Title Companies, Lenders, and MLSs

Be the Partner Realtors Brag About.

Instant, self-serve Proof of Funds letters—allow Realtors to show homes with confidence, even before a pre-approval is in place.

You’re not just helping them stand out—you’re helping them stay safe, build trust, and win in a competitive market.

How to use it

For MLSs

Empower Members, Champion Fair Housing

Aster Key uses only 100% homebuyer-permissioned, verified data. Never personal data from data brokers, such as by typing in a consumer’s phone #, or used without consent.

For Title Companies

Strengthen Realtor and Lender Relationships

With Aster Key, your title company can provide Realtors and Lenders with instant, identity-verified Proof of Funds letters. This helps qualify buyers faster and positions your company as a trusted partner from customer acquisition to close.

For Lenders

Gain Early Visibility and Support Realtor Partners

Equip Realtors with a secure, real time Proof of Funds tool. Use Aster Key to demonstrate your commitment to service and connect with borrowers earlier – right when they’ll need pre-approvals and financing.

Why Offer Aster Key?

Real estate agents can share the app, enabling homebuyers to generate a Proof of Funds letter in under 5 minutes. This is ideal when there’s no time for a pre-approval letter, such as during a weekend or evening showing request. Homebuyers can verify their assets and identity right from their car!

Enhance the value of your services and cultivate stronger partnerships with Realtors. Proof of Funds letters often lead to follow-up pre-approval letters, since the data is generated directly by the homebuyer.

Minimize risks like theft during showings—ne’er-do-wells won’t complete identity checks or asset verification just to get inside.

Verified Proof of Funds letters assure sellers that only qualified buyers are touring their homes. A powerful tool for Realtors to highlight in listing presentations.

Aster Key is entirely homebuyer-permissioned, eliminating Fair Housing risks tied to apps that rely on inaccurate public data and biased assumptions. Some apps even use a homebuyer’s phone number to gather data without consent!
