Key takeaways
- Conventional describes who does not back the loan: no FHA, VA, or USDA insurance or guaranty behind it.
- Conforming is a subset of conventional that also meets Fannie Mae and Freddie Mac requirements, including the applicable FHFA loan-size limit.
- The 2026 baseline one-unit conforming limit is $832,750, rising to $1,249,125 in designated high-cost areas.
- Twenty percent down is not a requirement. It is the level where private mortgage insurance generally is not required at origination.
- Conventional loans can be fixed or adjustable, 10 to 30 years, for primary homes, second homes, or investment property — the label says nothing about structure.
- Whether conventional beats FHA or VA depends on credit profile, down payment, property, and how long you keep the loan — not on a general ranking.
The definition, precisely
Mortgages are usually sorted by who stands behind them. FHA loans carry insurance from the Federal Housing Administration. VA loans carry a guaranty from the Department of Veterans Affairs. USDA loans carry a USDA guarantee. A conventional loan carries none of those — it is originated and held or sold entirely in the private market.
That single distinction drives most of the practical differences people notice: how mortgage insurance is priced and removed, which upfront fees exist, how property and occupancy rules are written, and which loan-size limits apply.
Conforming, high-balance, and jumbo
Within conventional lending, loan size is the first fork in the road. The same dollar amount can be treated three different ways depending on the county and the number of units in the property.
| Classification | What it means | Where it applies |
|---|---|---|
| Conforming | At or below the standard FHFA limit and meeting Fannie Mae or Freddie Mac requirements | Most U.S. counties |
| High-balance conforming | Above the standard limit but at or below the county's higher limit | Designated high-cost counties |
| Non-conforming (jumbo) | Above the applicable limit for that county and unit count | Any county, once the loan size passes the limit |
All three are conventional. Only the first two are conforming. Jumbo loans are underwritten to the individual lender's or investor's guidelines, which is why their credit, reserve, and documentation expectations often differ from conforming loans.
You can check where a specific loan amount falls with the jumbo vs conforming classifier, which uses the official 2026 county table.
How 2026 loan limits work
The Federal Housing Finance Agency publishes conforming loan limits each year for every county and county equivalent, at one, two, three, and four units. The baseline rises or falls with FHFA's house-price index, and high-cost areas receive a higher limit tied to local median home values, subject to a national ceiling.
| Tier | One-unit limit | Coverage |
|---|---|---|
| Standard baseline | $832,750 | 3,075 county records |
| High-cost areas (up to the ceiling) | up to $1,249,125 | 123 county records |
| Alaska, Hawaii, Guam, U.S. Virgin Islands | $1,249,125 statutory baseline | 37 county records |

What underwriting looks at
Conventional underwriting weighs a handful of factors together rather than applying a single cutoff. No one factor decides the outcome, and strength in one area can offset a weaker one — within limits set by the program.
| Factor | Why it matters | What tends to help |
|---|---|---|
| Credit profile | Influences eligibility and pricing, including mortgage insurance | Longer history, low utilization, no recent derogatory events |
| Debt-to-income ratio | Measures capacity to carry the new payment | Paying down installment debt with few payments remaining |
| Down payment / LTV | Drives whether mortgage insurance applies and how it is priced | Reaching a lower LTV tier, when it does not exhaust reserves |
| Reserves | Cash remaining after closing, measured in months of payments | Documented, seasoned funds in an eligible account |
| Occupancy | Primary, second home, and investment carry different expectations | Accurate occupancy intent stated up front |
| Property type | Condos, multi-unit, and manufactured homes have specific rules | Reviewing project or property eligibility early |
The qualification factors guide goes deeper on each, and the DTI calculator lets you model the ratio with your own numbers.
Mortgage insurance on a conventional loan
When a conventional loan starts above 80% loan-to-value, private mortgage insurance generally applies. PMI protects the lender, not the borrower — but it is what makes a low-down-payment conventional loan possible at all, and it is not permanent.
Two mechanisms end PMI on most conventional loans: a borrower-initiated request once the loan reaches the applicable equity threshold, and automatic termination on the amortization schedule. That contrasts with FHA mortgage insurance, which on many current FHA loans lasts the life of the loan unless the borrower refinances.
Conventional vs government programs
No program is universally better. The comparison depends on your credit profile, available down payment, the property, and how long you expect to keep the loan.
| Program | Backed by | Frequently considered when |
|---|---|---|
| Conventional | No government agency | Credit profile is solid and removable mortgage insurance matters over a long hold |
| FHA | Federal Housing Administration insurance | Credit or DTI profile makes conventional pricing difficult |
| VA | Department of Veterans Affairs guaranty | Borrower is an eligible service member, veteran, or surviving spouse |
| USDA | USDA guarantee | Property is in an eligible rural area and income limits are met |

Who it tends to fit
Where it tends to help
- Borrowers whose mortgage insurance can be removed within their expected holding period.
- Buyers of second homes or investment property, where FHA and VA generally are not options.
- Borrowers with a strong credit profile who want pricing to reflect it.
- Anyone who wants to avoid an upfront government insurance premium financed into the loan.
Trade-offs to weigh
- Underwriting expectations can be less forgiving than FHA on credit and DTI.
- Mortgage insurance pricing is sensitive to credit profile and LTV together.
- High-balance and jumbo tiers may bring stricter reserve and documentation expectations.
- Program eligibility and pricing vary by lender; two quotes are not automatically comparable.
Worked examples
Myths worth retiring
- Myth: You need 20% down for a conventional loan.
- Twenty percent is the LTV threshold at which PMI generally is not required at origination, not a minimum down payment.
- Myth: Conventional and conforming mean the same thing.
- Conforming is a subset of conventional. A jumbo loan is conventional but not conforming.
- Myth: Conventional PMI never goes away.
- That description fits many current FHA loans. Conventional mortgage insurance generally terminates by request or automatically on the amortization schedule.
- Myth: Conventional loans are always cheaper.
- Cost depends on credit profile, LTV, mortgage insurance pricing, and holding period. FHA is sometimes the stronger structure.
- Myth: Jumbo means luxury.
- Jumbo is purely a loan-size classification relative to the county limit. In some counties a modest home can require a jumbo loan.
Common mistakes
- Assuming a program is off the table because of a 20% down payment myth.
- Comparing programs on monthly payment alone, ignoring mortgage insurance removal and holding period.
- Draining cash reserves to reach a specific LTV tier, then having nothing left after closing.
- Treating the national baseline as your limit without checking the county and unit count.
- Shopping quotes with different assumptions about points, escrows, and mortgage insurance structure.
- Waiting until underwriting to raise condo project, occupancy, or property-type questions.

Frequently asked questions
Is a conventional loan the same as a conforming loan?
No. Conventional means not insured or guaranteed by a government agency. Conforming is a narrower subset: a conventional loan that also meets Fannie Mae and Freddie Mac requirements, including the applicable FHFA loan-size limit. Every conforming loan is conventional; not every conventional loan is conforming.
Do I need 20% down for a conventional loan?
No. Twenty percent is the level at which private mortgage insurance generally is not required at origination, not a minimum. Conventional programs exist with lower down payments; those typically involve mortgage insurance until the loan reaches the applicable equity threshold.
Does a conventional loan always have a fixed rate?
No. Conventional refers to who backs the loan, not how the rate behaves. Conventional loans are available as fixed-rate and adjustable-rate structures across multiple terms.
Can I use a conventional loan for a second home or rental?
Conventional financing is commonly available for primary residences, second homes, and investment properties, but qualification expectations, down payment, reserves, and pricing differ by occupancy type. Confirm specifics with a licensed loan officer.
What happens if my loan is larger than my county limit?
A loan above the applicable FHFA limit for the county and unit count is generally classified as non-conforming, often called jumbo. It is still conventional, but it is underwritten to the individual lender or investor's guidelines rather than Fannie Mae or Freddie Mac conforming requirements.
