The Quick Read: There is no single national number. Each wholesale lane sets its own, counted in months of your full housing payment. The count rises as the loan amount rises, and it is measured on what you hold after closing, not before. Cash you pull out of the home often cannot count toward it, so plan to show reserves from your other assets, subject to lender guidelines and full file review.
Key Takeaways
- Reserves are money you still hold after the loan closes and after closing costs and payoffs are paid.
- The requirement is a number of months multiplied by your full new payment: principal, interest, taxes, insurance and association dues.
- A bigger loan means a bigger payment and more months. Both push the dollars up.
- Cash-out proceeds are often not allowed to count as reserves. Ask before you assume.
- Retirement and stock balances may be counted at a reduced value, depending on the lender.
What Are Reserves on a Jumbo Cash-Out?
Reserves are your safety cushion. The lender wants proof that after this loan closes, you can still cover the housing payment for a set number of months if your income hiccups.
That matters more on a cash-out. You are borrowing against your equity, and the new balance is larger than the old one. A larger balance means a larger payment, so the cushion has to be bigger too.
A jumbo loan is one that starts a dollar above your county’s conforming limit. Fannie Mae and Freddie Mac cannot buy it, so the lender or the investor behind it sets its own rules. Reserves are one of those rules. That is why you will not find one official number.
Lendmire is a mortgage broker licensed for consumer lending in 16 states. It arranges jumbo loans through wholesale lenders, and its jumbo cash-out refinance program is built around the same idea described here: reserves measured in months of the full payment, rising with the amount.
The wholesale lanes Lendmire works with share a few traits. The headline lane uses a 660 decision score. Leverage reaches 90% on the top lanes, with several stopping at 89.99% combined loan-to-value. The rest stop at 80%. Loans reach $5,000,000 on the largest lanes. Ratio ceilings run 50% on the fixed lanes, 45% on the adjustable lanes and 43% on the interest-only lanes. Cash-out generally gets lower leverage than a purchase. All of this is subject to lender guidelines and full file review, and none of it is a commitment to lend.
Key Terms Defined
Reserves: Liquid or near-liquid assets you still own after the loan closes.
Funds to close: The cash needed at the table for closing costs, payoffs and any other required amount. These come out of your assets before reserves are counted.
Full housing payment: Principal, interest, property taxes, homeowners insurance and any association dues, often called PITIA. Reserve months are counted against this whole number, not just principal and interest.
Cash-out refinance: A new, larger mortgage that pays off your old one and hands you the difference in cash.
Combined loan-to-value (CLTV): All the loans against the home, divided by its appraised value. A cash-out lane caps this at a lower percentage than a purchase lane does.
Seasoning: How long you have owned the home or held the loan before a lender will let you pull cash out.
So How Many Months Does a Jumbo Cash-Out Need?
It depends on the lane and the loan. In the wholesale programs Lendmire places files with, the requirement is stated in months of your full payment, and the months step up as the loan amount climbs. A mid-size jumbo asks for less cushion than a loan near the top of the range.
Other factors move the number as well:
- Loan amount. The biggest driver. Larger loans fall into higher reserve bands.
- Cash-out leverage. Lower leverage or a stronger credit profile often reduces the ask. Higher leverage tends to raise it.
- Credit and ratios. A score near the floor, or a ratio near the ceiling, leaves the lender less room for error, so reserves matter more.
- Occupancy. This article is about the home you live in. A second home or an investment property gets its own leverage and reserve treatment in each lane, and it is usually tougher.
- Number of financed properties. If you carry mortgages on other properties, lenders commonly ask for more.
You will see ranges quoted online, and they disagree with each other. That is normal. Different lenders publish different numbers, and several are out of date. Treat them as background and ask for the figure on your own loan. Lendmire does not quote a single months figure here because the right answer comes from the specific lane and the full file.
How the Reserve Number Is Built, Step by Step
Here is how the math runs on a typical jumbo cash-out file.
1. Loan size sets the track. If the new loan is above your county’s conforming limit, it is a jumbo and follows the investor’s own guidelines. The limit is set by the FHFA and varies by county. FHFA’s loan limit addendum explains how the baseline is set, and the high-cost ceiling cannot exceed 50% above it. Look up your own county. A loan that is jumbo in one county can be conforming in the next.
2. The new payment is computed. The lender totals principal, interest, taxes, insurance and dues on the new, larger balance. Taking more cash raises this number.
3. The lane picks the months. The reserve band that matches your loan amount supplies the multiplier. Occupancy and other financed properties can add to it.
4. Your assets are documented. Expect recent statements for bank, brokerage and retirement accounts. A large deposit with no obvious source usually needs a paper trail.
5. Funds to close come out first. Closing costs and any required payoffs are subtracted from your verified assets. Only what is left can be reserves.
6. Certain assets are discounted or excluded. Unvested funds and unsecured loans do not count. Some lenders reduce retirement and stock balances further.
7. The appraisal sets the value. Cash-out leverage is capped below purchase leverage. On the largest lanes, the cash you can take out may also be capped. Above a lane’s threshold amount, two appraisals are required.
8. The underwriter weighs everything together. Reserves, credit, ratios, leverage and loan size are judged as a set. A strong showing in one area can sometimes offset a thinner one in another, but not by right.
Here is a practitioner’s observation. On jumbo cash-out files, the common surprise is not the reserve months. It is the way funds to close and reserves stack. Borrowers add up their accounts, see a large total, and forget that closing costs and payoffs come out of it before reserves are counted.
Do Cash-Out Proceeds Count as Reserves?
Often, no. Many programs treat money pulled out of the property as not available for reserves, and that is especially common on second homes and investment properties. Policy differs by lane. Ask the question up front, before you plan your asset documentation.
Think of three separate pools of money:
| Pool | What it is | Counts as reserves? |
|---|---|---|
| Funds to close | Cash for costs and payoffs | No, removed first |
| Reserves | Assets left after closing | Yes, if acceptable |
| Cash-out proceeds | Money paid to you at closing | Often not allowed |
The practical effect is simple. If you plan to use the cash-out to fund your own cushion, you may find the lender will not accept it. You may need to show the reserves from accounts you already hold.
What Counts as a Reserve Asset?
The cleanest public benchmark for defining reserves comes from Fannie Mae. Its Selling Guide section on minimum reserves says reserves are liquid or near-liquid assets available after the mortgage closes. Funds needed to close are subtracted first. That is an agency benchmark, not a jumbo rule. Jumbo lanes borrow the concept and set their own details.
Here is how common assets are usually treated:
| Asset | Typical treatment |
|---|---|
| Checking and savings | Counted, with statements |
| Stocks, bonds, mutual funds | Counted, sometimes discounted |
| CDs and money market funds | Counted, with statements |
| Retirement accounts | Vested amount, often reduced |
| Unvested funds or options | Not counted |
| Personal unsecured loans | Not counted |
Cash value of vested life insurance also appears on the agency’s acceptable list. How much of any of this a given jumbo lender will accept varies, and haircuts on retirement and stock values are a lender choice. Ask which percentage applies to your accounts.
Where the General Rule Breaks
The “reserves equal a set number of months of payment” idea holds up in most files. These cases bend it.
Cash-out versus rate-and-term. A cash-out is treated as the higher-risk transaction. Expect lower leverage and often more reserves than a refinance that only changes the loan terms.
High-balance conforming. In a high-cost county, a loan above the baseline but under the county limit is still conforming. Agency rules apply there, not jumbo rules. Check which side of the line you are on before you compare numbers.
The agency 45% test. Fannie Mae’s Eligibility Matrix ties its cash-out reserve requirement to automated casefiles with a debt-to-income ratio above 45%. Manually underwritten loans use the matrix’s own reserve months. People quote that rule as if it governed jumbos. It does not. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Additional financed properties. The same matrix adds reserves when you carry other financed properties. Jumbo lanes do something similar.
Recent all-cash purchases. The agency’s delayed-financing exception lets someone who bought with cash refinance sooner than the usual six months on title, with documented source of funds. Jumbo lanes set their own seasoning, so ask what your lane requires.
Self-employed borrowers. Some lanes accept alternative documentation. That can come with a heavier reserve ask. Ask early.
Condominiums. Two of the lanes accept non-warrantable condos, which are projects that fall outside standard agency rules. These often carry more conservative terms overall.
A Worked Example, Without the Dollar Signs
Picture a homeowner who wants to take cash out of a primary residence. The home is appraised well above the current balance. The new loan lands in a higher reserve band than the old balance would have.
The lender computes the new full payment. It multiplies that payment by the months the lane requires for that band. That product is the reserve target.
The homeowner then lists accounts. Checking and savings count at face value. A brokerage account counts, possibly at a discount. A retirement account counts at its vested amount, again possibly reduced. The lender subtracts funds to close from that total. What is left must meet or exceed the target.
Now the twist. The homeowner assumed the cash from the refinance would cover the gap. The lender says proceeds cannot be used. The homeowner has three paths: take a smaller cash-out, which lowers the payment and the target; add documented assets; or pick a different lane with a different band.
None of those outcomes is a failure. They are the reason to ask the question first.
Why You See Different Numbers Elsewhere
Three reasons.
First, there is no central authority. FHFA sets loan limits. The CFPB sets the ability-to-repay standard, which requires lenders to make a reasonable, good-faith determination from verified information. Neither one prescribes reserve months. CFPB’s assessment report describes the standard. Reserves are a credit choice by the investor.
Second, programs differ. A lane built for a smaller jumbo asks for less than one built for a very large loan. Quoted ranges often blend several.
Third, pages go stale. A figure from a lender’s glossary may reflect a program that has changed. A conforming rule may be mislabeled as a jumbo rule.
One more point on terminology. A first-lien jumbo can be classed as higher-priced under a pricing test, which is a separate matter from reserves. The CFPB’s explainer on higher-priced mortgages covers it. It is useful context, and it does not change your reserve count.
A Planning Checklist Before You Apply
- Look up your county limit so you know whether you are really in jumbo territory.
- Decide how much cash you actually need. Taking less lowers the payment and the reserve target.
- List every account with a recent statement, and note which are retirement or unvested.
- Estimate funds to close and subtract them from your total before counting reserves.
- Ask whether proceeds can count, and plan as if they cannot.
- Explain large deposits in writing before the underwriter asks.
- Ask about haircuts on retirement and brokerage balances.
- Check seasoning if you bought the home recently.
Frequently Asked Questions
Is there one national reserve requirement for jumbo cash-out loans?
No. Jumbo loans fall outside the Fannie Mae and Freddie Mac rulebooks, so each lender or investor sets its own. Loan amount, leverage, credit and occupancy usually drive the result. The wholesale lanes Lendmire works with count reserves in months of the full payment and step the months up as the amount rises.
Do reserves come on top of closing costs?
Yes, in effect. Funds to close are subtracted from your assets first, and reserves are counted from what remains. So the total you need on hand is the sum of both. Skipping that step is the most common planning error.
Can the cash I take out serve as my reserves?
Often not. Many programs treat cash-out proceeds as unavailable for reserves, especially outside a primary residence. The rule is lender-specific, so ask before you build your plan around it.
Do retirement accounts count in full?
Usually only the vested amount counts, and some lenders count a portion of that. Unvested funds and unsecured loans do not count at all. Ask the lender what percentage applies to your account types.
What happens if I am short on reserves?
You still have options. You can take less cash out, which shrinks the payment and the target. You can document additional assets. Or you can compare a lane with a different reserve structure. Approval remains subject to lender guidelines and full file review.
If you are weighing a cash-out refinance against keeping the loan you have, Lendmire can help you compare the programs and the equity each one reaches.
