Why Waiting Could Cost You: The Case for Buying a Multi-Generational Home Now

By Angela Shopper · Updated August 2026

The real cost of waiting

When households wait to combine under one roof, they usually keep paying for two of everything — two rents or mortgages, two sets of utilities, two households’ worth of overhead — while building equity in neither. Meanwhile, home prices and rents in the metro have generally trended upward over time. Waiting for a ‘perfect moment’ often just means paying more overhead for longer.

None of this is a reason to buy something you can’t afford. It’s a reason to run the actual comparison — the cost of combining now versus the cost of waiting — instead of assuming waiting is the safe choice.

Multi-gen changes the affordability math

Combining incomes into a single mortgage spreads housing costs across more earners, which often makes a larger, better-located home affordable that none of the households could manage alone. Shared living also spreads the cost of childcare or eldercare that households might otherwise pay for separately.

Don’t let rates freeze you

Mortgage rates move, and no one can time them. The practical principle: you buy the home, but you marry the payment only until you refinance. If rates fall later, refinancing is a straightforward conversation. What you can’t do is go back and un-pay years of rent. Decide on the real payment today, not on a forecast.
