Common Mistakes Homebuyers Make

When refinancing to consolidate debt, avoid these common pitfalls:

1. Overlooking Closing Costs

Refinancing involves closing costs that can offset potential savings.

Failing to align refinancing decisions with future financial plans can be detrimental.

Impact: Unexpected life changes may affect your ability to maintain mortgage payments.

Refinancing can temporarily affect your credit score.
