First-Time Homebuyer's Complete Guide to Choosing a Mortgage

March 16, 2026

Quick Answer

First-time homebuyers should start by understanding the two most common mortgage types: FHA loans (3.5% down, 580+ credit score) and conventional loans (3-5% down, 620+ credit score). Your credit score, savings, and income will determine which option saves you the most money. The right choice could save you tens of thousands of dollars over the life of your loan.

Key Takeaways

  • FHA loans offer the easiest qualification with 3.5% down and a 580 minimum credit score
  • Conventional loans typically cost less over time for borrowers with credit scores above 700
  • You need to budget for both down payment (3.5-20%) and closing costs (2-5%)
  • Get pre-approved before house hunting to know exactly what you can afford
  • First-time buyer programs can help with down payments and closing costs
  • Your debt-to-income ratio should stay below 43% for most loan programs

Step 1: Assess Your Financial Health

Before you start looking at homes, take an honest look at your finances:

Check Your Credit Score

Your credit score is the single most important factor in determining which loan type you qualify for and what interest rate you will receive. Get free copies of your credit report from all three bureaus at AnnualCreditReport.com.

  • Below 580: You may struggle to qualify for any mortgage. Focus on building credit first.
  • 580-619: FHA loans are your best (possibly only) option. Expect higher rates.
  • 620-679: You can choose FHA or conventional. Compare costs carefully.
  • 680-739: Conventional loans become more attractive with better PMI rates.
  • 740+: You qualify for the best rates on conventional loans.

Calculate Your DTI Ratio

Your debt-to-income ratio tells lenders how much of your income goes toward debt payments. Add up all monthly debt payments (student loans, car payments, credit card minimums, etc.) and divide by your gross monthly income.

For example, if you earn $6,000/month and have $1,500 in debt payments, your DTI is 25%. Most loan programs allow a maximum housing payment that keeps your total DTI at or below 43%.

Save for Down Payment and Closing Costs

You will need savings for two things:

Down payment: 3.5% (FHA) to 20% (conventional without PMI) Closing costs: 2-5% of the home price

For a $350,000 home with 5% down:

  • Down payment: $17,500
  • Closing costs: $7,000-$17,500
  • Total needed: $24,500-$35,000

Step 2: Choose Your Loan Type

FHA Loan Pros and Cons for First-Time Buyers

Pros:

  • Only 3.5% down required
  • Credit scores accepted from 580
  • More forgiving of past credit issues
  • Allows higher DTI ratios
  • Down payment can be a gift

Cons:

  • Mandatory mortgage insurance for the life of the loan (with <10% down)
  • Upfront MIP of 1.75%
  • Only for primary residences
  • Stricter property requirements

Conventional Loan Pros and Cons for First-Time Buyers

Pros:

  • No upfront mortgage insurance fee
  • PMI cancels at 78% LTV
  • Can be used for any property type
  • Higher loan limits
  • Lower total cost over loan life (with good credit)

Cons:

  • Higher credit score required (620+)
  • Stricter DTI requirements
  • Larger down payment typically needed
  • PMI is expensive with lower credit scores

Step 3: Get Pre-Approved

Getting pre-approved gives you a clear picture of how much home you can afford and shows sellers you are a serious buyer. You will need:

  • Two years of W-2s or tax returns
  • Recent pay stubs (30 days)
  • Bank statements (2-3 months)
  • Photo ID
  • Authorization for credit check

Get pre-approved with at least two or three lenders to compare offers. Even a small difference in interest rate can save you thousands over the life of the loan.

Step 4: Find Your Home and Make an Offer

Work with a real estate agent who understands first-time buyer programs. When you find the right home:

  1. Make an offer within your pre-approved budget
  2. Include contingencies for inspection, appraisal, and financing
  3. Negotiate closing cost credits from the seller when possible
  4. Be prepared to act quickly in competitive markets

Step 5: Close on Your Home

The closing process typically takes 30-45 days from accepted offer. During this time:

  • Complete the mortgage application with your chosen lender
  • Lock your interest rate
  • Get a home inspection and appraisal
  • Secure homeowners insurance
  • Review the closing disclosure carefully
  • Bring your down payment and closing costs to closing
