Reserves are where clean files get stopped. You can have the down payment, the credit, and the ratio — and still fall short on the money you're required to hold afterward.

Most investors budget carefully for the down payment and closing costs. Far fewer budget for reserves — the cash a lender requires you to still hold after the deal closes.
It produces a specific and frustrating scenario: a borrower with 25% down, a strong credit score, and a coverage ratio well above the floor gets to underwriting, is asked for six months of reserves, and discovers they have a few thousand dollars left after closing. The file was never weak. The cash planning was.
Reserves exist because the lender is asking a reasonable question: if this property sits vacant for two months, or the water heater fails, can you make the payment without missing one? That question has nothing to do with your down payment.
We tell you the reserve requirement early, so you can plan cash rather than discover a gap during underwriting.
Reserves held in your entity's account generally qualify, which matters since most investors close in an LLC.
Stronger coverage ratios and lower leverage typically mean lighter reserve requirements. Improving the deal improves this too.

If you hold several properties, reserve requirements may be assessed across the portfolio rather than in isolation.
Reserve surprises stall closings. Knowing the figure at the start keeps your timeline intact.
Reserves are expressed in months of PITIA — principal, interest, taxes, insurance, and any association dues. Not months of your mortgage payment alone; the full carrying cost.
The arithmetic is straightforward but the number is often larger than investors expect. On a property with $2,300 in monthly PITIA, a six-month reserve requirement means roughly $13,800 held after closing. A twelve-month requirement means roughly $27,600. That is on top of your down payment and closing costs, not included in them.
Requirements across the market in 2026 commonly fall between three and twelve months depending on the lender and the file, with six months a frequent middle point. Larger loans often carry higher requirements.
Reserve requirements are not fixed — they respond to how the lender reads the risk in your file:
This is where files most often hit a snag. A few practical points:
Funds must be verifiable and liquid. Bank statements, brokerage accounts, and similar accessible holdings generally work. Equity in another property does not.
Statements must be current. Lenders typically want statements dated within a recent window, often 60 days. If your closing timeline stretches, expect a request for updated statements — plan for it rather than being caught by it.
Seasoning may apply. Some lenders want reserve funds to have been in the account for a period before closing, commonly 30 to 60 days, to confirm they are not borrowed for the occasion.
Entity accounts generally qualify. Funds held in your LLC's account usually count, provided the account matches the entity documents on file.
Do not count money twice. The single most common planning error. If a sum is earmarked for reserves, it cannot also cover an appraisal gap, a repair, or your next down payment. Reserve capital is committed capital.
Three practical steps prevent most reserve problems:
Ask the number first. Before you go under contract, ask any lender what reserves they will require on your specific scenario. It is a simple question with a specific answer.
Calculate against real PITIA. Use the lender's actual payment figure including taxes and insurance, not an estimate. In markets with high insurance costs, that difference is significant — use our DSCR calculator to get an accurate PITIA before you budget.
Improve the deal to lighten the requirement. A larger down payment lowers the payment, which lowers PITIA, which lowers the total reserve figure — and it improves your ratio at the same time. It works on several fronts at once.
