The requirements for a conventional loan depend on your credit history, documented income, existing debts, available funds and the property you want to finance. There is no single credit-score or down-payment rule that applies to every borrower.

Key Takeaways

  1. Credit requirements depend on underwriting. Fannie Mae DU has no minimum score; manual loans and lender overlays can have thresholds.
  2. DTI limits vary. Fannie Mae manual limits generally start at 36%, with qualified exceptions to 45%; DU allows up to 50%.
  3. 3% down is available on selected programs. Other purchases require more; PMI generally applies below 20% down.
  4. Income, funds and property must qualify. Document available cash and confirm the valuation and property-review requirements.

This guide focuses on qualifying for a conforming conventional mortgage, with current agency rules and the questions to ask before applying. For available Florida financing options and a scenario review, visit our conventional mortgages program page.

Bennett Capital Partners Mortgage Brokers helps Florida borrowers compare lender requirements. An agency guideline sets the underlying eligibility standard; a lender may impose a stricter requirement, often called an overlay. Meeting a published minimum does not guarantee loan approval.

Requirements for a Conventional Loan

To qualify for a conventional loan, you need acceptable credit, sufficient qualifying income, a permitted debt-to-income ratio, documented funds and an eligible property. Selected primary-residence programs allow 3% down; other transactions require more.

Fannie Mae and Freddie Mac have separate underwriting guides. The detailed credit and DTI examples below use Fannie Mae rules and should not be assumed to apply identically to Freddie Mac, jumbo loans or every lender.

Credit Score Requirements: Automated vs. Manual Underwriting

A minimum credit score of 620 is not a universal conventional loan requirement. Under current Fannie Mae guidance, Desktop Underwriter (DU) does not impose a minimum score. DU evaluates the credit report and the overall risk of the application.

For manually underwritten Fannie Mae loans, the general minimum is 620 for fixed-rate loans and 640 for adjustable-rate mortgages, subject to the Eligibility Matrix and specific exceptions. Mortgage lenders and mortgage insurers may apply additional standards.

Ask which underwriting system will assess your file and whether the quoted score threshold is an agency rule or a lender overlay. For agency-specific distinctions, review Fannie Mae DU and manual underwriting. A higher credit score can affect pricing, but payment history, recent derogatory events, debts and available assets also matter.

Debt-to-Income Ratio Requirements

Debt-to-income ratio (DTI) compares your qualifying monthly debt payments with the monthly income the lender can use. It includes the proposed housing payment, property taxes, insurance, applicable mortgage insurance and association dues, plus other counted obligations.

Fannie Mae generally limits manually underwritten loans to 36% DTI, allowing up to 45% when the credit-score and reserve requirements are met. Its DU maximum is 50%. These are agency limits, not assurances of approval; transaction exceptions and lender overlays can be more restrictive.

Hypothetical example: $2,400 in proposed monthly housing costs plus $600 in other counted debts equals $3,000. With $7,500 in qualifying gross monthly income, DTI is $3,000 ÷ $7,500 = 40%.

That 40% result falls below the DU ceiling, but the application still needs an acceptable underwriting recommendation and must satisfy the other loan conditions. Your personal spending budget may be tighter than the lender’s qualifying calculation.

Use our debt-to-income ratio guide for the broader calculation. Here, the key question is which DTI limit applies to your conventional loan file.

Minimum Down Payment and Private Mortgage Insurance

You do not have to put 20% down to buy a home with conventional financing. Certain programs permit 3% down, but this option has borrower, occupancy and property restrictions. Many other primary-residence purchases start at 5%; second homes, investment properties and some other transactions require more.

Fannie Mae’s standard 97% loan-to-value purchase option is for an eligible one-unit principal residence, uses a fixed-rate loan and DU, and requires at least one first-time homebuyer. HomeReady has separate rules. Confirm the specific purchase-transaction requirements before relying on 3% down.

Private mortgage insurance (PMI) is generally required when a conventional purchase has less than 20% down. It protects the lender, not the borrower. At 20% down, borrower-paid PMI is generally unnecessary. Compare the payment, insurance cost and cash left after closing before choosing a larger down payment.

Property Eligibility and Appraisal Requirements

The property must meet the selected loan program’s eligibility and condition standards. Conventional appraisals assess market value and report relevant condition issues. An appraisal is different from a buyer’s home inspection and should not replace your inspection decision.

An appraisal is not required for every transaction. Fannie Mae may offer value acceptance on eligible DU casefiles, subject to its restrictions and the lender’s decision. Read our appraisal waiver guide for a fuller explanation.

For a Florida condo, the unit and the condominium project may need separate reviews. Borrower approval does not establish project eligibility. Our Florida condo buyer checklist explains which association records to request before making an offer.

Conforming Loan Limits in 2026

Conventional and conforming are different labels. A conventional mortgage is outside government loan programs such as FHA, VA and USDA. A conforming loan also meets the applicable Fannie Mae or Freddie Mac requirements, including its loan-size limit.

For 2026, the FHFA baseline conforming loan limit is $832,750 for a one-unit property in most U.S. counties. High-cost areas and properties with more units have different limits.

Check the property’s actual county, legal unit count and applicable year using FHFA’s loan-limit resources. The limit applies to the loan amount, not the home’s purchase price.

A loan above the applicable conforming limit may need jumbo financing, which is still conventional but follows different investor and lender requirements.

Our jumbo versus conventional loan comparison addresses that separate decision. This article’s agency eligibility figures should not be used as a jumbo loan approval checklist.

Income and Employment Requirements

There is no single salary that qualifies everyone for a conventional home loan. The lender must establish stable, documented income that is reasonably expected to continue, then compare it with the qualifying payment and debts. A household’s gross revenue or total deposits may not equal its qualifying income.

History and documentation depend on the income source. Salary, commission, bonus, rental and self-employment income have different rules. A job change is not automatically disqualifying, but the lender must evaluate the new earnings and required evidence under Fannie Mae’s income guidance.

Cash Reserves and the Funds Left After Closing

Reserves are eligible assets available after closing, measured in months of the qualifying housing payment. They are separate from the money spent on the down payment and closing costs. Fannie Mae does not set a blanket minimum reserve requirement for every one-unit primary-residence DU transaction, but DU can require reserves based on risk.

Second homes, investment properties, multi-unit homes and other scenarios can have different requirements. Compare investment-property financing requirements if the home will be a rental. Ask the lender to state the amount and eligible asset sources for your file using the applicable reserve rules.

When Conventional Loan Requirements Do Not Fit

An unsuccessful conventional review does not establish whether another program will work. Our guide to non-conventional loan alternatives explains the main program categories. Compare the reason for the issue, such as credit, qualifying income, funds or property eligibility, with the actual requirements of the alternative.

VA loans

VA loans may fit eligible veterans, service members and surviving spouses with a Certificate of Eligibility who meet lender requirements and intend to occupy the home.

Eligible VA purchases can require no down payment and do not require PMI. A down payment can still be necessary depending on the price, appraised value and available entitlement.

VA has its own property and appraisal standards, and a funding fee may apply unless an exemption is available. Review the VA purchase-loan guidance rather than assuming every borrower qualifies.

FHA loans

An FHA loan uses a different credit and underwriting framework and may be worth reviewing when conventional financing does not fit. It is not limited to first-time home buyers.

FHA requires mortgage insurance, so compare total costs rather than assuming that a lower advertised rate makes it less expensive.

Use our FHA eligibility guide for that alternative. Keep the eligibility review specific to the borrower and property.

USDA loans

USDA loans may offer 100% financing for eligible primary residences in qualifying rural areas, subject to household-income and other program requirements.

Check the exact property address and household eligibility. An area’s suburban appearance does not by itself establish USDA eligibility.

The USDA Guaranteed Loan Program has its own fees, income limits and property rules. It is not a substitute for reviewing the full application.

Benefits of Conventional Loans

Conventional financing can work across several occupancy types and repayment structures. The available terms depend on the selected product and your qualifications.

These benefits have trade-offs: low-down-payment loans generally include PMI, property use can change required equity and reserves, and stronger credit does not remove documentation requirements.

The following features help frame the decision without promising a lower rate, easier approval or a larger loan than every government-backed alternative.

FeatureWhat to Confirm
Occupancy options Eligible programs can finance primary residences, second homes or investment properties. Requirements differ by use.
Repayment terms Term availability depends on the product and lender; compare the resulting payment and repayment period.
Pricing Credit, equity, product and market conditions affect pricing. Conventional is not always the lowest-cost choice.
Mortgage insurance Borrower-paid PMI is generally unnecessary with 20% down on a purchase. Lower down payments generally require coverage.
Loan size Conforming limits depend on county, unit count and year. Larger conventional loans can require jumbo financing.
Underwriting route Automated and manual underwriting apply different rules. Lender overlays can be stricter than agency standards.
Rate structure Both fixed-rate and adjustable-rate conventional products are available, with different payment risks.
Refinancing A refinance must meet its own equity, income, credit and cost requirements. Savings are not guaranteed.

Compare the Full Cost, Not Just the Interest Rate

A conventional loan does not automatically have a lower interest rate than FHA, VA or USDA financing. Compare offers made on the same date with the same loan amount, down payment, term and rate-lock assumptions. Use our mortgage calculator to compare estimates using your own figures.

Review the interest rate, annual percentage rate (APR), discount points, lender fees, mortgage insurance and cash to close. A lower rate purchased with points can require more upfront money.

Use the Loan Estimate to compare mortgage offers consistently. The lender’s qualifying payment and your full household budget answer different questions.

Flexible terms

Fixed-rate and adjustable-rate conventional loan options can suit different plans. A fixed rate provides interest-rate stability; an adjustable rate can change after its initial period.

A shorter repayment term generally raises the monthly principal-and-interest payment while reducing the repayment period. Evaluate the payment you can sustain, not only the total interest estimate.

For a general explanation and the application-to-closing sequence, use our step-by-step conventional mortgage guide. This page concentrates on the requirements your file must satisfy.

No mortgage insurance with 20% down payment

With 20% down on a conventional purchase, borrower-paid PMI is generally not required. With less down, ask how mortgage insurance is paid and whether any lender-paid arrangement affects the interest rate.

PMI cancellation has separate conditions; it is not always automatic when your estimated equity reaches 20%. The CFPB’s PMI explanation outlines the cost and cancellation considerations.

How to Prepare to Qualify for a Conventional Loan

Before applying, identify the specific obstacle and collect records that let the lender evaluate it. A practical preparation plan is more useful than pursuing one score or down-payment number in isolation.

Improve your credit score

Review your credit reports for errors and make payments on time. Mortgage credit scores may differ from the score displayed by a consumer app.

Ask whether the selected lender has a minimum score overlay and which credit issues need resolution. Do not assume DU’s lack of a minimum score means poor credit history will be accepted.

Discuss planned credit changes before closing. New accounts, increased balances or disputed information can affect underwriting and require another review.

Lower your debt-to-income ratio

List the proposed housing expense and every recurring obligation the lender needs to count. For variable earnings, use the lender’s qualifying-income calculation rather than your best recent month.

Ask whether paying off a debt would improve the qualifying ratio and what documentation is needed. Using cash to reduce debt can leave less available for the down payment, closing costs or reserves.

Disclose changes in income and liabilities before closing. A conditional approval can change when the application’s financial information changes.

Plan the Down Payment, Closing Costs and Reserves

The down payment is only one part of the funds needed. Closing costs, prepaid expenses and escrow deposits can require additional cash; reserves, when required, must remain available after closing.

Hypothetical cash illustration: on a $400,000 purchase, 3% down is $12,000, 5% is $20,000 and 20% is $80,000. These amounts exclude closing costs and do not establish eligibility for any of those down-payment options.

Document the source of funds before moving money. Eligible personal gifts have donor and documentation rules; gifts are not permitted for Fannie Mae investment-property transactions.

Research and compare lenders and rates

Ask each mortgage lender to identify the product, underwriting method, overlays and unresolved conditions. A published guideline is different from a lender’s commitment to approve your file.

Compare the same loan structure using written estimates. Include PMI and cash to close so a lower headline payment does not conceal higher fees or a different term.

Bennett Capital Partners is a mortgage broker, not the lending institution making the final underwriting decision. Our role is to help Florida borrowers compare applicable lender options and documentation requirements.

Gather Income, Asset and Property Documentation

Income records depend on how you earn and the underwriting findings. Employed borrowers commonly provide recent pay statements and W-2s; self-employed or variable-income borrowers may need tax returns and additional business records. Electronic validation can change the documentation required.

Provide account statements, identification, information about existing debts and, when available, the purchase contract. Explain material deposits and gifts. Follow the lender’s actual checklist instead of assuming every borrower needs the same two years of every document.

Complete records allow the lender to confirm your qualifying income and available funds. They do not replace property review, underwriting approval or the final conditions required to close.

Confirm Your Eligibility Before Choosing a Loan

Conventional loan requirements work together. Confirm the underwriting route, qualifying income, counted debts, available funds and property eligibility before selecting a down payment or comparing rates.

Frequently Asked Questions

What are the requirements for a conventional loan?

You need acceptable credit, documented qualifying income, a permitted DTI ratio, sufficient funds and an eligible property. Agency rules, automated underwriting findings, mortgage insurance and lender overlays all affect the result. There is no single minimum that guarantees approval.

Can I buy a house with less than 20% down payment using a conventional mortgage?

Yes. Selected conventional purchase programs permit 3% down, while others require 5% or more depending on the transaction. PMI is generally required below 20% down. Your closing costs and any required reserves are additional considerations.

How does my credit score affect my chances of getting approved for this type of mortgage?

The lender reviews your credit history and underwriting results, and your credit score can affect pricing and mortgage insurance. Fannie Mae DU has no minimum score, but manual underwriting and individual lenders can have minimums. A higher score alone does not guarantee approval.

Is there any difference between non-conforming loans and conventional conforming loans?

Yes. Conforming loans meet the applicable Fannie Mae or Freddie Mac standards, including loan limits. Nonconforming loans, including jumbo mortgages, fall outside those standards. Both categories can be conventional, meaning they are outside FHA, VA and USDA loan programs.

Are there specific mortgages available just for first-time home buyers?

Yes. Some low-down-payment options require a first-time homebuyer, while others have different eligibility rules. Review our HomeReady program guide and HomeReady income-limit guide for the detailed program requirements.

Can anyone apply for a conventional mortgage?

A borrower must meet the selected program’s eligibility rules and the lender’s underwriting standards. Income, credit, debts, funds, occupancy and the property all need review. A preapproval remains subject to its stated conditions and final underwriting.
