What is an assumable mortgage?

An assumable mortgage is an existing home loan a new buyer can take over, subject to lender or servicer approval. You inherit the remaining principal balance, the interest rate, and the remaining term. You do not get a brand-new 30-year clock unless the note is structured that way; you step into the seller’s remaining schedule.

That structure is why assumptions draw so much attention when market rates sit well above rates locked in 2020-2022. You keep the seller’s payment math instead of pricing a new loan at today’s average.

Most government-backed loans (FHA, VA, and many USDA loans) include a qualifying assumption feature. Most conventional loans do not, or they include due-on-sale language that blocks a clean assumption (NAR; Pennymac).

Why assumptions matter in Phoenix right now

As of the week of September 10, 2026, the U.S. average 30-year fixed rate sat at 6.76% (Freddie Mac Primary Mortgage Market Survey). Many Valley sellers who bought or refinanced during the low-rate years still carry notes in the low-to-mid single digits.

Principal & interest example from Veterans United. Taxes, insurance, and HOA are extra.

Phoenix, Peoria, Surprise, Scottsdale, Goodyear, and Buckeye all have inventory where FHA or VA financing sits behind the listing. Public listing aggregators regularly surface hundreds of Phoenix-area homes marketed with assumable financing (for example, Roots Homes Phoenix and Arizona-wide inventories). Those counts change weekly, so treat them as a market signal, not a guarantee of availability.

For buyers relocating into the Valley, military families near Luke AFB, and move-up buyers squeezed by payment shock, an assumption can restore purchasing power without waiting for rates to fall.

Which loans are assumable?

Always verify the specific note and servicer rules. “Government loan” does not auto-approve the deal.

FHA loan assumptions

FHA loans are designed to be assumable when the buyer meets the mortgagee’s credit and underwriting standards. For loans originated on or after December 15, 1989, the buyer must qualify; the lender does not simply rubber-stamp the transfer (Neighbors Bank; FHA.com).

What buyers usually need

• Acceptable credit history and score under the servicer’s guidelines
• Documented income and a workable debt-to-income ratio
• Proof of assets for the equity gap, closing costs, and reserves
• Servicer package completion (assumption application, disclosures, authorizations)

Fees

FHA raised the maximum allowable assumption processing fee a mortgagee may charge. Industry summaries of HUD Handbook updates place the current maximum at $1,800 (up from a long-standing $900 cap) (AssumeList; Sandler LLC; HUD Handbook 4000.1). Actual fees vary by servicer and cannot exceed the HUD maximum.

Appraisals are often not required for a pure assumption, though buyers still order inspections and may order an independent appraisal to validate the equity gap (LendingTree).

VA loan assumptions (including non-Veterans)

VA loans are assumable when the buyer meets the servicer’s requirements. You do not need to be a Veteran to assume a VA loan. That is one of the most common misconceptions in the Valley market (Veterans United).

Buyer side

• Credit, income, assets, and employment verification with the current servicer
• Ability to cover the equity gap
• VA funding fee on assumptions: 0.5% of the loan balance (Veterans who are funding-fee exempt stay exempt on the assumption fee)

Seller / entitlement side

If a non-Veteran (or a Veteran without enough entitlement to substitute) assumes the loan, the selling Veteran’s entitlement often stays tied to that loan until it is paid off. That can limit the seller’s future 0% down VA purchasing power. When another Veteran with sufficient entitlement substitutes, the seller can request a release of liability and entitlement restoration path (VA Buyer’s Guide; Veterans United).

USDA assumptions in the Valley

USDA Rural Development loans can be assumable with approval. In the Phoenix metro, pure USDA-eligible tracts are less common inside dense city limits and more common in outlying or designated rural areas (for example, parts of Pinal County and other edge markets). Confirm property eligibility on the USDA property eligibility map before you chase a USDA assumption as your primary strategy inside Phoenix proper.

The equity gap: how you fund the difference

The equity gap is the difference between the agreed sale price and the remaining loan balance.

You typically fund that gap with:

1. Cash
2. Secondary financing (second mortgage, HELOC-style product, or other gap financing the first-lien servicer allows)
3. A blend of cash plus second financing

Servicers underwrite the full picture. A second lien that spikes your DTI can sink an otherwise clean assumption (Pennymac; Veterans United).

This is where an agent who works assumptions every week earns their keep: structuring offers, sequencing the servicer package, and modeling blended payments so the “low rate” still works after you fund the gap.

Step-by-step: how to assume a mortgage

1. Confirm the loan is truly assumable Ask the listing agent or seller for loan type (FHA/VA/USDA), servicer name, approximate rate, remaining balance, and remaining term. Get it in writing.
2. Run the payment math both ways Compare assumed P&I plus taxes/insurance/HOA against a new-market-rate loan on the same price. Factor the cash needed for the equity gap.
3. Get pre-checked for assumption credit Servicer guidelines differ. A conventional pre-approval letter is useful context, but it is not the assumption underwrite.
4. Write an offer that contemplates assumption timelines Assumptions often take longer than a standard purchase. Consumer reports and buyer forums frequently cite multi-month timelines when servicers move slowly (CFPB; buyer reports). Build realistic contingencies and a clear communication cadence with the seller.
5. Submit the servicer assumption package Credit auth, income docs, asset statements, purchase contract, and program disclosures.
6. Clear the equity gap funding Wire plan, second-lien approval if needed, and title coordination.
7. Close and record Liability transfer, deed, and (for VA) entitlement paperwork if substitution applies.

How to find assumable homes in Phoenix

Public portals rarely make assumptions easy to filter. Many listings never spell out “assumable” in the headline even when the underlying loan allows it (r/RealEstate discussion).

Practical search stack for the Valley

• Work with a local agent who already screens ARMLS for FHA/VA and seller willingness
• Ask every listing agent: loan type, rate, balance, servicer, and whether the seller will entertain an assumption
• Cross-check specialty inventories and education sites (e.g. realtor.com assumable hub, AssumeList)
• Browse HouseSearchAZ.com for fresh MLS inventory, then have Drew flag which homes are realistic assumption candidates

North Phoenix, Peoria, Surprise, Scottsdale, Goodyear, and Buckeye each behave differently on price bands and VA density. Luke AFB-area inventory deserves a dedicated VA screen.

Pros and cons

Creative financing beyond assumptions

Assumptions are one tool. Valley deals also use:

• Seller financing / owner carry
• Hybrid structures (where allowed) plus new money
• Rate buydowns on new financing when no assumable note exists
• Strategic pricing when a seller markets the payment, not only the list price

Drew’s positioning on HouseSearchAZ centers on assumptions and creative financing so buyers are not stuck waiting on a single product type.
