Get Pre-Approved
A pre-approval certificate is the best way of demonstrating your ability to purchase a home. Pre-approval offers are also given stronger consideration by a seller than pre-qualification letters.
To issue you a Pre-Approved certificate, your mortgage advisor will ask you for annual income, time on job, time at current residence, permission to review your credit.
Once that's complete, and everything checks out okay, your letter can be in your hands so you can submit the best offer for your next home.
