How Much House Can I Afford?

Understanding Your Home Affordability in Lake Oswego

Buying a home in Lake Oswego is an exciting journey, but it also represents one of the most significant financial decisions you will face. Before diving into property listings or scheduling tours, it's essential to consider one key question: How much home can I comfortably afford? This goes beyond what a lender may approve or what an online calculator suggests. It should align with your personal life, financial goals, and long-term plans. Let’s break it down step by step.

Step 1: Identify the Three Key Numbers

When assessing affordability, three main factors come into play:

Your Income: This encompasses your base salary, bonuses, commissions, and any other consistent income streams. Lenders primarily look at your gross monthly income before taxes.

Your Monthly Debt: This includes car payments, student loans, credit card balances, personal loans, and any other recurring financial obligations. Lenders analyze your debt-to-income ratio (DTI) to evaluate your financial health.

Your Down Payment: The larger your down payment, the lower your monthly payments will be, which may also lead to better loan terms.

Step 2: Familiarize Yourself with the Basic Formula

A common guideline is the 28/36 rule, which suggests that no more than 28 percent of your gross monthly income should be allocated to housing costs, and no more than 36 percent should go toward total monthly debt, including housing. However, this formula does not take into account personal factors such as your lifestyle, savings objectives, childcare expenses, private school tuition, travel plans, or investments. It serves as a framework rather than a comprehensive strategy.

Step 3: Calculate Your True Monthly Payment

Your actual housing expenses extend beyond just principal and interest. You should also consider property taxes, homeowners insurance, homeowners association (HOA) dues, mortgage insurance (if applicable), and maintenance reserves. A home priced at $700,000 in Lake Oswego can have significantly different monthly costs based on its location, tax rates, insurance premiums, and loan structure. Relying on estimates can lead to surprises. To run your own calculations, visit the Mortgage Calculators section in our Resources dropdown. Here, you can explore various price points, down payment amounts, and interest rate scenarios to see how your payments would change.

Step 4: Reframe Your Question

Instead of asking, “How much can I afford?” consider asking, “What monthly payment will support the life I envision?” Think about whether you want to maximize retirement contributions, plan to invest in real estate in the future, are growing a business, or if you value liquidity over committing all your resources to a down payment. Affordability should align with your broader financial vision, not just the maximum loan amount.

The Limitations of Online Calculators

Online calculators often make assumptions, such as stable income, standard tax situations, clean credit profiles, and straightforward employment structures. They do not account for bonus income, self-employment scenarios, diverse down payment strategies, or the long-term wealth implications of your choices. While they provide mathematical calculations, they do not facilitate strategic planning.

Do we make an offer and hope everything works out? Do we wait and risk losing the home? Do we rush our current home onto the market? Unfortunately, this is where many homeowners find themselves.

When most people look at a mortgage payment, they only see what it costs today. But that may not be the best question. A better question could be: What will this same payment feel like 10 years from now?

The housing market is changing… and most buyers haven’t caught up yet. For the past few years, sellers had all the control. Homes sold fast. Buyers competed aggressively. And negotiating power was almost nonexistent. That’s no longer the case. Today, we’re seeing a clear shift toward a more balanced market, and that creates opportunity if you know how to use it.
