Advisor Tool

Lump-Sum Strategy ComparatorIllustration only

Compare three uses of a client's available cash against a rental mortgage: pay it down, invest it, or hold it in a first-lien sweep HELOC that offsets interest while staying liquid. Designed for RIAs, CPAs, and wealth advisors.

This tool is for illustration only and does not provide investment, tax, or legal advice. Consult your own financial, tax, and legal advisors before making decisions.

Enter an investment return assumption above to see the full comparison. Paying down the mortgage is a fixed return at the mortgage rate but locks cash in property equity. The sweep HELOC keeps cash liquid and offsets HELOC interest, but is adjustable-rate.

The sweep option compares the gross interest offset from the cash balance. It does not factor in any rate differential between your current mortgage and the HELOC. The sweep HELOC investment-property line is capped at $1MM and has eligibility limits; not suitable for everyone.
