You are looking at two listings. One is a four-unit at $600,000. The other is a five-unit two blocks over, same price, same condition, one more door. You run rent per unit and the five-unit wins. You assume the loan is the same loan with a bigger rent roll behind it.
It is not the same loan. On the wholesale DSCR rate sheet I price from in Sparta, New Jersey, dated September 8, 2026, the one-to-four unit program floors at 6.375% and the five-to-eight unit program floors at 8.375%. That is a 200 basis point gap in the minimum note rate between a building with four doors and a building with five.
The fifth door does not add a surcharge to your four-unit loan. It moves you onto a different program with a different rate ladder, lower leverage, a higher credit bar, a minimum loan size, and a lower cash-out ceiling. That has to be priced before you write the offer, not discovered at application.
Nothing on this site has covered unit count until now. If your question is how many properties you can finance, that is a different wall and it is covered in Scaling Past the 10-Property Wall. This post is about what happens inside one property when the unit count crosses four.
Two Programs, Not One Program With a Surcharge
Here is what the two programs look like side by side. One lender, one sheet, one day. The lender is deliberately not named and the rate ladders are not reproduced.
| 1–4 unit | 5–8 unit | |
|---|---|---|
| Floor rate, fixed and ARM | 6.375% | 8.375% |
| Maximum CLTV | 80% | 75% (70% on loans $1.5M–$2M) |
| Credit tiers priced | down to 600–619 | 740+ and 720–739 only |
| Minimum loan amount | pricing begins under $150,000 | $400,000 |
| Cash-out ceiling | through 75% CLTV | 65% CLTV |
| Prepay buyout, no penalty | 1.000 to 1.250 points | 1.750 to 2.250 points |
| Maximum price | 103.000 at a 60-month penalty | 100.000 at 12+ months |
| Payment history | standard | 0x30x12 on subject property and primary residence |
Read the table as a structure, not as a set of adjustments. A pricing adjustment sits on top of a program. A borrower with a lower score pays a little more on the same grid. That is not what is happening here. The five-to-eight unit program has its own floor, its own leverage cap, its own credit tiers, its own minimum loan size and its own prepayment pricing. The fifth door does not move you down the grid. It moves you to a different grid.
The floor is the minimum note rate on the program. It is not a quote. A real borrower prices above the floor after credit, leverage and coverage adjustments, on either program. So the 200 basis point gap is the best case, not the typical case. The honest version of the claim is that at best, the fifth unit costs you two points of rate.
The pattern holds on a second product. The same sheet carries a low-leverage equity program with no credit-tier grid at all, and it splits the same way: a 9.75% floor at one-to-four units against 10.99% at five-to-eight. That is a 124 basis point gap on a product built for a completely different borrower. Two independent programs on one sheet, same day, both pricing the fifth door as a different asset. The finding does not rest on one product.
The Four Things That Change Besides the Rate
The rate gap is the headline. It is not the part that stops most deals. Four other things move when you cross from four units to five, and any one of them can end a file before the rate ever matters.
Leverage drops from 80% to 75%. On a $600,000 purchase that is $30,000 more cash at closing, before you touch the rate. On the five-to-eight program the ceiling steps down again to 70% on loans between $1.5 million and $2 million. If you have been modeling 20% down on five-units because that is what your four-units took, your equity requirement just went up by a quarter.
The credit bar moves to 720. The five-to-eight program on my sheet prices two credit tiers, 740 and up and 720 to 739. That is the whole grid. Below 720 there is no worse price on the five-unit. There is no price. A borrower at 690 who can finance a four-unit all day cannot finance the building next door with one more door in it. The one-to-four program on the same sheet prices tiers all the way down to 600 to 619. So below 720 the gap between the two programs is not 200 basis points. It is the difference between a loan and no loan, and it is the sharper version of everything in this post.
The minimum loan is $400,000. The one-to-four program starts pricing well under $150,000. The five-to-eight program does not exist below $400,000. At 75% leverage that means a five-unit priced under about $533,000 cannot be financed on this program at full leverage. In the markets where five-units trade cheap, the small building that looks like the best deal on the block may not have a loan behind it at all.
The cash-out ceiling drops to 65%. The one-to-four program allows cash-out through 75% CLTV. The five-to-eight program stops at 65%. If you are a BRRRR investor planning to buy the five-unit, stabilize it and pull your capital back out, ten points of leverage is the difference between recovering your rehab budget and leaving a large piece of it in the building. On a $700,000 stabilized value that is $70,000 of cash-out that does not come back. The seasoning mechanics that decide when you can pull it are in DSCR Cash-Out Refinance and they do not get easier on the five-plus side.
Two smaller items ride along. Buying out the prepayment penalty costs 1.750 to 2.250 points on the five-to-eight program against 1.000 to 1.250 on one-to-four, so the prepayment trade is steeper on the fifth door. And the five-to-eight program prices no higher than 100.000, which means no lender credit is available on it. The one-to-four program prices up to 103.000 with a 60-month penalty, which is how a four-unit borrower covers closing costs with rate. That lever is gone at five units.
The Traced Deal
Three assumptions drive every number below. Purchase price $600,000 with 25% down on both buildings, so a $450,000 loan at 30-year amortization. Gross rent $1,300 per door, so $5,200 on the four-unit and $6,500 on the five-unit. Taxes and insurance combined at $900 a month on both, illustrative. Rates are the two program floors, 6.375% and 8.375%, so this is the best case on both sides. Coverage here is gross rent divided by PITIA, the same convention as Rents Aren't Growing, and not the vacancy and management haircut used in DSCR Ratio Explained. Same rent, same building price, same down payment, same taxes. The only thing that changes is the program.
| 4-unit at 6.375% | 5-unit at 8.375% | |
|---|---|---|
| Loan | $450,000 | $450,000 |
| Principal and interest | $2,807.41 | $3,420.33 |
| Taxes and insurance | $900.00 | $900.00 |
| PITIA | $3,707.41 | $4,320.33 |
| Gross rent | $5,200 | $6,500 |
| DSCR | 1.4026 | 1.5045 |
| Monthly cash flow | $1,492.59 | $2,179.67 |
The fifth door adds $1,300 of rent. It adds $687.09 of cash flow. The other $612.91 goes to the rate difference. Forty-seven percent of the new rent never reaches you.
That is the number to carry into the listing. The fifth unit is not $1,300 of income. It is $1,300 of rent minus the cost of crossing programs, and on this loan that cost eats nearly half of it before vacancy, before turnover, before the fifth furnace.
Both DSCRs clear the 1.25 step where pricing usually improves, so on the traced deal neither building is paying a coverage penalty. That is a feature of the assumptions, not a rule. A five-unit with a weaker rent roll at 8.375% loses coverage faster than a four-unit at 6.375%, because the higher payment is the denominator.
What It Costs at Your Loan Size
The crossing cost is the payment difference between the two floors at 30-year amortization. It scales with the loan, so the break-even scales with it. On a $450,000 loan the fifth unit has to rent above $612.91 a month just to be accretive at all. At $900,000 that number doubles.
| Loan amount | Monthly crossing cost | Annual |
|---|---|---|
| $400,000 (program minimum) | $544.81 | $6,538 |
| $450,000 | $612.91 | $7,355 |
| $500,000 | $681.01 | $8,172 |
| $600,000 | $817.21 | $9,807 |
| $750,000 | $1,021.52 | $12,258 |
| $900,000 | $1,225.82 | $14,710 |
The rule from the table: find your loan amount, take the monthly crossing cost, and compare it to what the fifth door actually rents for. If the fifth unit rents for less than the crossing cost, the five-unit is a worse building than the four-unit at the same price, no matter what the per-door average says. If it rents for more, the gap between the two is your real added income, and it is a fraction of what the rent roll shows. Every figure in this table is at the floor, so a real file prices higher on both sides and the difference can move.
The Counter-Case, and It Is Strong
In the traced deal the five-unit wins. Coverage is 1.5045 against 1.4026. Cash flow is $2,179.67 a month against $1,492.59. The extra door adds more rent than the rate adds cost, by $687.09 a month, and it does so at 25% down on both buildings.
So the post is not "avoid five-units." The five-unit is often still the better buy. It is never the same loan. The mistake is not buying it. The mistake is underwriting it at four-unit financing, finding out at application, and either eating the difference or losing the deposit.
Three things keep the counter-case honest.
One sheet, one lender, one day. Other lenders price the crossing differently. Some carry a smaller gap, some a larger one, and some do not separate the programs at all and price five-plus units as small-balance commercial with a different underwrite entirely. Ask your lender for both programs, in writing, on the same day, before you offer. If they cannot show you a five-to-eight grid, that is an answer too.
Per-door rent is rarely flat across a four and a five. The traced deal assumes $1,300 on every unit because the point is to isolate the financing. In practice the fifth door is often the smallest unit in the building, a converted basement or attic, and it rents below the average. If the fifth unit rents for $950 instead of $1,300, the break-even at $450,000 tightens from a $687 margin to a $337 margin. Underwrite the actual rent roll, not the average.
Five-plus units bring operating differences beyond the loan. Appraisers switch approaches at five units and lean on income rather than sales comparables. Insurance carriers treat the building differently and some will not write it on a residential form. Some towns run a different inspection regime for five-plus, with registration and periodic inspections that a four-unit never sees. Those are real costs. I am naming them so you price them. I am not pricing them here.
FAQ
Can you get a DSCR loan on a 5-unit property? Yes, but usually on a different program than a one-to-four unit. On the wholesale sheet I price from, dated September 8, 2026, five-to-eight unit properties run through a separate DSCR program with its own rate floor, leverage ceiling and credit tiers.
How much more does a 5-unit DSCR loan cost than a 4-unit? On that sheet the floor rate is 6.375% for one-to-four units and 8.375% for five-to-eight, a 200 basis point gap at best pricing. On a $450,000 loan over 30 years that is $612.91 a month, or $7,355 a year.
What credit score do you need for a DSCR loan on a 5-unit? On the sheet I price from the five-to-eight unit program prices two tiers only, 740 and above and 720 to 739. Below 720 there is no pricing on that program at all, while the one-to-four unit program prices down to the 600s. Tiers vary by lender; confirm on your own file.
Is a 5-unit still worth buying if the financing costs more? Often yes. In the traced example the five-unit carries higher coverage and $687.09 more monthly cash flow than the four-unit, because the extra door adds more rent than the rate adds cost. The point is to price it before you write the offer, not to avoid it.
Price Both Programs Before You Write the Offer
One recommendation. Before you offer on the five-unit, price it on the five-to-eight program and price the four-unit alternative on the one-to-four program, same day, same lender, in writing. Then run the fifth door's actual rent against the crossing cost at your loan size.
