Welcome back to our series on the BRRRR method (Buy, Rehab, Rent, Refinance, Repeat). While the entire process is a systematic approach to building wealth, the B (Buy) stage is arguably the most critical step, as it is the only point in the entire investment cycle where you truly make money.
The core principle here is straightforward: If you do not buy the property at a deep enough discount, the entire system is broken. The goal of the Buy phase is not just to acquire a property, but to secure forced equity by intentionally purchasing an asset for significantly less than its value. This immediately creates a buffer or cushion that protects your investment.
The BRRRR strategy is predicated on buying properties that are unattractive to conventional buyers—often referred to as distressed or fixer-upper homes.
Traditional lenders typically require a home to be in "livable condition," meaning it must have functional plumbing, electrical, a roof without holes, and working appliances. By focusing on properties that require substantial repair, you avoid competing with retail buyers and gain the ability to buy deep enough to "create equity simply by signing on the dotted lines on the purchase."
This strategy stands in sharp contrast to traditional investing, where you might take out a loan on a move-in ready property but cannot access the equity you create through appreciation. With BRRRR, you add value before the final financing is secured, ensuring the subsequent refinance step works efficiently.
A fundamental technical concept that beginners must master during the Buy phase is proper deal analysis, often guided by the Max Allowable Offer (MAO) formula. This calculation ensures you acquire the property at a price that guarantees profitability after all expenses are accounted for.
The most effective formula cited by experienced investors is:
MAO = (After Repair Value × 75%) - (All Repairs + Holding Costs + Contingency)
ARV (After Repair Value): This is your estimate of what the property will be worth after all necessary renovations are completed. It is crucial that the ARV you use is what a property appraiser will actually use. Being conservative on this figure is essential to limit risk; if you think a house is worth $200,000, it is safer to underwrite it at $180,000 or even $160,000.
75% Multiplier (LTV): This is typically the maximum Loan-to-Value (LTV) ratio that lenders will offer for investment properties during the final cash-out refinance. By limiting your total acquisition and rehab costs to 75% of the anticipated ARV, you ensure you have enough equity to pull all your cash back out. Note: Some lenders offer 80% LTV, which would adjust your formula to ARV × 80%, giving you slightly more room. Always confirm your lender's specific LTV before running your numbers.
Repairs: This includes the full renovation budget based on a written contractor estimate after they've walked the property. Never use rough guesses—always get eyes on the property.
Holding Costs: This includes all expenses incurred while holding the property during the renovation and seasoning period:
Hard money loan or HELOC interest
Property taxes
Insurance
Utilities
HOA fees (if applicable)
Rule of thumb: Budget $500-$1,000 per month for 6-9 months of holding costs, depending on your market and property size.
Contingency Buffer (CRITICAL): Add 15-20% on top of your contractor's repair estimate. This isn't optional—it's mandatory. Rehab cost overruns are one of the top three deal-killers in BRRRR investing. Even experienced contractors miss things during initial walkthroughs.
Let's work through a real-world example:
Estimated ARV: $200,000 (but you underwrite conservatively at $185,000)
Conservative ARV for calculations: $185,000
75% LTV: $185,000 × 0.75 = $138,750
Contractor's Repair Estimate: $30,000
15% Contingency: $30,000 × 0.15 = $4,500
Total Repairs with Buffer: $34,500
Holding Costs (7 months @ $750/month): $5,250
Total Costs: $34,500 + $5,250 = $39,750
Maximum Allowable Offer = $138,750 - $39,750 = $99,000
This means you should not offer more than $99,000 for this property. If you can negotiate down to $95,000 or $90,000, even better—you're building in additional equity cushion.
The Problem: You think the property will appraise for $250,000 because you saw one comparable sale at that price, but the appraiser uses three comps and arrives at $220,000. Your refinance falls short by $22,500 (at 75% LTV).
The Solution: Always pull at least 3-5 recent comparable sales (within 6 months, within 1 mile, similar square footage and bed/bath count). Use the lowest comparable or an average of the middle three. When in doubt, underwrite 5-10% below what you think it's worth.
The Problem: Your contractor says $25,000, but once walls are opened, you discover knob-and-tube wiring, foundation issues, or mold. The actual cost becomes $38,000.
The Solution:
Always get a written, itemized bid after a thorough walkthrough
Add 15-20% contingency automatically
Have your property manager walk the property with the contractor to catch deferred maintenance
For older homes (pre-1980), budget even more conservatively
The Problem: You calculate MAO using only purchase price and repairs, forgetting that you'll pay $5,000-$8,000 in interest, taxes, and insurance during the 6-9 month BRRRR cycle.
The Solution: Create a holding cost worksheet and include:
Hard money interest (10-15% annually on the loan amount)
Property taxes (prorated for your holding period)
Insurance ($800-1,500 annually, prorated)
Utilities during vacancy ($100-200/month)
Any HOA fees
Before you analyze your first deal, you need to understand what your refinance lender will actually approve. Different lenders have different requirements, and knowing these upfront prevents wasted time and failed deals.
What LTV do you offer on investment property cash-out refinances? (75%? 80%?)
What is your seasoning requirement? (6 months? 12 months from purchase? From stabilization?)
What DSCR (Debt Service Coverage Ratio) do you require? Most lenders want 1.0-1.25, meaning monthly rent must be 100-125% of your new mortgage payment (PITI)
Do you use current appraised value or my purchase price plus rehab costs? (Most use appraised value, which is what you want)
What are your minimum credit score and reserve requirements?
What documentation do you need for the refinance? (Lease agreement? Rehab receipts? Tax returns?)
Having these answers before you buy your first property ensures your numbers will actually work when you get to the Refinance step.
If your new mortgage payment (PITI) will be $1,200/month, and your lender requires 1.25 DSCR, your rent must be at least $1,500/month ($1,200 × 1.25). This affects which deals pencil out.
Since you must buy properties that are off-market or distressed, simply looking on the Multiple Listing Service (MLS) may not be sufficient. Beginners need systems to get good leads consistently.
Establishing a relationship with an agent who understands investment strategies and off-market deal flow is vital. They can find deals before they hit the general market.
How to Find Investor-Friendly Agents:
Attend local Real Estate Investment Association (REIA) meetings
Ask other investors in your market for referrals
Interview 3-5 agents and ask: "How many investor clients do you currently work with?" and "What percentage of your deals are investment properties?"
Look for agents who own rentals themselves—they understand the numbers
What to Communicate Clearly:
Your target ARV range ($150k-$250k, for example)
Your desired condition (needs full rehab, not cosmetic)
Your cash flow goals (minimum $200/month after all expenses)
Your maximum offer formula (show them your MAO calculation)
This strategy involves proactively identifying distressed properties and contacting those owners directly.
Reality Check: This is time-intensive and has low conversion rates. Direct mail campaigns typically yield 1-3% response rates, meaning you'll send 100-300 letters to get 1-3 responses, and maybe close one deal.
Implementation:
Drive neighborhoods looking for deferred maintenance (overgrown yards, peeling paint, boarded windows)
Use tools like PropStream or DealMachine to find owner contact info
Send personalized letters or postcards (not generic "I buy houses" mailers)
Consider hiring a Virtual Assistant to make follow-up calls
Wholesalers are investors who find distressed properties, put them under contract, and assign those contracts to other investors for a fee.
Pros: Access to deals you wouldn't find yourself; no marketing costs on your part Cons: You're paying the wholesaler's fee (typically $5,000-$15,000), which reduces your margin
How to Connect with Wholesalers:
Join local real estate investor Facebook groups
Attend REIA meetings
Get on wholesaler email lists (search "[your city] real estate wholesalers")
To get the necessary repetition needed to achieve mastery, use tools like the BiggerPockets BRRRR Calculator to analyze multiple deals quickly and confidently.
Critical Mindset: You need to analyze 10, 20, or even 50 leads to find one good deal. In fact, 99% of properties are not suitable for the BRRRR method. This isn't failure—it's filtering. The investors who succeed are the ones who don't get discouraged and keep analyzing.
When buying a distressed property that needs work, it is often in such bad shape that it will not qualify for conventional long-term financing. This necessitates securing short-term capital for the acquisition and renovation.
Cash/Private Money: You can use your own cash or partner with other investors who provide the money while you provide the work and manage the deal. Private money is often the cheapest option (6-10% interest, no points).
Hard Money Loans (HMLs): These are short-term loans (typically 6-12 months) used for acquisition and rehab.
Important Reality Check: HMLs are expensive—more expensive than most beginners realize.
Interest rates: 10-15% annually
Points charged upfront: 2-5 points (a "point" is 1% of the loan amount)
On a $100,000 loan at 12% with 3 points, you'll pay $3,000 upfront plus $1,000/month in interest
Over 6 months, that's $3,000 + $6,000 = $9,000 in financing costs
Always include these costs in your holding cost calculations, or they'll destroy your returns.
HELOCs (Home Equity Lines of Credit): If you already own a primary residence with equity, a HELOC can be a low-cost, short-term funding source for acquisition or rehab (typically 4-8% interest, no points). The investor intends to pay it back (or most of it) during the refinance phase.
Partnerships: Team up with a capital partner who funds the deal (100% of purchase and rehab) in exchange for 50% of the equity and cash flow. You bring the work, they bring the money.
The goal of utilizing this short-term financing is not to rely on it long-term, but to secure the property and cover costs until the property is stabilized (fixed and rented), allowing the investor to pay back the initial lenders with the proceeds of the long-term refinance.
Don't close on a property until you can check every box:
☑ ARV verified with 3-5 recent, legitimate comps (within 6 months, within 1 mile)
☑ Contractor walked the property and provided written, itemized bid
☑ Property manager reviewed the property and confirmed rent estimates
☑ Holding costs calculated for 6-9 months (not best-case 3 months)
☑ 15-20% contingency added to rehab budget (non-negotiable)
☑ Refinance lender contacted and pre-qualified (you know their LTV, seasoning, and DSCR requirements)
☑ DSCR calculation confirms rent covers required debt service (typically 1.0-1.25x mortgage payment)
☑ MAO calculated conservatively (underwrite low, not optimistic)
☑ Exit strategy identified if refinance fails (can you sell? rent and hold long-term?)
By properly underwriting a deal using this conservative, systematic approach, you are much more likely to be successful in making the overall BRRRR strategy work.
This completes the first step: Buy. In the next installment, we will dive into the second crucial step of the acronym: R for Rehab, focusing on effective renovation strategies, managing contractors, and controlling costs to protect your margins.
