How to Use

Designed for high-value properties: adjust the proprietary boost and accrual rate to compare rough proceeds and growth.

Formula

Principal limit ≈ min(cap, HUD-like age curve × jumbo multiplier) × value; balance grows at your entered accrual rate.

Proprietary reverse mortgage guide (jumbo, no-FHA-MIP model)

Use this calculator to evaluate private-lender reverse mortgage scenarios for high-value homes, compare against HECM constraints, and estimate long-term equity outcomes.

Why proprietary reverse mortgages are different

Proprietary reverse products are private-lender programs, not FHA-insured HECMs. That usually means higher property-value coverage, broader property-type acceptance in some programs, different age thresholds by lender/state, and no FHA mortgage-insurance premium structure.

Inputs unique to jumbo/proprietary analysis

  • Property type: includes formats that may differ from FHA approval rules.
  • Credit score range: some private programs require minimum thresholds.
  • Loan program selector: lender families have different payout curves.
  • Rate structure and rate level: strongly affects long-run balance growth.

Why the HECM comparison chart matters

On high-value homes, the claim-limit cap can create large cash-availability differences. Side-by-side bars for available cash and upfront costs help users understand when proprietary products deliver more net proceeds, and where higher rates may offset that advantage over time.

Three charts you should read together

  • Loan balance vs home value: core risk path over time.
  • HECM vs proprietary bars: immediate cash and cost trade-off snapshot.
  • Equity remaining area: inheritance-focused long-horizon view.

Practical decision flow

  • Check eligibility flags first (age, credit, property type).
  • Compare HECM and proprietary available cash side-by-side.
  • Stress test rates and appreciation assumptions for conservative outcomes.
  • Review equity chart with heirs if estate planning is a priority.

FAQ

How is this different from FHA HECM?
Proprietary products are private; terms, PLFs, and costs differ widely by lender.
Are jumbo factors stable?
No—treat multiplier as a sensitivity knob, not a guarantee.
What about non-borrowing spouses?
Eligibility rules are complex—this tool does not model spouse protections.
