What's the difference between 0% financing and a deferred interest promotion?

With a true 0% APR plan, your monthly payments go entirely toward principal, and no interest is ever charged as long as you meet the plan's terms. A deferred interest promotion can look similar upfront, but interest actually accrues in the background. If the balance isn't paid in full by the end of the promotional window, all of that deferred interest gets charged retroactively. It's worth asking any contractor which type of plan they're offering. Douglas Construction is upfront that our 0% financing options are true 0% APR, not deferred interest.
