Guide
Decode the full cost of a mortgage
Mortgage costs go far beyond principal and interest. This guide covers rate shopping, closing costs, escrow, PMI, and the tradeoffs behind term and down payment choices.
Overview
A mortgage costs more than the monthly payment shown on the marketing page
A mortgage’s sticker rate is what most shoppers compare. The actual all-in monthly cost is the sticker rate plus property taxes, homeowners insurance, mortgage insurance when applicable, and HOA dues when applicable — together called PITI(A). The CFPB’s Loan Estimate is the federally standardized document that puts all of this on one page; every lender must deliver it within three business days of application.
This guide explains how to read a Loan Estimate, how to compare two of them, and where money quietly leaks during the process. If you already have a mortgage and want to test whether refinancing makes sense, jump to the refinance break-even calculator for the math.

Rate vs APR
APR captures fees the interest rate hides
The interest rate determines the principal-and-interest portion of the monthly payment. The APR includes the interest rate plus most loan-related fees expressed as an annualized cost. Two lenders quoting the same interest rate can have very different APRs if one charges higher origination, underwriting, or rate-lock fees. APR is the right shopping number when comparing the same loan type and term.
The Loan Estimate’s page 3 shows the “In 5 Years” total — total paid in principal, interest, mortgage insurance, and fees over the first five years. That is often a better real-world comparison than APR alone because it incorporates the actual amortization schedule.
Discount points
When buying down the rate actually pays off
One discount point typically costs 1% of the loan amount and reduces the rate by a fraction of a percent (often around 0.25%, but it varies). The break-even is monthly-savings ÷ point-cost. If the break-even is 6 years and you plan to keep the loan for 10, points are likely worth it; if you plan to sell or refinance in 3, they are not.
PMI and MIP
Private mortgage insurance is removable; FHA MIP usually is not
On conventional loans, private mortgage insurance (PMI) is required when the down payment is under 20% and is removable once the loan balance reaches 80% loan-to-value (LTV) — automatically at 78% by federal Homeowners Protection Act rules. On FHA loans, the mortgage insurance premium (MIP) is structured differently and, for most current FHA loans, is not removable for the life of the loan unless you refinance into a conventional product. That difference can outweigh the FHA loan’s easier underwriting over the long run.
Closing costs
Where closing-day cash actually goes
Closing costs typically total 2–5% of the loan amount and are split into three buckets on the Loan Estimate: (A) services you can shop for (title, settlement, pest), (B) services you can’t shop for (appraisal, credit report, lender-required), and (C) taxes and prepaid items (transfer taxes, prepaid interest, escrow deposits). Bucket A is where price comparison pays off. Bucket C is usually unavoidable but should still be verified for accuracy.
For the line-by-line math comparing two specific offers, open the refinance break-even calculator and enter the figures from each Loan Estimate side by side.
FAQ
Common questions
How much should I shop around for a mortgage?
The CFPB’s research suggests that shoppers who collect quotes from at least three lenders pay measurably less. Multiple credit pulls within a 14–45 day window are typically treated by scoring models as a single inquiry for shopping purposes.
What is the difference between pre-qualified and pre-approved?
Pre-qualification is informal; pre-approval involves a credit check and documentation. Pre-approval letters carry weight in offers but are not loan commitments.
Is 20% down required to buy?
No. Conventional loans allow as little as 3% down with PMI; FHA loans 3.5%; VA and USDA can be 0% for qualified borrowers. The cost calculation differs across programs and should be compared on the Loan Estimate, not on advertised rates.
