What reserves are
Reserves are liquid or near-liquid assets left after closing, measured in months of the new housing payment. Jumbo lenders typically require more reserves than conforming loans.
Why they matter
Larger loans carry more risk for lenders who often hold them or sell them to private investors. Reserves show you can keep paying through a disruption.
Why jumbo lenders look closely at reserves and how assets are documented.
What counts
Checking, savings, money market accounts, stocks, bonds and mutual funds usually count. Retirement accounts may count at a reduced value to reflect taxes and penalties if withdrawn.
Cash-out proceeds
Some lenders allow cash-out proceeds to count toward reserves; others do not. Ask before you plan.
Documentation
Expect two months of complete statements for each account, with explanations for large deposits.
Multiple properties
If you own other financed properties, lenders may require additional reserves for each.
Business assets
Business funds may count only with proof that using them will not harm the business.
Gift funds
Gifts are treated under each lender's rules and may be limited on refinances.
Planning
Avoid moving money between accounts during the process, since each transfer must be traced.
Compare lenders
Jumbo guidelines vary widely, so comparing lenders can matter more than in conforming lending.
