Second Mortgage 2026: Rates, Requirements & How It Works
Borrow up to 85% of home value · Rates from 8% APR · Keep your first mortgage rate
Access your home equity without refinancing your first mortgage
Quick Answer
A second mortgage lets you borrow against your home equity without touching your first mortgage. Rates run 8-12% APR, you can borrow up to 85% of your home value (combined with first mortgage), and you need a 680+ credit score with 15-20% equity. The two main types are home equity loans (lump sum, fixed rate) and HELOCs (revolving credit, variable rate). Compare lenders at MRC to find the best second mortgage for your needs.

How Much Can You Borrow with a Second Mortgage?
Most lenders allow a combined LTV (loan-to-value) of 80-85%. Here is how to calculate your borrowing power:
Max Second Mortgage = (Home Value × 85%) − First Mortgage Balance
Home Value: $300,000
First Mortgage: $180,000
Max 2nd Mortgage: $75,000
Home Value: $500,000
First Mortgage: $300,000
Max 2nd Mortgage: $125,000
Home Value: $700,000
First Mortgage: $400,000
Max 2nd Mortgage: $195,000
Second Mortgage Requirements (2026)
15-20% Equity Minimum
Your combined LTV (first + second mortgage) must stay below 80-85%. Most lenders require at least 15% equity after the second mortgage.
680+ Credit Score
Most lenders require 680+. Some accept 620 with higher rates. 740+ gets the best rates. Lower scores mean higher APRs.
DTI Below 43%
Your total monthly debt including both mortgages must be below 43% of gross income. Some lenders allow 50% with strong reserves.

Frequently Asked Questions
What is a second mortgage?
A second mortgage is a loan that uses your home as collateral, in addition to your primary (first) mortgage. It allows you to borrow against your home equity without refinancing your first mortgage. The two main types are home equity loans (lump sum, fixed rate) and HELOCs (revolving credit line, variable rate).

Second mortgage rates in 2026 typically range from 8% to 12% APR. Home equity loans have fixed rates around 8.5-10%, while HELOCs have variable rates starting around 8.5%. Rates are higher than first mortgages because the second mortgage is riskier for the lender — if you default, the first mortgage gets paid first.
→ Compare second mortgage lenders — free, no obligationHow much can I borrow with a second mortgage?
Most lenders allow you to borrow up to 85% of your home value combined (first mortgage + second mortgage). For example, if your home is worth $400,000 and you owe $200,000 on your first mortgage, you could borrow up to $140,000 with a second mortgage ($340,000 total = 85% of $400,000).
→ Compare second mortgage lenders — free, no obligationWhat credit score do I need for a second mortgage?
Most second mortgage lenders require a credit score of 680 or higher. Some lenders accept 620+ but with higher rates. You also need at least 15-20% equity in your home and a debt-to-income ratio below 43%. Scores above 740 qualify for the best rates.
→ Compare second mortgage lenders — free, no obligationIs a second mortgage better than a cash-out refinance?
A second mortgage is better if you have a low interest rate on your first mortgage and do not want to lose it. A cash-out refinance is better if current rates are lower than your existing rate or you need more than 85% of your home value. Second mortgages have lower closing costs (2-5% vs 3-6%) but higher rates.
→ Compare second mortgage lenders — free, no obligationCan I get a second mortgage with bad credit?
Getting a second mortgage with bad credit (below 620) is very difficult. Some specialized lenders may approve 580+ but with rates of 12-15%+ and strict equity requirements (30%+ equity). If you have bad credit, consider improving your score first or using a personal loan which does not require home equity.
