BRRRR is a popular real estate investing strategy. The letters stand for Buy, Rehab, Rent, Refinance, Repeat.
The idea is simple: buy a property that needs work, improve it, rent it out, refinance based on its new value to pull out some of your cash and use that cash for the next property.
When it works, it can help investors grow a portfolio without bringing all new cash to every deal. But it depends on several things going right at once: the purchase price, the rehab budget, the rent, the appraisal and the refinance. If one of them doesn't work out, your cash can stay tied up in the property.
In this post, I'll explain each step, the capital you'll need, the refinance and valuation risks, rent-up, reserves and what to do if the plan doesn't go as expected.
This is general education, not investment, tax or legal advice, and it's not a loan offer. Loan programs and eligibility depend on lender review and approval.
The Five Steps
1. Buy
You purchase a property below what it could be worth after improvements, usually because it needs work. The price you pay sets up everything else.
2. Rehab
You renovate the property to make it rentable and, ideally, more valuable. My post on evaluating a fixer-upper renovation budget covers scope, bids, permits, contingency and holding costs.
3. Rent
You place a qualified tenant at a market rent, following fair housing and tenant protection rules.
4. Refinance
You apply for a new loan based on the property's current value after the rehab. If the new loan is large enough, it may pay off your original financing and return some of your cash.
5. Repeat
You use the returned cash toward the next property.
Capital Needs: What You'll Need Up Front
BRRRR usually requires significant cash or financing at the start.
Typical cash needs:
- Purchase: down payment, or the full price if buying with cash.
- Closing costs on the purchase.
- Rehab costs, including permits and contingency.
- Holding costs during the rehab: loan payments, taxes, insurance, utilities.
- Lease-up costs: marketing, cleaning and vacancy until the first tenant moves in.
- Refinance closing costs.
- Reserves for the unexpected.
Financing during the buy and rehab phases can take different forms, depending on the investor and the property. Each type has its own costs, terms and risks. I don't quote rates or terms here because they change and depend on each borrower and lender.
Refinance Risk: The Most Important Part
The refinance step is where many BRRRR plans succeed or fail.
What has to go right:
- The appraisal. The new loan amount depends on the appraised value. If the appraisal comes in lower than you expected, the loan may be smaller, and less of your cash comes back.
- Lender requirements. Lenders have rules for cash-out refinances, which may include how long you've owned the property, how value is supported and how rental income is counted. Fannie Mae's Selling Guide, for example, has a section on cash-out refinance transactions. Each lender and program is different.
- Your qualifications. Credit, income, reserves and the number of properties you already finance all matter. My post on financing multiple investment properties explains some of the factors.
- Market conditions. If rates rise or lending standards tighten while you're rehabbing, the refinance may look different from your original plan.
If the refinance doesn't work as planned, you may still have a rented property, but with more of your cash tied up in it than you intended.
Talk With a Lender Before You Buy, Not After
Many investors wait until the rehab is finished to talk about the refinance. By then, the key decisions have already been made. A short conversation with a lender before you buy can tell you:
- Which documents you'll need for the refinance.
- How the lender may look at the property's value and rental income.
- Whether there are timing rules that affect your plan.
- How your other financed properties may affect eligibility.
The answers can change your offer price, your rehab scope or whether the property is a fit at all.
Valuation Risk
Your plan depends on what the property is worth after the rehab, often called after-repair value (ARV).
- Base ARV on truly comparable sales, not the best sale in the area.
- Remember that appraisers make their own judgment, using their own comparable sales.
- Over-improving for the neighborhood may not raise the appraised value as much as it costs.
- Market changes during a long rehab can change values.
Test lower values. What happens to your plan if the appraisal comes in below your ARV estimate?
Rent-Up Risk
The "Rent" step also has risks.
- Time to find a tenant. Vacancy during lease-up adds holding costs. My post on how vacancy rates affect cash flow explains how to plan for it.
- Achievable rent. Base rent on current comparable rentals, not on hopes.
- Rules. State and local rent and tenant protection rules apply. The California Attorney General explains statewide rules. Some cities, like San José, have their own programs.
- Lender treatment of rent. How a lender counts rental income for the refinance depends on the program and documentation.
Cash Flow After the Refinance
Even if the refinance returns your cash, the new loan payment may be higher than the original. Before you start, ask:
Will the property still cash flow after the refinance?
| Line | After refinance (monthly) |
|---|---|
| Rent | $ |
| minus: Vacancy allowance | $ |
| minus: Operating expenses (taxes, insurance, repairs, management, reserves) | $ |
| minus: New loan payment | $ |
| Cash flow after refinance | $ |
If the answer is negative, think carefully about whether the strategy fits your goals and reserves.
Reserves: Your Safety Net
BRRRR involves more moving parts than buying a ready-to-rent property. Reserves help you survive delays and surprises.
Plan reserves for:
- Rehab overruns beyond your contingency.
- Longer holding periods if permits or contractors are delayed.
- Lease-up delays.
- Lower-than-expected refinance proceeds.
- Repairs after tenants move in.
My post on budgeting for repairs and capital expenditures explains how to build a reserve plan.
Exit Alternatives if the Plan Changes
Good investors plan for the strategy not working perfectly.
- Hold with more cash in the deal. If the refinance returns less cash, you may keep the property as a rental and wait.
- Refinance later. If values or lending conditions improve, you might try again.
- Sell. If the numbers don't work as a rental, selling may recover some or all of your investment, minus selling costs. Talk with your CPA about taxes.
- Bring in a partner. Some investors share the investment, with legal agreements in place.
Knowing your alternatives before you buy helps you make calmer decisions later.
BRRRR in the Bay Area: Things to Consider
- High prices mean large amounts of capital are tied up in each deal.
- Permits and contractor schedules can make rehabs take longer than expected.
- Property taxes are generally reassessed at purchase in California. Estimate them based on your price. The State Board of Equalization's Publication 29 explains how.
- Insurance quotes should be gathered early, both for the rehab and the rental phase.
- Tenant rules can be stricter in some cities.
These factors don't rule out BRRRR, but they make careful analysis and strong reserves even more important.
A Simple BRRRR Worksheet
| Line | Amount |
|---|---|
| Purchase price | $ |
| plus: Purchase closing costs | $ |
| plus: Rehab, permits and contingency | $ |
| plus: Holding costs during rehab | $ |
| plus: Lease-up costs | $ |
| Total project cost | $ |
| Expected appraised value after rehab (ARV) | $ |
| Expected new loan amount (from lender) | $ |
| minus: Payoff of original financing | $ |
| minus: Refinance closing costs | $ |
| Cash returned at refinance | $ |
| Cash left in the deal (total cash invested − cash returned) | $ |
| Cash flow after refinance (yearly) | $ |
Fill this in with real bids, comparable sales, comparable rents and loan terms from your lender. Then test a lower ARV and higher rehab cost.
Questions to Ask Before You Start
- Is the purchase price low enough to leave room for rehab, holding costs and a margin?
- Do I have written rehab bids and a contingency?
- Is my ARV based on truly comparable sales?
- Have I talked with a lender about refinance requirements for my situation?
- Will the property cash flow after the refinance?
- What happens if the appraisal is lower than expected?
- How long can my reserves carry the property?
- What's my exit if the plan changes?
Common BRRRR Mistakes
- Overestimating ARV.
- Underestimating rehab costs and time.
- Not talking with a refinance lender early.
- Ignoring cash flow after the refinance.
- Thin reserves.
- Over-improving for the neighborhood.
- Assuming the strategy always returns all your cash.
Key Takeaways
- BRRRR = Buy, Rehab, Rent, Refinance, Repeat.
- It needs significant capital up front.
- The refinance and appraisal are the biggest risks.
- Check cash flow after the refinance.
- Plan reserves and exit alternatives before you start.
A Hypothetical Example
This example is made up to show the process. It is not based on any real property, client or loan.
An investor buys a dated single-family home, renovates the kitchen and bathrooms and replaces the electrical panel with permits. The rehab runs a month longer than planned, but the contingency covers the extra cost.
They place a tenant at a rent supported by comparable rentals. When they apply to refinance, the appraisal comes in a bit below their ARV estimate. The new loan returns part of their cash, but not all of it. Because they had planned for this scenario and kept reserves, they keep the property as a rental, with cash flow that still works, and decide to wait before starting the next project.
Frequently Asked Questions
What does BRRRR stand for?
Buy, Rehab, Rent, Refinance, Repeat.
Does BRRRR always return all my cash?
No. How much cash comes back depends on the appraisal, the lender's terms and your total costs.
When can I refinance after buying?
It depends on the lender and program. Some have rules about how long you've owned the property. Ask your lender before you buy.
What if the appraisal is low?
The new loan may be smaller, leaving more cash in the deal. Plan for this scenario.
Is BRRRR a good fit for the Bay Area?
It can be, but high prices, permit timelines and insurance costs make careful analysis and reserves important.
Do I need a property manager for BRRRR?
Not necessarily. Some investors self-manage. Include management costs in your analysis either way.
What are the biggest risks?
Rehab overruns, low appraisals, refinance changes, vacancy and thin reserves.
Should I talk to a CPA?
Yes, about taxes on rental income, depreciation and any future sale.
How I Can Help
As a broker and loan officer, I help investors evaluate BRRRR plans from the start: reviewing purchase price against realistic ARV, building rehab and holding cost estimates and talking through refinance considerations early. Loan options always depend on lender review and approval.
The Bottom Line
BRRRR can help investors grow, but it depends on buying at the right price, controlling the rehab, renting at market, appraising well and refinancing on workable terms. Test lower values and longer timelines, check cash flow after the refinance, keep strong reserves and know your exit options.
