You have three main sources, each with trade-offs:
Online Lenders (SoFi, LendingClub, Upstart, Prosper, Avant) — Typically offer competitive rates, fast approval (sometimes same-day), and a fully digital application. Online lenders often use alternative data (education, employment history) in addition to credit scores, which can benefit borrowers with thin files. Best for: convenience, competitive rates, quick funding.
Banks (Chase, Wells Fargo, Citi, US Bank) — If you already have accounts at a major bank, you may get a loyalty discount or streamlined application. Bank rates are often competitive for existing customers with good credit. Best for: existing customers, larger loan amounts, relationship pricing.
Credit Unions (local or employer-based) — Credit unions are nonprofit, which often translates to lower rates and more flexible qualification criteria. They may also offer small-dollar loans that banks don't. The downside is a slower process and the requirement to become a member. Best for: lower rates, more flexible qualification, personal service.
Tip: Always get quotes from at least 3 lenders. Most allow you to check your rate with a soft credit pull (no impact on your score) before formally applying. Use these pre-qualification offers to compare before committing.
