The Biggest Mistakes First-Time Home Buyers Make (And How to Avoid Them)

[Minho Lee]

There’s a lot of excitement around buying your first property, but what separates a good decision from a costly one is how you approach it behind the scenes.

One of the biggest things I’d suggest is to always underwrite conservatively. Don’t rely on best-case scenarios, build in buffers. A simple example is using a 5% vacancy rate, expenses like insurance don’t stay fixed forever, they tend to increase over time, so factoring that in early will give you a more realistic picture.

Having reserves is another key piece. While it's not required, setting aside 3–6 months of PITI can protect you when unexpected situations come up. And they will. The same goes for CapEx, big-ticket items like roofs, heating systems, and plumbing aren't always immediate, but they're inevitable. Planning for them upfront can save you from getting caught off guard.

It’s also important to be ready before the right opportunity shows up. Getting pre-qualified, speaking with multiple lenders, and understanding your loan options will allow you to move quickly when a good deal hits the market.

And lastly, don’t be afraid to walk away. Not every deal is meant to be yours. Having the discipline to pass on something that doesn’t feel right is just as important as knowing when to move forward.

Buying your first property is a big step, but if you approach it with the right mindset and preparation, it can set the foundation for everything that comes after.
