📌 From Tim — In Practice
In my experience, conventional underwriting is straightforward for clients with W-2 income and clean credit. The friction starts with self-employed borrowers (tax returns trigger income calculation gymnastics) and high-DTI buyers. For those clients, I often pivot to bank statement or DSCR.
🎯 TL;DR — Quick Answer
Conventional loan requirements: 620+ FICO minimum (best rates at 740+), 3-20% down payment, debt-to-income (DTI) ratio under 43-50%, 2 years of consistent income (W-2 or tax returns for self-employed). Tim Popp (NMLS #2039627) originates conventional loans across 37 states + DC.
Searching for a mortgage means dealing with mountains of paperwork and watching your credit score like a hawk. When you want competitive rates and flexible terms, conventional loans are usually where we start. These loans are backed by Fannie Mae and Freddie Mac, not a government agency like FHA or VA.
Whether you’re buying your first home or adding another property to your portfolio, you need to know what these loans actually require. I’m going to walk you through exactly what we look at when reviewing your application.
## What Are the Credit Score Requirements for Conventional Loans?
Your credit score is probably the biggest factor in your mortgage application. It determines whether you qualify and what you’ll pay for private mortgage insurance and your interest rate. For a conventional loan, the minimum credit score is usually 620.
But 620 is just the floor. Conventional loans use tiered pricing where your credit score directly affects your monthly payment. Borrowers with scores of 740 or higher get the best terms and lowest costs.
If your score is lower, you can still qualify, but you’ll face tighter requirements on your down payment or debt-to-income ratio. We use the middle score from the three major credit bureaus. If you’re applying with someone else, we use the lower person’s middle score.
Your recent credit history matters too. Beyond the three-digit number, we want to see on-time payments. If you’ve had a bankruptcy or foreclosure, you’ll need to wait before you can qualify for a conventional loan—typically four years for a Chapter 7 bankruptcy and seven years for a foreclosure.
## How Much Down Payment Do You Really Need?
Here’s a myth I hear constantly: you need 20% down to buy a home with a conventional loan. While 20% lets you avoid Private Mortgage Insurance (PMI), it’s not required. Many homebuyers qualify with as little as 3% down.
The 3% down payment programs are usually for first-time homebuyers or those meeting certain income limits. If you’ve owned a home in the last three years, the minimum is typically 5% for a primary residence. These low-down-payment options make conventional loans competitive with FHA loans and often provide better long-term value.
For investors, the rules change. If you’re buying a rental property, you’ll need more money in the deal. Down payments for investment properties typically start at 15% for a single-family home, though 20% to 25% is often needed for the best terms. You can learn more about these specifics in our guide on Conventional Loan for Investment Properties: Rules and Limits.
You also need to document where your down payment comes from. We look for “seasoned” funds—money that’s been in your bank account for at least 60 days. If you’re getting a gift from family, that works for a primary residence, but investment properties require your own funds.
## Understanding Your Debt-to-Income (DTI) Ratio
When we review your application, we’re not just looking at how much you make. We’re looking at how much of your income already goes to other debts. That’s your Debt-to-Income (DTI) ratio. We add up your proposed monthly mortgage payment (including taxes and insurance) plus your other monthly obligations like car loans, student loans, and credit card minimums.
For a conventional loan, the target DTI is 43% or lower. But if you have a strong credit score and solid cash reserves, you might qualify with a DTI as high as 50%. The automated underwriting systems from Fannie Mae and Freddie Mac look at your full profile to determine if the risk is acceptable.
If your DTI is too high for a standard conventional loan, there are other options. Some investors find that DSCR Loan Requirements: What Lenders Actually Look For work better because they focus on the property’s income instead of your personal DTI.
To keep your DTI healthy, avoid taking on new debt while you’re applying for a mortgage. Don’t lease a new car or finance a big furniture purchase. Even a small increase in your monthly obligations can change how much you’re eligible to borrow.
## What Income Documentation Will You Need to Provide?
Conventional loans are “full documentation” loans. We need to verify your ability to repay through official records. The requirements differ slightly based on how you earn money, but the goal is the same: showing a stable and predictable income.
If you’re a W-2 employee, the process is straightforward. We’ll ask for:
- Your most recent 30 days of paystubs.
- Your W-2 forms from the last two years.
- Your full personal tax returns from the last two years (sometimes).
- Verification of employment from your current employer.
For self-employed borrowers, we need more. We typically need two years of signed individual and business tax returns. We look at your net income—what’s left after business deductions—to determine your qualifying income. If your tax returns show a lot of write-offs that make your income look lower than it actually is, you might want to check out Bank Statement Loan Requirements: What You Need to Qualify as an alternative.
We also want to see income stability. We like to see that you’ve been in the same line of work for at least two years. If you recently changed jobs but stayed in the same industry, that’s usually fine. But a total career change or a move from W-2 to 1099 may require a longer history.
## Property Requirements and Appraisal Standards
A conventional loan isn’t just about you—it’s also about the property you’re buying. The home is collateral for the loan, so we need to confirm it’s worth the purchase price and is in safe, livable condition.
Once you’re under contract, we’ll order a professional appraisal. The appraiser looks at recent comparable sales in the area to determine fair market value. If the appraisal comes in lower than the purchase price, you’ll need to bridge the gap with additional cash or renegotiate with the seller.
Conventional appraisal standards are more flexible than FHA or VA standards. The home still needs to be structurally sound and free of major safety hazards (like peeling lead-based paint or exposed wiring), but conventional loans are often easier to use for homes that need cosmetic updates.
There are also limits on how much you can borrow, called conforming loan limits. These limits are set annually by the FHFA. If you’re looking at a home that exceeds these limits, you’ll need Jumbo financing, which has stricter requirements for credit scores and down payments. You can find more detail in What Is a Conventional Loan? The Complete Guide.
## The Role of Private Mortgage Insurance (PMI)
If you’re putting down less than 20%, you’ll probably need to pay for Private Mortgage Insurance (PMI). This is a policy that protects the lender if the loan goes into default. Nobody loves paying for insurance that doesn’t benefit them, but PMI is what lets you buy a home now instead of waiting years to save a massive down payment.
The cost of PMI on a conventional loan varies. It’s based on your credit score and your down payment percentage. Generally, the higher your score and the larger your down payment, the lower your PMI premium.
One major advantage of conventional loans over FHA loans is that PMI isn’t permanent. Once you reach 20% equity in your home—either by paying down the balance or through appreciation—you can request to have the PMI removed. That can save you hundreds of dollars every month for the rest of your loan term.
## Why Conventional Loans Are Often the Best Choice
For many of my clients, conventional loans offer the right balance of low costs and long-term flexibility. Sellers often view conventional offers as stronger than government-backed offers because the appraisal and inspection processes are smoother.
Conventional loans also offer variety in terms. While the 30-year fixed-rate mortgage is most popular, you can also get 15-year or 20-year terms if you want to pay off your home faster and save on interest. There are also Adjustable-Rate Mortgages (ARMs) that provide lower initial payments if you plan on moving or refinancing within a few years.
Every borrower’s situation is different, and while these are the standard guidelines, there are often ways to structure a loan to fit your specific financial picture. Whether you’re buying your first home or your tenth investment property, knowing these requirements gives you control over the process.

For Different Reader Perspectives
🏠 First-Time Buyer
Quick answer: Conventional loans usually need a 620+ credit score, but you don't need 20% down—many first-time buyers start with just 3-5%. Your credit score, down payment, and income all affect whether you qualify and what you'll pay each month.
From Tim: Most first-timers are surprised they can get started with way less than 20% down. Focus on your credit score first—it affects everything from approval to your monthly costs.
💼 Self-Employed
Quick answer: Conventional loans need 620+ credit, 3-20% down, and documented income—which can be tough for 1099 contractors. If tax write-offs tank your qualifying income, Bank Statement Loans may work better since they use deposits instead of tax returns.
From Tim: Self-employed? Conventional underwriting hates your tax returns. I use Bank Statement programs daily for contractors who show strong revenue but minimal taxable income—way more realistic for how you actually earn.
🎖️ Veteran
Quick answer: Conventional loans need 620+ credit and 3-20% down depending on use. If you have VA eligibility, you could get 0% down with no PMI and better terms. Conventional may work for investment properties where VA doesn't apply.
From Tim: If you've got VA eligibility, use it for your primary home—it beats conventional every time. Save conventional loans for rental properties or when you've already used your VA entitlement.
🏘️ Investor
Quick answer: Conventional loans need 15-25% down for rentals, 620+ credit, and tight DTI limits. They hit a 10-financed-property wall fast. If you're scaling or cash flow is tight, DSCR loans may fit your strategy better.
From Tim: Most investors outgrow conventional loans quickly. Once you hit 4-6 properties or need LLC vesting, we usually shift to DSCR products that qualify on the property's rent, not your personal income.
🏡 Refi / HELOC
Quick answer: Conventional loans aren't just for buying—they're a tool for tapping your equity. If you've built solid equity and have a 620+ credit score, you could access cash through a refinance or compare that to a HELOC, depending on your rate and goals.
From Tim: Most homeowners don't realize conventional cash-out refis can consolidate debt at better terms than HELOCs—but if your current rate is low, a HELOC might make more sense. Let's compare your options.
