Reserves are money you still have after closing, measured in months of your full mortgage payment. Many loans for a primary home require none or a couple of months, while second homes, investment properties, jumbo loans and borrowers with high debt ratios often need six months or more. Separately from what a lender requires, most buyers should keep at least three to six months of expenses for repairs and emergencies.
What counts as reserves
Lenders measure reserves in months of PITIA: principal, interest, taxes, insurance and HOA dues. If your payment is $2,800, two months of reserves is $5,600.
- Counts: checking and savings, money market accounts, stocks and bonds, and often a share (commonly 60% to 70%) of vested retirement balances.
- Usually doesn’t count: money you’ll use for the down payment and closing costs, cash you can’t document, and most gift money for reserves.
When lenders require more
| Situation | Typical requirement |
|---|---|
| Primary home, strong file | Often none to 2 months |
| High debt-to-income ratio or lower credit score | Often 2 to 6 months |
| 2 to 4 unit home | Often 6 months |
| Second home or investment property | Often 2 to 6+ months, more if you own several |
| Jumbo loan | Often 6 to 12+ months |
Exact requirements depend on the loan program and your overall file. Strong reserves can also offset other weaknesses, like a higher debt ratio.
Try it: True cost to buySee the cash to buy and the first-year costs of owning together, so you know what’s left after closing.How much you should keep
New homeowners almost always face unexpected costs in the first year: a failed water heater, a repair the inspection missed, furniture, window coverings, tools. A cushion of three to six months of total living expenses, kept separate from your home repair fund, is a sensible target.
Balancing reserves with your down payment
It can be tempting to put every dollar into the down payment to reach 20% and avoid mortgage insurance. Often it’s better to put down a little less and keep reserves. Compare the cost with the PMI calculator: mortgage insurance can usually be removed later, but a repair you can’t pay for goes on a credit card.
Document your reserves
Lenders verify reserves with your most recent statements, usually two months. Keep accounts stable and avoid large unexplained transfers; see the pre-approval document checklist. Plan the whole budget, including reserves, with the cash to close calculator.
