Every lender runs your deal through the same four filters. They are called the 4 Cs of underwriting: collateral, capacity, credit, and character. A bank weights them one way. A private fix and flip lender weights them another. On a flip, the property and your track record decide the loan long before your credit score does, and knowing that order changes how you package a deal.

This guide breaks down what each C means, how a private lender reads it, and what you can do to make every C work in your favor.

We are Evergreen Capital, a private real estate lending fund operating in Lexington, Cincinnati, Louisville, Columbus / Phenix City, and Montgomery. We are members of the American Association of Private Lenders. Our affiliated acquisitions company, Rapid Fire Home Buyers, has bought and resold 2,000+ residential properties over six years, including 503 in 2025 alone. We lend on the kind of deals we have done ourselves.

The 4 Cs of underwriting are collateral, capacity, credit, and character. They are the four factors a lender weighs to decide whether to fund a loan, and they are the same four factors whether you are buying a primary residence or a vacant flip.

What changes is the weighting. As Colorado private lender Montegra explains in its breakdown of the 4 Cs of private capital underwriting, a bank treats some of these as hard gates, so a low credit score in one box can mean automatic rejection. A private lender looks at the bigger picture, where a weakness in one C can be offset by strength in another.

For a fix and flip, that reordering is the whole game. The bank leads with your personal credit and income. A private lender leads with the property and your operating record. Underwriting is a defined discipline in professional private lending, covered alongside legal documentation and loan servicing in AAPL’s Certified Private Lender Associate curriculum, and the discipline starts with the asset.

Here is the order a fix and flip lender actually reads them in:

• Collateral. The property and the deal math. Most important.
• Capacity. Whether the project can repay the loan, and whether you have the cash to carry it there.
• Credit. Your credit profile, read as a direction rather than a gate.
• Character. Your track record and how you communicate.

The next four sections take them in that order.

Collateral is the property itself, and on a fix and flip it is the single most important C. A private lender underwrites the asset first because the asset is what secures the loan. If the deal goes sideways, the property is what gets the lender paid back.

The collateral question comes down to three numbers:

• ARV (after repair value).What the property is worth once the renovation is done, based on comparable renovated sales nearby. This is the most important number in the file.
• LTV / LTARV (loan to value, against ARV). Most fix and flip lenders cap the loan at 70 to 80% of ARV. We cap at 75% of ARV. That ceiling is the equity cushion that protects both of us.
• LTC (loan to cost). The loan measured against your total cost, meaning purchase price plus rehab. We fund up to 90% of the purchase and 100% of the rehab as long as the total stays under the ARV cap listed above.

Take a representative Cincinnati flip we would fund. Purchase price $135k, rehab budget $42k, so $177k all in. Comps put the ARV at $245k. We fund up to 75% of that $245k, which is $183,750, enough to cover the purchase and most of the rehab while keeping a real equity cushion underneath the loan. You bring the gap plus your liquidity.

Two things make or break the collateral C. The first is comp accuracy. A 10% overstatement of ARV can erase the entire profit margin, which is why RCN Capital recommends checking 3 to 5 recent renovated comps and building in a 10 to 15% renovation contingency. The second is a realistic scope of work. We have walked, bought, and resold 2,000+ houses in these markets, so we know what a kitchen actually costs and what a roof line is hiding. A third-party appraisal is required as part of the loan process. We order and coordinate it so underwriting can keep moving in parallel with title and docs, instead of sitting in a bank-style queue.

Capacity is the ability to repay. For a homeowner, that means a paycheck and a debt-to-income ratio. For a flip, it means two things: the project has to repay the loan, and you have to have the cash to carry it there. The loan gets repaid when you sell or refinance, not out of your monthly salary, so a fix and flip lender reads capacity as your exit plus the money standing behind it.

Start with the exit:

• What is the exit, and is it real? A sale at the ARV the comps support, or a refinance into a rental at a debt service coverage ratio that works. If the exit is “I’ll figure it out,” the capacity C is weak no matter how good the purchase price looked.
• Is the timeline honest? A flip you can finish and sell in 9 months is a stronger file than the same flip stretched to 13. Time is a cost on every flip, and on a bridge loan it is your cost. If the project runs long, we extend at 1 point per 3 months, up to two extensions, but a tight timeline is a stronger capacity story.

Then the cash. A lender funding 75% of ARV needs you in the rest of the deal, because a borrower with their own money in a project behaves differently than one with nothing to lose. That shows up in three places:

• Your down payment, or cost contribution. With financing up to 90% LTC, you bring the rest of the cost. That is your money at risk, sitting behind the loan.
• Reserves after closing. We look for at least 10% of the loan amount in liquidity post-close. Our loans are 12-month interest-only with a balloon, so you cover the monthly interest while the property is non-income-producing. Reserves are the cash that carries the project when a draw is in process or a timeline slips. We underwrite to whether your reserves can carry the carry.
• A funded rehab budget. Draws reimburse completed work, so you front the first stage of the renovation and we release funds against milestones. Every draw is a flat $150 fee.

The cash side is a safety net for you, not just for us. The investor who goes into a flip with no reserves is the one who stalls mid-rehab when something behind a wall costs more than the scope said it would. Reserves are what let you absorb the surprise and keep moving. They are the difference between a delay and a dead deal.

Capacity is also where experience quietly shows up. An operator who has carried six flips through to sale has proven they can manage a renovation budget, a contractor, and a holding period. That track record is also part of the character C, which is the point Montegra makes about how the Cs overlap rather than sit in separate boxes.

Credit is its own C, but it is the lightest of the four on a fix and flip. We read it as a direction rather than a gate. A bank leads with your FICO and treats a low score as an automatic decline. We pull credit to understand the borrower, not to rank you against a cutoff, because the deal and your track record have already done most of the talking by the time we get to the score.

Here is what most lenders miss, and what we account for. Experienced operators run their business on personal credit. Materials, contractor deposits, holding costs, all of it goes on the cards, and that spikes utilization. High utilization drops your FICO even when you pay every balance in full every month. So the number in front of us is often a snapshot of a working capital cycle, not a measure of whether you pay your debts. We read past it.

Rough guide to how we see the score:

• 680+ is ideal. Clean file, no questions.
• 650+ is acceptable with conditions. We will want context on utilization or any recent dings, and the deal and track record carry more of the weight.
• Under 600 is where it becomes a real problem. Not an automatic no, but it has to be offset by strong collateral and a real track record, and we will talk through what happened.

One thing to be clear about: we only run credit after you apply, and it is a soft pull that does not touch your score. We never pull credit to prequalify. Prequalifying takes about 60 seconds with no credit check at all, so you can see where a deal stands before anything hits your report.

Character is who you are as a borrower: your track record and how you behave through a deal. A bank reduces character to a credit score. A private lender reads it wider, because we are entering a business partnership with you, not just pulling a report. Credit gets its own C, just above. Character is the part of a borrower a score cannot show.

For a fix and flip lender, character has two parts:

• Track record. This is the heaviest part. We work with experienced operators, and our floor is 3 completed flips in the last 36 months. A finished flip or BRRRR on your record tells us you can take a property from purchase to profitable sale. First-timers can still get there with an experienced operator co-sponsor.
• Communication. This is the C most borrowers underrate. The borrower who answers the phone during underwriting is the borrower we trust to answer it when a payment is due. Montegra calls communication the unofficial fifth C, and we agree. We have watched a borrower lose a deal because their prior lender went silent, not because the deal was bad.

That last point is worth sitting with. Time kills all deals. The lender you cannot get on the phone is the lender that loses your deal, and the borrower a lender cannot reach is the borrower who gets the cautious answer. Character is responsiveness as much as resume.

No single C approves a loan. The 4 Cs work as a system, and the most useful thing to understand about a private lender is that strength in one can offset weakness in another. A bank rejects on a single failed gate. We read the whole file.

A few real trade-offs:

• Strong collateral (a 65% LTV deal with a deep equity cushion) can carry a borrower with only 2 completed flips.
• A long track record (15 flips, every one finished on time) can carry slightly lighter reserves.
• Strong collateral and real cash in the deal can offset a credit score that high utilization has pushed down.

What cannot be offset is a deal with no equity cushion and an operator with no record and no reserves. When every C is weak, there is nothing left to lend against.

Here is the 30-second version we run on every borrower call. It is the same framework, scored fast:

A file that is mostly green funds fast. A file with one yellow is a conversation. A file with reds in several rows is usually a different product than ours, and we will tell you that honestly rather than waste two weeks of your time.

Evergreen Capital underwrites the 4 Cs through an operator’s eyes, because we have been the operator. We have borrowed over $10M on our own deals, and Rapid Fire Home Buyers has acquired and resold 2,000+ properties in the exact markets we lend in. We are the borrower we serve, and that shapes how we read every C.

Three things fall out of that:

• The collateral C is judged by people who know the block. When we look at an ARV in Hamilton County or Fayette County, we are not guessing from a spreadsheet three states away. We have bought and sold houses on those streets. That is local underwriting. Paired with an appraisal we coordinate as part of the process, the file keeps moving without a bank-style bottleneck.
• The character C is judged by people who pick up the phone. When you talk to us, you are talking to the person who approves the loan. No committee, no out-of-state desk, no relay to “the underwriter.”
• The whole file moves at the speed of your deal. Pre-qualify in 60 seconds, get a term sheet in 24 to 48 hours, and close in 10 to 14 days, because underwriting runs in parallel with your document upload, not after it.

We are not the cheapest money. We compete on certainty of execution, which is exactly what the 4 Cs are built to measure. If you want to see how the Cs map to a real loan, our borrower programs lay out the parameters: up to 75% of ARV, up to 90% LTC, 13%, 2 points, $50k to $500k, 6-month interest-only, no prepayment penalty.

What are the 4 Cs of underwriting? The 4 Cs are collateral, capacity, credit, and character. Collateral is the property and the deal math, capacity is whether the project can repay the loan and whether you have the cash to carry it there, credit is your credit profile read as a direction rather than a gate, and character is your track record and communication. Every lender weighs the same four, but a private fix and flip lender weights collateral and character most heavily.

Which C matters most for a fix and flip loan? Collateral. A fix and flip loan is secured by the property, so the deal math (ARV, LTV, and LTC) carries the most weight. A private lender caps the loan at a percentage of ARV, often 70 to 80%, to build an equity cushion that protects the loan if the project goes sideways. Your track record is a close second.

Do fix and flip lenders check your credit score? Yes, but as a direction rather than a gate, and only after you apply. A private lender pulls credit with a soft inquiry that does not affect your score, then reads it for the story behind the number. Experienced operators often run business expenses on personal credit, which spikes utilization and pushes FICO down even when every balance is paid. Evergreen sees 680+ as ideal and 650+ as acceptable with conditions, but a strong deal and a solid track record carry more weight than the score. Prequalifying never requires a credit pull.

Can a strong deal make up for weak credit or limited experience? Often, yes. Private lenders read the whole file rather than rejecting on a single failed gate. Deep equity in the property can offset a thinner track record, and a long, clean operating history can offset lighter reserves. A credit score pushed down by high utilization is one of the easier things for a strong deal to offset. What cannot be offset is weakness across every C at once.

How is private lender underwriting different from a bank? A bank leads with your personal credit and income and treats them as hard gates. A private lender leads with the property and your operating record, and can offset a weakness in one area with strength in another. That is why a private lender can fund a vacant, uninhabitable property for an experienced operator that a bank would decline outright.

The 4 Cs are not a lender’s secret. They are a checklist you can run yourself before you ever submit a file. Score the collateral (is there a real equity cushion under 75% of ARV?), the capacity (is the exit real, the timeline honest, and do you have the gap plus reserves?), the credit (is your score a true picture or a utilization snapshot?), and the character (track record and a phone you actually answer). A deal that is green across the board is a deal that funds fast.
