If you’re serious about building wealth through real estate investing, the BRRRR strategy is one of the most powerful approaches I’ve found. BRRRR — Buy, Rehab, Rent, Refinance, Repeat — is how I’m building a rental portfolio in Illinois while running a construction business, and it’s the strategy I recommend to anyone who wants to create real, lasting passive income.
I’m Tim Wangler. I’m a licensed General Contractor, Roofer, and Real Estate Agent in Illinois. I own Redeveloped Properties, a construction and investment company based in DuPage County. I don’t just talk about real estate investing — I do it every day. And I have an unfair advantage that most investors don’t: I can do the rehab work myself.
What Is the BRRRR Strategy and Why Does It Work?
For anyone new to real estate investing, here’s the BRRRR breakdown:
- Buy — Find a distressed or undervalued property below market value
- Rehab — Renovate it to force appreciation (increase its value through improvements)
- Rent — Place a quality tenant and generate cash flow
- Refinance — Get a new loan based on the improved value, pulling out most or all of your initial investment
- Repeat — Take that capital and do it again
The magic of BRRRR is that when you execute it correctly, you get your money back out of the deal AND you still own a cash-flowing rental property. You’re essentially building a portfolio with recycled capital. Each property pays for the next one.
My Unfair Advantage: Being a Contractor AND an Investor
Here’s where my situation is different from most real estate investors, and it’s something I want to be transparent about because it directly affects the numbers.
Most investors have to hire contractors for their rehabs. That means:
- Paying retail pricing for labor and materials
- Dealing with contractor delays and no-shows
- Losing money on holding costs while the rehab drags on
- Getting surprised by change orders and cost overruns
I don’t have any of those problems. I AM the contractor. My crew does the work. I buy materials at cost. I control the timeline. When I estimate a rehab at $40,000, it comes in at $40,000. When I say it’ll take 6 weeks, it takes 6 weeks.
That doesn’t mean you can’t do BRRRR without being a contractor. You absolutely can. But it means you need to build a GREAT relationship with a reliable contractor, and you need to have your numbers dialed in tighter because your rehab costs will be higher.
Finding BRRRR Deals in the Illinois Suburbs
The biggest challenge in the BRRRR strategy isn’t the rehab or the refinance — it’s finding the right deal. Here’s how I source properties in DuPage County and the surrounding areas:
MLS Deals
Yes, you can still find BRRRR deals on the MLS. Look for homes that have been sitting for 60+ days, price reductions, estate sales, and properties with terrible photos (often a sign of deferred maintenance = opportunity). Being a licensed agent gives me direct MLS access, which saves time and commissions.
Off-Market and Distressed Properties
Foreclosures, pre-foreclosures, probate properties, and code violation lists are goldmines. These sellers are motivated and the properties are usually priced below market. I use county records, driving for dollars, and networking with other investors and agents to find these deals.
Networking
Some of my best deals have come from other investors who got in over their heads, wholesalers who bring me properties, and even clients from my construction business who decide to sell their investment properties.
Running the Numbers: A Real BRRRR Example
Let me walk you through what a realistic BRRRR deal looks like in the western Chicago suburbs in 2026:
- Purchase price: $180,000 (distressed single-family home)
- Rehab budget: $45,000 (new kitchen, bathrooms, flooring, paint, roof repair, mechanicals)
- All-in cost: $225,000 (plus ~$8,000 in closing costs and holding costs = $233,000)
- After-repair value (ARV): $310,000
- Refinance at 75% LTV: $232,500 loan — you get essentially ALL your capital back
- Monthly rent: $2,200
- Monthly mortgage (PITI): ~$1,650
- Monthly cash flow: ~$550 (before reserves and management)
- Net cash flow: ~$300-350/month after reserves
So you own a $310,000 asset, you’re cash-flowing $300+/month, and you have your original capital back to do it again. That’s the power of BRRRR.
The Mistakes I See New BRRRR Investors Make
I’ve been in the construction and real estate business long enough to see a lot of investors blow up. Here are the most common mistakes:
- Overestimating ARV. Be conservative. Use actual sold comps, not Zestimates. If you’re wrong on ARV, the entire deal falls apart at the refinance step.
- Underestimating rehab costs. Add 15-20% contingency to every rehab budget. Things always come up — especially in older Illinois homes with knob-and-tube wiring, cast iron plumbing, or foundation issues.
- Ignoring holding costs. Every month your property sits during rehab, you’re paying interest, insurance, taxes, and utilities. Speed matters. This is where having your own crew is a massive advantage.
- Skipping inspections. Always get a thorough inspection before buying. A $500 inspection can save you from a $30,000 foundation surprise.
- Not having an exit strategy. What if you can’t refinance? What if rates spike? Always have a backup plan — can you sell it for a profit? Can you carry the higher payment temporarily?
Building Wealth Through Rental Properties: The Long Game
Here’s what most people don’t understand about rental property investing: the cash flow is nice, but the real wealth comes from three things happening simultaneously:
- Appreciation: Your property values increase over time (especially in strong markets like the Chicago suburbs)
- Debt paydown: Your tenants are paying off your mortgage for you, building your equity every single month
- Tax benefits: Depreciation, expense deductions, and 1031 exchanges make real estate one of the most tax-advantaged investments available
My goal is 20+ doors within the next 2 years. Each property is a small engine generating income, building equity, and appreciating in value. Stack enough of those engines together and you hit financial freedom — the point where your rental income covers all your expenses and you work because you want to, not because you have to.

Frequently Asked Questions About BRRRR Investing in Illinois
How much money do I need to start BRRRR investing?
It depends on your market and financing. In the Illinois suburbs, you can get started with $50,000-$75,000 in capital for your first deal using hard money or private lending for the purchase and rehab. Some investors start with less using creative financing, partnerships, or house hacking their first property.
Is the BRRRR strategy still viable in 2026 with higher interest rates?
Yes, but you have to be more selective. Higher rates mean your cash flow margins are thinner, so you need to buy at bigger discounts and be more disciplined on rehab budgets. The strategy still works — you just can’t be sloppy with your numbers.
Should I use an LLC for my rental properties?
I strongly recommend it for liability protection. Most of my investment properties are held in LLCs. Talk to a real estate attorney and CPA before structuring — the right setup depends on your situation, number of properties, and state laws.
Can I do BRRRR while working a full-time job?
Absolutely. Most investors I know started while working full-time. The key is systems — find a good contractor (or partner with one), hire a property manager once you have a few units, and build a team around you. You don’t have to do everything yourself.
