Thinking about moving up in Boise? Your next house could cost more than you think

The true cost of selling your home and buying another in Boise, Meridian and the Treasure Valley.

There’s a conversation more homeowners should be having before they decide to move.

Not just, “How much can I sell my house for?” or “What can I afford to buy?”

But “How much is this move actually going to cost me, and is it worth it?”

Those are two very different questions.

If you’ve owned your home for several years, there’s a good chance you’ve built up some equity. Maybe your family has outgrown the house. Maybe you want a shorter commute, a bigger yard, or a different neighborhood.

All perfectly good reasons to move.

But there’s a financial side to that decision that often gets overlooked, especially by homeowners who purchased or refinanced when mortgage rates were much lower.

That 3% mortgage might be worth more than you realize

Let’s say you bought your home a few years ago and locked in a mortgage rate around 3%.

Now you’re looking at a larger home in Meridian, Eagle, or Southeast Boise.

You might have $200,000 or more in equity to put toward the next purchase. On paper, that sounds like you’re in great shape.

But you may also be trading your 3% rate for one that’s more than twice as high.

Here’s what that looks like on a $400,000 loan (principal and interest only, 30-year fixed):

That’s roughly $1,110 more every month for the same loan amount. And if the new house also means borrowing more, the gap gets wider.

These figures are illustrative. Your actual rate and payment will depend on the market, your credit, and your loan terms.

The bigger house might be worth it. But it’s important to understand exactly what you’re giving up.

Your existing mortgage isn’t just a monthly bill. If you’ve locked in a particularly low rate, it’s also a financial advantage that’s difficult to replace.

Selling your house isn’t free. Neither is buying the next one.

Most homeowners have a pretty good idea of what their house is worth and approximately how much equity they have.

What often gets overlooked is how much of that equity gets consumed during the move.

Consider a hypothetical homeowner selling a $550,000 house. They might have expenses like:

That’s $60,500 before considering any additional financing costs over time.

Those numbers are illustrative, not a standard fee schedule. Actual costs depend on the property, negotiations, financing, and how complicated the move becomes.

And to be clear, your down payment isn’t an expense in the same way. That’s equity you’re transferring into another property.

But the money spent on fees, moving, and closing costs is money you generally don’t get back.

One more thing worth asking about: depending on how long you’ve owned your home and how much it has appreciated, selling could have tax implications. A quick conversation with a tax professional before you list can save surprises later.

The monthly payment is only part of the story

Here’s another thing to think about.

Let’s say your current home costs $3,500 per month when you include your mortgage, property taxes, insurance, utilities, and an allowance for maintenance.

The next house costs $4,800.

That’s an additional $1,300 every month.

Over five years, that’s $78,000 in additional cash outflow before accounting for future cost changes.

Now add the upfront costs of moving.

Suddenly, that move looks quite a bit different financially.

Of course, you’re also building equity in the new home, and its value may increase. That’s why simply adding up the payments doesn’t tell the entire story.

But neither does looking only at the equity you’ll have when you sell.

You need to consider both.

What if you stayed and invested the difference?

This is the part I find particularly interesting.

We tend to assume that moving into a more expensive house is a way to build more wealth.

Sometimes it is.

But what if you stayed in your current house and invested the money you would have spent moving? And what if you also invested the difference between your current monthly housing costs and the costs of the new house?

This is a simplified illustration. It doesn’t account for taxes, and it doesn’t subtract the equity you’d be building in the new home. Investment returns aren’t guaranteed, and a financial advisor can help you think through what makes sense for your situation.

The point isn’t the exact number. It’s that the money you don’t spend on a move has its own potential to grow.

And there’s another consideration: owning a more expensive house doesn’t guarantee that it will appreciate faster.

A $750,000 home isn’t automatically a better investment than a $550,000 home.

It depends on the market, the neighborhood, the purchase price, and what happens over the years you own it.

That’s why homeowners should compare both scenarios rather than automatically assuming the more expensive house is the better financial move. The True Cost of Moving Calculator lets you run this comparison with your own numbers.

But here’s where the numbers don’t tell the whole story

I don’t want to make the argument that everyone should stay in their current home just because they have a low mortgage rate.

That’s not realistic.

Maybe you’re spending an hour commuting each way and missing time with your kids.

Maybe your family needs another bedroom.

Maybe you want to be closer to aging parents, or you’ve simply decided you’d enjoy living somewhere else.

Those things have real value.

When we moved from Portland to the Treasure Valley, we learned how much the location of your home can affect everyday life. Commutes, activities, and the amount of time you spend driving around all matter. (It’s why I put together a commute cost map.)

Sometimes paying more for a house that fits your life better is absolutely worth it.

The point isn’t that moving is a bad financial decision. It’s that you should know what you’re paying for that better lifestyle.

Should you sell your house and buy a bigger one? Run the numbers first.

I wanted a way for homeowners in Boise, Meridian, Kuna, Eagle, and the rest of the Treasure Valley to see the entire financial picture before deciding to move.

So I built a calculator that goes beyond simply estimating a new mortgage payment. It looks at:

• What you’ll actually walk away with after selling your current home
• How much cash you’ll need to purchase the next house
• Selling expenses, closing costs, moving expenses, and temporary housing
• How your monthly housing costs will change
• The financial impact of giving up your existing mortgage rate
• How much cash you’ll have left after moving
• Whether staying or moving could leave you better off financially over time

You can adjust the assumptions to reflect your own situation, including home appreciation, investment returns, and how long you expect to stay.

It’s not a crystal ball, and it doesn’t replace a lender’s loan estimate or an actual seller net sheet.

But it can help you understand the tradeoffs before you make a decision involving hundreds of thousands of dollars.

My advice? Run the numbers before you start looking at houses.

It’s easy to fall in love with a house.

And once you start imagining your family living there, it’s easy to justify the additional expense.

I’d rather see homeowners understand the financial impact before they get emotionally invested in the next property.

Maybe the numbers show that moving makes perfect sense.

Maybe they show that waiting another year or two would put you in a better position.

Or maybe you decide the lifestyle improvement is worth the additional cost, even if staying would leave you with more money.

Any of those can be the right decision.

A good real estate decision isn’t always the one that makes you the most money. But it should be one you make with your eyes open.
