Choosing a mortgage is often the biggest financial decision a first-time buyer makes, and it lands in the same two weeks as packing boxes, scheduling inspections, and arguing about paint colors. The loan you pick sets your down payment, your monthly payment, how long you pay mortgage insurance, and how easily you can refinance later. Pick well and the house feels comfortable. Pick badly and you’re handing over an extra $150 to $250 every month for years.
There isn’t one best mortgage for everyone. There’s a best mortgage for your credit score, your savings, and how long you plan to stay in the house. Here’s how to narrow it down without wading through a lender’s sales pitch.
What You Qualify For Sets the Shortlist
Before comparing loan programs, know the two numbers underwriters care about most: your credit score and your debt-to-income ratio. The score decides which programs you can touch and what your mortgage insurance costs. DTI, which is all your monthly debt payments divided by your gross monthly income, decides how much house you can buy. Most lenders want 43% or less, though many will stretch to 50% if you have compensating factors like a large down payment.
Rough qualification floors right now:
- Conventional loans: 620 credit score minimum, 3% down for first-time buyers
- FHA loans: 580 score for 3.5% down, or 500 to 579 if you put 10% down
- VA loans: lenders set their own bar, usually 580 to 620, with 0% down
- USDA loans: 640 score is common, 0% down, property must sit in an eligible rural area
You can get FHA approval with a 580 score and a thin credit file. Conventional approval at 620 is possible, but the pricing gets steep fast. That gap matters more than any marketing claim about which loan is “best.”
The Four Loans First-Time Buyers Actually Use
Conventional loans
A conventional loan isn’t backed by the government; it’s bought by Fannie Mae or Freddie Mac. Lenders set tighter rules, but costs are usually lower once you’re in. Three percent down on a $350,000 house is $10,500. Private mortgage insurance runs roughly 0.5% to 1.5% of the loan amount per year depending on your score, so budget $150 to $250 a month at the start.
The upside is that PMI is temporary. Once your balance drops to 80% of the home’s value, you can ask the lender to remove it, often with a new appraisal, and it falls off automatically at 78% of the original value. On a normal schedule with modest appreciation, that’s usually somewhere between year six and year nine.
FHA loans
FHA loans are the workhorse for buyers with thinner credit. You need 3.5% down at a 580 score, and the seller can contribute up to 6% toward closing costs. The catch is mortgage insurance, and it’s bigger than most people expect. There’s an upfront premium of 1.75% of the loan that gets added to your balance, plus an annual premium of 0.55% on a 30-year loan with less than 10% down.
On a $340,000 base loan that annual premium runs about $1,870, or $156 a month. Unlike PMI, FHA insurance doesn’t vanish at 20% equity. Put less than 10% down and you pay it for the life of the loan unless you refinance into a conventional loan later. That refinance is often the right move once your score climbs.
VA loans
If you or your spouse has served, this is usually the strongest option on the board. Zero down payment, no monthly mortgage insurance, and the seller can cover your closing costs. You’ll pay a funding fee of 2.15% on your first use with nothing down, which can be rolled into the loan, and the fee is waived entirely for veterans with a service-connected disability.
USDA loans
Easy to overlook because the name sounds agricultural. USDA loans are 0% down and available in towns with populations up to 35,000, which covers more ground than people expect. Income limits apply, generally 115% of the area median, and you’ll pay a 1% upfront guarantee fee plus 0.35% annually. On a $300,000 loan that’s about $1,050 a year, roughly half of what FHA charges.
Fixed Rate or Adjustable? Assume Fixed Until Proven Otherwise
An adjustable-rate mortgage gives you a lower rate for a set period, usually five, seven, or ten years, then adjusts based on a market index. On a $400,000 loan, a 7/6 ARM might start a full percentage point below a 30-year fixed, saving roughly $4,000 a year at the start.
That’s real money, and it works if you’re confident you’ll sell or refinance before the fixed period ends. It stops working the moment life changes. Job offers move, rates move, and the house you swore you’d leave in five years turns out to be the one your kid refuses to leave.
Term Length Changes More Than the Payment
Everyone defaults to 30 years, and for most first-time buyers that’s right. The payment is smaller and the extra cash flow matters when you’re furnishing a house and rebuilding savings. Still, run the numbers on a 15-year before you dismiss it.
On a $350,000 loan, a 30-year at 6.5% costs about $2,212 a month in principal and interest. A 15-year at roughly 5.9% costs about $2,935. That’s $723 more each month, but total interest lands near $446,000 versus about $178,000. A $268,000 difference for the same house.
Most buyers can’t swing the higher payment in year one. Some take the 30-year and make extra principal payments when money allows, which shortens the term without locking in the bigger obligation.
Down Payment Assistance Is the Most Overlooked Money in the Room
HUD maintains a list of more than 2,000 down payment assistance programs run by states, counties, and cities. Many are forgivable second mortgages, silent seconds, or straight grants. A typical structure: 3% to 5% of the purchase price at 0% interest, forgiven entirely after five years of living there as your primary residence.
Stack one of those with a conventional or FHA loan and a buyer with $8,000 saved can close on a $350,000 house. Ask your loan officer which programs you qualify for by zip code, then check your state housing finance agency’s website yourself. Plenty of lenders only push the programs they happen to offer.
Two Buyers, Two Different Answers
Buyer A has a 680 score and $15,000 saved on a $350,000 purchase. FHA gets her in with 3.5% down, but the permanent $160 monthly insurance premium adds up to roughly $57,000 over 30 years if she never refinances. Conventional 97 needs $10,500 down with PMI near $200 a month that disappears in about eight years. Conventional wins if she can handle the slightly higher payment now.
Buyer B has a 590 score and $9,000 saved. Conventional pricing at that score is brutal, and many lenders won’t approve it. FHA is the realistic path, with a plan to improve his score and refinance in two or three years. For him, FHA isn’t a compromise. It’s the door.
Ask These Questions Before You Lock
The rate gets all the attention, but the structure is where money hides. Bring this list to your lender:
- What’s my total monthly payment including taxes, insurance, HOA dues, and mortgage insurance?
- How long will I pay mortgage insurance, and what triggers it to end?
- Are lender credits available if I accept a slightly higher rate?
- Which down payment assistance programs do I qualify for in my county?
- What would my payment be at 15 years, and what would it be on an ARM?
- How much cash do I need at closing, including prepaid taxes and insurance?
Get those six answers in writing from two lenders and compare them side by side. The lowest rate often isn’t the cheapest loan, and the smallest down payment isn’t always the one that costs you least over time. The right mortgage is the one that fits your score, your savings, and the number of years you can honestly picture yourself in that house.
