Title: What Is a First Mortgage — How It Works, How It Differs from a Second Mortgage, and Practical Steps for Borrowers
Key takeaways
– A first mortgage is the primary lien on a property; it has priority over any other liens if the borrower defaults.
– “First mortgage” means the first (senior) loan secured by a particular property, not necessarily the borrower’s first-ever home loan.
– Loan-to-value (LTV) affects requirements and whether private mortgage insurance (PMI) is required; LTV > 80% typically triggers PMI on conventional loans.
– A second mortgage (home equity loan or HELOC) is subordinate to the first mortgage, usually carries a higher interest rate, and increases monthly obligations and default risk.
– There are clear practical steps for obtaining, managing, and if necessary modifying or refinancing first and second mortgages.
What is a first mortgage?
A first mortgage is the primary loan secured by a property and recorded as the senior lien. It’s the loan that must be repaid first out of any proceeds if the property is sold or foreclosed. The term refers to the mortgage’s priority on that property, not the borrower’s order of mortgages across different properties. If you refinance the first mortgage, the new loan replaces the original as the first lien.
How first mortgages work
– Borrower applies to a lender, gets approved, and signs loan documents.
– The lender records a lien on the property; monthly payments typically include principal and interest (and often escrow for taxes and insurance).
– The borrower’s equity equals the property’s value minus outstanding liens.
– Mortgage interest on qualified first mortgages may be tax-deductible for taxpayers who itemize (see IRS guidance).
First mortgage requirements (overview)
Requirements vary by loan type and lender, but common factors include:
– Credit score and credit history.
– Debt-to-income (DTI) ratio and steady verifiable income.
– Down payment size (conventional vs. government-backed).
– Property type and condition (single-family, multi-unit, investment property rules differ).
Examples:
– FHA loans can allow down payments as low as 3.5% with credit scores as low as about 580, but the property must meet FHA standards.
– Conventional loans typically require higher credit scores and larger down payments to avoid PMI.
Loan-to-Value (LTV) and PMI
– LTV = mortgage amount / appraised value.
– Conventional lenders commonly require PMI if the first mortgage LTV > 80%.
– PMI can often be removed when LTV reaches 78% (automatic cancellation under the Homeowners Protection Act occurs in many cases; you can request removal earlier when you reach 80% LTV and meet lender conditions).
– Borrowers sometimes use a smaller first mortgage (80% LTV) plus a second mortgage to avoid PMI; whether that is economical depends on interest rates and expectations for home value appreciation.
First mortgage vs. second mortgage
– First mortgage = senior lien; second mortgage = junior lien (subordinate).
– Second mortgages include home equity loans and HELOCs; they typically carry higher interest rates because they are riskier for the lender.
– In a foreclosure sale, proceeds pay the first mortgage balance first, then any remaining funds go to junior lienholders.
Illustrative example
– First mortgage: $250,000. Years later borrower owes $200,000 remaining.
– Second mortgage: $30,000.
– If property sells for $210,000 in foreclosure: first lender receives $200,000 (paid first), second lender receives remaining $10,000. Second lender may suffer a loss on the unpaid balance.
Fast facts
– “First mortgage” = priority on the property, not chronological first mortgage across a borrower’s life.
– Refinancing the first mortgage creates a new first mortgage.
– Mortgage interest can be tax-deductible if rules are met (consult IRS guidance).
– Second liens elevate monthly payments and default risk.
Practical steps — Getting a first mortgage
1. Check and improve your credit score; dispute errors on your credit report.
2. Determine your budget and target price range using a realistic DTI calculation.
3. Save for down payment and closing costs; consider programs (FHA, VA, USDA) if eligible.
4. Get prequalified/preapproved to understand loan amount and interest rate options.
5. Shop lenders and compare APRs, fees, and loan terms.
6. Choose property and complete appraisal and underwriting.
7. Close the loan and review escrow requirements for taxes/insurance.
8. Set up payments and maintain emergency savings.
Practical steps — Taking a second mortgage (home equity loan or HELOC)
1. Determine how much equity you have (current market value minus outstanding liens).
2. Shop products: fixed-rate home equity loans vs. variable-rate HELOCs.
3. Compare interest rates, closing costs, draw terms (for HELOCs), and repayment terms.
4. Confirm combined LTV limits (many lenders cap combined LTV at 80–90%).
5. Review budget to ensure you can meet combined monthly payments.
6. Close and manage the loan responsibly—prioritize repayment to avoid increased default risk.
Practical steps — Removing PMI or avoiding it
– To avoid PMI: save a 20% down payment or pair an 80% first mortgage with a second lien (weigh costs carefully).
– To remove PMI: request lender cancellation when your loan balance reaches 80% of original value (or current appraised value if allowed) and automatic cancellation generally occurs at 78% LTV. Provide proof of payments and current value if required.
Practical steps — If you’re struggling to pay
1. Contact your servicer immediately—early communication increases options.
2. Explore loss mitigation options: loan modification, forbearance, repayment plans.
3. Consider short sale or deed in lieu of foreclosure if you cannot keep the property.
4. Seek credit counseling or a HUD-approved housing counselor.
5. If you have a second mortgage, discuss options with both lenders; sometimes renegotiation or refinancing both loans into one first mortgage helps.
When refinancing makes sense
– Refinance to lower rate/term, reduce monthly payment, or consolidate second mortgage debt into a new first mortgage if the interest savings and costs are favorable.
– Run a break-even analysis of closing costs vs. monthly savings.
Is taking a second mortgage a good idea?
– It can be, for home improvements, debt consolidation, or short-term liquidity needs—if you can comfortably afford both payments, understand risks, and use proceeds for investments that improve home value or your financial position.
– It’s not a good idea if income is unstable, you lack emergency savings, or you’re using home equity to fund discretionary spending that won’t generate returns.
The bottom line
A first mortgage is the senior lien that secures the largest (or original) loan on a property and has priority in repayment. Second mortgages are subordinate and riskier for lenders, so they typically cost more. Before taking any mortgage, evaluate your credit, budget, loan terms, and long-term plans. If you run into trouble, act early and contact your lender and a housing counselor.
