HECM line of credit or cash reserve: which is the better buffer for a down market?

What problem are we solving?

Sequence-of-returns risk. A bad market in the first years of retirement, while the client is withdrawing, can do lasting damage to the portfolio. The fix is a source of spending money that doesn't depend on the market, so the client doesn't sell low.

How do the two buffers compare?

	Cash reserve	HECM line of credit
Upfront cost	None	Closing costs and a 2% FHA insurance premium (often paid from the loan)
While unused	Earns cash-like returns; money isn't invested	Unused credit grows at the loan's rate plus 0.5% a year; nothing owed
When used	Reduces savings	Balance grows with interest; no monthly payment required
Refilling it	Sell investments later	Pay it back any time, and the credit becomes available again
Size	Limited by what the client sets aside	Based on age, home value, and rates
Requirements	None	Age 62+, primary residence, taxes, insurance, and upkeep

When does the line of credit make the most sense?

• The client has substantial home equity and plans to stay in the home
• Holding a large cash reserve would drag on long-term growth
• The client is early in retirement, when the line has years to grow
• The client is comfortable with a loan against the home as part of the plan

Can they be used together?

Yes. A common approach is a modest cash reserve for everyday surprises and a HECM line for a bigger or longer downturn. After a recovery, the client can repay the line from gains, and the credit becomes available again. See how the line of credit grows.

Our take

I don't set the investment strategy; you do. What I can do is give you written numbers for the line today and how it could grow, so you can test it in your own planning software against a cash bucket or a bond ladder. The math should decide, not the reputation.
