The Two Documents That Make Up Your Mortgage
Most homebuyers don't realize they're signing two separate legal instruments at closing. The promissory note is your personal promise to repay the loan — it specifies the loan amount, interest rate, repayment schedule, and your personal liability for the debt. The mortgage (or deed of trust in many states) is the security instrument that creates the lender's lien on the property — giving the lender the right to foreclose if you default. The note is the debt; the mortgage is the collateral agreement securing that debt. When your loan is sold to another servicer, your payment address changes but the terms don't — both documents remain fully in effect.
Fixed Rate vs. Adjustable Rate: What Your Agreement Locks In
Fixed-rate mortgages maintain the same interest rate and monthly payment for the entire loan term — typically 15 or 30 years. Adjustable-rate mortgages (ARMs) start with a fixed period (typically 5, 7, or 10 years), then adjust periodically based on a benchmark index. ARM agreements specify the index (SOFR is now common), the margin (a fixed percentage added to the index), the adjustment frequency, the per-adjustment cap, and the lifetime cap. A 5/1 ARM with a 2/6 cap structure means fixed for 5 years, then annual adjustments capped at 2% per adjustment and 6% over the life of the loan. Always calculate your maximum possible payment before taking an ARM.
Escrow: Why Your Payment Is Higher Than You Expected
Most mortgages require an escrow account — a separate account managed by the lender that collects a portion of your monthly payment to cover property taxes and homeowners insurance when they come due. Your monthly payment is typically PITI: Principal, Interest, Taxes, and Insurance. The tax and insurance portions go into escrow; the lender pays the bills when due. The escrow amount adjusts annually based on actual tax and insurance bills. If your escrow is underfunded — because taxes or insurance increased — the lender may require a lump-sum catch-up payment or increase your monthly payment. PMI, required when your down payment is below 20%, may also be collected through escrow.
Default, Acceleration, and Foreclosure: Your Rights Before You Lose the Home
Mortgage default typically begins with missed payments. After 30 days, the delinquency is reported to credit bureaus. Most mortgages have an acceleration clause: after a specified period of default (typically 90–120 days), the lender can declare the entire outstanding balance immediately due. Federal law requires lenders to wait until you're 120 days delinquent before initiating foreclosure and to offer loss mitigation options first — loan modifications, repayment plans, forbearance, or a short sale. Foreclosure timelines vary dramatically by state: judicial foreclosure takes 12–36 months in many states; non-judicial foreclosure can happen in as little as 90–120 days in others.
Due-on-Sale Clause: Why You Can't Transfer a Mortgage
Nearly all modern mortgages contain a due-on-sale clause, which requires the entire loan balance to be paid immediately if the property is sold or transferred. This prevents buyers from assuming a seller's below-market-rate mortgage without lender approval. The clause is triggered by: selling the property, transferring title, placing the property in a trust (with exceptions for living trusts), and in some cases adding a co-owner to the title. FHA and VA loans are often assumable — conventional mortgages almost never are. Transferring title without paying off the mortgage gives the lender the right to accelerate the loan immediately.
PMI: When It Applies and How to Remove It
PMI (Private Mortgage Insurance) is required by most conventional lenders when your down payment is less than 20%. PMI protects the lender — not you — if you default. It typically costs 0.5–1.5% of the loan amount annually. The Homeowners Protection Act gives you the right to request PMI cancellation when your loan-to-value ratio reaches 80% based on the original purchase price and loan balance. PMI must be automatically terminated when the balance reaches 78% of the original purchase price. If your home's value has increased significantly, you may be able to request a new appraisal to terminate PMI sooner, though lender rules vary.
