Investors ask this all the time online: pay cash or finance the next rental? Most answers skip a key fact. Fannie Mae sets a hard cap on how many financed properties one person can carry. Hitting that cap is a real reason many investors end up in DSCR loans. It is not just a sales pitch.

The rule, in plain terms

Fannie Mae’s Selling Guide, section B2-2-03, caps most investors at 10 financed properties total. That count includes every property with a mortgage, even the home you live in. So an investor with a primary home and 9 financed rentals is already at the cap.

The rules do not wait until property 10 to get harder. They step up at property 5. Once you own 5 or more financed properties, most conventional lenders ask for more. They want a higher minimum credit score than a standard loan needs. They also want extra cash reserves, commonly reported as 6 months of mortgage payments, for every property you already own. That reserve rule applies to each property you hold, not just the new one.

Number of financed properties (including your home) What applies
1 to 4 Standard conventional rules on documents and credit
5 to 10 Stricter rules: a higher minimum credit score, extra reserves per property, and other added conditions
11 or more Conventional financing is not available under this rule at all

The rules get stricter well before you hit ten. Past ten, conventional financing stops being available at all.

Read this table as a guide to which tier you fall in. It does not decide whether you personally qualify. Fannie Mae updates the exact reserve and credit-score numbers now and then, so check the Selling Guide section above for the current figures before you plan around them.

What the reserve rule actually costs

The reserve rule sounds small until you do the math. Say your typical rental has a $2,000 monthly payment. Six months of reserves for that one property is $12,000. That cash has to sit in the bank, untouched, on top of your down payment and closing costs. Now hold five rentals at that same payment level. The reserve requirement for those five alone adds up to about $60,000. That cash has to stay ready, not just be raisable if needed.

This is why the rule bites well before an investor reaches 10 properties. The reserve and credit-score rules at the 5-property mark are often the harder wall to climb, long before the 10-property ceiling itself.

Why this pushes investors toward DSCR

DSCR loans are Non-QM. That means they are not sold to Fannie Mae or Freddie Mac. Fannie’s 10-property rule only counts properties financed through the conventional system, so a DSCR loan does not add to that count at all. An investor who has hit the cap, or who does not want to keep meeting the reserve rule at every new property, can keep growing through DSCR loans instead. These loans sit outside Fannie’s rule entirely.

This is a real, structural reason to use DSCR loans, not a soft sales line about being “more flexible.” If your plan is to own more than 10 financed properties, or if the reserve rule at properties 5 through 10 is already a strain, DSCR loans stop being optional. They become the path that keeps working. See what is a DSCR loan for how these loans qualify the property instead of you.

Why the guide sets a limit at all

It is worth understanding why this rule exists, not just what it says. Fannie Mae buys loans from lenders and holds the risk that a borrower stops paying. A borrower with one mortgage missing a payment is a manageable problem. A borrower with ten mortgages hitting trouble at once, say during a slow rental market or a job loss, is a much bigger one, spread across ten separate loans and ten separate properties. The reserve and credit-score rules at the 5-property mark, and the hard stop at property 10, are built around that risk, not around punishing investors for owning several properties.

That context matters for how you read the rule. It is not a penalty for being a successful investor. It is a risk limit written into a system built mainly around one-property, one-borrower loans. DSCR lenders, by contrast, are pricing each loan against the specific property’s own income, which is part of why they are comfortable extending credit past a point where the conventional system stops.

Do not reach for DSCR too early

None of this means a new investor should skip conventional loans for their first rental or two. The 10-property limit, and its stricter rules at property 5, will not affect you for years if you are buying one or two properties at a time. While you are under the limit and can document your income, conventional pricing is very likely still cheaper. See DSCR loan vs. conventional investment loan for the real numbers on that side. Reaching for DSCR before you need it means paying a real cost, a reported rate premium, to solve a problem you do not have yet.

What this means for you

Count your financed properties honestly, including your own home. Under 4? This rule is not something to plan around today. Near 5? Start saving for the reserve rule now, since it applies to every property you already hold, not just the next one. Near or past 10? Conventional financing is closing off as an option. DSCR loans are the realistic path to keep buying, worth shopping even at a rate premium over what conventional financing would have cost.
