The biggest mistake is house hunting without first securing mortgage pre-approval.
Picture this: you finally discover your dream home—it’s in the perfect neighborhood, with top-rated schools, and it checks every box on your list. But when it’s time to submit an offer, the seller requires a pre-approval letter before they’ll even consider it. Suddenly, you’re scrambling to gather paperwork and meet with a lender to confirm your qualifications. By the time you’re ready, another pre-approved buyer has already made an offer—and just like that, your dream home slips away.
Skipping Mortgage Pre-Approval
When you start touring homes without knowing your approved loan amount, you risk wasting time, setting unrealistic expectations, and missing out on opportunities.
Why Pre-Approval Matters More Than You Think
-
It tells sellers you’re serious.
-
It prevents heartbreak by narrowing your search to homes you can truly afford.
-
It speeds up the closing process.
Secondary Mistakes That Often Follow
-
Overestimating Budget and Ignoring Hidden Costs – Many buyers forget about taxes, insurance, and maintenance like landscaping, pool maintenance.
-
Neglecting Home Inspections – Skipping this step can lead to expensive repairs down the line. It is ALWAYS suggested to get a home inspection and to even be present on the day of the home inspection so you can go over everything with the inspector. I would even go further- some homes have pools, solar panels, water softener system, etc that inspectors will not even inspect. I would have a professional in that field inspect the items the inspector did not do a full evaluation on. This can save you thousands and for the very least, you have a better idea on what you may have to repair down the road.
-
Forgetting About Future Resale Value – Not considering neighborhood growth, school ratings, and future demand can seriously impact your long-term investment. And this is a big one! Even if you think, “This is my forever home—it’s everything I’ve dreamed of,” you still need to evaluate the development and surrounding area. For example, if neighboring homes show poor curb appeal, it could drag down your property value. Or if a large condo complex is scheduled to break ground next door, with dozens of windows overlooking your backyard, that dream home may not feel so dreamy in a few years. Sometimes, walking away is the smarter choice.
