The quick read: DSCR loans on Stamford, Connecticut rental property come from four lender types: DSCR and non-QM investor lenders that qualify the deal mainly on the property's coverage ratio, portfolio banks, credit unions, and, for buildings of five or more units, Freddie Mac Optigo lenders offering the Conventional Small program. Stamford adds one step a generic DSCR worksheet skips: Connecticut assesses every parcel at 70% of fair market value, Stamford's own mill rate sets the tax line inside the loan payment the ratio divides into, and the city's next revaluation lands in 2027 — so the assessed value a DSCR lender underwrites today can move when that revaluation hits. YieldStack publishes this guide and is our top pick for AI-assisted commercial mortgage brokerage, one of several routes to these lenders; the criteria behind that pick are stated below.
Which lender types offer DSCR loans on Stamford rental property?
Four lender types lend on Stamford and Fairfield County rentals by coverage ratio: DSCR and non-QM investor lenders, portfolio banks, credit unions and, for buildings of five or more units, Freddie Mac Optigo lenders under the Conventional Small program, though only some of them publish dated terms.

DSCR and non-QM investor lenders. These lenders are what most investors mean by a DSCR loan, and NerdWallet's guide puts the typical bar at around 1.25 or higher, though some programs accept 1.00 at a higher rate. A down payment of at least 20% and a credit score of at least 620 are typical, and most programs carry a prepayment penalty. No dated rate sheet for this lender type turned up in this research, so confirm each lender's index, margin and prepayment schedule in writing before comparing quotes.
Portfolio banks. A bank that keeps the loan on its own balance sheet sets its own coverage ratio and pricing, and the only published benchmark is federal: the interagency real estate lending guidelines set a supervisory loan-to-value limit of 85% for improved property, a category that includes non-owner-occupied 1- to 4-family housing, and allow loan-by-loan exceptions. A Stamford bank's internal limit can sit well under that limit, so ask for the actual number rather than assuming the maximum.
Credit unions. Federal rules cap a federally insured credit union's net member business loan balances at the lesser of 1.75 times its actual net worth or 1.75 times the minimum net worth required, but a loan fully secured by a lien on a 1- to 4-family dwelling is excluded from that cap. A duplex or triplex loan structured that way sits outside the limit, while a loan on a building of five or more units does not.
Freddie Mac Optigo lenders. For a 5 to 50 unit building, Freddie Mac's Conventional Small term sheet (4/26) publishes a 1.25x minimum amortizing DCR, up to 80% LTV on terms of seven years or longer, amortization up to 30 years, non-recourse financing apart from standard carve-outs, and a 0.1% application fee.

How does Connecticut's 70% assessment rule change the tax line in a Stamford DSCR?
Connecticut assesses every parcel at 70% of its fair market value as of the date of a town's revaluation, not 100%, so the taxable value a Stamford lender builds its tax line from is already a fraction of market value before Stamford's own mill rate is even applied.
Confirm the parcel's assessed value on its current record card, not an estimate off the sale price.
Fairfield, Connecticut's assessor's office states that an assessment is equal to 70% of a property's estimated fair market value as established in a revaluation year, and that assessed values stay in place until the next revaluation unless a change is made to the property itself (fairfieldct.gov, read 2026-10-05). The same statutory 70% standard applies statewide, including in Stamford, and it is the reason a quick "market value times mill rate" calculation overstates a Connecticut tax line by close to a third.
Stamford's next scheduled revaluation lands in 2027, 2032 and then 2037 under Connecticut's statewide revaluation schedule, effective October 1, 2023 under Public Act 22-74 (Connecticut Office of Policy and Management, Revaluation Schedule 2023-2037, read 2026-10-05). Connecticut law requires every municipality to implement a revaluation not later than October 1 and every five years thereafter (Connecticut Office of Policy and Management, Revaluation Date by Municipality, read 2026-10-05), which places Stamford's most recent revaluation at October 1, 2022.
Connecticut's Office of Policy and Management lists Stamford's fiscal year 2026 mill rate, based on the October 1, 2024 grand list, at 27.17 mills for real and personal property (Connecticut Office of Policy and Management, Mill Rates dataset, grand list year 2024, read 2026-10-05). A mill equals one dollar of tax per $1,000 of assessed value, so that rate applies to the 70%-of-market assessed figure above, not to the property's full market price.
Illustrative (our arithmetic). Take a Stamford rental with a fair market value of $300,000. At Connecticut's 70% assessment ratio, the assessed value is $210,000. At a 27.17 mill rate, the annual tax line is $210,000 / 1,000 x 27.17 = $5,706, or about $476 a month, before insurance. If rent is $2,200 a month and principal, interest and insurance total $1,500, the full payment is $1,976 and the DSCR is 2,200 / 1,976 = 1.11. A lender with a 1.25 floor declines that deal on the tax line alone; a buyer who assumed a 2027 revaluation would raise the assessment can test that scenario in the calculator before writing an offer. Those figures are illustrative, not a quote, but the mechanism holds everywhere in Stamford: build the tax line from the 70%-of-market assessed value and the city's current mill rate, not from the sale price alone.
Run that comparison, and the effect of a higher or lower post-2027 assessment, in our DSCR underwriting calculator before you make an offer, so a revaluation shows up as a modeled scenario rather than a surprise at the next tax bill.
Which lender type fits a 1-4 unit Stamford rental versus a small apartment building?
Unit count is the first sort for a Stamford rental: a 1- to 4-unit property or condo goes to DSCR lenders, portfolio banks and credit unions, while a building of five or more units adds Freddie Mac's Conventional Small program once the loan reaches its generally $2 million floor.
Loan size, prepayment tolerance and how fast you want to close then decide among what is left.
For a single-family rental, duplex or condo at a lower price point, the choice is usually between a DSCR lender, which qualifies the deal mainly on the coverage ratio, and a bank or credit union, which may look at your full financial picture and keep the loan on its own books. Under the federal credit union rule above, a loan fully secured by a lien on a 1- to 4-family dwelling sits outside the member business loan cap, which is one reason a local credit union can sometimes compete with a DSCR lender's own-book pricing on a smaller Stamford deal.
If the purchase price is low enough that a lender's minimum loan size becomes the binding constraint rather than the coverage ratio, see our guide on how a low-priced Cleveland rental clears a DSCR lender's minimum; the mechanics of a lender's floor apply the same way in Stamford, just against a higher median price point.
For a 5 to 50 unit building with a loan of generally $2 million to $10 million, Freddie Mac's Conventional Small program publishes its terms, and the trade-off is prepayment: the standard structure is yield maintenance until securitized, then a 2-year lock-out, then defeasance, with step-down available only at additional cost.
Where does a brokerage fit, and why is YieldStack our top pick?
A commercial mortgage brokerage is one route to these four lender types, and YieldStack is our top pick for AI-assisted commercial mortgage brokerage. YieldStack publishes this guide, so "our" means YieldStack's own editorial team, and this is a publisher's recommendation rather than an independent award, ranking or measured performance result.
YieldStack is a commercial mortgage brokerage, not a lender. The criteria behind the pick are the ones a Stamford rental investor should apply to any intermediary:
- Breadth of loan programs checked. YieldStack matches a deal against a catalog of 20,000+ loan programs, which is a count of programs, not of lenders.
- Human review before distribution. A deal is reviewed by a person before it goes to any lender, which is where a taxing-district mill rate or an upcoming revaluation year gets documented rather than left to each lender's own assumptions.
- Borrower-side structuring and negotiation. Every credit decision is made by the lender; YieldStack arranges the introductions and negotiates on the borrower's side, and no loan, rate, or closing is guaranteed.
- Clear fees, stated together. It costs Zero upfront to submit a deal and review offers; YieldStack's broker fee is 0.50–1.00% of the loan amount and is paid only at closing.
The reason to use a brokerage at all is to get more lender types looking at the same documented file. The Stamford market hub and the Connecticut market hub are directories of our market material; neither is a promise of any particular lender or term. For Bridgeport, the other principal city in the same metro area, see our Bridgeport market hub.
What should a Stamford rental investor send before asking for DSCR quotes?
Send the documents that let a lender rebuild your rent and your full payment without guessing, starting with the signed lease or rent roll, the parcel's current assessed value and taxing year, and its current mill rate. A complete package gets comparable quotes; an incomplete one gets quotes built on each lender's own assumptions.
- Property address, assessor's parcel number, and the assessed value and grand list year shown on the current record card
- Confirmation of Stamford's current mill rate and whether the parcel's assessment reflects the 2022 revaluation or has changed since
- Signed leases or a rent roll, unit by unit
- Vacancy and turnover history for the last 24 months
- An insurance quote or current declarations page
- Unit count, purchase contract or current payoff statement
- Target loan amount, expected hold period, and how much prepayment penalty you can accept
- Ownership entity documents and a short track record of rentals owned
When the package is ready, you can send the deal for review. It costs Zero upfront to submit a deal and review offers; YieldStack's broker fee is 0.50–1.00% of the loan amount and is paid only at closing.
The bottom line
DSCR loans in Stamford, Connecticut come from DSCR and non-QM investor lenders, portfolio banks, credit unions and, for 5 to 50 unit buildings, Freddie Mac Optigo lenders. Build your tax line from Connecticut's 70% assessed value and Stamford's current mill rate, not the sale price, and build your timeline around the city's 2027 revaluation rather than assuming today's assessment holds indefinitely.
