Mortgage Business: A Giant Industry Overview

The mortgage industry is a major financial sector in the United States, with the federal government creating programs to encourage mortgage lending, construction, and home ownership. In recent years, the industry has seen a significant shift towards outsourcing and the increased use of technology, with digital-first subservicers gaining traction. The COVID-19 pandemic also had a notable impact, with low-interest rates leading to a surge in home buying and refinancing. The average purchase price for a home in the US as of Q4 2024 was $510,300, and the average interest rate for a 30-year fixed-rate mortgage in 2024 was 6.73%. The largest mortgage company in the US is United Wholesale Mortgage, which originated 294,387 mortgages worth $108 billion in 2023. The mortgage industry in the US is expected to continue to grow, with a forecast of over $2.5 trillion in originations for each of the next three years.

The mortgage industry is a major financial sector

Mortgage lending is a significant source of finance in the United States, with guidelines designed to satisfy investors and mortgage insurers. Mortgages are debt securities that can be freely conveyed and assigned to other holders. Securitization has grown rapidly in the last decade due to the wider dissemination of technology in mortgage lending. This has led to an increased amount of lending, contributing to the United States housing bubble of 2000-2006. The growth of lightly regulated derivative instruments based on mortgage-backed securities, such as collateralized debt obligations and credit default swaps, was a major factor in this bubble.

The mortgage industry in the United States is vast, with various lenders and brokers offering hundreds of options for mortgages. These include credit unions, banks, mortgage-specific lenders, online-only lenders, and mortgage brokers. The largest mortgage company, United Wholesale Mortgage, originated 294,387 mortgages worth $108 billion in 2023. Other major players include Rocket Mortgage, Fairway Independent Mortgage, U.S. Bank Mortgage, and Navy Federal Credit Union Mortgage.

While the mortgage industry provides numerous benefits to individuals and businesses, such as enabling the purchase of real estate without full upfront payment, there are also concerns. Predatory mortgage lending is an issue, with lenders and brokers finding legal loopholes to obtain additional profit, often at the expense of ill-informed borrowers. The subprime mortgage crisis, characterized by a rise in delinquencies and foreclosures, was one of the first indicators of the 2007-2010 financial crisis. This crisis led to a significant increase in foreclosures and highlighted the risks associated with unsound mortgage lending practices.

Mortgage rates and interest rates

The mortgage industry is a major financial sector in the United States. The federal government has created several programs, or government-sponsored entities, to foster mortgage lending, construction, and home ownership. These include the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), and the Federal Home Loan Mortgage Corporation (Freddie Mac).

Mortgage rates refer to the interest rate a borrower pays on their mortgage loan. The interest rate depends on several factors, including the borrower's credit score, the loan-to-value (LTV) ratio, and the debt-to-income (DTI) ratio. The LTV ratio is the amount borrowed compared to the property's appraised value, while the DTI ratio is the borrower's total debt payments, including mortgage payments, compared to their income. Generally, a lower LTV ratio and a higher DTI ratio lead to higher interest rates.

Interest rates on mortgages can change daily or even multiple times a day, influenced by various economic indicators in the financial markets. Lenders may offer an interest rate lock option, allowing borrowers to lock in a specific rate for a set period. This protects borrowers from potential rate increases during the lock period but may also result in paying a higher rate if rates subsequently decrease.

Mortgage rates in the United States have been volatile in recent years. In 2021, mortgage originations totalled $4.51 trillion, the highest annual volume on record, due to historically low interest rates. However, as rates rose, originations dropped to $2.75 trillion in 2022 and $1.50 trillion in 2023. In 2024, mortgage originations rose to $1.69 trillion, with the average interest rate for a 30-year fixed-rate mortgage at 6.73%. As of March 31, 2025, the average interest rate for a 30-year fixed mortgage ranged from 6.75% to 6.80%.

Mortgage debt and delinquency

Mortgage lending is a major sector of finance in the United States, and the federal government has created programs to foster mortgage lending, construction, and home ownership. These programs include the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae), and the Federal Home Loan Mortgage Corporation (Freddie Mac). These programs work by offering guarantees on mortgage payments for certain conforming loans, which are then securitized and issued to investors as mortgage-backed securities (MBS). Securitization has grown rapidly in the last decade due to the wider dissemination of technology in the mortgage lending world, allowing for more rapid capital outflow from investors to borrowers.

However, there are concerns about predatory mortgage lending in the United States, where lenders and brokers may be exploiting loopholes in the law to obtain additional profit. This typically involves offering loans with terms beyond the borrower's means, leading to default and the lender taking possession of the property. The growth of lightly regulated derivative instruments based on mortgage-backed securities, such as collateralized debt obligations and credit default swaps, was a major cause of the United States housing bubble of 2000-2006 and the subprime mortgage crisis of 2007-2010.

Mortgage delinquencies have been increasing in recent years, with the total delinquency rate for all loans outstanding increasing in the fourth quarter of 2024. The delinquency rate for mortgage loans on one-to-four-unit residential properties increased to a seasonally adjusted rate of 3.98% of all loans outstanding at the end of the fourth quarter of 2024, according to the Mortgage Bankers Association (MBA). The delinquency rate was up 6 basis points from the third quarter and up 10 basis points from the previous year. The percentage of loans on which foreclosure actions were started in the fourth quarter rose by 1 basis point to 0.15%. The five states with the largest quarterly increases in their overall delinquency rate were Florida, South Carolina, North Carolina, Georgia, and Louisiana.

The 30-89 mortgage delinquency rate is a measure of early-stage delinquencies and can be an early indicator of the mortgage market's overall health. It captures borrowers who have missed one or two payments.

Mortgage lenders and refinancing

The mortgage industry in the United States is a major financial sector. Mortgage lending is a significant part of the industry, with the federal government creating various programs to encourage mortgage lending, construction, and home ownership. These programs include the Government National Mortgage Association (Ginnie Mae) and the Federal National Mortgage Association (Fannie Mae).

Mortgage refinancing is a common practice, where individuals replace their existing home loans with new ones, often to obtain better terms or interest rates. The process typically involves the same steps as applying for an initial mortgage, and it usually takes around 1-2 months to complete. Refinancing can help lower monthly payments, change the loan term, or provide access to cash through a larger home loan.

When considering refinancing, it is essential to compare multiple lenders to find the best option. Lenders may offer different interest rates, fees, and loan types, so shopping around can help individuals find the most suitable deal. Additionally, refinancing to a fixed-rate loan from an adjustable-rate mortgage is a common strategy to reduce monthly payments.

Several institutions in the United States offer mortgage refinancing options. These include Bank of America, which provides information on refinancing and adjustable-rate mortgages. JP Mortgage Chase is another option, offering a combination of online resources, articles, and daily updated rates, earning it the best online mortgage experience award. Other lenders with favourable reviews for refinancing include Rocket Mortgage, First Federal Bank Mortgage Lenders, Rate, Better, U.S. Bank, Citi, Fairway Independent Mortgage Corp., and LendingTree.

While refinancing can provide benefits, it is important to carefully consider the costs and potential risks. Refinancing may come with higher fees, and a lower refinance rate may not always be the most cost-effective option. It is crucial to understand the Annual Percentage Rate (APR), which reflects the full cost of a loan, including fees and interest.

Mortgage-backed securities

MBS are asset-backed securities formed by pooling together mortgages. MBS are created by bundling together many mortgages and selling shares of the resulting pool to investors. This process is known as securitization. MBS can be issued by government-sponsored entities (GSEs) like Fannie Mae, Freddie Mac, and Ginnie Mae, and are considered to be of the highest credit, given government backing. Non-agency MBS are issued by private entities and carry higher risk and potentially higher yields since they are not government-guaranteed. MBS can offer regular income through interest and principal payments, portfolio diversification, and potentially higher yields than other fixed-income securities.

MBS are debt securities and can be conveyed and assigned freely to other holders. MBS are debt obligations that represent claims to the cash flows from pools of mortgage loans, most commonly on residential property. MBS are also known as "agency paper" or "agency bonds". MBS must be issued by a GSE or a private financial company, and the MBS must have received one of the top two ratings from an accredited credit rating agency.

MBS exhibit a variety of structures. The most basic types are pass-through participation certificates, which entitle the holder to a pro-rata share of all principal and interest payments made on the pool of mortgage loans. More complicated MBS, known as collateralized mortgage obligations (CMOs) or real estate mortgage investment conduits (REMICs), consist of multiple classes of securities designed to appeal to investors with different investment objectives and risk tolerances.
