Understanding How Debt Can Affect You When Applying for a Mortgage

Louisiana REALTORS® • January 23, 2026

Having debt doesn’t automatically disqualify you from buying a home. Plenty of buyers have student loans, car payments, or credit cards, and still close successfully.


What does derail transactions isn’t debt itself. It’s realizing halfway through the process that your buying power isn’t what you thought it was.


Understanding how debt affects your mortgage approval isn’t just helpful; it’s deal protection. Most buyers assume lenders only care about income and credit score. Debt is often treated like an afterthought.


But debt directly affects:

  • How much house you qualify for
  • What loan programs are available
  • How competitive your offer can be
  • Whether your deal survives underwriting


Here’s what buyers need to know before they fall in love with a house they can’t comfortably afford.


How Do Lenders Assess Debt When Applying for a Mortgage?

Your lender will look at your debt-to-income ratio (DTI) to determine your ability to manage monthly payments. DTI is the percentage of your gross monthly income that goes toward debt payments.


While buyers tend to focus on interest rates and purchase price, lenders are watching this number closely from the very first conversation through final underwriting.


What Do Lenders Consider to be Debt or Not?

When lenders talk about debt, they’re focused on monthly obligations. But not everything you pay monthly is considered debt for mortgage qualification purposes.


Debt includes:

  • Auto loans
  • Student loans (even deferred ones)
  • Credit cards (minimum monthly payments)
  • Personal loans
  • Lines of credit
  • Co-signed loans (yes, even if “someone else pays it”)


Commonly overlooked debts:

  • Buy-now-pay-later plans
  • Business debt that shows on personal credit


Everyday living expenses, such as utilities, groceries, phone bills, childcare, or regular savings contributions, aren’t considered debt by lenders and don’t factor into your mortgage approval.


However, just because these costs aren’t counted doesn’t mean they’re optional. From a real-world budgeting standpoint,

they matter a lot.


These expenses determine how comfortably you can live once the mortgage payment is added to the mix. Buyers who ignore them often find themselves feeling stretched, even if they technically qualify on paper.


How Debt Impacts How Much House You Can Comfortably Afford

Debt doesn’t just affect mortgage approval; it affects comfort.


Most buyers only hear “You’re approved up to X amount” and assume that number represents a comfortable, realistic budget. In reality, that figure often reflects the maximum a lender is willing to approve, not the amount that makes sense for your day-to-day life.


That maximum approval assumes nothing changes: no new debt, no rising living expenses, no unexpected costs. Even a small shift, such as a higher insurance quote or a slightly larger loan payment, can push the DTI ratio too high or to a level that is uncomfortable for buyers when all of your monthly obligations are factored in.


There’s a massive difference between being approved and being comfortably approved. The second one leads to better decisions.


Assess Debt Before You Start House Hunting

If you’re 3 - 6 months out from buying, review your debt to assess how it may affect your mortgage approval and get a better understanding of what you can comfortably afford.


Helpful steps to take include:

  • Talk to a lender early, preferably before browsing listings
  • Avoid new credit unless absolutely necessary
  • Ask whether paying down debt actually improves your scenario
  • Keep credit card balances low relative to limits
  • Be honest about co-signed or shared obligations


A coordinated plan between buyer, lender, and agent almost always leads to a smoother experience.


How a Real Estate Agent Can Help You Navigate Debt During the Homebuying Process

Working with a knowledgeable Real Estate Agent can help manage expectations and keep transactions intact.


That includes:

  • Working closely with lenders to align numbers and goals
  • Setting realistic price ranges before showings
  • Helping buyers understand trade-offs between price, debt, and comfort
  • Keeping deals on track when financial questions arise mid-transaction


When everyone is on the same page early, surprises are rare, and closings are far less stressful.


The smartest homebuyers aren’t the ones with zero debt. They’re the ones who understand their numbers before the first showing.



If you’re thinking about buying, start with clarity, not listings. The right agent and lender will help you build a plan that works in the real world, not just on paper.

2026 Legislative Session Scoop - Week 4 Recap

By Louisiana REALTORS® • April 3, 2026
This week, the Legislature remained in high gear, and several items relevant to Louisiana’s real estate market moved into focus. The biggest headline for our industry this week was HB 468 by Rep. Troy Hebert , our wholesaling/consumer-protection bill, was slated to be heard on the House floor, however was bumped due to floor congestion and out-of-order bills. It is now expected to be reset for next Tuesday. This bill remains one of the clearest “market integrity” efforts on the board with clearer rules for non-traditional transactions, stronger transparency and better consumer protections. We also continued substantive policy work behind the scenes. We are actively engaging with Rep. Carver on a vacant land disclosure bill he has authored, and we appreciate that he is welcoming our input and guidance as the language is refined. Our goal is straightforward: ensure any vacant land disclosure framework is practical, reduces confusion and avoids unintentionally shifting liability or enforcement burdens onto real estate professionals. In addition, we were pleased to deepen our relationships at the Capitol this week. We had the privilege of hosting a lunch for the Governor’s Office, enjoyed meeting Governor Landry’s team, and look forward to working with them in a constructive, solutions-oriented manner as the session continues. Finally, Rep. Hebert also filed an additional measure that aligns with our legislative agenda and speaks directly to transaction risk management: HB 1027 , which would limit liability for licensed real estate appraisers in situations involving smoke and carbon monoxide detector compliance. The current law already provides that real estate agents are not liable for a seller’s failure to comply with Louisiana’s detector requirements in one- or two-family dwellings. HB 1027 would extend that same liability protection to licensed appraisers by amending R.S. 40:1581(F). This is a clean, common-sense clarification that helps prevent appraisers from being pulled into compliance disputes that properly belong with the seller’s statutory obligations. Next week, committees are scheduled to hear multiple bills relevant to real estate, including measures involving construction and roofing standards (often tied to insurance and mitigation), property rights/expropriation, and property tax and adjudicated property issues that can influence housing supply and neighborhood reinvestment. We will stay closely engaged and will flag any bills or amendments that materially affect transactions, homeownership costs or private property rights.

2026 Legislative Session Scoop - Week 3 Recap

By Louisiana REALTORS® • March 27, 2026
Week three of the Regular Session kept real estate issues in the conversation, even as lawmakers continued to focus heavily on workforce, tax and insurance policy. On the property tax front, measures to reshape assessments and exemptions, including proposals for a new blight rehabilitation exemption and additional relief for seniors, remain parked in the House Ways and Means Committee as stakeholders work through fiscal and local government concerns. These bills matter because they will influence long-term carrying costs, redevelopment incentives and how tax burdens are shared across residential and commercial property. Homestead related legislation, including parish level authority to increase the exemption amount, is also in the queue, signaling that the broader structure of Louisiana’s homestead system is officially on the table, not just the dollar figure. For homeowners and buyers, this debate goes directly to affordability. For local governments, it raises revenue stability and service delivery questions. There also has been movement on several identical pieces of legislation that would instruct parish assessors to develop a process for homeowners to permanently register for the homestead exemption for the duration that they own and live on the property. We are actively tracking legislation that will directly shape how investor activity and non-traditional transactions are recognized and regulated in Louisiana’s real estate market. This includes HB 468 by Troy Hebert , a key component of the Louisiana REALTORS® legislative package that targets the wholesale of residential real estate, which was heard in the House Commerce Committee on Monday. The bill is currently positioned for a floor vote early next week. As drafted, HB 468 represents a major step in the right direction for consumer protection in Louisiana, advancing needed guardrails through potential disclosure, registration, and practice standards that could redefine how assignment contracts and “off-market” transactions intersect with licensed brokerage activity. In parallel, HB 292 by Delisha Boyd passed the House on final reading, 86-3, and is on its way to the Senate. Together, these measures represent a coordinated policy effort to bring greater structure and transparency to emerging transaction models, while preserving the integrity of the traditional brokerage framework. Finally, the broader policy backdrop remains important: the Governor continues to push income tax changes and cost of living relief, while business and industry groups are prioritizing insurance, workforce and energy — each a key driver of long run housing demand and investment. As these debates evolve, we’ll keep you updated on what moves, what stalls and what it all means for your clients, your pipeline and private property rights across Louisiana.
