What are jumbo loan reserves?

Reserves are liquid assets you must have available AFTER closing — enough to cover several months of total mortgage payments (PITI: principal + interest + taxes + insurance + HOA) if your income is disrupted. For jumbo loans, reserve requirements are far more stringent than conforming loans because the lender retains the loan in portfolio (no Fannie/Freddie buyer) and bears the full default risk.

Reserves prove you can continue making payments through a layoff, business downturn, or medical event without the lender immediately facing default. The bigger the loan, the more months required — and the asset types accepted are limited and discounted.

Acceptable assets and discount factors

Not all assets count at 100% face value. Lenders apply discounts to account for liquidation costs, taxes, and market volatility:

Asset depletion as an income alternative

If your income doesn't qualify but you have substantial assets, some jumbo lenders allow asset depletion qualification: divide your discounted eligible assets by 240 months (for 30-year loan) to generate "income" for DTI calculation. Example: $2M in brokerage assets ÷ 240 = $8,333/month phantom income. Combined with W-2 income, this can qualify you for loans well above traditional DTI limits. Asset depletion is most common with retirees, high-net-worth entrepreneurs, and trust beneficiaries.
