Bridge Loan vs Two Mortgages in New Braunfels

Should you use a bridge loan or carry two mortgages when buying before you sell in New Braunfels?

Neither choice is decided by the interest rate. It's decided by how long your current home takes to sell. If your house sells in about three weeks, the two paths cost roughly the same and you should pick whichever wins you the stronger offer, which is usually the bridge loan. Stretch that timeline to four months and both get expensive fast: a bridge loan at roughly $1,750 a month runs about $7,000 in interest plus upfront fees, while carrying two mortgages on a $450,000 home and a $650,000 purchase puts about $6,200 a month out of pocket the entire time.

You found the next house. You haven't sold the one you're standing in.

That's one of the most expensive decision points in the entire move, and almost nobody runs the actual math before making the call. They fall in love with a listing, pick a financing path because it sounds simpler, and find out three months later what that decision really cost.

We're Drake and Michelle Carter with The Carter Team at Keller Williams Heritage. We walk New Braunfels clients through this exact decision most weeks. Below is the math we put in front of them, the three paths available, and the one variable that actually settles the question.

First, why this matters more now than it did a few years ago.

In 2021 and 2022 this was barely a question. You listed, you had offers by the weekend, and you closed fast. The gap between selling the old place and buying the new one was tiny, so the carrying risk was close to zero.

That market is gone. Across New Braunfels and the Hill Country corridor, homes are taking longer to sell. Buyers have more choices and they're negotiating. A well priced home still moves, but the automatic weekend sale isn't the default anymore. That gap between buying and closing has widened, and wider gaps cost real money.

The setup: $450,000 house, $650,000 purchase, and a cash problem

Here's a clean example so the math stays concrete. These are illustration numbers, not a quote.

Say you own a New Braunfels home worth about $450,000 and you owe $200,000 on it. That's roughly $250,000 in equity sitting in the house, before selling costs.

You've found the next place at $650,000. You want to put 20 percent down, so $130,000 at closing plus your normal closing costs.

Here's the trap. That entire $130,000 down payment is locked inside the house you haven't sold. You can't reach it until that house closes. So how do you buy the new one?

You have three real options.

Path one: the bridge loan

A bridge loan is short term financing that lets you borrow against the equity in your current home and use it as the down payment on the next one. It literally bridges the gap between buying and selling. Drake walks through how it works at 2:23.

In our example, the lender lets you pull $130,000 out of your current home's equity to cover that down payment. You buy the new home now. When the old house sells, you repay the bridge loan in full from the proceeds.

The advantage here is strategic, and it's bigger than most buyers realize. You get to make an offer without a sale contingency. You're not asking a seller to sit and wait on your house in a slower market. A clean, non contingent offer is one of the strongest things you can put on the table. It can win you the home, and it can win you a better price on it.

Now the cost. Bridge loans are not cheap money. The rate is typically higher than a normal mortgage and there are setup fees. Figure somewhere around $1,500 to $2,000 a month in interest while it's open, plus a couple thousand in upfront fees.

Hold onto that monthly number, because this is the key idea: with a bridge loan, your cost is tied directly to how long it stays open. Sell fast and the bridge loan is cheap. Let it drag and the meter keeps running.

Path two: carrying two mortgages

Simpler to understand, heavier on your wallet. You buy the new home with your own cash or a standard loan, keep the old mortgage going, and carry both until the first house sells. We break this path down at 3:45.

This works only if two things are true. You have enough cash on hand for the down payment, and you qualify to carry both loans at once. Plenty of people are in exactly that position, especially longtime owners with deep equity and buyers coming in from a higher cost metro like Austin, Dallas, or Los Angeles. If that's you, our breakdown of the California to New Braunfels property tax math is worth a read before you set your budget.

The numbers on this path:

• Old mortgage payment: about $2,000 a month

• New mortgage with taxes and insurance: about $4,200 a month

• Total while both are open: roughly $6,200 a month out of pocket

The upside is real. You skip the bridge loan fees and the higher bridge rate entirely. The downside is just as real. If the old house sits unsold for months, you're covering that full second payment the whole time, and it adds up fast.

Path three: buy before you sell programs and cash buyers

There's a third lane. Companies will step in and solve the problem for you, for a fee. Michelle covers these at 4:43, and the difference between them matters.

Instant cash buyers, what the industry calls iBuyers, are active in our area. Opendoor is the name most people know. They make a cash offer, you accept, you pick your closing and move out dates, and you're done. No showings, no open houses, no waiting on a buyer's financing, no two payments. The trade off is that the offer is an investor price, so you're giving up some of your sale price in exchange for certainty and speed.

Buy before you sell programs, like the one Homeward runs here, work differently. They unlock a portion of your current home's equity upfront so you can use it as the down payment on the next house, similar to a bridge loan. You buy, you move in, and then your old home goes on the market with your agent, so you're still chasing full market value. If it resells for more, that profit typically comes back to you.

So why doesn't everyone do this? The fees. These are convenience fees, and convenience has a price tag. For a family relocating on a hard deadline, it is absolutely worth it. For someone else, it's an expensive way to solve a problem that a well priced listing would have handled anyway. The numbers vary by program and by home, which is exactly why you run them before you commit.

The mistake almost everyone makes

Here's the part we promised at the top.

When people compare these options, they fixate on the interest rate. They ask what the rate is on the bridge loan and treat that as the whole decision.

That is the wrong question.

The real question is this: how long is your current home going to take to sell? That single variable, your days on market, drives the entire answer. Drake makes the case at 6:19.

Watch what happens at two different timelines.

Three weeks. The bridge loan barely costs you anything. Carrying two mortgages for three weeks is close to nothing either way. At that speed the two paths are basically a tie, so you lean toward whichever gives you the stronger offer, which is usually the bridge.

Four months. Now the bridge loan at roughly $1,750 a month costs you around $7,000 in interest plus fees. And the two mortgage path, at about $6,200 a month in total payments, has you far deeper out of pocket in raw cash flow while you wait, even accounting for the share going to principal.

Do you see what happened there? Neither option got more expensive because of the rate. They got more expensive because the house took longer to sell.

The timeline is the lever. Everything else is a footnote.

How we actually walk clients through the decision

Four steps, in this order. The full walkthrough starts at 7:32.

1. Get an honest estimate of your days on market. Before anything else, we figure out how long your current home will realistically take to sell at the right price. Not your dream price. The right price for today's market. That number is the foundation of the whole decision, and it's why our home sale prep timeline for New Braunfels sellers matters more than most people expect.

2. Look hard at the cash position. Do you have funds to carry two mortgages comfortably through that realistic window, with a cushion on top? If yes, carrying two may save you the bridge fees. If your cash is locked in your current home's equity, the bridge loan is probably your path. A seller net sheet is the fastest way to see what your equity actually frees up after costs.

3. Factor in the strategic value. In a slower market, the ability to make a non contingent offer is worth real money. Sometimes the bridge loan costs a little more on paper but wins you a better deal on the new home, and you come out ahead overall. Sellers are still nervous about accepting contingencies.

4. Build in a margin of safety. We never plan around the best case timeline. We plan around a realistic one, then make sure you can handle it if the sale takes longer than we hope.

Bringing it home

Three paths, three trade offs.

A bridge loan keeps your cash flexible and your offer clean, but the meter runs the longer your old home sits. Carrying two mortgages skips the bridge fees but leans on your cash reserves while you wait. A buy before you sell program hands you certainty, and you pay real money for it.

The thing that decides between them isn't the rate or the fee. It's how long your current home takes to sell. Get that number right and the rest of the decision makes itself. Get it wrong and every path gets expensive.

Before you fall in love with a listing and make a move you can't easily undo, run your real numbers. That's exactly what we do: sit down, look at your actual situation, and build the plan that fits your numbers instead of somebody else's. We can help you with every one of these three options, including the full buy before you sell playbook we've mapped out for New Braunfels.
