How To Flip Houses: A Practical Beginner Guide

Many new investors want to learn how to flip houses to gain more control over their time, income, and future. But flipping houses is not just about buying a cheap property and selling it for more. It takes lead generation, deal math, local market knowledge, and the discipline to walk away when the numbers do not work.

We reviewed Chris Mignone’s DealMachine story, the basics of real estate investing, and current compliance concerns regarding wholesaling to build a practical guide for new investors. Chris started as a union glazier in New York City and began learning real estate during 2020. His journey included a $35,000 win from a duplex deal and a $25,000 loss on a flip, which makes his story useful for investors who want the upside without ignoring the risk.

That mix matters. Real estate can create opportunity, but a bad deal can drain your money fast. If you want to flip houses, start by learning how to find deals, check the numbers, and choose the right exit before you buy.

What It Means To Flip Houses

To flip houses, you buy a property, improve it, and sell it for more than your total cost. Your total cost includes the purchase price, repairs, closing costs, loan costs, utilities, insurance, taxes, and selling costs.

The goal is not to make the house perfect. The goal is to make smart repairs that help the property sell for a price that leaves room for profit. That means every decision should connect back to the numbers.

Chris learned this lesson through real experience. After earning a strong assignment fee on one deal, he also faced a major loss on a flip. That is why new investors should treat house flipping like a business, not a gamble.

Flipping Vs. Wholesaling Vs. Wholetailing

These three strategies are connected, but they work in different ways.

House flipping means buying a property, repairing it, and reselling it.

Wholesaling means you get a property under contract and assign your contract rights to another buyer for a fee.

Wholetailing means you buy the property, make light updates or clean it out, then resell it without doing a full renovation.

Chris’s $35,000 duplex deal was wholesale-style. He found an off-market property, got it under contract, and assigned the contract to another investor. That kind of deal can help a beginner build cash before taking on the larger risk of a full flip.

How To Find Houses To Flip

Most good flips start before the property is listed online. If a house already has many buyers competing for it, your room for profit may shrink fast.

That is why many investors look for off-market properties. These may include vacant homes, tired rentals, inherited properties, or houses with visible signs of deferred maintenance.

DealMachine helps investors find and analyze off-market properties through driving-for-dollars tools, property data, lead management, and marketing automation. It is built to help investors find leads, organize outreach, and follow up with owners more consistently.

Build A Clear Buy Box

A buy box is a simple set of rules for the kind of property you want. It keeps you from chasing every possible lead.

Your buy box may include:

• Property type
• Neighborhood
• Price range
• Repair level
• Exit strategy
• Owner type
• Minimum profit target

For example, a beginner may focus on single-family homes in working-class neighborhoods that need cosmetic updates but not major structural repairs. Another investor may focus on small multi-family properties with tired landlords.

Chris focused on non-owner-occupied properties and small multi-family opportunities. That helped him narrow his search and spend more time on leads that fit his goals.

Use Driving For Dollars To Spot Leads

Driving for dollars means you drive or walk neighborhoods and look for properties that may need attention. You may see tall grass, boarded windows, mail buildup, old roofing, peeling paint, or code notices.

These signs do not prove an owner wants to sell. They simply help you build a focused list of properties worth researching.

Once you find a property, check the owner details, mailing address, and property history. Then start a simple follow-up process. Many deals do not happen from the first call or first postcard. They happen because you kept good records and followed up at the right time.

How To Run The Numbers On A Flip

A flip is won or lost before you buy. If you pay too much, the project may fail even if the renovation looks great.

Start with the after-repair value, also called ARV. This is the likely resale value after repairs are complete. You estimate ARV by looking at nearby properties that have sold and are similar in size, style, condition, and location.

Do not use active listings as proof of value. A seller can ask any price. Sold properties show what buyers have actually paid.

Use The Maximum Allowable Offer Formula

A common investor formula is the Maximum Allowable Offer, or MAO. It helps you estimate the highest price you can pay while leaving room for repair costs, risk, and profit.

Here is a simple version:

MAO = (ARV x 0.70) - Estimated Repair Costs - Wholesale Fee

If you are flipping instead of wholesaling, you can replace the wholesale fee with your target profit or assignment spread.

For example:

In this example, the investor would not want to offer more than $110,000 unless there is a clear reason the numbers are better than expected.

This formula is not perfect. Some markets, loan terms, and repair scopes require different margins. But it gives beginners a simple way to avoid overpaying.

Add A Repair Cushion

Repair costs are one of the easiest places to make a costly mistake. A property may look simple during the first walk-through but later reveal plumbing, electrical, roofing, or foundation issues.

Ask a contractor to walk the property with you when possible. Get written estimates. Then add a cushion for surprises.

Common repair categories include:

• Roof
• HVAC
• Plumbing
• Electrical
• Foundation
• Windows
• Kitchen
• Bathrooms
• Flooring
• Paint
• Landscaping
• Cleanout

A beginner-friendly flip usually has fewer unknowns. Cosmetic updates are easier to plan than major structural work.

Chris’s Deal Lessons: Win Vs. Loss

Chris’s story works because it shows both sides of investing. He had a major win, but he also took a painful loss. That is closer to real life than only showing success stories.

Here is a simple breakdown of the lessons from both deals:

The takeaway is simple. Do not judge your business by one deal. Track what worked, what failed, and what needs to change before the next offer.

How To Reduce Risk Before You Buy

Risk is part of flipping houses, but you can control more than you may think. The first step is to slow down before you sign.

A seller may want a fast answer. A contractor may give you a rough number. A lender may approve your funding. None of that means the deal is safe.

Use a checklist before making an offer:

1. Confirm ownership.
2. Review nearby sold properties.
3. Estimate ARV.
4. Walk the property.
5. Get repair input.
6. Review title issues.
7. Estimate holding costs.
8. Confirm your exit strategy.
9. Check local rules.
10. Make the offer based on math.

If one of these items is missing, your risk goes up.

Know The Rules Before Wholesaling

Many investors learn how to flip houses by starting with wholesaling. That can be a useful path, but wholesaling rules vary by state.

In Texas, the Texas Real Estate Commission explains that a person assigning an interest in a contract must accurately disclose the nature of the interest being offered. TREC also says that offering a property for sale when you do not own it can be brokerage activity that requires a license.

Oklahoma has also added specific wholesale contract rules. The Oklahoma Real Estate Commission’s wholesale contract materials include required written disclosures and cancellation rights for homeowners.

Illinois regulates real estate activity under the Real Estate License Act of 2000, and investors should review current state rules before wholesaling there.

This is not legal advice. Before you wholesale, assign contracts, advertise deals, or market property interests, talk with a local real estate attorney or broker who understands your state’s rules.

How DealMachine Fits Into A House Flipping Workflow

DealMachine is not a replacement for deal analysis, legal review, or contractor input. It is a tool that can help you build the front end of your investing business.

That front end matters because you need leads before you can make offers. Without leads, you are stuck waiting for public listings that many other buyers may already be looking at.

DealMachine supports investors by helping them:

• Find off-market properties
• Track driving-for-dollars leads
• Access useful property data
• Organize seller outreach
• Manage follow-up
• Support marketing workflows

The strongest investors do not rely on memory. They use systems to track properties, owners, conversations, and next steps.

A Beginner Plan For Your First Flip

Your first flip should be simple. Avoid the project that needs everything fixed unless you have the team and cash to handle it.

Start with one market and one property type. Learn the neighborhoods, price ranges, buyer demand, and repair costs. Then build a lead list and practice running numbers every week.

Here is a practical starting plan:

1. Pick one target area
2. Choose your property type
3. Build a driving-for-dollars list
4. Research owner details
5. Start seller outreach
6. Follow up with every lead
7. Estimate ARV using sold comps
8. Walk properties with repair costs in mind
9. Use the MAO formula before offering
10. Choose your exit before closing

The goal is not to make a fast offer. The goal is to make a smart offer.

Common House Flipping Mistakes To Avoid

The biggest mistake is paying too much. A high purchase price can ruin a deal before repairs even start.

Another mistake is underestimating the timeline. Every extra month can add costs for taxes, insurance, utilities, loan interest, and maintenance.

New investors should also avoid copying another investor’s deal without understanding the numbers. A deal that works for a contractor with cash may not work for a beginner using expensive funding.

Watch out for these mistakes:

• Using asking prices instead of sold comps
• Forgetting closing and selling costs
• Skipping contractor estimates
• Ignoring permits
• Taking on too much rehab
• Assuming every distressed house is a deal
• Marketing a wholesale deal without knowing local rules
• Buying without a backup exit

A good deal should still make sense if repairs take longer or the resale price comes in lower than expected.
