The situation
Tom and Ellen R. came in at 67 and 67. They had raised three kids in their Northbrook colonial, had been there since the early eighties, and the kids had been gone for fifteen years. The house was worth roughly $950K and carrying a Cook County property tax bill of about $19K per year. They had a $2.4M portfolio, no debt, and Tom's modest pension covering most of their fixed expenses.
They weren't in financial trouble. They were in the very common situation of a retired couple living in a five-bedroom house, paying property taxes that had quietly tripled over twenty years, doing more home maintenance than they enjoyed, and quietly wondering whether it still made sense.
The challenge
The hard part of downsizing is rarely financial. It's emotional, social, and logistical. The kids' bedrooms. The garden. The neighbors. The dentist they had used for twenty-five years. They came in willing to talk about money but very nervous that the conversation would push them somewhere they didn't want to go.
We told them at the start: the math is one input. If the math says move and your gut says stay, your gut wins and we will plan around it. They appreciated that, and that opened the room enough to actually run the numbers honestly.
Our approach
We modeled three scenarios in parallel. Scenario one: stay. Continue paying $19K/year in property tax, plan for $25K/year in cumulative maintenance and capital projects (roof in eight years, HVAC in five, the windows nobody had touched), and let the home appreciate at a conservative 2% per year. Net cost of staying over thirty years, after appreciation: roughly $850K of carrying cost.
Scenario two: downsize within Northbrook. A $650K townhouse in a nearby development with $11K property tax. Frees roughly $300K of equity, cuts maintenance, but keeps them inside Cook County's tax assessment dynamics, meaning the savings would partially erode as the new home was reassessed.
Scenario three: cross the line into Lake County. A $580K townhouse in Lake Bluff with $9K property tax. This was the option neither of them had seriously considered. Lake County's assessment ratio runs differently from Cook's, and at the price point we were looking at, the annual savings were materially larger and more durable. The location was twenty-three minutes from their grandchildren in Glenview, same as the current drive, just from a different direction.
We walked through each scenario across thirty years with a real spreadsheet, including reinvestment of the freed equity at a conservative 5% real return, the tax-cost differential, the maintenance differential, and a sensitivity for if either of them needed to fund late-stage care. Scenario three came out about $300K ahead of scenario one over thirty years on a present-value basis.
Then we stopped and asked: does any of this matter to you? They sat with it for two months. They drove up to Lake Bluff three times, walked the neighborhoods, had coffee at the same café twice. Their daughter, the one in Glenview with the grandchildren, drove the route both ways and reported back that it was actually slightly easier than getting through Northbrook traffic.
The outcome
They closed on a $580K townhouse in Lake Bluff last fall. Sold the Northbrook house for $945K. Net of selling costs and the new purchase, they freed approximately $370K of equity, which we deployed into the taxable brokerage portion of their portfolio. Annual property tax dropped by roughly $10K, a savings that compounds in two ways: the immediate cash flow and the $370K of working capital that was previously locked in real estate.
The takeaway
Downsizing is a planning question, not a real-estate question. The numbers depend on which side of which county line you land on, what assessment regime catches the new house, and what you do with the freed equity. The right answer for one Northern Suburbs couple is to stay; for another it's to move ten miles north. Run the actual scenarios, including the emotional ones, and let the numbers inform, not decide, what you do.
