The Mortgage Timeline Explained: From Pre-Approval to Keys in Your Hand

The Full Mortgage Timeline Step-by-Step

Step 1: Pre-Approval (1–3 Days)

Before you tour homes, get pre-approved. This means a lender has reviewed your:

• Credit score
  
• Income and assets
  
• Employment history
  
• Debt-to-income ratio
  

You’ll receive a pre-approval letter showing how much home you can afford—and sellers won’t take you seriously without it.

Step 2: Home Shopping & Offer Accepted (1–3 Weeks)

With pre-approval in hand, start touring homes. Once you find “the one,” your agent (ahem—like Invest by Ali) submits an offer. If accepted, escrow opens and the real fun begins.

Step 3: Loan Application Submission (1–2 Days)

Even though you’re pre-approved, now’s the time to formally apply. Your lender locks your rate, starts processing your documents, and preps for underwriting.

You’ll provide:

• Pay stubs, bank statements, tax returns
  
• ID and employment info
  
• Details on the home you’re buying
  

Step 4: Home Appraisal & Inspections (1–2 Weeks)

Your lender orders an appraisal to ensure the home is worth what you’re paying. This can take 5–10 business days. At the same time, schedule inspections to check for repairs or red flags.

Invest by Ali’s Tip: If the appraisal comes in low, don’t panic—we’ll help you negotiate or challenge the value.

Step 5: Underwriting (7–10 Business Days)

The underwriter reviews your entire file—credit, income, appraisal, etc.—to confirm you meet all loan requirements. You may get a “conditional approval”, meaning they need a few more items before giving the green light.

Stay ready to send updated pay stubs, letters of explanation, or account info fast.

Step 6: Clear to Close (1–3 Days)

Once underwriting is complete and all conditions are met, you’ll get the magic words: “Clear to Close.” Your lender finalizes the loan docs and sends everything to the title company.

Step 7: Closing Day (1 Day)

You’ll review and sign final paperwork, wire any closing funds, and—once the loan funds and the deed is recorded—you get the keys. Congrats, homeowner!

What Can Slow Down the Mortgage Timeline?

• Missing or outdated documents
  
• Last-minute credit changes (like opening new accounts)
