Can you Trust Online Mortgage Calculators?

Jeff Johnson • June 19, 2024

You’d think an online calculator is a pretty straightforward device, one that you should be able to place your confidence in, and for the most part, they are. Calculators calculate numbers. The numbers are reliable, but how you interpret those numbers, not so much, especially if the goal is mortgage qualification.


If you rely on the numbers from a “What can I afford” or “Mortgage Qualification” calculator without talking to an independent mortgage professional, you’re going to be misinformed.


Don’t be fooled. Even though an online mortgage calculator can help you calculate mortgage payments or help you assess how additional payments would impact your amortization, they’ll never be able to give you an exact picture of what you can afford and how a lender will consider your mortgage application.


While mortgage calculators are objective, mortgage lending isn’t. It’s 100% subjective. Lenders consider your financial situation, employment, credit history, assets, liabilities, the property you are looking to purchase. Then, they will compare that with whatever internal risk profile they are currently using to assess mortgage lending. Simply put, they don’t just look at the numbers.


An online calculator is a great tool to help you run different financial scenarios and help assess your comfort level with different payment schedules and mortgage amounts. However, if you rely on an online calculator for mortgage qualification purposes, you’ll be disappointed.


The first step in the mortgage qualification process is a preapproval. A preapproval will examine all the variables on your application, assess your financial situation, and provide you with a framework to buy a property based on your unique circumstance.


Securing a preapproval comes at no cost to you and without any obligation to buy. It’ll simply allow you the freedom to move ahead with confidence, knowing exactly where you stand. Something a calculator is unable to do.


Please connect anytime if you’d like to talk more about your financial situation and get a preapproval started. It would be a pleasure to work with you.

Can’t Find the Right Home After You’re Pre-Approved? There’s Another Option The best place to start any home purchase is with a mortgage pre-approval. It gives you clarity around your budget and lets you shop with confidence. But what happens when you’ve been pre-approved, you know where you want to live—and nothing suitable fits your price range? This is a common challenge, especially for first-time homebuyers. Before buyer fatigue sets in, it may be worth considering a different approach: buying a home that needs work and financing the renovations as part of your mortgage . What Is a Purchase Plus Improvements Mortgage? A purchase plus improvements program allows you to buy a property and include the cost of approved renovations directly in your mortgage. This can be a great solution if: You can’t find a move-in-ready home within budget You’re open to renovations You want to customize the home from the start It opens up more options and can help you get into a location or property that would otherwise be out of reach. How the Process Works While the idea is straightforward, the process itself is structured and requires planning. Here’s a high-level overview: Renovation quotes are required upfront You’ll need detailed quotes for the work you want completed before final mortgage approval. Renovations must add value The lender must be satisfied that the improvements will increase the property’s value accordingly. Funds are reimbursed, not advanced You pay for the renovations initially. Once the work is completed and verified by an appraiser, the lender reimburses you and adds the cost to your mortgage. With the right guidance, this process is very manageable—but it’s important to understand the steps before committing. Is This Program Right for You? Purchase plus improvements isn’t for everyone. Buying a home is already a big undertaking, and adding renovations can increase stress—especially if timelines, budgets, or contractors become challenging. That said, if you’re financially prepared and like the idea of shaping the home to fit your needs, this program can be an excellent way to get more value and flexibility from your purchase. Final Thoughts If you’re struggling to find the right home after being pre-approved, you may not need to lower your expectations—you may just need a different strategy. If you’d like to explore whether a purchase plus improvements mortgage makes sense for you, feel free to connect. I’d be happy to walk you through the process and outline exactly what this option would look like in your situation.

Missed a Credit Card or Line of Credit Payment? Here’s What to Do If you’ve missed a payment on a credit card or line of credit and you’re worried about how it might affect your credit—or your future mortgage—this is for you. First things first: 👉 If you currently have an overdue balance, log in and make the minimum payment now. Seriously. Do that first. Everything else can wait. If You’re Only a Few Days Late Here’s the good news: Credit bureaus don’t record late payments until they reach 30 days past due. So if you missed a due date by a few days and paid it as soon as you noticed, it typically won’t show up on your credit report as a late payment—as long as you’re under the 30-day mark. That said, it never hurts to double-check. You can call your credit card company, explain what happened, and confirm the account is back in good standing. If you normally pay on time, they may even reverse the interest charged. It doesn’t hurt to ask. If You’re 30, 60, or 90 Days Behind If payments have gone past 30 days, your credit has likely been impacted—but the situation is still fixable. The most important step is to: Bring all accounts current as soon as possible Make at least the minimum payment on every account The faster you catch up, the more you limit the damage. Ignoring missed payments only makes things worse. If Cash Flow Is Tight If you’re struggling to make payments, communication matters. Contact your lender and keep them informed—even if you can’t pay right away. Lenders are far more willing to work with you when you’re transparent. What hurts your credit most is silence . If lenders don’t hear from you after repeated missed payments, they may write the balance off as bad debt and send it to collections. Collections can significantly impact your credit and stay on your report for years. How This Affects Mortgage Qualification Repeated missed payments can make qualifying for a mortgage more difficult—but timing matters. Once you’re back to making regular, on-time payments: Your credit can improve over time The impact of past mistakes becomes less significant If you’re planning to buy a home in the next couple of years, addressing credit issues early gives you far more options later. Final Thoughts Missing a payment doesn’t mean you’re “bad with money,” and it doesn’t mean homeownership is off the table. What matters most is how quickly you respond and how consistent you are going forward .
