The Real Cost of Staying in a Home Is Becoming the New Affordability Test
For years, buyers have treated the mortgage rate as the defining number in a home purchase. That view is becoming too narrow. The sharper investment question now is not only whether a buyer can acquire the property, but whether the full carrying cost remains sustainable after closing.
A recent Fortune report, citing an Ownwell survey of 2,500 U.S. homeowners, shows how quickly this pressure is building. Some 76% of homeowners said property taxes have been higher than they budgeted for, up 10 percentage points from the prior year. Nearly two-thirds were surprised or shocked by their most recent tax bill, while 40% said they had considered moving because of property taxes.
For investors, landlords, and financially disciplined buyers, this is not a minor household budgeting issue. It is a valuation signal. When taxes, insurance, maintenance, and association fees rise faster than incomes or rents, net operating strength weakens. A property that looks affordable on purchase price can become less attractive once the annual expense line is fully underwritten.
The fixed-rate mortgage still provides stability on the debt side, but it no longer guarantees predictability in total ownership cost. Escrow payments can rise as assessments reset, insurance renewals adjust, and local governments respond to budget pressure. In markets with sharp post-pandemic price gains, assessments are now catching up to prior appreciation.
The strongest buyers are no longer underwriting the purchase price alone. They are underwriting the cost of staying.
The five-year rise in new-home sale prices, roughly 23% according to Federal Reserve data cited in the report, has created a delayed tax effect. Higher values improve household balance sheets on paper, but they also create room for higher assessments. In high-tax states such as New York, Massachusetts, Texas, and parts of the Northeast, that can materially change the monthly affordability equation.
Insurance is the other variable investors can no longer treat as background noise. Fortune notes that average annual home insurance premiums rose 12% in 2025 and are projected to increase again in 2026, with premiums up 46% since 2021. Disaster-exposed markets carry the greatest risk. In Florida, typical premiums are approaching $8,500, while California faces renewed pressure after wildfire losses.
This matters for rental investors because expense inflation can compress yields even when rents are stable. A landlord buying at a 5% or 6% gross yield may find the real return meaningfully lower if taxes, insurance, and maintenance are rising faster than rent growth. In condominium markets, association fees and special assessments add another layer of uncertainty, particularly in older buildings or luxury developments with high service expectations.
Bankrate’s 2025 estimate, also cited in the article, places hidden single-family ownership costs above $21,000 per year nationally, with maintenance alone accounting for $8,808. That number should be treated as a baseline underwriting input, not an afterthought. For buyers moving from renting, it is often the gap between theoretical affordability and lived affordability.
The practical response is straightforward. Before buying, model the property with stressed assumptions: higher taxes, higher insurance, annual maintenance reserves, HOA increases, and a contingency for major repairs. For investors, compare those costs against conservative rent growth, not optimistic appreciation. For homeowners, the same discipline protects lifestyle and liquidity.
The market is sending a clear message. Price and rate still matter, but they are only the entrance cost. Long-term ownership strength now depends on whether the recurring expenses can be absorbed without eroding cash flow, savings, or the reason the property was attractive in the first place.
