4.2 Loan Programs: Conventional, Conforming vs. Jumbo, FHA, VA & USDA

Conventional Financing: Conforming vs. Non-Conforming Loans

A conventional mortgage is any residential loan that is not directly insured or guaranteed by an agency of the federal government (such as the FHA, VA, or USDA). Conventional loans represent the largest segment of the residential mortgage marketplace.

Conforming Loans

A conforming loan adheres to the underwriting guidelines, credit standards, and loan limit ceilings established annually by the Federal Housing Finance Agency (FHFA) for purchase by government-sponsored enterprises (GSEs)—specifically Fannie Mae (Federal National Mortgage Association) and Freddie Mac (Federal Home Loan Mortgage Corporation).

Key characteristics of conforming loans include:

• Uniform Documentation: Borrowers submit standard application forms (Fannie Mae Form 1003 / Freddie Mac Form 65, Uniform Residential Loan Application) and standard appraisals (Uniform Residential Appraisal Report, Form 1004).
• Underwriting Standards: Underwritten through automated underwriting systems (AUS)—Desktop Underwriter (DU) for Fannie Mae or Loan Product Advisor (LPA) for Freddie Mac. Benchmark parameters require a minimum credit score (typically 620), verified employment, and standard debt-to-income (DTI) ratios, conventionally 28% front-end (housing expenses) and 36% back-end (total monthly debt), though AUS approvals can extend up to 45% or 50% with strong compensating factors.
• Conforming Loan Limits: Maximum mortgage amounts set by the FHFA. Because northern and central New Jersey counties (e.g., Bergen, Essex, Hudson, Morris) have median home prices far exceeding national averages, many New Jersey jurisdictions are designated as high-cost areas, granting significantly elevated conforming loan limits compared to baseline counties.

Non-Conforming and Jumbo Loans

A loan is non-conforming if it fails to satisfy GSE purchase criteria. The most common category is a jumbo loan, where the loan amount exceeds the FHFA conforming limit for that county.

• Portfolio Retention or Private Securitization: Because Fannie Mae and Freddie Mac cannot buy jumbo loans, lenders either hold them in their own asset portfolios or securitize them through private non-agency investment trusts.
• Underwriting Rigor: Jumbo loans generally require higher credit scores (often 700+), larger down payments (10% to 20%), lower debt-to-income ratios (capped at 43%), and substantial post-closing cash reserves (typically 6 to 12 months of principal, interest, taxes, and insurance—PITI).

Private Mortgage Insurance (PMI)

When a borrower obtains a conventional loan with a down payment of less than 20%—meaning the Loan-to-Value (LTV) ratio exceeds 80%—the lender almost universally requires Private Mortgage Insurance (PMI). PMI protects the lender against financial loss on the top 20% to 25% of the loan amount in the event of borrower default and subsequent foreclosure deficiency.

Homeowners Protection Act of 1998 (HPA)

The Homeowners Protection Act (12 U.S.C. § 4901 et seq.) establishes clear federal rules regarding the cancellation and termination of borrower-paid PMI on residential, single-family, primary residences:

+---------------------------------------------------------------------------------------------------------+

FHA-Insured Loans (HUD Title II, Section 203b)

The Federal Housing Administration (FHA), an agency within the Department of Housing and Urban Development (HUD), does not originate mortgage loans. Instead, it insures approved private lenders against losses resulting from borrower default under the Section 203(b) program for 1-to-4 family residential properties.

• Down Payment Requirements: A minimum down payment of 3.5% is required for borrowers with a credit score of 580 or higher. Borrowers with scores between 500 and 579 require a 10% down payment. Down payment funds can be 100% gifted from acceptable sources (relatives, employers, non-profit assistance programs) with a verified gift letter.
• Mortgage Insurance Premiums (MIP): FHA requires two distinct insurance premiums:
  1. Upfront Mortgage Insurance Premium (UFMIP): A one-time premium equal to 1.75% of the base loan amount, which can be paid in cash at closing or financed into the total loan amount.
  2. Annual Mortgage Insurance Premium (Annual MIP): An ongoing premium calculated as an annual percentage (typically 0.55% for 30-year loans with 3.5% down) divided into 12 monthly installments added to the monthly mortgage payment. For loans originated with an LTV greater than 90%, the annual MIP remains for the entire loan term and cannot be cancelled.
• Qualifying Ratios and Limits: Standard debt ratios are 31% (housing) and 43% (total debt). FHA establishes maximum loan limits by county based on local median sales prices. Properties must satisfy HUD's strict Minimum Property Standards (MPS) regarding safety, soundness, and structural integrity.

VA-Guaranteed Loans

Administered by the Department of Veterans Affairs, the VA home loan program provides long-term financing to eligible American veterans, active-duty service members, and qualifying surviving spouses.

• 100% Financing: Qualified veterans can purchase a primary home with zero down payment (100% loan-to-value).
• No Monthly Mortgage Insurance: The VA charges no monthly mortgage insurance premium, substantially lowering the veteran's monthly payment relative to FHA or conventional financing.
• Eligibility and Entitlement: The veteran must obtain a Certificate of Eligibility (COE) based on qualifying service documented on a DD-214 (military discharge form) or Statement of Service. The basic entitlement guarantees up to 25% of the loan amount to the lender against loss.
• VA Funding Fee: To offset the cost of default claims, the VA assesses a one-time Funding Fee (ranging from 1.25% to 3.3% for first-time or subsequent use), which can be financed. Veterans receiving VA disability compensation for a service-connected disability are completely exempt from the funding fee.
• Appraisal and Notice of Value (NOV): A VA-assigned fee appraiser inspects the property and submits an appraisal report, but that report is not the operative value document. The lender's Staff Appraisal Reviewer (SAR) under the Lender Appraisal Processing Program — or VA staff where LAPP does not apply — reviews the report and issues the Notice of Value (NOV), which establishes the reasonable value and every condition that must be satisfied before VA will guarantee the loan. An NOV is valid for six months. Older prep texts call this document the Certificate of Reasonable Value (CRV); VA Pamphlet 26-7, Chapter 13 has used Notice of Value for years, so treat CRV as legacy vocabulary and NOV as the current answer.
  • If the appraiser signals that value will come in under contract price, the Tidewater procedure gives the requester two business days to submit additional market data before the report is finalized. After the NOV issues, the parties may request a Reconsideration of Value (ROV).
  • If the contract price exceeds the NOV, the veteran may pay the difference in cash, renegotiate the price, or withdraw and recover the deposit under the mandatory VA Escape Clause (38 U.S.C. 3703(c)(1)), which must appear in the contract.
• Underwriting: Evaluated against a single benchmark ratio of 41% total DTI, combined with strict residual income requirements—the net cash remaining for family sustenance after paying housing costs, debt service, and taxes.

USDA / Rural Housing Service Loans

The United States Department of Agriculture (USDA) Section 502 Guaranteed Rural Housing Loan program provides 100% financing (zero down payment) for moderate-income borrowers purchasing primary residences in designated rural and suburban communities. Borrowers must meet strict household income caps (not exceeding 115% of the Area Median Income) and the subject property must be located in an approved USDA geographic territory.

Specialized Mortgage Structures

Fixed-Rate Mortgages (FRM)

A fixed-rate mortgage retains an unchanging interest rate and level monthly principal and interest payment throughout the entire term (typically 15 or 30 years). In early loan years, the monthly payment is heavily weighted toward interest; over time, the amortization curve shifts so that the majority of each payment amortizes the principal.

Adjustable-Rate Mortgages (ARM)

An ARM features an interest rate that adjusts periodically based on changes in a specified financial index. Key mechanics include:

• Index: An independent financial economic indicator (such as the Secured Overnight Financing Rate - SOFR, or 1-Year Constant Maturity Treasury - CMT) beyond the lender's control.
• Margin: The lender's fixed markup/profit spread (e.g., 2.50%) added to the index. The margin remains constant throughout the entire loan life.
• Fully Indexed Rate: Calculated as Index + Margin = Fully Indexed Rate.
• Adjustment Period: How frequently the rate adjusts (e.g., in a 5/1 ARM, the rate is fixed for the initial 5 years, then adjusts annually every 1 year thereafter).
• Interest Rate Caps: Consumer protections that limit rate fluctuations:
  • Initial Cap: Maximum increase at the first adjustment.
  • Periodic Cap: Maximum increase during any subsequent adjustment period.
  • Lifetime Cap: Absolute ceiling the interest rate can never exceed over the life of the loan.

Balloon Mortgages

A loan where monthly payments are calculated on a longer amortization schedule (such as 30 years), but the entire outstanding loan balance becomes immediately due and payable at an earlier maturity date (such as 5 or 7 years) in a single lump-sum "balloon payment."

Reverse Mortgages (HECM)

The Home Equity Conversion Mortgage (HECM) is an FHA-insured reverse mortgage designed for homeowners aged 62 or older with substantial equity in their primary residence. Borrowers receive loan advances (lump sum, monthly annuity, or credit line) without making monthly mortgage payments. The loan balance accrues over time and is repaid only when the borrower dies, sells the property, or permanently vacates for more than 12 consecutive months. The borrower retains legal title but must pay real estate taxes, hazard insurance, and property maintenance.

Bridge Loans

A bridge loan (swing loan) is short-term financing, typically 6 to 12 months, secured by the borrower's departing residence so the borrower can close on a replacement home before the current one sells. Bridge loans are interest-only or accrual-only, carry rates well above conventional first mortgages, and are repaid in a lump sum from the sale proceeds. They are underwritten on equity in the departing property rather than on the borrower's ability to carry both payments indefinitely.

• Broker use case: a New Jersey move-up buyer in a market where sellers will not accept a home-sale contingency.
• Principal risk: if the departing residence does not sell, the borrower carries two mortgages plus the bridge. Brokers must never characterize a bridge loan as risk-free "temporary" money.

Rehabilitation (Renovation) Loans

A rehab loan finances acquisition and improvement in a single closing, with renovation funds held in escrow and released by draw as work is completed and inspected.

The defining feature is that the loan amount is based on the as-completed appraised value, not the as-is price, which is what makes a rehab loan viable on distressed inventory that would not otherwise finance. Draw schedules, licensed-contractor requirements, and completion deadlines are underwritten conditions, and delays trigger default. In New Jersey, renovation-loan work that alters structure or systems also requires municipal construction permits under the Uniform Construction Code.

Construction Loans

A construction loan funds ground-up building on a per-draw basis with interest charged only on drawn balances; a construction-to-permanent loan converts to an amortizing mortgage at certificate of occupancy in a single closing. In New Jersey, a builder selling newly constructed homes must be registered under the New Home Warranty and Builders' Registration Act, and buyers of new construction receive both the statutory warranty and the off-site conditions notice.
