Wholesaling real estate is a fast-paced investment strategy where investors find lucrative real estate deals and assign the contracts to other buyers for a fee. It involves identifying distressed or undervalued properties, negotiating favorable terms with the seller, and then quickly transferring the contract to another investor. This allows wholesalers to make profits without the need for large sums of money or long-term property ownership. It's a popular method for generating income and building a network within the real estate industry.
