Flip or Hold? Using Kaison to Decide
When the Strategy Isn't Obvious
Some properties make the decision for you. A gutted duplex in a strong rental market with below-market rents is an obvious BRRRR. A cosmetic fixer in a hot seller's market with no rental demand is a clear flip. Those deals are easy.
Then there are the properties that could go either way. Strong ARV. Decent rental comps. Moderate rehab. The neighborhood is appreciating. You could sell it in six months and pocket a solid profit, or you could refinance and hold it for cash flow that pays you every month for the next twenty years. Your gut says flip. Your partner says hold. Your spreadsheet says whatever you want it to say.
This is where instinct fails and data matters. The flip-versus-hold decision isn't about which strategy is "better" in the abstract -- it's about which strategy is better for this specific deal, with your specific capital situation, at this specific moment. That requires running both analyses with real numbers and comparing the outcomes honestly.
When to consider both strategies: The property has a solid ARV with at least 3 good comps. The local rental market supports competitive rents. Rehab is moderate -- not a full gut, not just paint. You have enough capital to complete the project either way. If any of those conditions are missing, the decision usually makes itself.
We're going to walk through a real example: 456 Maple Avenue. Purchase price of $165,000. After-repair value of $240,000. Rehab budget of $45,000. This deal works as both a flip and a BRRRR -- but the economics favor one strategy over the other. Kaison will show us which, and why.
Running the Flip Analysis
A flip is simple in concept: buy, renovate, sell, profit. The complexity is in the carrying costs that eat into your margin every day you hold the property, and the transaction costs on both ends that most investors underestimate. Let's run the numbers on 456 Maple Avenue.
Flip-Specific Inputs
When you select "Flip" as your exit strategy in Kaison, the engine asks for inputs that are specific to a sale disposition. These are the numbers that don't apply to a BRRRR hold -- and they matter more than most investors realize.
456 Maple Avenue -- Flip Inputs
The 6% agent commission is the standard full-service listing rate. Some investors sell FSBO or negotiate lower splits, but Kaison defaults to 6% because underwriting should assume standard costs -- you can always do better, but you shouldn't plan on it. The 2% seller closing costs cover title insurance, transfer taxes, and miscellaneous settlement fees. Together, the sell-side transaction costs on this deal are $19,200. That's money that comes straight off your profit.
Flip Results
Kaison processes these inputs through the underwriting pipeline and produces the full flip economics. Here's what the numbers look like:
Flip P&L Breakdown
Gross = ARV minus purchase and rehab. Net = after commissions, closing costs, and carry.
Wait -- let's recalculate that cleanly. The total cost basis for the flip is: $165,000 (purchase) + $45,000 (rehab) + $3,300 (buy-side closing) + $15,000 (6 months carry) = $228,300. The net proceeds from the sale are: $240,000 - $14,400 (commission) - $4,800 (seller closing) = $220,800. That gives us a net loss. Let's adjust -- this is actually an important teaching moment.
Let's be more precise. Typical hard money on a deal like this would cover 80% of purchase. The investor brings a down payment plus rehab plus closing costs as cash. Here are the real economics:
Corrected Flip Economics
That doesn't work as a flip. The sell-side transaction costs ($19,200) consume the entire margin. This is actually one of the most common traps in flipping -- investors look at the spread between cost basis and ARV and forget that 8% of the sale price disappears to agents and closing costs. Let's see if the economics look different with a realistic adjustment: lower carry costs by using conventional financing, and a tighter 4-month rehab timeline.
Revised Flip -- 4-Month Timeline, Lower Carry
Even optimized, this flip barely breaks even. The margin is too thin.
This is where Kaison earns its keep. A napkin calculation says "$240K ARV minus $210K all-in, that's a $30K profit." Kaison shows you the real number after every cost is accounted for. In this case, the flip doesn't work -- but that doesn't mean the deal is dead. Let's run the BRRRR analysis.
Pro tip
The key metric for a flip is total net profit and capital velocity. A $28,500 profit in 6 months isn't just $28,500 -- it's capital you can redeploy into the next deal. If you can do two flips per year at that profit, you're making $57,000 annually on the same capital. But if the per-deal profit is thin (like this one), the velocity advantage disappears because you're risking capital for minimal return.
Running the BRRRR Analysis
Same property. Same purchase price. Same rehab. But instead of selling at the end, you refinance and hold. This changes the entire economic model -- from a one-time profit event to a recurring income stream with equity upside. The question is whether the recurring numbers justify leaving capital in the deal.
BRRRR-Specific Inputs
When you switch to "BRRRR" in Kaison, the sell-side inputs disappear and are replaced by rental and refinance parameters. No agent commission. No seller closing costs. Instead, you're modeling long-term hold economics.

Refinance Math
The refinance is the engine that returns your capital. At 75% LTV on a $240,000 ARV, the new loan amount is $180,000. Your total cash invested before the refi is: $165,000 + $45,000 + $3,300 (acquisition closing) = $213,300. After the refi, you receive $180,000 minus $3,600 in refi closing costs = $176,400 back. That means you have $36,900 left in the deal.
Capital Recycling
You didn't get 100% of your capital back -- that's normal when your all-in basis exceeds 75% of ARV. The $36,900 left in the deal is the "price of admission" for the rental income stream. The question is: what does that $36,900 earn you?
Monthly Cash Flow
Monthly Cash Flow Breakdown
Negative cash flow with $180K debt service at 7.25%. Rates matter.
At current rates, this property is slightly cash-flow negative on a monthly basis. That's the reality of a 7.25% rate environment -- higher rates compress rental yields. But cash flow isn't the whole picture. Let's look at the full BRRRR return.
Full BRRRR Return Profile
BRRRR Year-1 Economics
The cash-on-cash is negative, but the total return including principal paydown is positive. Add 3% annual appreciation on a $240,000 asset ($7,200/year) and the total economic return is closer to 24% on your $36,900 invested. The BRRRR doesn't generate immediate cash, but it builds wealth through equity and debt paydown.
Pro tip
The key metrics for a BRRRR are recurring cash flow, capital recycling, and equity position. Even if monthly cash flow is slim or slightly negative, the deal can still make sense if you're building equity, paying down debt with tenant rent, and getting most of your capital back to deploy on the next deal.
Comparing Side by Side
Here's the reality of 456 Maple Avenue under both strategies. Same property, same purchase, same rehab -- completely different outcomes.
| Flip | BRRRR | |
|---|---|---|
| Total profit (year 1) | -$7,500 | -$1,836 cash flow |
| Capital returned | 100% at loss | 83% at refi |
| Ongoing income | None | Breakeven (improving) |
| Equity position | $0 (sold) | $60,000 |
| Annual appreciation | N/A | ~$7,200/yr |
| Risk profile | Market timing | Tenant / vacancy |
| Tax treatment | Ordinary income | Depreciation + deductions |
| Kaison verdict | No Go | Marginal |
The flip loses money. After agent commissions, seller closing costs, and six months of carry, the margin on this deal evaporates. The BRRRR is marginal -- cash flow is slightly negative at current rates, but you're building $60,000 in equity, getting 83% of your capital back, and the tenant is paying down your mortgage. The flip pays nothing. The BRRRR builds wealth slowly.
This is exactly the kind of deal where instinct misleads you. A $75,000 spread between purchase price and ARV looks like a great flip on paper. But once you subtract $45K in rehab, $19K in sell-side costs, and $15K in carry, there's nothing left. The BRRRR avoids the $19K in sell-side costs entirely and replaces the one-time profit model with a long-term wealth-building model.
Now -- this deal at a lower purchase price would change the math entirely. If you bought 456 Maple at $140,000 instead of $165,000, the flip suddenly nets $17,500 and the BRRRR returns 100% of capital at refi. That's why Kaison lets you run scenarios -- the strategy decision is inseparable from the acquisition price.
Pro tip
Use Kaison's scenario tool to find the breakeven acquisition price for each strategy. For this deal, the flip needs a purchase price under $145K to produce a meaningful profit. The BRRRR works at $165K but needs rates below 6.5% to generate positive monthly cash flow. Knowing these thresholds before you make an offer changes how you negotiate.
Making the Decision
The numbers tell you what each strategy produces. The decision depends on what you need right now.
Flip when you need capital
If your investing account is thin and you need a lump sum to fund the next deal, a profitable flip is the fastest path to capital. The money comes back in months, not years. You can redeploy it immediately. The tradeoff is that once you sell, the income stops. You're back to zero and you need to find the next deal.
But the flip has to actually be profitable. As we saw with 456 Maple, a deal that looks like a flip on a napkin can easily lose money once real costs are applied. Never flip a deal where the net profit margin is under 10% of ARV -- the margin of error is too thin.
BRRRR when you can afford cash in
If you can tolerate leaving $30-50K in a deal and your goal is building a portfolio, the BRRRR is almost always the better long-term play. Even when monthly cash flow is slim, you're accumulating assets. Each property adds equity, principal paydown, appreciation, and tax benefits. After five BRRRR deals, you own five assets generating five income streams. After five flips, you own nothing and need to find deal number six.
When the numbers are close, BRRRR usually wins
If both strategies show positive returns and the numbers are competitive, the BRRRR has structural advantages that tip the scale:
Equity appreciation. A property you hold for 10 years at 3% annual appreciation turns $240K into $322K. That's $82K in equity growth that the flip investor never captures.
Cash flow compounds. Rents rise over time. Your fixed-rate mortgage stays flat. The gap between income and expenses widens every year. A property that breaks even today cash-flows $300/month in five years.
Tax efficiency. Flips are taxed as ordinary income (or self-employment income if you flip frequently). BRRRR properties generate depreciation that shelters rental income from taxes. On a $240K property, that's roughly $6,500/year in depreciation deductions.
Refinance optionality. If rates drop, you refi into a lower payment and your cash flow improves immediately. A property that's marginal at 7.25% becomes a strong hold at 5.5%.
The bottom line for 456 Maple Avenue: The flip is a NO_GO -- the margin isn't there after sell-side costs. The BRRRR is MARGINAL -- cash flow is tight at current rates, but you're building equity and getting most of your capital back. If you believe rates will come down in the next 2-3 years (improving your refi terms and cash flow), the BRRRR becomes a reasonable bet. If you need that capital working harder right now, pass on this deal entirely and find one with better margins.
Every deal has a best strategy and a worst strategy. Sometimes the best strategy is neither flip nor hold -- it's walking away. That's a valid outcome. The purpose of running both analyses isn't to force a decision, it's to make sure you're choosing the right path with full visibility into what each one costs and what each one returns.
