If you are new to mortgage vocabulary, start with Mortgage, Home Loan, Secured Loan, Collateral, Purchase Price, Loan Amount, Loan Proceeds, Mortgage Obligation, Original Principal Balance, Principal, Principal Balance, Payoff Amount, Interest, Accrued Interest, Total Interest, Principal and Interest (P&I), and Monthly Payment. Those pages establish the core ideas that show up again in underwriting, closing, refinancing, and servicing.

When those basics feel clear, move into First Payment Date, Scheduled Payment, Payment Frequency, Payment Schedule, Loan Term, Remaining Term, Maturity Date, Amortization, Reamortization, Negative Amortization, and Amortization Schedule to see how the balance changes over time, then compare Loan Originator, Mortgage Lender, Correspondent Lender, and Mortgage Broker before exploring Loan Types.

For payment strategy vocabulary, compare Extra Principal Payment, Biweekly Mortgage Payment, Principal Curtailment, and Mortgage Recast so optional balance reduction does not get confused with the required scheduled payment.

As the section expands, it also covers how the borrowing process starts in practice through Mortgage Application, Uniform Residential Loan Application, Loan File, Loan Number, Borrower Authorization, Credit Authorization, Loan Purpose, Occupancy Statement, and Mortgage Commitment, plus the day-to-day lender contact role of the Loan Officer.

If the legal paperwork feels abstract, stay in the document lane: read Mortgage, then compare Mortgage Borrower, Mortgagor, Mortgagee, Mortgage Holder, Note Holder, Promissory Note, Mortgage Note, Mortgage Obligation, Note Date, Electronic Note (eNote), and Principal and Interest (P&I) so the party labels, loan promise, collateral framework, document format, and payment labels do not blur together.
