Mistake #1 – Underestimating Total Project Costs

Why Underestimating Costs Matters

One of the biggest and most expensive errors homeowners make is failing to factor in all project expenses—like land preparation, permits, and those must-have appliances. By focusing solely on basic construction costs, you risk running out of funds when unexpected fees pop up.

How to Dodge It

  1. Work with your contractor to create a detailed, itemized budget.

  2. Include a 10–15% contingency fund for surprises.

  3. Research local material and labor rates to get accurate estimates from the start.

(Pro Tip: If you have equity in your land or existing property, discuss how that might offset some out-of-pocket costs with your lender.)

Mistake #2 – Choosing the Wrong Loan Type

Why The Wrong Loan Type Matters

Not all construction loans are built the same. Whether it’s a construction-to-permanent loan or a stand-alone construction loan, picking the wrong fit for your financial situation can lead to higher interest payments, tight terms, or balloon payments that sneak up on you.

How to Dodge It

  1. Define your long-term financial goals (e.g., will you refinance or sell soon?).

  2. Compare loan options carefully with an experienced construction lender.

  3. Consult a mortgage banker who understands new-build financing to ensure you get the loan type that best meets your objectives. Most bankers have never closed one of these loans, and you need to steer clear of this; you don’t want to be the guinea pig experiment in this process.

(BuildBuyRefi Home Loans can guide you through this maze, ensuring you know exactly what to expect.)

Mistake #3 – Neglecting to Secure Pre-Approval

Why Not Getting Pre-Qualified First Matters

Jumping headfirst into land or construction contracts without lender pre-approval can lead to financial (and emotional) turbulence. You risk losing deposits, stalling your project, and missing out on prime opportunities.

How to Dodge It

  1. Get your financial documents in order—tax returns, pay stubs, etc.

  2. Shop around for pre-approval with multiple lenders to compare offers.

  3. Remember, pre-approval isn’t final approval—you’ll still need to meet certain conditions later. You can start with our team quickly with a soft credit pull, so you don’t have to ding your credit report with inquiries while gathering details from all areas.

(Insider Tip: Having a pre-approval from a 50-state lender like BuildBuyRefi can strengthen your negotiating power when purchasing land or materials.)

Mistake #4 – Failing to Vet Contractors Thoroughly

Why The Wrong Builder or Contractor Matters

Your contractor is pivotal to bringing your vision to life. A less-than-stellar builder can blow your budget, botch craftsmanship, and disappear when problems arise.

How to Dodge It

  1. Check that your contractor has all required licenses and adequate insurance.

  2. Contact past clients to hear about their experiences.

  3. Ensure your contractor knows how to handle construction loan projects—there are extra steps and timelines to consider.

(Pro Tip: A reputable contractor should be able to provide references and a clear construction schedule—no exceptions.)

Mistake #5 – Ignoring the Draw Schedule

Why The Draw Schedule Matters

Construction loans usually pay out in “draws,” or lump sums, at key stages of your build. Misunderstandings around this schedule can create cash flow crunches, delay subcontractor payments, and even result in liens on your property.

How to Dodge It

  1. Review the draw schedule with your lender and contractor before work begins.

  2. Keep meticulous records of expenses, receipts, and subcontractor invoices.

  3. Proactively communicate with your lender—report progress updates to ensure the next draw is released on time.

Mistake #6 – Overlooking Loan Terms and Conditions

Why Construction Terms Matter

That fine print can hide some hefty surprises—like interest-only payments during construction or a balloon payment looming at the end. Even worse, we’ve seen brokers sharing astronomical administrative fees and points, meaning your house may not even appraise to start the loan, which could waste time. If you’re unprepared, these conditions can catch you off guard and strain your finances.

How to Dodge It

  1. Read every page of your loan agreement—even the boring bits.

  2. Ask your lender to explain any ambiguous language.

  3. Consider having an attorney glance over the details for extra peace of mind.

Mistake #7 – Changing Plans Mid-Construction

Why This Matters

Yes, sometimes changes are inevitable (looking at you, supply chain issues). But major plan shifts—like altering floor plans or upgrading to top-of-the-line finishes—can inflate your budget and delay the build.

How to Dodge It

  1. Finalize your building plans and specs before the first shovel hits the dirt.

  2. Discuss the financial implications with your lender and contractor if changes arise.

  3. Keep a flexible mindset, but be prepared to scale back if costs get out of hand.
