10 Fix-and-Flip Mistakes That Kill Profits in California
Fixing and flipping homes in California can be very profitable for real estate investors, but fierce competition leaves no room for error; the numbers, execution, and timing must all be on point.
Various factors, such as high purchase prices, complicated permitting, expensive holding costs, and delayed timelines contribute to profits easily being destroyed by small mistakes.
Whether your fix-n-flip project is in Los Angeles, Santa Barbara, San Diego, Orange County, or San Francisco, avoid these 10 common fix-and-flip mistakes to ensure your project is a success.
1. Overly Optimistic After-Repair Values (ARV)
The purchase price and sale price are the two most critical factors when performing a fix-n-flip. If you overbid a deal with multiple offers or inflate the ARV to justify the project, you could pay for it in the end.
California investors often assume appreciation will save a marginal deal, but that is not reliable or strategic thinking.
Why It’s a Problem
Buying too high and or overestimating ARV reduces your profit margin, leaving you little margin for error in the event your project has delays or the real estate market takes a downturn.
-
Use recently sold comps in the area as benchmarks; be sure to adjust for size, condition, and location
2. Not Accounting for Margin of Error
Real estate construction projects are typically full of unwanted surprises, ranging from permitting, plumbing, electrical, or mold issues.
This is why experienced flippers in major markets like Los Angeles or San Diego don’t try to hit home runs on every deal; they aim for a margin of safety.
Why It’s a Problem
Deals with minimal meat on the bone can magnify each and every mistake. Going over budget, combined with a few weeks of delays and a price reduction, will all but eliminate any remaining profit.
-
Buy way below ARV
-
Use a spreadsheet to factor in financing costs, taxes, insurance, utilities, and broker's fees
-
You don’t have to swing at every deal that comes your way; walk away if the deal doesn’t work using conservative projections
3. Underestimating Rehab Costs
Over the past 5 years, the cost of construction labor and materials in California has drastically risen by 39% to 44%, and now sits among the highest in the nation.
Therefore, each additional issue you uncover, whether it be structural or unpermitted work, is going to increase your renovation costs and cause your bottom line to take a hit.
Why It’s a Problem
Unexpected repairs can decimate projected profit.
-
Do a detailed inspection before closing
-
Itemize each rehab cost prior to purchase
-
Partner with an experienced fix-n-flipper or contractor
-
Set aside 15 to 20% in contingency reserves
4. Going Overboard on Improvements in a Mid-market Neighborhood
Understand what is selling in the market and what renovations people will pay for, and don’t go above and beyond what is necessary.
For example, not every market in Los Angeles is like Beverly Hills and therefore doesn’t require the best-of-the-best finishes.
High-end finishes might increase resale value, but don’t always result in maximum profit.
Why It’s a Problem
Buyers won’t pay luxury prices in mid-market neighborhoods, regardless of how nice the upgrades are.
-
Renovate up to neighborhood standards, not personal taste; this is not your forever home
-
Tour nearby sold homes and open houses to see what other flippers are doing
-
Spend on the kitchen, bathrooms, and exterior curb appeal
5. Forgetting Holding Costs
Remember, time is money. Those words have never been truer than when it comes to fix-and-flip projects in California.
With each additional month your project runs, many small holding costs can add up to a considerable sum.
Why It’s a Problem
Holding costs such as loan interest, insurance, taxes, utilities, and opportunity costs to your business.
-
Budget holding costs upfront
-
Use financing that provides speed and flexibility
6. Using the Wrong Contractor with Poor Oversight
Contractors love to overpromise and underdeliver when it comes to fix-and-flip budgets and timelines.
Never assume the contractor will finish when they estimate. Prepare for delays and setbacks by adding an extra month or two to the overall timeline.
The wrong contractor can not only derail your project but also cause you stress and financial burdens.
Why It’s a Problem
Project delays and cost overruns, combined with poor workmanship and failed inspections, equal a major headache.
-
Use vetted contractors from other flippers
-
Get everything in writing
-
Link payments to completed milestones and have penalties if missed
-
Hire a project manager to watch over the contractor if you don’t have the time
-
Stay as involved as possible throughout the project
7. Trying DIY Skilled Construction Work
California strictly enforces contractor licensing.
For certain jobs, skilled labor is required, but foolishly, some investors try to save money by doing complex jobs themselves.
Why It’s a Problem
Mistakes can lead to poor work, inspection failures, legal risk, and red flags for buyers, ultimately lowering the value of your home.
-
Leave skilled work to the pros
-
Focus your time on new acquisition targets, oversight, and resale strategy
-
Quality work always sells faster and fetches more in the market
8. Underestimating Project Timelines
Fix-n-flip projects almost always take longer than expected. The typical California fix-n-flip takes between 3 and 6 months, depending on contractor scheduling, permit turnaround, and the amount of work the property needs.
Here is a breakdown of the typical phases:
- Property purchase & financing: 2 to 8 weeks
- Permits: 1 to 4 weeks
- Renovations: 8 to 16 weeks
- Selling: 4 to 12 weeks
Why It’s a Problem
Delays to any or numerous phases of the fix-n-flip process increase holding costs and expose you to dangerous market pricing fluctuations.
-
Prepare for delays with emergency funds
-
Add 30 to 60 days of buffer to your projections
-
Plan financing terms to fit this schedule
9. Selecting the Wrong Type of Financing
While the traditional 30-year mortgage provided by banks is the most popular mortgage in America, it is not ideal for fix-and-flip transactions.
Bank loans can take months to fund and require extensive paperwork; hard money is the fastest path to a fix-and-flip loan with minimal paperwork for real estate investors seeking agile financing.
Why It’s a Problem
- Not all funding is ideal for California fix-and-flip projects.
- Inflexible loan structure, slow draws, and the need to close quickly can cause deals to slip away.
-
Use short-term hard money financing designed specifically for flips
-
Understand the terms, including rates, fees, draw schedules, and payoff timelines
-
Agree to loan terms that conservatively coincide with the anticipated project duration
10. Overpricing at Resale in Slowing Secondary-Markets
Even in The Golden State, buyer demand can shift quickly.
Many flippers overprice at resale hoping to “test the market.”
By pricing the home competitively from day one it creates urgency amongst prospective buyers.
Why It’s a Problem
Homes that sit too long lose traction and cost more to carry.
-
Price based on recent comps, not sunk costs
-
Aim for a fast, clean exit
-
A slightly lower price often yields a higher net profit
