Conventional loan requirements usually come down to five decisions: your credit profile, down payment, debt-to-income ratio, verified income and assets, and whether private mortgage insurance is required. A 620 score is a common starting point, but approval is never one number. Your loan structure, property type, reserves, and automated underwriting result matter just as much.

What conventional loan requirements really mean
A conventional mortgage is not insured by the Federal Housing Administration. That distinction can create a stronger fit for buyers with solid credit, stable income, and enough funds to make a meaningful down payment. It can also mean stricter underwriting than FHA financing, particularly when credit is limited, debt is high, or income has recently changed.
Most conventional programs are built around agency underwriting standards, but individual wholesale programs can vary. Some borrowers qualify with 3% down. Others need 5%, 10%, or more because of their credit score, property type, occupancy, loan amount, or automated underwriting findings. A primary residence normally receives better terms than a second home or investment property.
Credit, income, debt, and assets
Credit score and payment history
A 620 FICO score is widely used as a conventional baseline, although a higher score generally provides more options and lower pricing. Scores in the 680 to 740 range often produce a noticeable improvement in rate and PMI pricing. A score above 760 may provide the strongest available pricing, assuming the rest of the file supports it.
Late payments, collections, charge-offs, recent inquiries, and high revolving-card balances can affect approval. The score itself is only part of the analysis. Underwriters also review whether obligations are current, how recently a problem occurred, and whether the borrower has re-established a reliable payment pattern.
Income and debt-to-income ratio
Conventional underwriting verifies that income is stable, documented, and likely to continue. Pay stubs, W-2s, tax returns, bank statements, and business records may all be required depending on how you earn income. Self-employed borrowers should expect a closer review because qualifying income is based on documented net income, not gross revenue.
Debt-to-income ratio compares your monthly debt obligations with gross monthly income. Many conventional files work best at 43% or below, though an automated approval can sometimes allow a higher ratio when credit, reserves, and other compensating factors are strong. The payment used in that calculation includes principal, interest, property taxes, homeowners insurance, HOA dues when applicable, and PMI.
Down payment, reserves, and source of funds
First-time buyers may have 3% down options on an eligible primary residence. Buyers with stronger profiles often choose 5% down because it can expand program choices and improve PMI pricing. Gift funds may be acceptable on many primary-residence transactions, but every deposit must be sourced. Large unexplained deposits can delay underwriting.
Cash reserves are not required for every conventional purchase, but they can matter. Reserves are funds remaining after closing, measured in months of the proposed housing payment. They are especially helpful for higher debt ratios, multi-unit properties, second homes, or borrowers whose income is variable.
Conventional down payment and PMI: real payment math
Private mortgage insurance, or PMI, is generally required when the down payment is below 20%. PMI is not a flat national charge. It is priced using credit score, down payment, debt ratio, occupancy, and coverage level. That means two buyers purchasing the same home can receive different PMI quotes.
Here is a fully worked example using a $400,000 primary-residence purchase. Assume a 5% down payment, a 6.50% fixed interest rate, a 30-year term, annual property taxes of $4,800, annual homeowners insurance of $1,800, and estimated PMI of 0.55% annually. This is an illustration, not a rate quote.
- Purchase price: $400,000
- Down payment: $400,000 × 5% = $20,000
- Loan amount: $400,000 – $20,000 = $380,000
- Principal and interest: approximately $2,402 per month
- Property taxes: $4,800 ÷ 12 = $400 per month
- Homeowners insurance: $1,800 ÷ 12 = $150 per month
- PMI: $380,000 × 0.55% ÷ 12 = $174.17 per month
- Estimated total housing payment: $2,402 + $400 + $150 + $174.17 = $3,126.17 per month
PMI may be cancellable once the loan reaches the required equity threshold and payment history conditions are met. That differs from FHA mortgage insurance, which follows separate rules based on the loan term, loan-to-value ratio, and initial down payment.
FHA versus conventional requirements
For a buyer with strong credit and 5% to 20% down, conventional financing may offer lower monthly mortgage insurance costs or no PMI at all. For a buyer with a 580 to 619 score, higher debt ratio, or a 3.5% down payment plan, FHA may be the more practical approval path. The better choice depends on total payment, cash to close, future refinance plans, and underwriting strength.
| Factor | Conventional | FHA | Why it matters |
|---|---|---|---|
| Typical credit starting point | 620, program dependent | 580 for 3.5% down | FHA can be more forgiving with lower scores. |
| Minimum down payment | 3% for eligible buyers | 3.5% with 580+ credit | Both can preserve cash, but underwriting differs. |
| Mortgage insurance | PMI usually below 20% down | Upfront and annual MIP | Compare monthly cost and future removal options. |
| Debt ratio flexibility | Often strongest near 43% | Can allow more flexibility | Automated findings and compensating factors control. |
Guideline comparison verified as of July 31, 2026. Conventional eligibility and pricing are program-specific; FHA requirements may also vary based on automated underwriting and documented compensating factors.
Why the pre-approval method matters
A pre-approval should give you useful numbers without creating unnecessary anxiety around your credit. The NoTouch Credit Pull process begins with a soft pull credit review, allowing a realistic discussion of score range, debt, payment targets, and likely program paths. A soft credit pull does not create a hard inquiry on your consumer report.
For buyers still comparing homes or deciding between FHA and conventional, a soft pull pre-approval can be a practical first step. NoTouch Credit Pull is designed to provide that early direction with no hard credit inquiry. You may also hear this described as a soft credit check or soft pull credit review. The terminology varies, but the goal is the same: evaluate options before a full application decision is necessary.
As an independent broker, I can compare programs across 500+ wholesale sources rather than limit the review to one retail shelf. That does not guarantee approval or a particular rate. It does create more room to match a borrower’s credit, income, assets, and property goals with an appropriate conventional or FHA path.
Frequently Asked Questions
What credit score is needed for a conventional loan?
A 620 score is a common conventional starting point, but it is not a universal approval guarantee. Higher scores can improve pricing, reduce PMI costs, and allow more flexibility with debt ratios. The full credit report, payment history, loan amount, occupancy, and automated underwriting findings determine the actual result.
Can I get a conventional loan with 3% down?
Yes, eligible buyers may qualify for a 3% down conventional primary-residence program. Availability depends on income, first-time buyer status in some programs, credit, and property eligibility. A 3% down option can work well, but compare its PMI cost against 5% down before choosing the lowest cash investment.
Is PMI required on every conventional mortgage?
No. PMI is typically required when you put less than 20% down, although some loan structures have different rules. PMI pricing depends heavily on credit and down payment. Unlike FHA mortgage insurance, conventional PMI may be removed when equity and payment-history requirements are satisfied.
What debt-to-income ratio is acceptable for conventional financing?
Many conventional approvals are strongest at a debt-to-income ratio of 43% or less. Some automated underwriting approvals allow a higher ratio when the borrower has strong credit, meaningful reserves, a larger down payment, or stable documented income. The proposed full housing payment is included in the calculation.
Are gift funds allowed for a conventional down payment?
Gift funds are often allowed for a primary-residence conventional purchase, subject to program rules and documentation. The donor, amount, transfer trail, and borrower contribution may need to be verified. Funds must be properly sourced before closing, so do not move money between accounts without discussing it first.
Is conventional better than FHA for a first-time buyer?
It depends on credit, cash available, debt ratio, and the projected monthly payment. Conventional may be less expensive for a buyer with stronger credit and enough down payment to reduce PMI. FHA may be more practical for buyers who need 3.5% down or more flexible credit treatment.
Does a soft pull pre-approval affect my credit score?
A soft pull pre-approval generally does not create a hard inquiry or lower your consumer credit score. It provides an early view of credit, debts, and possible financing paths. A full application may later require additional verification and a hard inquiry, depending on the program and transaction stage.
Can a self-employed buyer qualify for a conventional loan?
Yes, self-employed buyers can qualify when income is stable and supported by documentation. Underwriting usually reviews personal and business tax returns, bank statements, year-to-date results, and any declining-income trends. Gross business revenue is not the qualifying figure. Documented net income and its consistency matter most.
Conventional financing rewards preparation. Before you decide that a 3% down loan, 5% down loan, or FHA option is right for you, compare the full payment, cash required, and underwriting path side by side. That is how you move forward with confidence instead of guessing.
