What Are Cash Reserves and Why Might a Lender Require Them?
Qualifying for a mortgage payment on paper and being able to actually make that payment if a paycheck is delayed or an emergency comes up are two different things, and reserves are one way lenders address that gap.
The short answer
Cash reserves are funds a borrower needs to have available after closing, separate from the down payment and closing costs, usually measured as a set number of months’ worth of the mortgage payment. Not every loan requires reserves, but they show up commonly on certain loan programs, investment properties, and files that carry other risk factors, functioning as a cushion in case income is disrupted shortly after moving in.
How reserves are typically measured
Reserve requirements are usually expressed as a number of months of PITI, principal, interest, taxes, and insurance, rather than a flat dollar figure, since that keeps the requirement proportional to the size of the loan itself. The exact number depends heavily on the loan program, the property type, and the rest of the borrower’s file. Two borrowers buying similarly priced homes can end up with very different reserve requirements if one is financing a primary residence with strong credit and the other is financing a second home with a thinner credit file.
When reserves are commonly required
Reserves tend to show up more often on loans for investment or second homes, since a property that isn’t the borrower’s primary residence is generally viewed as carrying more risk of being let go if money gets tight. They can also appear when a borrower has a lower credit score, a higher debt-to-income ratio, or self-employment income that’s harder to predict, since reserves offset some of that added uncertainty from a lender’s perspective. Some loan programs waive reserve requirements entirely for well-qualified borrowers on primary residences. A borrower already carrying multiple financed properties may also see reserve requirements stack, since a lender can ask for a cushion tied to each property rather than just the one being purchased.
How reserve funds need to be documented
Like other mortgage funds, reserves generally need to be sourced and seasoned, meaning a lender wants to see where the money came from and confirm it’s been sitting in the account long enough to count, following much the same logic covered under sourcing and seasoning funds. This typically comes from the same bank statements used to verify the down payment, so reserves aren’t usually a separate document hunt, just a separate line item within the same paperwork.
What to weigh
Reserves are separate from, and sit on top of, whatever a borrower otherwise thinks of as an emergency fund, since a lender is specifically checking for funds set aside for the mortgage payment rather than everyday financial cushioning. A borrower who has been treating a savings balance as flexible, general-purpose money may need to rethink that plan once a lender earmarks part of it as a reserve requirement that has to remain in place through closing. Because reserve requirements vary widely by lender, loan program, and individual file, and can change over time, it’s worth confirming the specific requirement for a given loan rather than assuming a general rule applies.
