> How lenders calculate reserves for multiple financed properties, the percentage of unpaid balances rule and which assets satisfy the extra reserve.
Reserves for multiple financed properties add a second layer to the usual reserve requirement. On a Fannie Mae loan, the borrower holds months of payments for the new loan plus a percentage of the unpaid balances on their other financed properties: 2% for one to four, 4% for five to six, 6% for seven to ten.

## How are reserves for multiple financed properties calculated?

Reserves for multiple financed properties are calculated in two parts and then added. The first part is the reserve for the loan being made, measured in months of its payment. The second part is a percentage of what the borrower still owes on other financed properties. The total is the liquid money the borrower must still hold after closing.

The rules here come from Fannie Mae's Selling Guide topic [B3-4.1-01, Minimum Reserve Requirements](https://selling-guide.fanniemae.com/sel/b3-4.1-01/minimum-reserve-requirements). It defines reserves as the number of months of the qualifying payment (principal, interest, taxes, insurance and association dues, or PITIA) that the borrower could pay from financial assets left after closing. Non-QM and portfolio lenders may use a different method, such as a set number of months per property, so check the program before applying this one.

### The two parts in a sentence each

- **Subject property reserve.** A number of months of PITIA on the new loan, set by DU or by the Eligibility Matrix for manual underwriting.
- **Other financed property reserve.** A percentage of the combined unpaid principal balance on the borrower's other financed properties.

### Who calculates it

For loans run through Desktop Underwriter, DU sets the reserve amount, including the extra layer, and the findings show it. For manually underwritten loans, the topic points to the Eligibility Matrix for the minimum. Either way, the broker should run the figure before submission so the borrower is not surprised.

## Which mortgage balances count toward the financed property reserve?

The financed property reserve counts the unpaid principal balances of mortgages and HELOCs on the borrower's other financed properties. It leaves out the loan on the property being bought or refinanced, the loan on the borrower's principal residence, properties sold or pending sale, and any account being paid off at or before closing.

### Included

- First mortgages on rental homes and second homes the borrower owns
- HELOC balances on those same properties
- Loans on financed properties held jointly with the borrower

### Left out

- The mortgage on the subject property
- The mortgage on the principal residence
- Properties sold or under contract to sell
- Accounts paid off by closing, or omitted from the online application in DU

### Why the principal residence is left out

The rule targets portfolio risk. A borrower with several rentals can face several vacancies at once. The home they live in is treated differently because it is not a source of rental income that could stop. That is also why paying down a rental's mortgage before applying lowers the reserve, while paying down the home mortgage does not.

## The 2, 4 and 6 percent tiers by financed property count

The 2, 4 and 6 percent tiers depend on how many financed properties the borrower has. Under Fannie Mae's rule, one to four financed properties use 2% of the aggregate unpaid balance, five to six use 4%, and seven to ten use 6%, with the top tier available only through DU.

| Financed properties (count) | Percentage of other properties' unpaid balance | Underwriting |
| --- | --- | --- |
| 1 to 4 | 2% | DU or manual |
| 5 to 6 | 4% | DU or manual |
| 7 to 10 | 6% | DU only |

### What "financed properties" means here

The count is of properties, not every property owned and not every loan. Fannie Mae's topic on [multiple financed properties for the same borrower, B2-2-03](https://selling-guide.fanniemae.com/sel/b2-2-03/multiple-financed-properties-same-borrower) counts one- to four-unit properties where the borrower is personally obligated on the mortgage, and a two-unit building counts once. The principal residence counts if it is financed, and the subject transaction counts too, even though neither balance is part of the percentage. A property owned free and clear carries no mortgage obligation, so it adds nothing.

### How a tier change moves the number

Crossing from four financed properties to five doubles the percentage. A borrower with four financed properties and $600,000 in other balances needs $12,000 at 2%. Add a fifth financed property and the same balances need $24,000 at 4%. Those figures are examples, but the jump is real, and it explains why some investors pay off a small mortgage before buying the next property.

## Assets that satisfy the extra financed property reserve

The extra financed property reserve can be met with the same assets as any Fannie Mae reserve: money the borrower can reach after closing. Checking and savings, stocks, bonds, mutual funds, certificates of deposit, money market funds, trust accounts, the vested part of a retirement account and the cash value of a vested life insurance policy all qualify under B3-4.1-01.

### What the topic rules out

The same topic excludes unvested money, borrowed money, unlisted stock, contributions from interested parties or the lender, and cash-out proceeds from the subject property, while eligible gifts (not gifts of equity) may help. The full list, with the gift and retirement conditions, is in [which accounts count toward mortgage reserves](/blog/mortgage-reserve-requirements#which-accounts-count-toward-mortgage-reserves).

### Liquidity, not net worth

An investor with ten rentals may have a large net worth and little cash. Equity in the rentals does not count. The post on [liquid assets for a mortgage](/blog/liquid-assets-for-mortgage) explains how lenders sort accounts by how quickly they can become cash, which is the question this reserve really asks.

### Business accounts and entity-held cash

Many investors hold rental cash in an LLC account. Whether that money counts depends on the borrower's ownership and the lender's rules on business assets. If the same investor also borrows for the business, a commercial lender will ask its own questions about that cash. The post on [proof of liquidity for a business loan](/blog/proof-of-liquidity-for-business-loan) covers that side, and the same dollars should not be promised to two lenders at once.

## Financed property reserves when the subject is a primary home

Financed property reserves under DU apply when the borrower has multiple financed properties and the loan is for a second home or an investment property, according to Fannie Mae's topic. An investor buying a primary residence does not owe the percentage layer, though DU can still ask for reserves on its overall risk assessment. The findings decide.

### Why this edge case matters

Brokers who work mostly with investors sometimes apply the percentage to every file out of habit. On a primary home purchase, that can overstate what the borrower needs and lead to a smaller loan amount than necessary. Read the DU findings for the actual figure.

### Manual underwriting and non-QM

Manually underwritten loans follow the Eligibility Matrix, and non-QM programs follow their own guides. A non-QM lender may ask for months of payments on every financed property whatever the subject's occupancy. When placing a file outside DU, ask the lender for its reserve worksheet.

## Counting mistakes that inflate or hide the financed property reserve

Counting mistakes in the financed property reserve usually come from the real estate schedule on the application. A property left off makes the reserve too small and surfaces later on the credit report. A property counted twice, or a sold property left on, makes it too large and can kill a file that should qualify.

### Mistakes that make the reserve too small

- Leaving off a financed property held in an LLC when the borrower signed the mortgage personally
- Forgetting a HELOC balance on a rental
- Counting a property as sold when the sale has not closed

### Mistakes that make the reserve too large

- Including the subject property's loan in the balance total
- Including the principal residence's loan
- Keeping a loan that will be paid off at closing
- Counting a paid-off property as financed

### Documenting the balances

The underwriter will match the schedule against the credit report and mortgage statements. Asking the borrower for every mortgage statement up front saves a condition. When an electronic verification of the accounts is used, the lender needs the borrower's consent first; the post on the [borrower authorization form](/blog/borrower-authorization-form) explains what that consent covers.

## A six-property investor's reserve figure worked out

A six-property investor's reserve figure combines months of payments on the new loan with 4% of the other financed balances. The numbers below are invented for illustration and follow Fannie Mae's structure. The DU findings on a real file would set the months and confirm the total.

### The borrower's properties

| Property (example) | Status | Unpaid balance |
| --- | --- | --- |
| Primary residence | Financed | $310,000 (left out) |
| Rental A | Financed | $145,000 |
| Rental B | Financed | $122,000 |
| Rental C | Financed | $98,000 |
| Rental D | Financed, HELOC | $40,000 |
| Rental E (subject, being bought) | Financed | $260,000 (left out) |
| Rental F | Paid off | Not financed |

### The calculation

1. **Count financed properties.** Primary, A, B, C, D and E are financed: six. Rental F is paid off and does not count.
2. **Pick the tier.** Six financed properties use 4%.
3. **Add other balances.** $145,000 + $122,000 + $98,000 + $40,000 = $405,000.
4. **Apply the percentage.** 4% of $405,000 is $16,200.
5. **Add the subject reserve.** Suppose DU asks for six months of PITIA at $2,100 a month: $12,600.
6. **Total.** $16,200 + $12,600 = $28,800 in reserves after closing.

### Checking the borrower can meet it

The borrower shows $41,000 in brokerage and savings after closing funds. That clears the $28,800 with room to spare. If $15,000 of that sat in a retirement account that can be accessed only on job termination, it would drop out, leaving $26,000 and a shortfall.

Reserve figures like this rest on balances that have to be proven from statements. [TrueBankFlow](/get-started) lines up months of deposit-account statements and flags large deposits, so the balance you count is one you can trace.
