LightStream
Tightest refi APR range in the market — but reserved for excellent credit. Same-day funding makes it the fastest close if you qualify.

Credit union refi with no prepayment penalty and a 0.25% rate discount for autopay. Loan-amount ceiling lower than marketplaces — best for under-$80K refi balances.
Editor's verdict
LightStream wins on raw APR; PenFed wins for member-discounted all-in rates.
LightStream's 5.24% refi APR floor is one of the lowest published rates in the market. PenFed's 6.49% baseline looks worse on paper, but after stacking 0.25% autopay + 0.25% direct deposit discounts, the effective rate hits ~5.99% — within striking distance. The tiebreaker: LightStream uses a hard pull immediately; PenFed offers soft-pull pre-qualification. Rate-shop with PenFed first.
- LightStream's published 5.24% floor is ~0.75% below PenFed's all-in rate.
- PenFed offers soft-pull pre-qualification; LightStream does not.
- Both lenders cap refi terms at 84 months and require 660+ FICO for prime approvals.
