How Public Sector Banks Calculate Mortgage Business Loan & OD Eligibility (Inside the Sanction Desk)

Every week, MSME owners walk into Public Sector Bank (PSB) branches with a residential house or commercial shop valued at ₹1.20 Crore, expecting a ₹80 Lakh business loan—only to be shocked when the branch sanctions ₹54 Lakh or rejects the Overdraft (OD) request completely.

Why does this happen? Because banks do not sanction Mortgage Business Loans (such as Loan Against Property and Overdraft facilities) based on a single property percentage. Instead, the credit officer runs your file through a strict 4-Way "Lowest Of" Formula and a Monthly Take-Home Income Check.

Here is the exact step-by-step math used inside a PSB credit desk so you can calculate your exact loan eligibility—and structure your file properly—before submitting your application.


1. Term Loan vs. Overdraft (OD): What Property Is Eligible?

Under updated Public Sector Bank mortgage guidelines for MSMEs (covering manufacturing, trading, and service units with a valid Udyam Registration Certificate), you can avail finance from ₹2 Lakh up to ₹10.00 Crore in two forms:

  • Term Loan (Up to 120 Monthly EMIs): Repaid over up to 10 years (including moratorium).
  • Overdraft (OD) Facility (Annual Review): Interest is charged only on the daily utilized amount, subject to annual review. Fresh Overdraft facilities can be sanctioned against both self-occupied residential properties and self-occupied commercial (constructed) properties (on a reducing Drawing Power / EMI basis).

Critical Rejection Trap (Vacant Plots): Never apply for a standard PSB Mortgage Business Loan offering an empty plot as your primary security. Loans on vacant plots are strictly not allowed under standard MSME mortgage schemes—the property must be a constructed residential, commercial, or industrial building.


2. The 4-Filter "Lowest Of" Formula (Maximum Loan Quantum)

When a branch manager or credit officer calculates your maximum sanction amount, they calculate four separate numbers and sanction the LOWEST of the four:

Filter 1: Location-Wise Maximum Cap

Depending on where your branch and property are located, PSBs apply an overall scheme ceiling:

  • Rural Centres (Population ≤ 10,000): Minimum ₹2 Lakh to Maximum ₹50 Lakh.
  • Semi-Urban (at District Headquarters): Minimum ₹2 Lakh to Maximum ₹10.00 Crore (₹1,000 Lakh).
  • Urban & Metro Centres: Minimum ₹5 Lakh to Maximum ₹10.00 Crore (₹1,000 Lakh).

Filter 2: Income & Cash Accrual Multiplier (3x vs. 5x Rule)

Your business must have a minimum gross annual income of ₹2.00 Lakh and a positive Tangible Net Worth (TNW). From there, banks separate borrowers into two categories:

  • For Individuals, Proprietorships & HUFs (3x Multiplier): Maximum eligibility is 3 times your Gross Annual Income as per your latest Income Tax Return (ITR). (Pro-Tip: Family income can be clubbed if close relatives join the loan as co-borrowers!)
  • For Partnership Firms, LLPs & Pvt. Ltd. Companies (5x Multiplier): Maximum eligibility is 5 times the Average Annual Cash Accrual of the last 3 years.
    Formula: Annual Cash Accrual = Profit After Tax (PAT) + Depreciation.

Filter 3 & Filter 4: The Property Valuation Dual-Cap (50% MV vs. 75% RV)

When the bank's approved valuer inspects your property, the valuation report contains two values: Market Value (MV) and Realizable Value (RV). The bank caps your loan at the lower of:

  • 50% of the Market Value (MV) of the property, OR
  • 75% of the Realizable Value (RV) of the security.

3. Real-World Sanction Calculation Example (₹1.20 Crore Property)

Let’s see how a PSB credit officer calculates the final sanction amount for two different borrowers offering the exact same commercial property in an Urban city:

  • Valuer's Market Value (MV): ₹1,20,00,000 (₹1.20 Crore)
  • Valuer's Realizable Value (RV): ₹96,00,000 (₹96 Lakh)
Assessment Filter Case A: Proprietorship (ITR ₹12L + Spouse ₹6L = ₹18L) Case B: Pvt. Ltd. Company (Avg PAT ₹10L + Depr ₹4L = ₹14L Cash Accrual)
1. Location Cap (Urban) ₹10,00,00,000 (₹10 Cr) ₹10,00,00,000 (₹10 Cr)
2. Income Eligibility 3 × ₹18 Lakh = ₹54,00,000 5 × ₹14 Lakh = ₹70,00,000
3. 50% of Market Value 50% of ₹1.20 Cr = ₹60,00,000 50% of ₹1.20 Cr = ₹60,00,000
4. 75% of Realizable Value 75% of ₹96 Lakh = ₹72,00,000 75% of ₹96 Lakh = ₹72,00,000
FINAL SANCTION ₹54,00,000 (Capped by 3x ITR) ₹60,00,000 (Capped by 50% MV)

4. The Monthly "Take-Home Income" Filter (FOIR Check)

Even after passing the 4-filter test above, your file must pass the Monthly Serviceability Test:

  • For Term Loans (50% Rule): Your total monthly deductions (existing EMIs + proposed new loan EMI) must be ≤ 50% of your gross monthly income (relaxable up to 60% in specified cases).
  • For Overdraft Limits (30% Rule): The monthly notional interest on the full OD limit must be ≤ 30% of your gross monthly income (up to 40% in relaxation cases).

5. Key Processing Fee Caps & Ownership Rules

  • Processing Fee Cap (Huge Saving): Unlike private lenders charging 1%–1.5% uncapped fees, PSB mortgage schemes cap processing charges at 0.25% (max ₹20,000 + GST) for Term Loans and 0.50% (max ₹20,000 + GST) for fresh Overdrafts (with annual renewal at just 0.10% or max ₹10,000 + GST).
  • Minimum Credit Score Required: Minimum CIBIL / CRIF score of 675 for individuals, and CMR-6 or better for firms/companies.
  • Property Ownership Rule: Property standing in the name of defined relatives is allowed if they join as co-borrowers. Personal property owned by partners/directors can be mortgaged for company loans, but company-owned properties cannot be mortgaged for personal director loans.

Pre-Application Document Checklist

  1. Udyam Registration Certificate & GST Registration.
  2. Last 3 Years ITR with Computation, P&L, and Balance Sheet (Positive Net Worth).
  3. Complete Chain of Property Title Deeds for the Panel Advocate's Legal Search Report (LSR).
  4. CIBIL / CRIF Report (≥ 675).

Frequently Asked Questions (FAQs) on PSB Mortgage & OD Loans

1. Why is my PSU bank mortgage loan amount lower than 60% or 75% of my property's market price?

Public Sector Banks (PSBs) do not sanction loans based solely on property value. Your application must pass the 4-Filter "Lowest Of" Formula. Even if your property's Market Value (MV) and Realizable Value (RV) are high, the sanction desk will cap your loan at the lowest figure among four checks: the scheme's location cap, 50% of Market Value, 75% of Realizable Value, and your Income/Cash Accrual Multiplier (3x Gross Annual Income for Proprietorships or 5x Cash Accruals for Partnerships/Pvt Ltd firms).

2. Can I get an MSME Mortgage Overdraft (OD) against a vacant plot or agricultural land in SBI, PNB, or Bank of Baroda?

No. Under standard PSB retail mortgage and MSME Loan Against Property (LAP) schemes, loans against vacant plots or agricultural land are strictly disallowed. The collateral must be a constructed residential, commercial, or industrial building. Furthermore, for an Overdraft (OD) facility, banks typically require the collateral to be a self-occupied residential or commercial property.

3. What is the minimum CIBIL score and CMR Rank required for a PSU bank business mortgage loan?

For individual proprietors, promoters, and guarantors, PSBs generally require a minimum personal CIBIL score of 675. For non-individual entities (Partnership Firms, LLPs, and Private Limited Companies), banks check the CIBIL MSME Rank and require a score between CMR-1 and CMR-6 (where CMR-1 is the lowest risk and CMR-10 is the highest risk).

4. Can I mortgage a property owned by my family member or company director for a business loan?

Yes, with specific conditions. Property standing in the name of defined close relatives (such as parents, spouse, or children) can be mortgaged provided the property owner joins the loan structure as a Co-borrower and Guarantor. Similarly, personal property owned by Partners or Directors can be mortgaged for a firm's business loan. However, a company-owned commercial property cannot be mortgaged to secure a personal loan for a director.
