Can I buy the next one before I sell this one?
The math behind the move-up. Run your current home, your target home, and your cash position. See the overlap gap, the strategies that close it, and whether the timing actually works for you.
Your numbers, both sides
Your Current Home
What you think it would sell for. A real valuation tightens this number.
From your most recent statement.
Just P&I, not the escrowed taxes or insurance.
Property tax (monthly), insurance, HOA, baseline utilities.
Cedar City currently averages 78 to 104 days. St. George varies by price point. Start at 60 and slide up for a stress test.
Your Next Home
Your buying range, not a wish.
Defaults to current. Override with your locked rate if you have one.
5% minimum conventional, 3.5% FHA. 20% avoids PMI.
Exact dollar amount you plan to put down.
Auto-calculated. Edit if you have a locked quote.
Property tax, insurance, HOA, utilities on the new home.
Your Cash & Liquidity
This is the section that decides it. The math on the homes is straightforward. The variable that makes or breaks a buy-before-you-sell is how much cash you can move without selling first.
Liquid cash, not from current home equity. Savings, checking, money market.
Investments or assets you’d use temporarily and replenish at sale.
If you don’t have one, you generally can’t open one once your home is listed. Worth knowing before you list.
The unused portion of your line that you could draw on right now.
Your cash position covers the overlap with real cushion. Buying before selling is on the table.
Most lenders won’t approve a new HELOC once your current home is listed for sale. If a HELOC is part of your plan, set it up first, then list. Talk to me before you call the credit union, so the timing works on both sides.
The overlap math, line by line
The post-sale picture
The overlap is temporary. Here’s what your position looks like once the current home closes and the dust settles.
Sale price minus payoff minus estimated selling costs (commission, title, escrow, prorations).
Any HELOC balance drawn during the overlap gets paid off from sale proceeds at closing.
Sale proceeds minus HELOC payoff minus the cash you used during the overlap. This is what hits your account once the second closing wraps.
Next home P&I plus carrying costs. The old payment is gone. This is what you actually live with.
Bridge strategy comparison
If your cash on hand doesn’t cover the overlap, these are the three tools that do. Each has tradeoffs. The card with the blue ring is the best fit for your numbers.
HELOC on Current Home
Tap your current home’s equity through a line of credit. Cheapest option, but you have to set it up before listing.
Bridge Loan
Short-term loan against current home equity, designed for this exact gap. Costs more than a HELOC, harder to qualify for, but works after listing.
Recast or Delayed Financing
Put a lot of cash down up front, then pull it back out via cash-out refi or recast after your current home sells.
The strategy depends on your actual home value, not your estimate.
The math above is one piece. The other piece is timing your current home’s listing to support this strategy. That’s where having me as your listing agent on the sale side coordinates with the mortgage process on the purchase side. I can’t be your buyer’s agent if I’m your lender, but I bring in a trusted referral partner so the whole timeline holds together.
How buying before selling actually moves.
The math is the easy part. The choreography is the part that breaks down most often. Here’s what each piece does.
The Overlap Window
The number of days you own both homes. Starts the day you close on the new one. Ends the day you close on the sale of the current one. Every day in between, you’re carrying both mortgages and both sets of carrying costs. Pricing the current home aggressively shortens this window.
Cash vs Equity
Equity in your current home is real, but it’s not available until you sell. The bridge strategies all exist to convert some of that equity into temporary cash. Cash on hand is the cheapest source. HELOCs are next. Bridge loans are the most expensive. Plan around the cheapest source you can qualify for.
Qualifying for Two Mortgages
Lenders look at debt-to-income with both mortgages counted unless you have a signed lease or a fully executed sale contract on the current home. This is the hidden gatekeeper. Even if your cash position is fine, your DTI has to clear. We sort this out in pre-approval before you start touring the next home.
Why the Listing Strategy Matters
A buy-before-you-sell falls apart when the current home sits. Days on market drives every other number in this calculator. Pricing right out of the gate, photos that actually pull buyers, and timing the launch (Cedar City spring market, St. George shoulder seasons) is where the listing agent earns the commission. That’s the side I quarterback.
The Contingent Alternative
If the math says “sell first or wait,” that doesn’t mean you’re stuck. A contingent contract on the new home (subject to your current home selling) is the middle path. Less common in a competitive market, but possible. The other option is a rent-back agreement after you sell, giving you 30 to 60 days to close on the next one.
Cedar City and St. George Specifics
Days on market in Iron and Washington counties run longer than the Wasatch Front. Plan for a 60 to 90 day overlap, not the 21 days you saw a few years ago. Cedar City spring (March through May) and St. George shoulder seasons move faster than midsummer or December. Time the listing to the market, not just to when you find the next home.
