What to check first (before you act)

Goal and timeline

Before you even look at listings, define what you want. Are you looking for a starter home, a place to raise a family, or a retirement property? Your timeline is also crucial. Are you hoping to move in six months, a year, or longer? This will influence how aggressively you save and what you can afford.

Current cash flow

Understanding your monthly income and expenses is paramount. Where does your money go each month? This analysis will reveal how much you can realistically allocate towards a mortgage payment, property taxes, homeowners insurance, and potential HOA fees.

Emergency fund or safety buffer

Owning a home comes with unexpected expenses. Before committing to a mortgage, ensure you have a robust emergency fund. This typically covers 3-6 months of living expenses, including your potential new housing costs. This buffer protects you from unexpected repairs or job loss.

Debt and interest rates

High-interest debt can significantly impact your ability to qualify for a mortgage and your overall financial health. List all your debts, including credit cards, auto loans, and student loans, noting their interest rates. Prioritizing paying down high-interest debt can improve your credit score and free up cash flow.

Credit impact

Your credit score is a major factor in mortgage approval and interest rates. Check your credit reports from all three major bureaus (Equifax, Experian, TransUnion) for errors. Maintaining a good credit history by paying bills on time and keeping credit utilization low is essential.

Step-by-step (simple workflow)

1. Assess your finances and credit

What to do: Review your income, expenses, savings, and debts. Obtain your credit reports and scores.
What “good” looks like: You have a clear picture of your financial standing and know your credit score.
Common mistake and how to avoid it: Not checking credit reports for errors. Review them thoroughly to ensure accuracy.

2. Determine your budget

What to do: Use online mortgage calculators and consider your debt-to-income ratio to estimate how much you can afford.
What “good” looks like: A realistic monthly housing payment range that fits comfortably within your budget.
Common mistake and how to avoid it: Only considering the principal and interest payment. Remember to include property taxes, homeowners insurance, and potential HOA fees.

3. Get mortgage pre-approval

What to do: Apply for pre-approval with multiple lenders to compare rates and terms.
What “good” looks like: A pre-approval letter stating the maximum loan amount you qualify for.
Common mistake and how to avoid it: Applying for multiple loans simultaneously without understanding the impact on your credit. Space out applications to minimize credit score dings.

4. Save for a down payment and closing costs

What to do: Set a savings goal for your down payment and closing costs, which can include fees for appraisal, title insurance, and more.
What “good” looks like: You have accumulated the necessary funds for your down payment and estimated closing costs.
Common mistake and how to avoid it: Underestimating closing costs. Research typical closing cost percentages in your area.

5. Find a real estate agent

What to do: Interview and select a buyer’s agent who understands your needs and local market.
What “good” looks like: A trusted agent who actively helps you find suitable properties and represents your interests.
Common mistake and how to avoid it: Not interviewing multiple agents. Choose someone you feel comfortable with and who has a good track record.

6. Search for homes

What to do: Work with your agent to view properties that meet your criteria and budget.
What “good” looks like: You’ve identified a few homes that you are seriously considering.
Common mistake and how to avoid it: Falling in love with a house before confirming it meets all your practical needs. Focus on location, condition, and suitability.

7. Make an offer

What to do: Submit a written offer with your agent, including the purchase price, contingencies, and desired closing date.
What “good” looks like: A well-structured offer that reflects your understanding of the market and your priorities.
Common mistake and how to avoid it: Including too many or too few contingencies. Your agent can advise on what’s standard and advisable.

8. Negotiate and accept an offer

What to do: Be prepared to negotiate price, terms, and repairs with the seller.
What “good” looks like: Both buyer and seller have agreed to the terms, and a purchase agreement is signed.
Common mistake and how to avoid it: Getting too emotional during negotiations. Stick to your budget and priorities.

9. Secure your mortgage

What to do: Formally apply for the mortgage with your chosen lender, providing all necessary documentation.
What “good” looks like: Your mortgage application is in process, and you’re working with the lender to meet their requirements.
Common mistake and how to avoid it: Making large purchases or opening new credit lines during this period. This can jeopardize your loan approval.

10. Home inspection and appraisal

What to do: Hire a professional home inspector to assess the property’s condition. The lender will order an appraisal to determine the home’s market value.
What “good” looks like: The inspection report identifies any significant issues, and the appraisal meets or exceeds the loan amount.
Common mistake and how to avoid it: Skipping the home inspection. This is your chance to uncover hidden problems that could be costly later.

11. Final loan approval and closing disclosure

What to do: Your lender will issue final loan approval. You’ll receive a Closing Disclosure detailing all final loan terms and costs.
What “good” looks like: You have final loan approval and have reviewed the Closing Disclosure carefully.
Common mistake and how to avoid it: Not reviewing the Closing Disclosure thoroughly. Compare it to your Loan Estimate and ask questions about any discrepancies.

12. Closing

What to do: Sign all final paperwork, pay your closing costs and down payment, and receive the keys to your new home.
What “good” looks like: All documents are signed, funds are transferred, and you officially own your home.
Common mistake and how to avoid it: Not bringing the required funds in the correct form (usually a cashier’s check or wire transfer). Confirm the exact amount and acceptable payment methods beforehand.

Decision rules (simple if/then)

• If your credit score is below 620, then focus on improving it before applying for a mortgage because many lenders require higher scores.
• If you have significant high-interest debt, then prioritize paying it down before buying a house because it improves your debt-to-income ratio and frees up cash.
• If you have less than a 20% down payment, then research FHA or VA loans or consider private mortgage insurance (PMI) because these options can help you buy with less upfront cash.
• If you are considering an adjustable-rate mortgage (ARM), then understand how much your payments could increase if interest rates rise because this can lead to unexpected budget challenges.
• If the home inspection reveals major structural issues, then you may need to renegotiate the price, request repairs, or walk away from the deal because these problems can be very expensive to fix.
• If you are buying in a desirable market with competitive offers, then you might need to make an offer with fewer contingencies to be competitive because sellers often prefer less risk.
• If you have a stable job and plan to stay in the home for many years, then a fixed-rate mortgage is often a good choice because it provides predictable payments.
• If you are struggling to save for a down payment, then explore first-time homebuyer programs or assistance options because these can reduce the upfront cash needed.
• If your debt-to-income ratio is high, then consider delaying your purchase or paying down debt because lenders use this ratio to assess your ability to repay a loan.
• If you are unsure about the market value of a home, then rely on the appraisal and your agent’s expertise because these provide objective data.

FAQ

What is mortgage pre-approval?

Pre-approval is a lender’s conditional commitment to lend you a specific amount of money based on a review of your financial information. It gives you a clear idea of your borrowing power.

How much down payment do I need?

The required down payment varies. Some loans allow as little as 3.5%, while others may require 20% or more to avoid private mortgage insurance (PMI). Check with lenders for specific requirements.

What are closing costs?

Closing costs are fees associated with finalizing a mortgage and transferring home ownership. They typically range from 2% to 5% of the loan amount and include items like appraisal fees, title insurance, and lender fees.

What is private mortgage insurance (PMI)?

PMI is an insurance policy that protects the lender if you default on your loan and have less than a 20% down payment. You pay a monthly premium for it.

Should I get a fixed-rate or adjustable-rate mortgage?

A fixed-rate mortgage offers a stable interest rate and payment for the life of the loan. An adjustable-rate mortgage (ARM) starts with a lower rate that can change over time, potentially increasing your payments.

What is an escrow account?

An escrow account is managed by your lender to hold funds for property taxes and homeowners insurance. They collect a portion of these costs with each monthly mortgage payment and pay them on your behalf when due.

The process can take anywhere from 30 to 90 days or even longer, depending on market conditions, lender processing times, and any unexpected issues that arise.

What is earnest money?

Earnest money is a deposit you make when submitting an offer to show the seller you are serious about buying the home. It’s typically held in an escrow account and applied towards your down payment or closing costs.
