Refinancing, ARMs & Mortgages

Know Your Options

Fixed Rate vs. Adjustable Rate

The most important decision in mortgage strategy. Your choice depends on timeline, risk tolerance, and rate outlook.

30-Year Fixed

6.50–6.75%

Locked for 30 years — never changes

Your monthly payment stays the same from day 1 to year 30. No surprises, no rate shock. In volatile markets, this predictability is worth the premium.

Predictable No rate risk Higher rate 10+ yr hold

5/1 ARM

5.25–5.50%

Fixed 5 years, then adjusts annually

Save $392/mo vs. fixed during the initial period. But after year 5, your rate adjusts with the market. Best if you plan to sell or refinance before the adjustment kicks in.

Lower initial $23K saved / 5yr Rate uncertainty 5–7 yr hold

ARM Mechanics

How ARMs Actually Work

An ARM has moving parts. Understanding the timeline, caps, and adjustment formula is essential before choosing one.

🕑

5/1

Initial Period

Rate locked for 5 years. Your payment stays fixed during this window. Common terms: 3/1, 5/1, 7/1, 10/1.

📈

SOFR

Index Rate

Secured Overnight Financing Rate. The market benchmark your ARM tracks after the fixed period ends.

2.75%

Margin

Set by your lender, stays constant forever. Your adjusted rate = Index + Margin.

🛡

2/2/6

Rate Caps

Protects you. 2% first adjustment cap, 2% periodic cap, 6% lifetime cap above your initial rate.

Here's what actually happens to a 5/1 ARM at 5.25% on a $500K loan over time:

Years 1–5

5.25%

Fixed period. Rate locked. Predictable payments. You're saving vs. fixed-rate borrowers.

$2,761/mo

Year 6 — First Adjustment

6.25%

SOFR at 3.50% + 2.75% margin = 6.25%. Within the 2% initial cap. Rate rises.

$3,084/mo

Year 7+ — Worst Case

7.25%

If SOFR spikes to 4.50%: 4.50% + 2.75% = 7.25%. Capped by periodic 2% cap.

$3,413/mo

💡

The ARM Exit Strategy

ARMs are powerful tools if you have a plan. The typical ARM borrower saves $23K+ in years 1–5, then either sells, refinances into a fixed rate when conditions improve, or rides a favorable adjustment. The mistake is entering an ARM without knowing your exit.

Refinance Analysis

Should You Refinance Now?

The math is simple: do your interest savings exceed the closing costs? Here are two real scenarios.

✓ Refinance — Yes

Locked at 7.0% Last Year

You locked at 7% in 2025. Today's 6.50% saves you $150/mo on a $500K loan. With $10K in closing costs, you break even in 67 months.

Current Rate7.00%

New Rate6.50%

Monthly Savings$150

Break-Even67 months

10-Yr Net Savings$8,000

✗ Refinance — No

Locked at 3.5% in 2021

You have a pandemic-era rate. Refinancing to 6.50% would cost you $1,000+/mo more. Keep your existing mortgage — it's a generational asset.

Current Rate3.50%

Today's Rate6.50%

Monthly Increase+$1,050

Break-EvenNever

VerdictKeep 3.5%

Break-Even Formula

Break-Even Months = Closing Costs ÷ Monthly Savings

Example: $10,000 ÷ $150/mo = 67 months (5.5 years). If staying longer, refinance is worth it.

Rate Outlook

Where Mortgage Rates Are Heading

Mortgage rates track the 10-Year Treasury yield — not the Fed Funds Rate directly. Geopolitical conditions drive the spread.

▲ Bull Case

De-Escalation

5.50–6.00%

Geopolitical tensions ease. Treasury yields normalize to 3.8–4.0%. Refinance window opens. Millions of homeowners benefit.

▬ Base Case

Status Quo

6.25–6.75%

Uncertainty persists. Yields sticky at 4.30–4.50%. Rates stay elevated. Most likely near-term scenario. Market in holding pattern.

▼ Bear Case

Escalation

7.00%+

Conflict widens. Risk premiums spike. Treasury yields surge past 5.0%. Affordability crisis deepens. Homebuying freezes.

Watch the 10-Year Treasury, Not the Fed

The Fed Funds Rate (3.50%) is the overnight bank lending rate. Mortgage rates track the 10-Year Treasury (4.44%). The gap between them explains why mortgage rates haven't fallen despite the Fed holding steady. A ceasefire announcement could trigger a 0.50–1.00% mortgage rate drop within days.
