10 Things You Must Know Before Buying a Home

Practical steps to help you prepare for one of the biggest purchases of your life.

Buying a home is one of the most exciting—and significant—decisions you’ll ever make. Whether you’re looking for your forever home, an investment property, or your first condo, the process can feel overwhelming without the right preparation. The good news? With a little upfront planning and the right guidance, you can move forward with confidence.

Below, we’ll walk you through the essential things to know and do before making that leap. Let’s dive in!

1. Understand Your “Why”

Before jumping into the home-buying process, take a step back and understand why you’re making this purchase.

Are you buying a home to build equity instead of renting?
Do you need to relocate for a new job or growing family?
Is this property an investment for long-term wealth building?

Clarifying your purpose helps you narrow down the type of property, location, and features that align with your vision.

2. Check Your Financial Readiness

✅ Know Your Credit Score

Your credit score plays a crucial role in determining loan eligibility and interest rates.

Request a copy of your credit report and resolve any errors before applying for a mortgage.

✅ Get Pre-Approved for a Loan

A pre-approval letter shows sellers you’re serious and helps you understand how much home you can afford. Steps include:

Searching online for reputable lenders to compare interest rates.
Asking a trusted real estate agent for lender recommendations.
Submitting necessary documents (tax returns, bank statements, W-2s, pay stubs) for verification.

✅ Factor in All Homeownership Costs

Owning a home isn’t just about affording the purchase price. Additional costs include:

Down payment (typically 3%–20% of the home’s price)
Closing costs (title, escrow, and legal fees)
Property taxes & homeowners insurance
Monthly mortgage payments
Maintenance & repairs
HOA fees (if applicable)

3. How Much Do You Need to Save?

A common home-buying mistake is underestimating the actual costs involved. Here’s what to look at:

✅ Safe Income-to-Debt Ratio

Lenders examine your debt-to-income ratio (DTI):

Overall DTI below 36% (includes mortgage + car loans, credit cards, etc.)
Housing DTI under 28% (housing payments shouldn’t exceed 28% of your gross monthly income)

For instance, if you earn $7,000 per month before taxes, keep total debt under $2,520 and housing costs under $1,960.

✅ Additional Financial Considerations

Most buyers spend a significant portion of their savings on:

Down payment (3%–20%)
Loan points (used to buy down interest rates)
Closing costs & acquisition fees
Buyer’s representative fee (~3%)
Lender-required reserves (1%–3% of the purchase price annually)

Since these costs add up quickly, many buyers negotiate for the seller to pay their agent’s commission, wrapping it into financing. However, reserves are always the buyer’s responsibility.

4. Research Locations Carefully

Even if you find the perfect home, a bad location can turn it into a regretful purchase. Consider:

✅ Commute times & nearby public transportation
✅ School district ratings (even if you don’t have kids—resale value matters!)
✅ Proximity to shopping centers, parks, medical facilities
✅ Crime rates & local neighborhood trends
✅ Future development plans in the area

Pro tip: If you’re considering multiple locations, visit at different times of the day to assess traffic, noise levels, and the overall neighborhood feel.

If you or someone in your household has a respiratory condition like asthma, it’s especially important to pay attention to the environment. For example, in places like Oʻahu, Hawaiʻi—a volcanic island—many residential areas are built around ridges and valleys that create unique microclimates. Some neighborhoods, like Manoa, are known for their beautiful greenery—but that also means higher humidity.

My broker-in-charge once shared her personal experience living in Manoa—she didn’t even know she had asthma until she lived there. The humidity triggered her symptoms that she eventually had to move out. She told me this as a tip because I also have pretty bad asthma, and I genuinely appreciated that level of care and attention to detail.

This kind of thoughtful advice is exactly why it matters to work with an agent who not only knows the market, but also cares about your well-being—even after escrow is over.

5. Work with a Knowledgeable Real Estate Agent

Don’t ever pick your real estate agent based on friendship. You’re about to make one of the biggest purchases of your life, so finding a good agent really matters. Choose an agent based on experience, market knowledge, and communication skills, not personal relationships.

I’ll share tips in a future blog post on how to distinguish a great agent—believe it or not, there are more bad agents out there than good ones!

6. Make a Wants vs. Needs List

Avoid getting caught up in unnecessary features. Instead, create two lists:

Must-Haves:

✔ Right number of bedrooms & bathrooms
✔ Sufficient square footage
✔ Safe neighborhood
✔ Good resale potential

Nice-to-Haves:

✔ Large backyard
✔ Home office or gym space
✔ Smart home technology
✔ Swimming pool

This framework keeps you focused and prevents impulsive decisions.

7. Spend More Time at Open Houses

Go to open houses every week to educate yourself about the real estate market. In Honolulu, public open houses are on Sundays from 2–5 PM (basically after church). If there’s a property you’re planning to make an offer on, consider staying for the entire open house. Why?

Bug & Neighbor Situations:
- A neglected neighbor’s yard with standing water can lead to mosquito issues—especially if the home has lots of open windows or no screens (common in places like Hawaiʻi, where airflow is prized).
- Imagine you have a baby and mosquitos constantly fly in because windows aren’t fully shielded. That can be a big disturbance.
Noise Levels & Potential Disturbances:
- Barking dogs can be far more annoying if the neighbor does nothing about them.
- Loud music or frequent construction can also become daily headaches.
Conversations Overheard:
- Neighbors sometimes ask the listing agent things like, “Is there a marching band sound here too? I hear it every morning!”
- Some neighbors may know the history of the property or the seller. If there’s any concerning backstory—like previous criminal activity—it’s often the neighbors who bring it up, and they usually mention it right away. They may also point out modifications made to the home, especially if their unit shares the same floor plan.
- That kind of insight is priceless—and you’d never catch it during a quick 10-minute visit.

Spending a little extra time can help you avoid unpleasant surprises down the road.

8. Be Emotionally and Logistically Prepared

Buying a home can be an emotional rollercoaster. You may face:

🚨 Competitive bidding wars
🚨 Rejected offers
🚨 Houses that look great online but disappoint in person

Stay patient and trust the process.

Market Insight: Real Estate Moves FAST 🚀

Escrow typically lasts around 30 days, sometimes even shorter.
Because the market moves quickly, consider studying local prices and home values for at least a year before jumping in.

9. Don’t Skip the Home Inspection

Always hire a professional inspector—this is the only way to prevent a nightmare. Never inspect by yourself!

A thorough home inspection reveals hidden problems such as:

✔ Foundation issues
✔ Roof damage
✔ Plumbing or electrical problems
✔ Mold or water damage

Questions to ask your inspector:

What issues does the property have, and how urgent are they?
Is it expensive or difficult to repair? (Remember, cost includes time for fixing it, too!)
How long might the repairs take?
Would YOU buy this property based on its condition?

Don’t be afraid to ask every question that comes to mind—that’s why you’re hiring a pro!

10. Megan’s Law: Know Your Neighborhood (If It Matters to You)

Safety is a top priority for many buyers. In the USA, Megan’s Law allows the public to access information about registered sex offenders in a given area.

How to Use It:
- Search online for your state’s “Megan’s Law” or “sex offender registry.” You’ll usually be able to input a specific address or ZIP code to see if there are registered offenders nearby.
- Don’t be shocked if you find more listings than you expected—sex offenders can live in many places you wouldn’t immediately suspect.
Living Near Schools:
- In Hawaiʻi (and many other states), laws often prohibit registered sex offenders from living within a certain distance of schools or daycare centers. If this issue is important to you, consider buying a home near a school—it may offer a built-in protective radius.
- Always check local and state laws, as requirements and restrictions can vary by location.

Being aware of your surroundings helps you make an informed decision about where you want to live—and what kind of community you’ll be part of.
