Rocket is offering a Visa Signature card, the card’s unique feature is that it earns 5% back on all purchases towards a new mortgages closing and 2% back on all purchases toward an existing mortgage (and 1.25% as a statement credit). You’re limited to $8,000 towards mortgage closing costs.
This obviously locks you into using Rocket for your home loan and because of that I wouldn’t recommend it. If there was no cap on the 5% then maybe it would be worth considering.
