How Much Equity Do I Need for a Second Mortgage?
The amount of equity you need depends on the lender, the property and the complete financing request. The key calculation is the combined loan-to-value: everything secured against the property compared with its current value.
← Back to Second Mortgage QuestionsThe Lender Looks at the Total Debt Against the Property — Not Just the Second Mortgage.
To determine whether there is enough equity, we add the existing first mortgage, the proposed second mortgage and any other secured debt that must be considered, then compare that total with the property's current value.
Current Property Value
The starting point is the property's current market value. A current appraisal is commonly required to establish the value the lender will use.
First Mortgage Balance
The amount already owing on the first mortgage uses part of the property's available equity.
Proposed Second Mortgage
The new second mortgage is added to the existing secured debt when calculating the combined loan-to-value.
Other Secured Debt
Other mortgages, liens, judgments or secured obligations affecting the property may also need to be included in the calculation.
Lender Maximum LTV
Different lenders have different maximum loan-to-value limits depending on the property, location and overall risk of the file.
Property Type and Location
A lender may be more conservative on certain property types or locations, which can affect how much equity needs to remain.
Equity Is the Room Between the Property Value and the Debt Secured Against It.
Suppose a property is worth $800,000. The existing first mortgage is $500,000 and the homeowner wants a $100,000 second mortgage.
The total secured mortgage debt would be $600,000. Compared with an $800,000 property value, that represents a 75% combined loan-to-value.
This is the value used for the example.
This is the existing secured mortgage debt.
This brings the total secured mortgage debt to $600,000.
$600,000 divided by $800,000 equals a 75% combined loan-to-value.
More Equity Usually Creates More Lending Options.
The second mortgage lender sits behind the first mortgage lender, so the amount of equity remaining in the property is an important part of the lender's risk assessment.
Lower LTV Means More Cushion
A lower combined loan-to-value leaves more equity behind the mortgages and can reduce the lender's risk.
More Lender Choices
A stronger equity position can increase the number of lenders willing to consider the file.
Potentially Better Pricing
Loan-to-value is one factor that can affect the interest rate, lender fee and overall cost of the second mortgage.
More Room for Required Funds
Additional equity can make it possible to borrow enough to accomplish the actual purpose of the financing.
The Appraisal Matters
If the appraised value is lower than expected, the available equity and maximum second mortgage amount can change materially.
Equity Is Not the Only Factor
The lender may also consider credit, income, property marketability, mortgage payment history and the purpose of the funds.
The More Equity You Have, the More Second-Mortgage Options You Are Likely to Have.
There is no single equity percentage that applies to every second mortgage. We need the current property value, first mortgage balance, proposed second mortgage and any other secured debt to calculate the combined loan-to-value and determine which lenders may be available.
