How to Calculate Loan-to-Value Ratio

Loan-to-value ratio measures how much of a property's value is financed by debt. The formula is simple: divide the total loan balance by the current property value, then multiply by 100. An LTV of 80% means the lender has financed 80% of the property's value and the owner holds 20% equity.

For rental property investors, LTV is one of the most important metrics because it determines loan eligibility, interest rates, insurance requirements, and refinancing options. Lenders use LTV to assess risk: higher LTV means the borrower has less equity at stake, which increases the lender's exposure if the property loses value.

Why LTV Matters for Rental Property Investors

LTV directly affects borrowing costs. Most conventional lenders require private mortgage insurance (PMI) when LTV exceeds 80%, adding $50 to $200 or more per month to the carrying cost of the property. PMI protects the lender, not the borrower, so eliminating it by reaching 80% LTV directly improves cash flow.

Refinancing terms also improve as LTV decreases. Borrowers with LTV below 75% typically qualify for the best available interest rates, while those above 80% face higher rates and may have fewer lender options. For cash-out refinancing, where the borrower pulls equity out of the property as cash, most programs require LTV of 75% or lower after the cash-out.

LTV also serves as a risk gauge for the investor's own portfolio. A property at 95% LTV has almost no equity cushion. If property values decline by even 5%, the owner is underwater, meaning they owe more than the property is worth. Maintaining LTV below 80% across a portfolio provides a meaningful buffer against market corrections.

How Equity Builds Over Time

Equity in a rental property comes from two sources: principal paydown and property appreciation. Principal paydown is the portion of each mortgage payment that reduces the loan balance. In the early years of a 30-year mortgage, this is a small share of each payment, but it grows over time as the balance decreases and less interest accrues.

Appreciation increases the property value side of the equation without any action from the owner. If a property purchased for $180,000 is now worth $200,000, the owner has gained $20,000 in equity through appreciation alone. Combined with principal paydown, these two forces steadily reduce LTV over time even without extra payments.

Tracking both components separately helps investors understand where their equity is coming from. A property that has appreciated significantly but had minimal paydown may have a low LTV that could reverse if the market corrects. A property with heavy paydown but flat appreciation has equity that is more durable because it is not dependent on market conditions.

Key LTV Thresholds for Landlords

The 80% threshold is the most important for most borrowers because it eliminates PMI requirements on conventional loans. Reaching 80% LTV, whether through paydown, appreciation, or a combination, directly reduces monthly costs and improves cash-on-cash returns.

The 75% threshold unlocks premium refinancing terms and is the standard requirement for most cash-out refinance programs. Investors looking to pull equity from one property to fund a down payment on the next should target 75% LTV or lower before applying.

Below 60% LTV represents a very strong equity position where the borrower qualifies for the absolute best rates and has significant flexibility for HELOCs, portfolio lending, and commercial refinancing options that are not available at higher LTV levels.

Combined LTV for Multiple Loans

When a property has more than one loan, such as a first mortgage and a HELOC, lenders calculate combined loan-to-value (CLTV) by adding all loan balances together and dividing by the property value. A property worth $200,000 with a $140,000 first mortgage and a $20,000 HELOC has a CLTV of 80%.

CLTV matters because even if the first mortgage is at a low LTV, adding a second lien increases total leverage and affects the borrower's risk profile. Most HELOC lenders require CLTV below 80% to 85%, meaning the combined borrowing on the property cannot exceed that threshold regardless of how low the first mortgage balance is.

How to Reduce LTV Faster

Making extra principal payments is the most direct way to lower LTV. Each extra dollar paid reduces the loan balance immediately, and because interest is calculated on the outstanding balance, it also reduces the amount of future payments that go to interest.

Property improvements that increase appraised value can reduce LTV without any additional loan payments. A $10,000 kitchen renovation that increases the property's appraised value by $20,000 effectively moves LTV down by the equivalent of $20,000 in paydown, though the investor spent only $10,000.

Requesting a property reappraisal from the lender is another option when the market has appreciated since purchase. If the lender accepts a higher appraised value, LTV drops immediately. Some lenders allow this for PMI removal requests once the borrower believes the property has appreciated past the 80% LTV threshold.

Frequently Asked Questions

What is a good LTV ratio for rental property?

Below 75% is considered strong for rental property because it qualifies for the best refinancing rates and most cash-out programs. Below 80% eliminates PMI on most conventional loans. Most investment property loans start at 75% to 80% LTV with a 20% to 25% down payment.

How do you calculate LTV?

Divide the current loan balance by the current property value, then multiply by 100. For example, a $144,000 loan balance on a $200,000 property equals 72% LTV. If there are additional liens like a HELOC, add all balances together for combined LTV.

What LTV is needed to remove PMI?

Most conventional lenders remove PMI when LTV reaches 80% based on the original purchase price, or 78% for automatic removal. Some lenders allow early removal based on a new appraisal showing sufficient appreciation. Contact your lender for their specific PMI removal requirements.

Does LTV affect interest rates?

Yes. Lower LTV generally qualifies borrowers for lower interest rates because the lender faces less risk. The most significant rate improvements typically occur at the 80% and 75% LTV thresholds. Above 80% LTV, rates are higher and PMI adds additional cost.

What is the maximum LTV for investment property?

Most conventional lenders limit investment property loans to 80% LTV, requiring a 20% down payment. Some programs allow up to 85% with PMI. FHA and VA loans with lower down payments are generally limited to owner-occupied properties and do not apply to investment rentals.

Can appreciation lower my LTV?

Yes. If your property increases in value, the denominator of the LTV equation grows, which reduces the ratio even if you have not paid down any additional principal. You may need a new appraisal for your lender to officially recognize the higher value for PMI removal or refinancing.
