Prequalification vs. Preapproval: What Is the Difference?
These two terms come up at the start of every home purchase and they are not the same thing. Understanding which one you need, and when, helps you move faster when the right home comes up.
Prequalification
Estimate your borrowing range
What It Involves:
- Self-reported income and assets only
- No hard credit pull
- Takes minutes to complete
- General estimate, not a commitment
Best For: Budget planning before you start house hunting. Sellers will not accept this in place of a preapproval letter.
Preapproval
Conditional commitment from the lender
What It Involves:
- Hard credit pull required
- Income, assets, and employment verified
- Takes 1 to 3 business days
- Accepted by sellers as proof of ability to close
Best For: Making an offer on a home. In a competitive market like Cedar Rapids, most sellers expect one before accepting an offer.
FSB Recommendation:
Get prequalified first to understand your range, then move to preapproval before you make an offer. Your FSB lender will walk you through both steps and tell you exactly what to bring to each.
Credit Score Requirements by Loan Type
Your credit score determines which mortgage programs you qualify for and directly affects the interest rate you receive. Higher scores open more options and lower your long-term cost.
FICO scores range from 300 to 850. Mortgage lenders pull scores from all three credit bureaus and typically use the middle score. The thresholds below reflect common requirements, though your specific situation may vary.
How to Strengthen Your Credit Before Applying:
- Pay all bills on time for at least 6 months before applying
- Keep credit card balances below 30% of each card's limit
- Pull your credit reports from all three bureaus and dispute any errors
- Do not open new credit accounts before or during the application process
- Keep existing accounts open to preserve your length of credit history
Steps to Apply for a Mortgage with FSB
Whether you are buying your first home in Marion or refinancing in Tiffin, the process works the same way. Here is what happens at each stage.
The FSB Mortgage Process
1
Start Your Online Application
Use FSB's secure online application to enter your income, assets, and debts. This triggers the formal mortgage application and starts the prequalification process. The application takes 10 to 15 minutes. Have your Social Security number, employer details, and a rough estimate of your monthly debts ready before you begin.
2
Gather and Upload Your Documents
Your lender will need to verify what you entered in the application. Having pay stubs, W-2s, tax returns, and bank statements ready before your first lender call significantly speeds up the timeline. See the complete checklist below.
3
Connect With Your FSB Lender
An FSB mortgage lender will contact you within one business day to confirm your details and explain the next steps. FSB lenders are local, which means loan decisions are made in Eastern Iowa rather than routed through an out-of-state approval center. Prefer not to wait? Reach the mortgage team at 319-730-6990.
4
Compare Your Loan Options
Your lender will walk you through the programs that fit your situation, including fixed-rate, adjustable-rate, FHA, VA, and conventional options. They will compare monthly payments, total loan costs, and down payment requirements so you can choose with confidence. See FSB's mortgage loan options here.
5
Lock Your Rate and Close
Once you are approved and under contract for a home, you will lock in your interest rate. FSB coordinates directly with your realtor and title company. Your lender prepares you for closing so there are no surprises at the table. At closing, you sign your loan documents, pay any remaining closing costs, and get the keys.

Mistakes That Delay or Derail Mortgage Approval
Most mortgage delays come from the same handful of avoidable mistakes. Knowing them before you apply can save you weeks and prevent a denial at the worst possible moment.
✕ Opening New Credit Accounts
A new card or auto loan changes your debt-to-income ratio and triggers a hard inquiry. Both can affect your approval or rate. Do not open any new accounts between the application and the closing day.
✕ Large Undocumented Cash Deposits
Lenders must source all funds in your accounts. An unexplained large deposit triggers a request for a letter of explanation and can delay your closing date. Keep a paper trail for any large cash movements.
✕ Changing Jobs Mid-Process
Employment stability is a key underwriting factor. Switching employers, going from salaried to self-employed, or taking a pay cut during the process requires a full income re-verification. Notify your lender immediately if a job change is unavoidable.
✕ Major Purchases Before Closing
Furniture, appliances, and a vehicle before your loan closes increases your debt load and can push your debt-to-income ratio above the threshold. Hold off on major purchases until after the keys are in your hand.
✕ Skipping Preapproval
Sellers in Cedar Rapids and Marion frequently require a preapproval letter before accepting an offer. Skipping it puts you at a disadvantage and wastes time looking at homes outside your actual range.
✕ Co-Signing on Another Loan
Co-signing adds that debt to your profile even if you are not making the payments. This affects your debt-to-income ratio and can affect your approval amount or qualification entirely.
🚩 Timeline Warning:
These mistakes are most damaging in the 60 to 90 days before you apply and between application and closing. Lenders may re-pull your credit just before closing. A change in your credit profile at that stage can delay or terminate your loan.

Frequently Asked Questions
What is the first step to applying for a mortgage?
Start by reviewing your finances and checking your credit score, then get prequalified with a lender. Prequalification estimates how much you can borrow based on self-reported income and assets, without a hard credit pull. From there, gather your documents and move to preapproval before making an offer on a home.
What are the three main requirements to get a mortgage?
The three primary requirements are proof of income to show you can repay the loan, acceptable credit history that meets the loan program's minimum score, and down payment or equity funds. Conventional loans can start as low as 3 percent down; FHA loans require 3.5 percent with qualifying credit.
What credit score do you need to buy a house in Iowa?
Requirements vary by loan type. FHA loans allow scores as low as 580 with 3.5 percent down. Conventional loans typically require 620 or higher. The higher your score, the better your rate options. Contact an FSB lender for guidance on your specific situation before you start house hunting.
What are the six items that trigger a formal loan application?
Under federal guidelines, a loan application is triggered when a lender receives your name, income, Social Security number, the property address, an estimated property value, and the loan amount requested. Once all six are collected, lenders must provide a Loan Estimate within three business days.
What is the 28/36 rule for mortgages?
The 28/36 rule says your monthly housing costs, including principal, interest, taxes, and insurance, should not exceed 28 percent of your gross monthly income. Your total monthly debt payments including housing should not exceed 36 percent. Staying within these limits makes approval more straightforward and reduces financial strain over the life of the loan.
How long does it take to get a mortgage approved in Iowa?
Expect three to six weeks from application to closing. Having all documents ready before you apply and responding quickly to lender requests keeps things on track. FSB makes decisions locally, which removes the delays that come with out-of-state underwriting queues.
Can I get preapproved for a mortgage before I find a house?
Yes, and FSB recommends it. Getting preapproved before you shop tells you exactly how much you can borrow, strengthens your offer, and speeds up closing. Sellers in Cedar Rapids and Marion often prefer buyers who already have a preapproval letter in hand.
What should you not do before applying for a mortgage?
Do not open new credit accounts, make large cash deposits you cannot document, make major purchases before closing, change jobs without notifying your lender, or co-sign on another person's loan. Each of these can affect your credit score, debt-to-income ratio, or asset verification before your loan closes.
