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.
2027 jumbo reserve requirement tiers
Typical 2027 reserve requirements by loan size and property type:
- Jumbo $806k-$1M, primary residence, 740+ FICO: 6 months PITI

- FICO under 740: Add 3-6 months
- Down payment under 20%: Add 3-6 months
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:
- Cash, checking, savings, money market: 100%
- CDs (maturing within seasoning period): 100%
- Non-retirement brokerage (stocks, bonds, mutual funds): 70% of market value
- Retirement accounts if under age 59.5: 60% of vested balance (10% penalty + 30% tax discount)
- Retirement accounts if age 59.5+: 70% (no penalty, but tax owed on withdrawal)
- Vested stock options (RSUs): 70%, only if currently vested
- Cash value life insurance: 100% of cash surrender value
- Cryptocurrency: Most jumbo lenders apply 0%-50% discount; some don't accept
- Equity in other real estate: NOT counted as reserves (illiquid)
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.
