Elena Rodriguez
Lead Mortgage Analyst | 12 Years in Mortgage Underwriting
Elena Rodriguez serves as the Lead Mortgage Analyst at MortgageCalc, where she oversees all calculator logic, formula validation, and lending product accuracy across the platform. Before joining MortgageCalc, Elena spent 12 years as a senior underwriter at one of the nation's top-five mortgage lenders, where she personally evaluated and approved over 4,000 residential loan applications totaling more than $1.2 billion in origination volume. Her underwriting experience spans conventional conforming loans, FHA and VA government-backed programs, jumbo non-conforming products, and portfolio lending for investment properties.
Elena holds a Bachelor of Science in Finance from the University of Texas at Austin and earned her Certified Mortgage Underwriter (CMU) designation through the National Association of Mortgage Underwriters. She has completed advanced coursework in regulatory compliance covering the Truth in Lending Act (TILA), the Real Estate Settlement Procedures Act (RESPA), and the Dodd-Frank Wall Street Reform Act. Her deep understanding of Debt-to-Income (DTI) ratio calculations, Loan-to-Value (LTV) thresholds, and automated underwriting systems (DU and LP) ensures that every tool on MortgageCalc mirrors the exact methodology used by institutional lenders.
At MortgageCalc, Elena is responsible for auditing all mathematical models, testing edge cases in our amortization and extra-payment simulators, and ensuring that our FHA, VA, and ARM calculators reflect the latest agency guidelines. She also reviews every blog post for technical accuracy before publication. When she is not stress-testing calculator outputs, Elena contributes to industry panels on responsible lending practices and mentors early-career underwriters through the Mortgage Bankers Association (MBA) mentorship program.

Marcus Sterling
Financial Editor | 15 Years in Personal Finance Journalism
Marcus Sterling is the Financial Editor at MortgageCalc, where he leads the editorial team in producing clear, actionable, and thoroughly researched content on mortgage planning, home buying, and real estate finance. With 15 years of experience in personal finance journalism, Marcus has written for several nationally recognized financial publications, including contributions to outlets covering housing market trends, Federal Reserve policy impacts on mortgage rates, and consumer lending regulations. His work has been cited by the Consumer Financial Protection Bureau (CFPB) and referenced in multiple state-level housing policy reports.
Marcus graduated summa cum laude with a Bachelor of Arts in Journalism from Northwestern University's Medill School of Journalism and later earned a Certificate in Financial Planning from Boston University. His dual background in rigorous investigative reporting and financial analysis gives him a unique ability to translate complex mortgage concepts — such as yield spread premiums, discount points, rate lock mechanics, and escrow impound analysis — into language that first-time home buyers and seasoned investors alike can understand and act upon. He is a firm believer that financial literacy is the single most powerful tool a consumer can wield when negotiating lending terms.
At MortgageCalc, Marcus oversees the editorial calendar, manages the blog publication pipeline, and enforces the site's strict fact-checking and sourcing standards. Every article published under the MortgageCalc brand must cite at least three authoritative external sources — such as the Federal Reserve, HUD, Fannie Mae, Freddie Mac, or the CFPB — and must be reviewed by Elena Rodriguez for mathematical accuracy before going live. Marcus also leads the development of our educational glossary, FAQ section, and seasonal market analysis reports that help users make informed decisions in any interest-rate environment.

Our Editorial Review Process
Transparency and accuracy are the cornerstones of everything we publish at MortgageCalc. Every piece of content on this site — whether it is a calculator output, a blog article, or a glossary definition — goes through a rigorous multi-step review process before it reaches our users.
Step 1: Research and Drafting
All content begins with thorough research using primary sources such as federal agency publications (HUD, CFPB, Federal Reserve), lending industry data from Freddie Mac and Fannie Mae, and regulatory filings. Our writers produce initial drafts grounded in verifiable data, citing specific sources for all statistical claims and regulatory references.
Step 2: Technical Review by Elena Rodriguez
Every article, calculator formula, and numerical example is reviewed by Elena Rodriguez for mathematical accuracy. She verifies that all amortization computations, rate calculations, PMI thresholds, and DTI examples conform to current industry underwriting standards. If a calculator update is involved, Elena runs parallel validation against institutional-grade underwriting software to confirm output accuracy within a margin of less than 0.01%.
Step 3: Editorial Review by Marcus Sterling
Marcus Sterling then reviews all content for clarity, readability, and compliance with our editorial standards. He ensures that technical jargon is properly defined, that the content flows logically for readers at all experience levels, and that every article meets our minimum sourcing requirements of three authoritative external references.
Step 4: Publication and Ongoing Monitoring
After passing both technical and editorial review, content is published with clear author attribution, publication dates, and last-updated timestamps. Our team conducts quarterly audits of all published content to ensure it remains current with evolving mortgage rates, regulatory changes, and agency guideline updates. If a significant policy change occurs — such as an FHA loan limit adjustment or a Federal Reserve rate decision — affected content is updated within 48 hours.
