the scale and scope of your operation, you may need other resources. However, these are some of the most important considerations when starting a real estate wholesale business.
