5 Contractor Mistakes That Can Wreck Your Tampa Fix and Flip Timeline

I’ve funded over $20 million in fix and flip loans in Tampa. Before that, I flipped houses myself starting in 2013. I’ve seen every possible way a contractor can destroy your timeline and your profit margin.

Today I’m sharing the five contractor mistakes that KILL more Tampa fix and flip projects than anything else. These aren’t theoretical problems. These are the exact issues I see borrowers face every single week.

Mistake #1: Hiring Based on Price Alone (The $30,000 Mistake)

Last month, an investor came to me in tears. They hired a contractor who bid $30,000 less than everyone else. Six weeks later, that contractor disappeared with a $15,000 deposit, leaving the house gutted and uninhabitable.

The cheapest bid is almost always the most expensive mistake you’ll make. Here’s why that low-ball contractor destroys your timeline:

First, they’re probably unlicensed. In Florida, unlicensed contracting is a criminal offense. First violation? Misdemeanor with up to a year in jail. But here’s what matters to you: when code enforcement discovers unlicensed work on your property, you get a stop work order. Your project sits dead while you pay daily carrying costs on your loan. I’ve seen investors rack up $10,000 in fines from unpermitted work by unlicensed contractors.

Second, they have no established subcontractor relationships. When they need an electrician, they’re calling around getting quotes. Your project sits for two weeks waiting. Meanwhile, the professional contractor has their electrician on speed dial because they’ve worked together for years.

Third, they have zero leverage with suppliers. During the supply chain issues of 2020-2024, I watched established contractors get materials while the cheap guys waited 12 weeks for basic items. Why? Relationships. The contractor who’s been buying from the same supplier for 20 years gets priority.

The Fix: Check every contractor’s license on MyFloridaLicense.com before you even discuss price. Call their insurance company to verify coverage. Talk to three recent flip investors who used them. Yes, you’ll pay 10-15% more for a licensed, insured professional. But you’ll actually finish your project.

Mistake #2: Starting Without Permits in Hillsborough County

I funded a flip in South Tampa where the contractor convinced the investor to “start demo while the permits process.” Three weeks in, code enforcement showed up. The result? Stop work order. $5,000 in fines. Plus a penalty equal to 100% of the original permit fees. The project sat dead for eight weeks.

Here’s what investors don’t understand about Hillsborough County permits: they’re not optional, and the penalties are severe. 😱

Everything goes through HillsGovHub online, and they don’t publish timeline estimates. Could be two weeks. Could be eight. But starting without permits isn’t the solution. It’s financial suicide.

The fines start at $500 per day. But that’s not the worst part. Unpermitted work creates a cloud on your title. You literally cannot sell the property until it’s resolved. I’ve seen closings fall apart because the buyer’s lender discovered unpermitted work during the appraisal.

The Fix: Your contractor should pull permits BEFORE touching the property. If they suggest starting without permits or say they’ll “handle it later,” fire them immediately. Budget 2-6 weeks for permit approval in your timeline. Yes, it’s painful to wait. But it’s less painful than a stop work order.

Mistake #3: Accepting a Vague Scope of Work

An investor came to me with a “great deal.” Their scope of work? One page that said “renovate kitchen and bathrooms.” That’s not a scope of work. That’s a blank check to your contractor.

Here’s what happens with vague scopes: everything becomes a change order. You said “new kitchen cabinets” but didn’t specify which ones. Contractor installs builder-grade. You wanted mid-grade. That’s a $5,000 change order. You said “new flooring” but didn’t specify luxury vinyl versus laminate. Another $3,000 change order.

I learned this lesson myself in 2014. Contractor quoted $15,000 for a kitchen remodel. By the time we finished all the “clarifications,” it cost $24,000. That $9,000 difference? That was supposed to be my profit.

The vague scope also makes scheduling impossible. How can your contractor schedule the tile installer when you haven’t chosen tile yet? How can they order cabinets when you haven’t picked a style? Your project stalls while you make decisions that should have been made before you started.

The Fix: Your scope of work should include every SKU number, every model number, every finish selection. It should be 10+ pages minimum. Yes, it takes time upfront. But it saves you from $20,000 in change orders and two months of delays. If your contractor accepts a vague scope without asking questions, they’re planning to profit from change orders.

Mistake #4: Paying Without Lien Waivers

This mistake has caused more investors to lose their properties than any other. You pay your general contractor in full. They don’t pay their subcontractors. Those subs file liens on your property. Now you have to pay twice or lose the house.

Florida’s Construction Lien Law is brutal. A subcontractor or supplier can file a lien even if you paid the general contractor in full. The law doesn’t care that you already paid once. If the subs didn’t get their money, that’s your problem.

I’ve seen a $200,000 flip get hit with $45,000 in liens after the contractor disappeared. The investor had to pay every subcontractor again just to clear the title and sell the property. Their profit? Gone. Actually, they lost $15,000.

Here’s the part that kills timelines: you can’t sell a property with liens on it. Your buyer’s lender won’t fund. So your finished flip sits on the market while you negotiate with angry subcontractors. Every day costs you money in carrying costs.

The Fix: Never release a payment without signed lien waivers. Before paying your contractor, get a list of all subs and suppliers on the job. Get lien waivers from everyone before releasing payment. Keep 10% retainage until the very end when you have final lien waivers from everyone. Yes, it’s paperwork. But it’s the paperwork that saves your investment.

Mistake #5: Ignoring Tampa’s Climate Requirements

Your out-of-state contractor might be excellent in Ohio. But if they don’t understand Tampa’s building codes, they’ll destroy your timeline and budget.

Most of Tampa falls within a Wind-Borne Debris Region (WBDR). Know what that means? Every window and door needs impact-resistant glass or approved shutters. Not a suggestion. CODE.

I reviewed a budget last week where the investor allocated $300 per window. Impact windows cost $800-1,200 each. On a house with 15 windows, that’s a $7,500-13,500 mistake. The contractor didn’t know. The investor didn’t know. They discovered it during the permit review. Project delayed six weeks while they scrambled for additional funding.

Then there’s flood zones. If your property is in a Special Flood Hazard Area and your renovation exceeds 50% of the structure’s value, you trigger substantial improvement requirements. You might need to elevate the entire structure. That $50,000 flip just became a $150,000 nightmare.

The humidity here destroys materials that work fine elsewhere. I’ve seen contractors use standard drywall in bathrooms. Three months later, mold everywhere. Project has to be redone. There goes your timeline and your profit. 💯

The Fix: Only hire contractors with extensive Tampa experience. During your interview, ask specific questions: What’s required in a WBDR zone? What materials do you use for high-humidity areas? How do you handle flood zone requirements? If they can’t answer immediately and specifically, they’re not qualified to work here.

Tampa Fix and Flip: Your Success Depends on Your Contractor

After 12 years in Tampa real estate, first as a flipper and now as a lender, I’ve seen it all. The contractor who took the deposit and flew to Costa Rica. The “professional” who didn’t know about impact window requirements. The unlicensed handyman who caused $30,000 in code violations.

Every one of these mistakes is preventable. But prevention requires you to be ruthless in your contractor selection and management.

Here’s my advice after funding hundreds of flips:

Interview five contractors minimum. Check every license. Call every reference. The Tampa REIA’s Onsite Renovation Group can give you the inside scoop on who to avoid.

Get everything in writing. Every selection, every timeline, every payment term. Your contract should be 20+ pages. If that seems excessive, you haven’t been burned yet.

Budget for reality, not hope. Add 15-20% contingency. Add 2-6 weeks for permits. Add 10-20% to material costs for Tampa’s climate requirements.

At SEP Capital, I don’t just lend money. I’ve been in your shoes. When you come to me with a deal, I’ll tell you if your contractor budget is fantasy. I’ll point out the red flags before they become disasters. Because when you lose money, eventually I lose money too.

The difference between a profitable flip and a nightmare is usually the contractor you choose and how you manage them. Choose wisely. Manage actively. And work with a lender who understands the game.
