Loan-to-Value Ratio (LTV) Explained for Business and Real Estate Loans

When you borrow against an asset — a building, a piece of equipment, an investment property — the lender doesn't just evaluate your creditworthiness. They evaluate how much the asset is worth relative to how much you're borrowing against it. That relationship is Loan-to-Value Ratio, or LTV.

LTV is one of the most fundamental concepts in secured lending, and it affects three things directly: whether you're approved, how much you can borrow, and what rate you'll pay.

The LTV Formula

LTV = Loan Amount ÷ Appraised Value of Asset

Expressed as a percentage:

• $750,000 loan on a $1,000,000 property = 75% LTV
• $400,000 loan on a $500,000 building = 80% LTV
• $160,000 loan on a $200,000 piece of equipment = 80% LTV

The inverse of LTV is your equity position (or down payment): 75% LTV means 25% equity. 80% LTV means 20% equity.

Why Lenders Care About LTV

LTV is a measure of the lender's risk cushion. If a borrower defaults and the lender has to foreclose and sell the asset, LTV determines whether the proceeds will cover the outstanding loan balance.

At 70% LTV, the property value can decline 30% before the lender is underwater. At 90% LTV, a 10% decline in value wipes out the cushion. Lower LTV = more protection for the lender = lower risk = better terms for the borrower.

This is why lenders consistently offer lower rates at lower LTV. It's not arbitrary — lower LTV genuinely means lower risk for them.

LTV Limits by Loan Type

SBA 504 (owner-occupied commercial real estate): Up to 90% LTV (10% down payment). The SBA's guarantee provides the additional risk coverage that allows this lower down payment than conventional financing.

SBA 7(a) (commercial real estate): Up to 85–90% LTV for well-qualified borrowers. Higher LTV than conventional because of the government guarantee.

Conventional commercial mortgage (owner-occupied): Typically up to 75–80% LTV, requiring 20–25% down.

Conventional commercial mortgage (investment property): Typically up to 65–75% LTV, requiring 25–35% down.

Residential investment property (conventional): Up to 75–80% LTV (20–25% down).

DSCR loans: Up to 75–80% LTV on purchase; 70–75% on cash-out refinance.

Equipment financing: Up to 80–100% LTV for new equipment from qualified borrowers; lower for used or specialty equipment.

Hard money / bridge loans: Typically 65–75% of current value, or 70–75% of as-stabilized value for value-add properties.

How LTV Affects Your Interest Rate

Most lenders price risk in tiers. Lower LTV = lower rate. Higher LTV = higher rate (or additional requirements like mortgage insurance or personal guarantee).

Example pricing tiers on a commercial real estate loan:

• LTV under 60%: Best available rate (e.g., 6.5%)
• LTV 60–65%: Standard rate (e.g., 6.75%)
• LTV 65–70%: Slight add-on (e.g., 7.0%)
• LTV 70–75%: Add-on (e.g., 7.25%)
• LTV above 75%: Higher add-on or requires additional mitigants

The rate differential between 60% LTV and 75% LTV may seem small in percentage terms. On a $1,000,000 loan over 25 years, it's tens of thousands of dollars in interest.

Appraised Value vs. Purchase Price

An important nuance: LTV is calculated on the appraised value, not necessarily the purchase price. When these differ, lenders use the lower of the two.

If you're buying a property for $800,000 but it appraises at $750,000, the lender calculates LTV on $750,000 — even though you're paying $800,000. At 75% LTV on the appraised value, you can borrow $562,500. The remaining $237,500 ($800,000 purchase price minus $562,500 loan) must come from your pocket.

Low appraisals are one of the most common surprises in commercial real estate closings. Understanding this dynamic before you're under contract prevents nasty surprises at closing.

Combined LTV (CLTV)

When a property has multiple loans — a first mortgage and a second mortgage, or a bank loan and an SBA debenture (as in the 504 structure) — lenders calculate Combined Loan-to-Value (CLTV).

CLTV = (All Loan Balances Combined) ÷ Appraised Value

SBA 504: $500,000 bank loan + $400,000 SBA debenture on a $1,000,000 property = 90% CLTV. This is the maximum the 504 structure allows.

LTV and Equipment Financing

Equipment LTV works the same conceptually but has some practical differences:

• New equipment: Lenders often use invoice price as value (100% financing of purchase price = 100% LTV, but invoice price is often a reasonable proxy for value)
• Used equipment: Lenders use appraised market value, which may be significantly lower than asking price. A $150,000 used excavator may appraise at $110,000, limiting borrowing to $88,000 at 80% LTV.
• Age matters: Lenders often have maximum age limits for equipment (10–15 years for heavy equipment), beyond which financing is unavailable or very limited
