The length of time it takes to get a loan approved online will vary depending on the lender. Generally, the process is quick and may take as little as minutes for approval. However, some lenders may require additional documents or information which could result in longer processing times. Additionally, if you are applying for a loan with bad credit, it may take longer to receive approval than with a traditional lender. It’s important to compare different lenders before applying in order to ensure that you find the one that meets your needs while providing the quickest turnaround time possible.
