10 Reasons It’s So Hard To Buy A House Right Now

The Main Line Marketplace

Any prospective home buyer looking to buy a house on the Main Line or other Philadelphia suburbs knows how competitive the market is. There are a lot of theories about why. In reality, several reasons exist that have caused the current situation. :

1. Extremely Low Housing Inventory

There are simply not enough homes for sale relative to the number of people who want to buy them. Why?

The “Seller’s Trap”: Owners Won’t List Because They Have Nowhere to Go

Low inventory feeds on itself. Homeowners who would normally sell their starter home and “move up” hesitate to list because they fear they won’t be able to find a new home. By staying put, they further reduce the already tight supply.

The Mortgage Rate Lock-In Effect

Millions of homeowners refinanced or purchased homes during the ultra-low interest rate period (roughly 2020–2022) when rates were often 2.5–3.5%. Moving today could mean financing at 6–7% or more, which could double their monthly payment even if their new house is worth marginally more than their current one. Many owners don’t see enough benefit to justify the massive increase, so they stay where they are.

2. Supply Shortage Effects

When too many buyers are in the market for too few homes, prices rise. The limited inventory also leads to multiple offers, bidding wars, waived mortgage and inspection contingencies, and all-cash offers, making it harder for the typical buyer using financing to compete.

3. The Growing Gap Between Income and Home Prices

About 30-40 years, a typical home cost roughly 2–2.5× the median household income. Today, in our market the ratio is 4× income or higher. Wages have not kept pace with housing appreciation, so even buyers with stable incomes struggle to qualify for mortgages or accumulate down payments.

4. Higher Mortgage Interest Rates

Mortgage rates dramatically affect affordability. Even if home prices stay the same, higher rates increase monthly payments. For example, a buyer borrowing at 3% vs. 6% faces hundreds or even thousands more per month, reducing purchasing power.

5. Student Loan Debt and Consumer Debt

Many younger buyers carry significant student loan balances or other debt. Higher debt levels can:

• reduce mortgage qualification amounts
• make saving for a down payment harder
• increase debt-to-income ratios

6. Rising Insurance and Property Tax Costs

In some areas, property taxes and homeowners’ insurance have risen sharply. With the increase in climate-related damages, insurance costs are expected to continue to rise. Lenders factor these into monthly payments, so buyers may qualify for smaller loans than expected, limiting what they can purchase.

7. Demographic Demand From Millennials

The largest generation in U.S. history—the millennials—is currently in prime home-buying age. (Side note: due to the recent spike in cost and competition for homes the average age of first time homebuyers has risen steeply to an all-time high of around 40 years old.) A large wave of buyers entering the market simultaneously increases demand and intensifies competition for the limited supply.

8. Larger Down Payment Requirements Relative to Savings

Even when buyers can afford the monthly payment, many struggle to accumulate the tens or hundreds of thousands of dollars required for down payments and closing costs, particularly in high-price markets.

9. Appraisal and Lending Constraints

In rapidly rising markets, appraisals sometimes come in below the contract price. When that happens, buyers must bring additional cash to closing, which many cannot do.

10. Rising Construction Costs

Nationally, after the 2008 housing crash, many builders went bankrupt or dramatically reduced construction. The U.S. has been underbuilding housing for more than a decade, creating a cumulative shortage estimated in the millions of homes. Additionally, where there might be land to build on, these increased costs discourage builders from constructing lower-priced starter homes, (due to lower margins) which are often the segment most needed.

This point doesn’t pertain as much in our area as in places where there tends to be a lot of new construction (where there’s more available land). That lack of land to build on, though, means that the Main Line area is not going to see many additional homes built. Increasing demand with no additional total supply only increases competition for the limited houses that exist.

Finally, the rising costs of construction (materials, labor, permit costs, trucking expenses, etc.) does affect the cost of renovations, which are often desired here where the housing stock is older.
