When automated systems can't see the full picture, manual underwriting provides a path to conventional financing with competitive rates and no lifetime PMI.
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.
These situations typically trigger manual underwriting for conventional loans.
Fewer than 3 tradelines or less than 12 months of credit history
Using rent, utilities, or other non-traditional credit references
Complex income situations requiring detailed analysis
Bankruptcy, foreclosure, or short sale within waiting periods
When Desktop Underwriter or Loan Product Advisor returns a "Refer" decision
DTI above 45% with compensating factors that require human review
Key requirements for conventional loans with manual underwriting.
620 minimum for most programs; 680+ preferred for manual review
Minimum 5% for primary residence; 10-20% for investment properties
Maximum 45% DTI; up to 50% with strong compensating factors
At least 3 tradelines with 12+ months history; alternative credit considered

These factors can offset risk and help achieve approval with manual underwriting.
6+ months of PITI in liquid assets after closing
Down payment of 20% or more reducing risk
New payment within 5% of current housing expense
Credit score 720+ despite other risk factors
5+ years with same employer or in same field

Common questions about 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.
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.
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.
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.
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%.
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.
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.
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.
Let us help you determine if conventional manual underwriting is right for you—or if FHA or VA might be better options for your situation.
