Common Mistakes Homebuyers Make

Avoiding common pitfalls can save time and money:

1. Overlooking Total Loan Costs

Focusing solely on interest rates without considering fees and closing costs can lead to unexpected expenses.

How to Avoid:

Request a detailed Loan Estimate from each lender to ensure you understand all costs involved.
Compare the Annual Percentage Rate (APR), which includes both interest and fees.

2. Ignoring Loan Terms

Not fully understanding loan terms, such as prepayment penalties or adjustable-rate features, can lead to future complications.

How to Avoid:

Read all loan documents carefully.
Ask your lender to clarify any terms you don't understand.

3. Failing to Lock in a Rate

While locking in a rate can be beneficial, it should only be discussed after the application is fully submitted and approved.

How to Avoid:

Discuss rate lock options with your lender after submitting your documents.

4. Failing to Shop Around

Accepting the first offer without comparing can lead to missed opportunities for better terms.

How to Avoid:

Obtain quotes from at least three different lenders.
Consider both national and local lenders for a comprehensive comparison.
