We're doing a major rewrite of our 5/1 ARM explainer to help readers understand what they're actually being offered in today's market, calculate the real worst-case scenario, and walk into a lender meeting knowing exactly what to ask. We're looking for loan officers, mortgage brokers, or CFPs actively originating or counseling on ARM products in 2026 — particularly anyone working with new-construction (builder-subsidized) buyers, anyone who advises clients on ARM vs. fixed decisions, or compliance-savvy lenders who can speak to the CHARM booklet and Fannie Mae qualification rules. Questions (pick the 2–3 most relevant to your expertise): 1. A borrower searching "5/1 ARM" today is often being quoted a 5/6 ARM and may not know the difference. What should a buyer ask their loan officer to confirm exactly what ARM product they're being offered, and why does the 5/1 vs. 5/6 distinction matter for how the rate adjusts after year 5? 2. Walk us through a real lifetime-cap scenario on a typical 2026 loan — for example, a $400K balance starting at a 5.5% intro rate with a 2/1/5 cap structure. What does the maximum possible monthly payment look like at the lifetime ceiling, and how should a borrower decide whether they can absorb that payment if everything goes sideways? 3. What are the 5–6 specific questions every ARM borrower should ask their loan officer before signing a loan estimate? We're looking for the index, margin, cap structure, today's fully-indexed rate — and any others you think readers consistently miss. 4. New-construction buyers are being offered builder-subsidized ARM rates in the 3.8%–4.5% range. What's the real catch — is the savings worth it, or is the discount baked into an inflated purchase price? What should buyers do to evaluate these offers properly? 5. For a borrower whose ARM saves them $200–$800 per month vs. the fixed-rate alternative during the fixed period — what's the most financially sound thing to do with that monthly delta? Does it depend on the borrower's risk profile, and how do you actually advise clients on this?
