How mortgages work in 2026

What a mortgage actually is

A mortgage is a loan secured by real property. The word comes from Old French and roughly translates to “death pledge.” You pledge the house as collateral until the loan is paid off or you die. If you stop paying, the lender can foreclose, meaning it takes legal possession of the property and sells it to recover its money.

The loan has two cost components: principal and interest. Principal is the amount you borrowed. Interest is the fee the lender charges for letting you use its money. Each monthly payment chips away at both, but not evenly. In the early years, most of your payment goes to interest. In the later years, most goes to principal. This front-loading of interest is called amortization, and it is why paying even an extra $200 per month early in a 30-year loan can shave years off the term and save tens of thousands in interest.

A concrete example

On a $400,000 mortgage at 6.85% over 30 years, your monthly payment is $2,623. In month one, $2,283 goes to interest and only $340 goes to principal. By month 360, the split has reversed: nearly the entire payment retires principal. Over the full life of the loan, you pay $544,491 in interest alone, which means you pay for the house twice over. That is not a scam; it is the price of spreading $400,000 across 360 months. But it is a number worth confronting before you sign.

Most mortgages in the US are fixed-rate: the interest rate never changes. Adjustable-rate mortgages (ARMs) start with a fixed period, often 5, 7, or 10 years, then float based on a benchmark index. ARMs can make sense if you plan to sell or refinance before the fixed period ends, but they carry rate risk after that.

How rates are set: the 10-year Treasury, MBS spreads, and the Fed

Mortgage rates do not come from the Fed directly, even though every news cycle implies they do. The Fed controls the federal funds rate, which is an overnight lending rate between banks. Mortgages are 30-year instruments, and their pricing follows a completely different part of the yield curve.

The 10-year Treasury as the anchor

The 30-year fixed mortgage rate tracks the 10-year US Treasury yield. Investors who buy mortgages are comparing them to the risk-free return of Treasuries. If the 10-year Treasury yields 4.30%, mortgage rates typically sit 2.40 to 3.00 percentage points higher, which would put the average 30-year rate near 6.70 to 7.30%. That gap above the Treasury is called the spread, and it varies based on market conditions. As of April 2026, Freddie Mac’s Primary Mortgage Market Survey puts the average 30-year fixed at 6.85%.

Mortgage-backed securities and the secondary market

When a lender makes you a mortgage, it rarely holds the loan for 30 years. It bundles your loan with thousands of others into a mortgage-backed security (MBS) and sells that bundle to investors, often through Fannie Mae, Freddie Mac, or Ginnie Mae. The price investors are willing to pay for MBS determines how much lenders can afford to charge on new loans. When MBS demand drops, lenders need higher rates to make originating mortgages economically worthwhile. This is why rates can move sharply even when the Fed does nothing.

The Fed does influence rates indirectly. When it raises the federal funds rate, bond markets typically reprice, the 10-year Treasury yield moves, and mortgage rates follow. The Fed also directly bought MBS during quantitative easing periods, which pushed rates down. When it stopped buying (quantitative tightening), spreads widened and rates rose. Understanding this chain helps you see rate moves coming rather than being surprised by them.

Conventional vs FHA vs VA vs jumbo

Not all mortgages are the same product. The type of loan you use determines your down payment requirements, insurance obligations, and often the rate you can get.

Conventional loans

Conventional loans are not government-backed. They follow guidelines set by Fannie Mae and Freddie Mac (the conforming loan limit for 2026 is $806,500 in most US counties). They require at least 3% down for some programs or 5% typically, and private mortgage insurance (PMI) if you put down less than 20%. PMI costs 0.5 to 1.5% of the loan amount per year and disappears once your equity hits 20%.

FHA loans

Backed by the Federal Housing Administration, FHA loans accept lower FICO scores (as low as 580 with 3.5% down) and are popular with first-time buyers. The trade-off: you pay a 1.75% upfront mortgage insurance premium (MIP) plus 0.55% annually. Unlike PMI, MIP on FHA loans stays for the life of the loan if you put less than 10% down. On a $400,000 loan, that upfront MIP is $7,000 rolled into the loan balance.

VA loans

Guaranteed by the Department of Veterans Affairs for eligible service members, veterans, and surviving spouses, VA loans require zero down payment and have no PMI. Rates are typically competitive with or below conventional rates. The only cost is a VA funding fee (1.25 to 3.3% of the loan, depending on down payment and service history) that can be rolled into the loan. For eligible borrowers, VA loans are almost always the best deal available.

Jumbo loans

Loans above the conforming limit are jumbo loans. Because they cannot be sold to Fannie or Freddie, lenders hold them on their own books, which means stricter underwriting: typically a 720 or higher FICO, 10 to 20% down, and proof of substantial liquid reserves. Jumbo rates are sometimes lower than conforming rates when banks aggressively pursue high-net-worth borrowers, but underwriting requirements are harder to meet.

What affects your rate: FICO, LTV, term, and points

The advertised rate is a benchmark, not your rate. Lenders adjust the base rate up or down based on several borrower-specific factors using a pricing grid.

Credit score (FICO)

Your FICO score is the single biggest pricing variable. Lenders use the middle of your three bureau scores. A 760 or higher typically gets the best tier. At 680, you might pay 0.50 to 0.75 percentage points more. On a $400,000 loan, 0.50% more in rate adds roughly $125 per month, or $45,000 over 30 years. Cleaning up your credit report before applying is worth the time.

Loan-to-value ratio (LTV)

LTV is your loan amount divided by the appraised home value. If you buy a $500,000 home and put 20% down ($100,000), your LTV is 80%. Lenders prefer lower LTVs because there is more equity cushion if you default. LTVs above 80% trigger PMI. LTVs above 95% trigger pricing add-ons on top of PMI.

Loan term

A 15-year fixed mortgage carries a lower rate than a 30-year fixed. As of April 2026, Freddie Mac shows 15-year rates averaging about 6.05%, versus 6.85% for 30 years. The monthly payment is higher on the 15-year, but total interest paid is dramatically less. On a $400,000 loan, the 15-year saves roughly $190,000 in interest over the life of the loan compared to the 30-year.

Discount points

One point equals 1% of the loan amount paid upfront at closing to permanently buy down the interest rate. On a $400,000 loan, one point costs $4,000 and typically lowers the rate by 0.25 percentage points. Whether buying points makes sense depends on your break-even timeline: divide the point cost by your monthly savings to find the number of months until you come out ahead. If you plan to sell or refinance within that window, buying points is a losing trade.

Locking your rate

A rate lock is a lender commitment to hold a specific interest rate for a set period, typically 30, 45, or 60 days, while your loan processes. Without a lock, your rate floats with market conditions. If rates rise 0.25% between your application and closing, you pay more every month for 30 years.

Lock periods cost money: longer locks carry slightly higher rates because the lender bears more market risk. A 60-day lock is typically 0.125 to 0.25 percentage points more than a 30-day lock. If your closing is delayed beyond the lock expiration, you may pay an extension fee (usually 0.125 to 0.25% per 7-day extension) or risk losing the rate.

Float-down options

Some lenders offer a float-down provision that lets you capture a lower rate if rates drop significantly after you lock, usually requiring a 0.25 to 0.50 percentage point drop. The option costs extra, often 0.25 to 0.50 points upfront, and the terms vary widely between lenders. In a falling-rate environment, it can be worth it. Get the float-down terms in writing: the definition of “significantly” matters.

Closing costs anatomy

Closing costs are the fees you pay to complete the transaction. On a $400,000 home, expect $8,000 to $14,000 in closing costs, typically 2 to 3.5% of the purchase price. They show up on your Loan Estimate within three business days of your application, and again on the Closing Disclosure three days before closing (required by CFPB rules under TRID). The two documents should match closely.

Here is what the major line items are:

• 01
  Origination fee: What the lender charges to process the loan. Can be a flat fee ($500 to $1,500) or a percentage (0.5 to 1.0%). Some lenders advertise no origination fee but roll the cost into a higher rate instead.
• 02
  Appraisal fee: $500 to $900 for a licensed appraiser to confirm the home’s market value. The lender orders it; you pay it. Non-negotiable.
• 03
  Title insurance: Two policies: lender’s title insurance (required, protects the lender if someone challenges ownership) and owner’s title insurance (optional but recommended). Together these cost $1,000 to $2,500 depending on the state.
• 04
  Prepaid items: Prepaid homeowner’s insurance, property taxes into escrow, and prepaid interest covering the days between closing and the end of the month. These are not lender fees but are still cash out of pocket at closing.
• 05
  Recording fees: Government fees to record the deed and mortgage in public records. $50 to $250 depending on the county.

You can shop for some services on the Loan Estimate, including title insurance, settlement agents, and pest inspections. Shopping those line items can save $500 to $1,500. Lender fees are harder to negotiate but not impossible: if you have a competing offer, use it.
