Jumbo Reserves & Assets
Jumbo underwriting often puts more emphasis on post-closing liquidity.
Reserves
Required months of reserves can change with loan amount, number of financed properties, occupancy, LTV and investor. Never publish one reserve number as the jumbo standard.
Eligible assets
Cash, retirement, securities, vested assets, business funds and other sources can receive different treatment by investor, including different haircut or liquidity rules.
Jumbo is investor-specific. Unlike Fannie Mae, Freddie Mac, FHA, VA or USDA, there is no single national jumbo underwriting handbook. Credit score, LTV, DTI, reserves, loan size, property, appraisal and income rules can vary materially by investor and lender. This page explains common underwriting concepts—not a universal approval matrix.
