I’m Duane Buziak Mortgage Maestro, and here is an illustrative example (illustrative only, not a quote): you buy a $1,200,000 home with a $960,000 loan, your monthly housing payment of principal, interest, taxes and insurance is $7,400, and the file calls for 12 months of reserves. That is $7,400 × 12 = $88,800 that must still be in verified accounts after your down payment and closing costs are paid.

Mortgage loan reserves are liquid or near-liquid assets left over after the down payment and closing costs, measured in months of your housing payment. The number you need depends on the loan program, how you will occupy the property, the loan size and the specifics of your file. I’m a broker, so I shop your loan across multiple wholesale lenders and compare how each treats your assets. This article covers how reserves are measured, what counts, how requirements differ by loan type, what they look like in dollars, how complex files are handled, and how to document everything before you make an offer.

How Are Mortgage Loan Reserves Measured and Why Do Underwriters Require Them?

Reserves are the verified assets you still hold after closing, expressed as a number of months of PITIA. PITIA stands for principal, interest, taxes, insurance and association dues. If a property has no association, it is simply PITI, but the same logic applies.

You can replicate the opener’s arithmetic yourself. Take the full monthly housing payment, multiply it by the required number of months, then confirm your eligible assets exceed that figure after subtracting the cash you need to close. In the example, $7,400 × 12 = $88,800. If you hold $400,000 in eligible accounts and need $290,000 for the down payment, closing costs and prepaid items, you are left with $110,000, which covers the $88,800 with room to spare.

Underwriters require reserves because they show you can keep paying through an interruption in income. A larger loan means a larger payment and a longer fall if something goes wrong, so reserves offset risk on jumbo loans. The same reasoning applies to second homes and investment properties, where the borrower is carrying an additional obligation beyond a primary residence.

What reserves are not

• Not the down payment. Funds used to buy the home cannot also be counted as what remains after closing.
• Not closing costs. Those are paid at the table and subtracted first.
• Not earnest money already spent. A deposit that has left your account is part of your cash to close.
• Not a fee. Nobody is paid reserves. The money stays in your accounts, in your name.

What Assets Count Toward Reserves, and What Gets Discounted?

Assets generally accepted for reserves include checking and savings accounts, money market accounts, brokerage accounts and vested retirement funds. The nuance is in how they are valued. Cash counts at face value. Assets that can swing in price or carry taxes and penalties on withdrawal are often counted at a reduced value, and investors differ on how much of a reduction applies. I won’t quote a percentage here because it varies by investor and program, and I confirm it for your file before you rely on it.

Several items are commonly excluded or restricted, and treatment varies by investor:

• Gift funds. Many programs allow gifts toward the down payment but limit or prohibit them as reserves.
• Unvested stock or options. If you cannot access it today, it usually does not count as a liquid asset.
• Business accounts. Money your company needs to operate may be excluded, and using it can require a review of the business’s cash flow.
• Borrowed funds. Cash drawn against the same asset you are trying to count, such as a loan secured by a brokerage account, can be treated as debt rather than an asset.

An illustrative comparison

Suppose you hold $200,000 and the file requires $88,800 in reserves (illustrative only, not a quote). If all $200,000 sits in savings, it counts at $200,000 and your reserves are met with $111,200 to spare. If the same $200,000 sits in a brokerage account, the investor may count it at a reduced value, and the cushion shrinks by an amount that depends on their rule. If it sits in a retirement account, the investor may apply a different treatment again, and if it is a gift, it may not count toward reserves at all. The dollars are identical. How they are held decides how they are counted, which is why I ask where every dollar sits before you choose a program.

How Many Months of Reserves Do Different Loan Types Require?

Conforming, high-balance, jumbo, second-home, investment, DSCR (debt service coverage ratio) and asset-depletion loans each treat reserves differently. For conforming loans, the official sources are the Fannie Mae Selling Guide, which addresses minimum reserve requirements in its underwriting section, and the Freddie Mac Single-Family Seller/Servicer Guide. These rules are updated periodically, so I do not state a month count from memory. As of November 2026, you should read the current text at those pages, or have me walk you through it against your file.

Jumbo and non-QM (non-qualified mortgage) requirements are set by each investor, not by a single public rulebook. Two wholesale lenders can look at the same borrower and ask for different reserves. That is a concept worth understanding before you assume one number applies to you. For a fuller picture of how jumbo loans work, see my jumbo guide. [LINK: jumbo pillar]

Several factors can move the requirement up or down: the loan amount, your credit profile, how you will occupy the home, how many financed properties you own, and the findings returned by the automated underwriting system. Approval and requirements depend on the file.

What Does a Reserve Requirement Look Like in Total Monthly Cost?

The requirement is a multiple of your monthly housing cost, so the first step is building that cost. The table below uses the $960,000 loan from the opener, 20 percent down ($240,000 on $1,200,000), and an assumed 30-year fixed cost of 6.50 percent, illustrative only, not a quote. At that assumption, principal and interest is about $6,068 a month. I assumed property tax at 1.0 percent of the purchase price and a homeowners insurance estimate. Your county’s actual tax rate comes from your county assessor’s current published rate, which varies widely, so replace my assumption with it before relying on the total.

Once you have the monthly cost, reserves are plain multiplication. This is arithmetic, not a requirement:

• 6 months: $7,400 × 6 = $44,400
• 12 months: $7,400 × 12 = $88,800
• 18 months: $7,400 × 18 = $133,200

Notice that a higher payment raises every one of those figures. A buyer who adds a $900 monthly association fee into PITIA also adds $10,800 to a 12-month requirement.

Loan size also determines which category you fall into, so here is one current, verified data point:

Higher-cost counties have higher limits, so the $960,000 loan could be high-balance conforming or jumbo depending on where the property sits. Confirm your county’s limit at fhfa.gov.

How Do Borrowers with Complex Income or Assets Handle Reserves?

Self-employed and physician borrowers

If you are self-employed, reserves interact with how your income is documented. A bank-statement program, a tax-return program and a contract-based program for a physician with a signed employment agreement may each ask for different reserves. The file determines the path, not a blanket rule. A physician starting a new contract may have thin liquid assets but a strong signed agreement, and some investors weigh that differently than others.

Asset-depletion borrowers

With an asset-depletion program, an investor converts your assets into a qualifying income figure. The question is whether the same dollars can then also count as reserves. Investors differ on whether that double counting is allowed, and some require reserves to come from assets beyond those used for income. Confirm the program’s treatment before you build your plan around it.

Second-home and investor scenarios

Owning multiple financed properties can raise reserve expectations, because each additional mortgage is another payment you must be able to carry. Rental income may offset some of that on an investment property, but how it is credited is investor-specific. I keep this conceptual because the specifics change by program, and approval depends on the file.

What Is the Step Path to Documenting Reserves Before You Make an Offer?

1. List every account and its owner. Note the institution, account type and whose name is on it.
2. Gather the most recent statements. Two months of statements is common, but verify the requirement for the specific program.
3. Document large deposits. Any unusual deposit needs a paper trail showing where it came from.
4. Sequence asset moves before you apply. If you plan to sell securities or transfer funds, do it early so the money has time to season, meaning it has sat in the account long enough to be treated as yours.
5. Do not retitle or move funds without talking to me first. A well-meant transfer can create a sourcing question that delays your file.

The timeline depends on how quickly statements arrive, the type of account, how many large deposits need explaining, and whether assets must be liquidated or seasoned.

The last step is a soft pull pre-approval through the NoTouch Credit Pull, which does not affect your credit score, subject to credit approval and underwriting guidelines. Call 804-212-8663 or start at the pre-approval page. [LINK: pre-approval page] I am licensed in VA, FL, TN, GA, DC, NC, SC, MD, TX, KY and WV, and I shop your loan across multiple wholesale lenders, so I can match your assets to the investor whose treatment fits.

This process fits you if your liquidity is clearly documented and in accessible accounts. It fits less well if your liquidity is thin or concentrated in restricted assets such as unvested stock, business operating accounts or gift funds. In that case, tell me early, because the right answer may be a different program, a different timeline or a conversation about what to build before you offer.

Broker vs. Bank: Who Handles Reserve Requirements Differently?

A single-lender shelf offers that lender’s products and applies that lender’s overlays, which are extra rules on top of agency or investor guidelines. An independent broker can compare options across multiple wholesale lenders. One wholesale lender’s overlay on reserves may differ from another’s, so I can place a file with the investor whose treatment of your assets fits.

These are structural descriptions only. Verify each company’s current model on its own site, since structures can change.

The Takeaway: Certainty at Closing, and the One Thing to Do Next
