The Quick Read: Reserves on a conventional cash-out depend on four things: how you use the home, how many units it has, your debt-to-income ratio, and how many other properties you finance. A one-unit home you live in carries no base reserve minimum. A two- to four-unit home does. Once your ratio climbs past 45% on an automated file, even the one-unit owner needs six months.
Key Takeaways
- Reserves are the money you still hold after closing, counted in months of the home’s full payment.
- One-unit primary residence: no base minimum, but a ratio above 45% triggers six months on an automated cash-out.
- Two- to four-unit primary residence: minimum reserves apply, and the leverage cap drops to 75%.
- Cash-out proceeds from the same home do not count toward your reserves.
- The automated underwriting finding can ask for more than the written minimum.
What Are Reserves, and Why Does a Cash-Out Care?
Reserves are your liquid assets left over after the loan closes. Lenders count them in months of the property’s housing payment: principal, interest, taxes, insurance and any association dues. Brokers call that payment PITIA, and you will see the term on your paperwork.
Why does a cash-out care? You are pulling equity out and usually raising the balance. The lender wants proof you could keep paying if income dipped for a few months. A refinance that simply lowers the balance carries less of that risk. A cash-out carries more.
Across the wholesale programs Lendmire places files with, reserves rarely sink a borrower who plans ahead. They sink the borrower who finds out at the last step that the money was in the wrong place.
The Master Grid: Occupancy by Unit Count
Occupancy and unit count set both your leverage cap and your reserve treatment. Here is the grid for a conventional cash-out, subject to lender guidelines and full file review.
| Property | Max cash-out LTV | Reserve treatment |
|---|---|---|
| 1-unit primary residence | 80% | None at base; 6 months if DTI above 45% |
| 2–4-unit primary residence | 75% | Minimum reserves apply |
| 1-unit second home | 75% | Reserves apply; more if DTI above 45% |
| Investment property | 75% | Reserves apply, with extra for multiple loans |
LTV means loan-to-value: the new loan balance divided by the appraised value. DTI is your total monthly debts divided by your gross monthly income.
Second-home cash-outs exist only for one unit. There is no multi-unit second-home row. If you are weighing a rental, occupancy decides the leverage, and the rest of this article stays focused on the home you live in.
The exact month counts for second homes and investment properties depend on the automated findings and the current agency guide. Your loan officer should confirm them against the live guide before you plan around any number.
One-Unit Primary Residence: Where the DTI Switch Lives
The one-unit home you live in is the easiest lane. Fannie Mae’s reserve rules say there is no minimum reserve requirement for one-unit principal residence transactions. That is where the myth “owner-occupied never needs reserves” comes from. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Here is the catch. Fannie Mae’s cash-out rules add that when an automated casefile shows a DTI above 45%, six months of reserves are required. The Eligibility Matrix repeats the same trigger.
Picture a homeowner with a one-unit house, a solid score and a 46% ratio after the new loan. No base minimum applies. The ratio trips the six-month requirement anyway. In plain terms, six months means six times the full monthly housing payment, held in eligible accounts after closing.
Now picture the same homeowner at 41%. Under the written rule, no minimum applies. The automated system can still ask for more based on its overall risk read, so “none required” is the floor, not a promise.
This is why the reserve question and the ratio question are really one question. If you want the credit and ratio side in one place, Lendmire’s piece Conventional Cash-Out Refinance Credit Requirements by Occupancy and LTV covers it.
Two- to Four-Unit Primary Residence: Live In One, Rent the Rest
Living in one unit of a duplex, triplex or fourplex puts you in a different lane than a one-unit owner. Minimum reserves apply on a two- to four-unit principal residence, and the cash-out leverage cap is 75% instead of 80%. Both come straight from the agency documents above.
This surprises people. You live there, so it feels like a primary residence. The agencies see more moving parts: more units, more tenants and more ways for income to wobble. Owner occupancy lowers the risk. It does not erase it.
The month count for this tier is set by the automated findings or, on a manual file, by the Eligibility Matrix. On the files we see, six months is a common figure. Treat that as a planning number and let your loan officer confirm it.
Rental income from the other units can help your income side on a two- to four-unit loan. Freddie Mac says so on its multi-unit page, though it also caps manually underwritten loans at a 45% ratio. Better income can pull your ratio down, which matters for the next section.
How Do the Requirements Stack?
Do the DTI trigger and the unit-count minimum add together? The written rules do not say they do. The practical read is that the automated system returns one reserve requirement for your file. The larger driver governs, and the system can still ask for more. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Think of the stacking in order:
1. Base requirement by occupancy and unit count. None for a one-unit primary. Minimum reserves for two to four units, second homes and investment properties.
2. The ratio switch. DTI above 45% on an automated cash-out moves you to six months.
3. The automated finding. It can require extra reserves on top of the written floor, based on the whole file.
4. Other financed properties. Extra reserves tie to second homes and investment properties. The subject property and your principal residence are left out of those added calculations. For an owner-occupant refinancing the home they live in, this step mostly does not apply.
A two- to four-unit owner with a ratio below 45% sits at the unit-count minimum. The same owner above 45% should not assume the two numbers pile up. Ask for the final figure from the automated finding, and plan with some cushion.
What Counts as Reserves, and What Does Not
Reserves must come from eligible, documented sources. Freddie Mac’s reserve section defines them as assets left after closing and points to its own documentation rules for what qualifies. Typical eligible sources include checking, savings and other liquid accounts with a paper trail.
The big exclusion is the one that trips people up. Cash you receive from this same cash-out is not reserve money on the files we place. A borrower who plans to “fund the reserves from the proceeds” will find the plan fails. Your reserves have to exist before the cash-out lands.
Fannie Mae also asks for reserves equal to the balance of 30-day accounts, such as a charge card that must be paid in full each month. On a refinance, that balance is reduced by the cash back you receive. Mention these accounts to your loan officer up front.
Three other file problems come up often:
- Large, unexplained deposits. Lenders want to see where the money came from.
- Money in the wrong place. Funds you must use to pay off debts at closing are no longer reserves.
- Thin paper trails. Cash stashed outside an account is invisible to underwriting.
Manual Underwriting vs. Automated Underwriting
Most files run through automated underwriting, which returns a finding. Some files, usually those with credit events or odd income, go to a human underwriter instead. The rules shift on a manual file.
On a manual file, Fannie Mae sends the reserve question to the Eligibility Matrix, and manual ratio ceilings are tighter than the automated 50% ceiling. Freddie Mac requires verification of funds and reserves on every manually underwritten refinance.
Freddie Mac’s reserve number also depends on how the loan is underwritten, so there is no single fixed table to quote. Describe it this way: the system or manual rules set the number, and your loan officer confirms it. The two agencies are built differently, so do not assume identical results.
Where the General Rule Breaks
A few edge cases move the number or the eligibility itself.
Limited cash-out is a different loan. A rate-and-term refinance pays off your first mortgage, closing costs and any purchase-money second lien, with only incidental cash back. It runs up to 95% on a one-unit primary residence. Reserve treatment tracks the transaction type, so the same house can have different reserve results under each.
High-LTV refinance loans are exempt. Fannie Mae exempts them from minimum reserves, but acquisition of that product is suspended. Do not count on it.
Delayed financing. If you paid cash for the home, a delayed-financing exception can let you take cash out without the usual waiting period. The purchase must have been arm’s length and the source of your cash documented.
Seasoning. Cash-out needs the first mortgage you are paying off to be at least 12 months old, measured note date to note date. At least one borrower must also have been on title for six months. Exceptions cover inheritance, legal awards, and subordinate liens being paid off. A wholesale lane that reaches 89.99% LTV with no mortgage insurance carries its own six-month seasoning. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Texas homestead. A cash-out on a Texas homestead is capped by the state constitution at the agency figure, and the higher wholesale lane is not written there.
HELOC payoffs. Paying off a home equity line you used for something other than buying the home can make the transaction a cash-out. Confirm the classification before you assume a rate-and-term.
Run a Self-Check Before You Apply
You can estimate your reserve position in five steps.
1. Pick your row. Occupancy and unit count set your base.
2. Estimate your ratio. Add your new housing payment to your other monthly debts, then divide by gross monthly income. If you land above 45%, plan on six months.
3. Count the months. Take your eligible liquid assets and divide by the full housing payment. That is your months of reserves.
4. Subtract what leaves. Remove money needed for closing costs or paying off debts at closing. Remove anything you cannot document.
5. Leave a cushion. The automated finding can ask for more than the written minimum.
A homeowner holding eight months in documented savings against a six-month trigger has a cushion. One holding exactly six has none, and a single closing-cost surprise can flip the result.
Closing costs deserve their own thought. CFPB research finds cash-out borrowers commonly use proceeds to cover them. That research also warns that converting non-mortgage debt into mortgage debt puts the home at risk if payments become unsustainable. Costs rolled into the loan add to the balance and to what you pay in interest. Run your reserves after you account for them.
Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
Mistakes That Sink the File
- Assuming a primary residence never needs reserves. The ratio trigger says otherwise.
- Treating a duplex like a single-family home. Two to four units move you to a 75% cap and a reserve minimum.
- Counting the cash-out as your cushion. It does not count.
- Draining savings for closing costs first. Reserves are measured after closing.
- Ignoring a ratio just over 45%. It is the hidden switch.
- Using a number from a random website. Quoted figures differ because sources blur agency rules with lender overlays and use old data. Ask for the current figure in writing.
Key Terms Defined
Reserves: liquid assets you still hold after closing, counted in months of your housing payment.
PITIA: principal, interest, taxes, insurance and association dues; the full monthly housing payment reserves are measured against.
DTI (debt-to-income ratio): your total monthly debts divided by your gross monthly income.
LTV (loan-to-value): your new loan balance divided by the home’s appraised value.
Cash-out refinance: a new first mortgage that pays off the old loan and gives you cash from your equity.
Limited cash-out (rate-and-term) refinance: a refinance that pays off the old loan and closing costs with only incidental cash back.
Seasoning: the required waiting period on the existing loan or on your time on title before a cash-out.
Automated underwriting: the system that reads your file and returns a finding, including any reserve requirement. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
What the Decision Looks Like in Practice
Start with your row on the grid, then your ratio, then your documented savings. If the numbers clear with a cushion, a cash-out may fit. If reserves are thin, you can change the plan: take less cash, pay down a debt first, add income, or wait and build savings.
Equity access and reserve strength pull in opposite directions. More cash out raises your balance and your payment, and a bigger payment means a bigger reserve target. The CFPB paper also notes that a cash-out draws down wealth you could otherwise use later. A smaller draw can be the stronger play.

Frequently Asked Questions
Do I need reserves for a cash-out refinance on my one-unit home?
Not at the base level. Fannie Mae sets no minimum for a one-unit principal residence. But if your ratio is above 45% on an automated cash-out, six months applies. The automated finding can also ask for more.
Why does a duplex need reserves when a single-family home may not?
The agencies treat two- to four-unit principal residences as higher-risk transactions, even when you live in one unit. That is why minimum reserves apply and the leverage cap sits at 75% rather than 80%.
Can my cash-out proceeds count as reserves?
No. Proceeds from the same cash-out are not reserve money on the files we place. You need eligible, documented assets that remain after closing, separate from the cash you receive.
Do Fannie Mae and Freddie Mac set the same reserve numbers?
Not exactly. Fannie Mae publishes transaction types and a ratio trigger, while Freddie Mac’s number depends on how the loan is underwritten. Your loan officer should confirm the figure for your file.
How old must my current loan be before I can take cash out?
The first mortgage being paid off must be at least 12 months old, note date to note date, and a borrower must have been on title for six months. Exceptions include delayed financing, inheritance and legal awards.
