For Arizona Move-Up Buyers

Qualify for your next home without selling first.

If your current mortgage payment is preventing you from qualifying for the next home, a Guaranteed Backup Contract may allow you to move forward — without selling first.

You stay in control of the sale.

  • Use your own Realtor
  • List at your chosen price
  • Accept any stronger offer that comes in
  • Keep all proceeds above the backup price
  • The backup only triggers if your home doesn't sell in 180 days

How it works, in plain English

  • The problem: your current housing payment pushes your debt ratios above what the new mortgage program will allow.
  • The solution: a Guaranteed Backup Contract from a vetted institutional third-party buyer is a written, non-contingent offer to purchase your current home.
  • The effect: because the backup offer exists, many mortgage programs allow your current house payment to be excluded during qualification, so you can buy the next home.
  • You still: pick your own real-estate agent, list at your price, accept any offer above the backup price, and keep the difference.
  • The backup only triggers if: 180 days pass without an open-market sale.

How it works, step by step

  1. 1

    Receive a guaranteed backup offer on your current home

    A vetted institutional third-party buyer issues a written, non-contingent offer to purchase your current home at a guaranteed price.

  2. 2

    Qualify for the new home without counting your current payment

    With the backup contract in place, many mortgage programs allow your current house payment to be excluded during qualification. You can now qualify for the next home.

  3. 3

    Buy the next home before selling

    You make a strong, non-contingent offer and close on your next Arizona home — without waiting for the current one to sell.

  4. 4

    Sell your old home normally — and keep the upside

    You list with the agent of your choice at your price. You keep all proceeds above the backup price. The backup only triggers if your home doesn't sell on the open market within 180 days.

Hypothetical example

Example scenario

A homeowner in Gilbert wants to buy a new home in Scottsdale. Their income supports the new payment, but qualifying with two mortgage payments on paper pushes them over the program's debt limit.

The Guaranteed Backup Contract lets the current house payment be excluded during qualification. They qualify for the next home, close, move in, and then list their Gilbert home normally on the open market — keeping any sale proceeds above the backup price.

Hypothetical example for illustration only. Actual outcomes vary based on individual financial profile, property value, market conditions, and program qualification. Not a commitment to lend.

Backup contract pricing (GBC fee tiers)

Cost is tiered by the guaranteed offer price on your current home.

Guaranteed price up to Fee
$500,000$2,500
$750,000$3,500
$1,000,000$5,000
$1,500,000$7,500
$2,000,000$10,000
> $2,000,000Reviewed on exception

In some cases, reducing the guaranteed offer amount can lower the program cost while still accomplishing the qualification goal — we'll walk through both options in the consult.

Compare against national alternatives. Many "buy before sell" programs charge 2–3% of the home's value, which can mean tens of thousands of dollars in fees on a typical Arizona move-up sale. Our Guaranteed Backup Contract is a transparent flat fee starting at $2,500. The math is meaningful at every price point.

Comparison reflects publicly published fee structures from competing national "buy before you sell" programs. Each provider's pricing varies; verify current pricing with each provider before deciding.

Eligible loan programs

The backup contract works with most major loan programs that allow the current house payment to be excluded during qualification when a non-contingent backup offer exists.

Who this is for

This is commonly used by:

  • Homeowners upgrading to a larger home
  • Buyers who found the next home before listing theirs
  • Families relocating within Arizona
  • Buyers losing out because of contingent offers
  • Homeowners with strong income who get blocked on qualification
  • Buyers competing in Scottsdale, Chandler, Gilbert, Paradise Valley, Queen Creek, and Phoenix
  • Buyers who want to move on their timeline, not their buyer's
  • Anyone tired of asking permission to make a clean offer

Selling the home — what stays in your control

  • Your listing agent. You pick. The backup contract is financing, not a referral.
  • Your list price. You and your agent set strategy.
  • Your timeline within 180 days. You can accept any open-market offer above the backup price and pocket the difference.
  • Cancellation. When the home sells on the open market, the backup contract is canceled.

What happens if it doesn't sell in 180 days?

The backup buyer purchases the property at the guaranteed price agreed up front. They then handle any necessary repairs and resell it. Net sale proceeds above transaction and repair costs are returned to the seller.

This program works best for homes that are realistically marketable within the 180-day timeframe — we'll help you evaluate that honestly during the consultation.

Backup contract FAQ

Will the backup buyer actually buy my home, or is this just paperwork?

It's a real, written, non-contingent contract from a vetted institutional third-party buyer. If 180 days pass without an open-market sale, they close at the guaranteed price. That's exactly why mortgage underwriting accepts it. The program also includes an equity pledge to protect homeowners — ask about it in the initial consult for details.

Why doesn't this work with FHA?

FHA guidelines do not allow the same current-house-payment exclusion that conventional, VA, jumbo, and Non-QM allow with a non-contingent backup. We can talk through alternatives.

What about HELOCs on my current home?

The backup offer must exceed the outstanding lines on the property, including a HELOC limit, regardless of how much you've drawn. We size the offer accordingly.

Do I get to keep any sale upside?

Yes. If you sell on the open market for more than the backup price, you keep the entire difference. Most clients sell on the open market.

Can I combine this with a bridge loan?

Yes. If you're also blocked on down-payment cash, pairing the backup contract with our in-house bridge loan covers both roadblocks at once — cash for the new down payment, plus qualification relief because the backup lets your current payment be excluded.

Does my real-estate agent get cut out?

No. Your agent lists, markets, negotiates, and closes the home as normal. The backup contract sits behind their effort.
