What is Conventional Manual Underwriting?

Understanding when and why manual review is needed for conventional loans

Conventional loans are typically processed through Desktop Underwriter (DU)from Fannie Mae or Loan Product Advisor (LPA) from Freddie Mac. These automated systems analyze your credit, income, and assets to make instant approval decisions.

When these systems return a "Refer" or"Caution" decision—or when your situation doesn't fit standard parameters—manual underwriting allows a human underwriter to review your complete file and make a decision based on the full picture.

Manual underwriting is common for borrowers with limited credit history,self-employment income, recent credit events, or other situations that automated systems struggle to evaluate properly.

Conventional vs. Government Loans: Conventional loans have stricter requirements than FHA/VA but offer advantages like removable PMI, no upfront funding fees, and often lower total costs for borrowers with good credit.

The Manual Underwriting Process

Here's what to expect when getting a conventional loan with manual underwriting.

1

Initial Consultation

2

Credit Analysis

We pull your credit and identify any issues. If you have limited traditional credit, we discuss non-traditional credit options.

3

Document Collection

We provide a detailed checklist based on your specific situation. Complete documentation is critical for manual underwriting success.

4

Pre-Approval

Once we verify your documentation, we issue a pre-approval letter showing sellers you're a qualified buyer.

Frequently Asked Questions

Common questions about conventional manual underwriting.

What is the minimum credit score for conventional manual underwriting?

Fannie Mae and Freddie Mac require a minimum 620 credit score for conventional loans, including those with manual underwriting. However, many lenders have overlays requiring 680+ for manual review. NorthStar Funding follows agency guidelines and can work with 620+ scores when compensating factors are present.

How is conventional manual underwriting different from FHA or VA?

Conventional manual underwriting follows Fannie Mae or Freddie Mac guidelines, which are generally stricter than FHA/VA. Conventional loans require higher credit scores (620 vs. 500 for FHA), larger down payments (5% vs. 3.5% for FHA), and have tighter DTI limits. However, conventional loans avoid mortgage insurance once you reach 20% equity.

Can I get a conventional loan with non-traditional credit?

Yes, Fannie Mae allows non-traditional credit for borrowers with limited credit history. You'll need at least 3 non-traditional references (rent, utilities, insurance, etc.) with 12 months of payment history. Manual underwriting is required, and you'll typically need a larger down payment and strong compensating factors.

What are the waiting periods after bankruptcy for conventional loans?

For Chapter 7 bankruptcy: 4 years from discharge date (2 years with extenuating circumstances). For Chapter 13: 2 years from discharge or 4 years from dismissal. Extenuating circumstances (job loss, medical emergency, divorce) can reduce waiting periods but require documentation and manual underwriting.

What is the maximum DTI for conventional manual underwriting?

The standard maximum DTI is 45% for conventional loans. With strong compensating factors (high credit score, significant reserves, low LTV), DTI can go up to 50% with DU approval. Manual underwriting typically requires stronger compensating factors for DTI above 43%.

Do I need PMI with conventional manual underwriting?

Private Mortgage Insurance (PMI) is required for conventional loans with less than 20% down payment, regardless of underwriting method. The advantage of conventional loans is that PMI can be removed once you reach 20% equity, unlike FHA's lifetime mortgage insurance on most loans.

Can self-employed borrowers get conventional loans with manual underwriting?

Yes, self-employed borrowers often require manual underwriting due to complex income documentation. You'll need 2 years of tax returns, year-to-date P&L, and possibly a CPA letter. Manual underwriting allows the underwriter to analyze your business income trends and stability more thoroughly.

What reserves are required for conventional manual underwriting?

Reserve requirements vary: 2 months PITI for primary residence, 6 months for second homes, and 6 months for investment properties. Manual underwriting may require additional reserves as a compensating factor, especially for higher DTI ratios or lower credit scores.
