How much would the Brady Bunch house cost today?
The famous Studio City split-level from The Brady Bunch would realistically cost around $5.5 million in today's Los Angeles market. Assuming a 20% down payment of $1.1 million and a standard 30-year fixed loan at today's 6.69% interest rate, the principal and interest payment alone comes out to approximately $28,348 per month.
That figure doesn't even account for California property taxes or home insurance, which easily push the total monthly housing budget past $34,000. While Mike Brady was a successful architect, housing six kids and a live-in housekeeper in prime San Fernando Valley real estate was a lot easier on a single 1970s income than it would be today. The original 1959-built home featured roughly 2,500 square feet, which meant nine people were squeezed into four bedrooms and a single shared kids' bathroom.
How could Mike Brady finance adding space for six kids today?
To add a bedroom and extra bathroom today, a homeowner in that house would likely turn to a cash-out refinance or a home equity line of credit (HELOC) to leverage built-up equity. Borrowing $200,000 for a major addition at today's 6.69% rate adds roughly $1,289 to the monthly principal and interest payment over 30 years.
In real life, tapping equity means converting built-up paper wealth into usable cash for contractors and materials. If you own a home that has appreciated significantly, financing choices generally fall into three main paths:
- A cash-out refinance replaces your existing primary mortgage with a completely new, larger loan balance.
- A HELOC acts like a second credit line against your home, letting you borrow funds incrementally as construction bills arrive.
- A home equity loan provides a lump-sum payout with a fixed monthly payment, keeping your original primary mortgage untouched.
If you're sketching out your own layout changes at a wood drafting board (paid link), calculating the financing costs up front is the single best way to avoid project scope creep.
Is a cash-out refinance or HELOC better for home renovations?
A HELOC is usually preferable if you already hold a low primary mortgage rate, because a cash-out refinance forces you to reset your entire primary balance to today's 6.69% market rate. Choosing between the two comes down to whether you want to touch your existing underlying loan terms.
If a family locked in a 3% mortgage rate back in 2021, replacing that entire balance with a 6.69% cash-out refinance would dramatically increase overall interest costs. A HELOC allows you to keep that sub-3% baseline mortgage intact while taking out a separate, smaller line of credit specifically for contractor invoices. You only pay interest on the exact amount drawn, which fits multi-stage construction far better than a lump-sum refinance.
