Top mistakes new investors make?

Question

I'm looking to start my first flip soon.  What are some of the biggest mistakes you often see new investors make that cause them to fail out of real estate investing?  What actions can/should be taken to avoid these mistakes?  I'm looking to make REI my full time gig here within the next 3 years, so I want to make sure I'm not one and done after my first flip.

Buying in class D area's becasue it is "cheap". There are reasons it is cheap.

1. Underestimating rehab costs. Most new flippers are blissfully ignorant as to what certain jobs should cost

2. acquiring property at the lowest price possible. Newbie's tend to overpay and just want to get started when they really should wait for the right deal

3. lacking mentors. Asking questions on sites such as bigger pockets can fill in Knowledge gaps but won't provide you with a scalable system

1) Not walking the property before offering with at least one GC.

2) Not getting a line by line detailed scope of work from the GC.

3) Underestimating holding costs and timeframe of the rehab.

4) Looking at the wrong comps or not doing enough research on the block.

5) Shortcut the rehab and be faced with a incomplete rehab that has to be redone or finished.

Max Emory · Answer

@Nate Garvey, great question.

#1 Focusing on the wrong things at the wrong time. Think of a new REI who is super focused on entity structure and tax savings before doing their 1st deal.

#2 Lack consistency. Think not working on the right things they should every single day.

#3 Lack discipline. Think not abiding by their buy box criteria (once it's dialed in).

#4 Don't measure things. Think not having data to lean on to make better decisions over time. They continue to make the same mistakes and don't know why they're not winning.

Hope this helps!

Underestimating rehab costs, just picking any location, and doing due diligence.

Congrats on getting ready for your first flip! One of the biggest mistakes I see? Not keeping clean books from day 1!

Flippers often focus on demo and design—but loose numbers = lost profits.

🔹 Track every expense (materials, permits, mileage)
🔹 Use a simple system like QuickBooks early on
🔹 Review costs weekly—don’t wait until tax time

Know your numbers = protect your margins.
Success isn’t just built with hammers—it’s built with clarity. 💡

Completely agree with what everyone else has said thus far, underestimating rehab cost, overestimating ARV, buying in Class D areas, lack of a good contractor database...

I'd also like to add, over stylizing the house and/or personalizing it to their taste and choosing the wrong materials either because of costs or style preferences. Ultimately, choose materials and colors based on what will sell to more than 1 person.

Expecting other people to do your heavy lifting (metaphor)

your the bottom line, the buck stops with you.  Whether underwriting, doing due diligence, estimating, managing or a litany of other tasks, no matter what goes wrong it's on you.

Dont; invest & forget, trust but not verify, get apathetic or blame others it's still on you.

This is a merit based industry so s**t will happen, learn from your mistakes and figure out a way to make things happen.

There are no problems, there are only opportunities for solutions.

Hi @Nate Garvey

Here are a few things that investors make a mistake on

1. Underestimating Renovation Costs2. Overpaying for the Property3. Choosing the Wrong Location4. Bad Contractor Relationships5. Underestimating Holding & Selling Costs6. Not Having Multiple Exit Strategies7. Trying to Do Everything Yourself

Diego A. · Answer

These are the main issues that I have found:

1. Underestimating the work that it takes. Involvement is key.

2. Rush to get into the first deal.

3. Underestimating rehab costs (Overestimating ARV).

4. Time management. Underestimating the time that will take to complete the work, lack of project management experience.

5. Commitment to the project.
