Two lenders can quote you 6.5% and 6.4% on the same afternoon, and one of those loans will cost you roughly $28,000 more over 30 years on a $400,000 balance. Add a 1% origination fee, a different mortgage insurance schedule, and a five-year prepayment penalty buried on page three, and the gap widens fast. Comparing mortgage loan types is less about finding the famous “best” loan and more about building a repeatable way to price every option on identical terms.
Here is the method that holds up.
Put the APR next to the note rate, then ask what’s inside it
The annual percentage rate bundles the interest rate with most lender fees and discount points, then spreads those costs across the loan term. As a first pass it’s the fastest way to spot an offer that’s front-loading its profit.
A concrete example. Loan A is 6.50% with $1,200 in lender fees. Loan B is 6.375% with $4,800 in fees, including two discount points. On a $350,000 loan the lower rate saves about $31 a month, but you handed over $3,600 extra at closing. That’s a break-even of roughly nine and a half years. If you sell or refinance in five, Loan A wins despite the higher headline rate.
Where the APR lies to you
On an adjustable-rate mortgage, the APR assumes a projected path for rates after the fixed period ends. That’s a guess dressed up as a number. On a loan you plan to hold for three years, a 30-year amortization schedule tells you almost nothing about your actual cost. Use APR to eliminate obviously bad offers, not to crown a winner.
Build a five-line cost sheet for every loan
Comparing mortgage loan types only works if each quote is broken down the same way. For every offer you receive, write down these five rows:
- Rate, APR, and the lock date. A quote without a lock expiration is a marketing number, not a price.
- Lender fees in dollars. Origination, underwriting, processing, and discount points. Ignore percentages; ask for the cash figure.
- Loan-type-specific costs. Appraisal ($500–$800), FHA upfront mortgage insurance premium at 1.75% of the loan, the VA funding fee (0% to 3.3% depending on your service history and down payment), and the USDA guarantee fee.
- The monthly payment, unpacked. Principal and interest, property taxes, homeowners insurance, mortgage insurance, and HOA dues, listed separately.
- The exit cost. Prepayment penalties, and whether mortgage insurance falls off automatically at 78% loan-to-value or requires you to request it and pay for an appraisal.
Most buyers compare row four and skip rows two and five. Those two rows are where the unpleasant surprises live.
Term length moves the payment more than any rate shop will
On a $350,000 loan at 6.5%, the 30-year payment is about $2,212 a month. Stretch the same loan over 20 years and it’s $2,610. Fifteen years pushes it to $3,049. The 15-year saves you roughly $247,000 in interest over the life of the loan, and it costs $837 more every month to get there.
Now cross the terms, because this is where comparisons get interesting. A 30-year at 6.5% versus a 15-year at 5.9% produces about $268,000 less total interest, for $722 more per month. No amount of shopping a half-point of rate will match that. Term length is the biggest lever on the table, and it’s the one most people never pull because they fixate on the rate.
Fixed or adjustable depends on how long you’ll actually own the house
People plan to stay forever and move in seven years. If your realistic holding period is under a decade, price a 7/1 ARM against the 30-year fixed. A 7/1 at 5.75% versus a fixed at 6.5% saves about $170 a month on $350,000, or roughly $14,300 across seven years.
Then read the caps. A 5/2/5 structure on a 5.75% start means the rate could climb to 10.75% at the worst adjustment. That’s survivable if you’ve built equity and your income has grown. It’s a crisis if you’re stretched at closing. Price the worst-case payment before you sign, not the teaser.
Down payment and mortgage insurance reshape the whole loan
FHA lets you in at 3.5% down with a 580 score, but the annual mortgage insurance premium of 0.55% on a $350,000 loan runs about $1,925 a year, and on FHA loans with less than 10% down that premium typically lasts the entire loan term unless you refinance out. Conventional PMI at 5% down is often more expensive per month but terminates on its own once you reach 78% loan-to-value.
Do the arithmetic on both paths rather than assuming the lower down payment is the cheaper entry. The trade-offs between low down payment mortgage options and what they really cost below 20% are usually decided in year four, not at closing. If avoiding the monthly premium entirely matters more to you, there are several mortgage structures that skip PMI altogether, though each one trades that premium for something else.
Government-backed, conventional, and portfolio loans have different rulebooks
Conventional loans start at 3% down for first-time buyers and generally want a 620 score. FHA is more forgiving on credit and debt-to-income but charges insurance for life. VA gives eligible borrowers 0% down with a funding fee. USDA is 0% down with geographic and income limits. Portfolio and jumbo loans sit outside all of this, because the lender keeps the loan on its own books and can bend its own guidelines.
That flexibility matters most when your income is complicated. Two years of self-employment returns, K-1 income, or a commission-heavy pay structure can push you out of the automated approval engines entirely and into a portfolio product. The mortgage types that self-employed buyers can realistically get approved for are a narrower set than the advertised menu suggests, and comparing them against a conventional quote you can’t actually qualify for wastes weeks.
Read a comparison chart row by row, not column by column
Rate tables are designed to be skimmed. Resist that. Trace one row at a time: down payment requirement, credit floor, DTI ceiling, mortgage insurance rule, seller concession limits, property condition standards, and whether the loan is assumable. A loan that wins on down payment can lose badly on the appraisal and repair requirements, especially on a fixer-upper or a condo that isn’t warrantable.
A mortgage loan types comparison chart read properly, one row at a time, will flag those trade-offs in about ten minutes. Skimming the down payment column will hide them until you’re three weeks into a contract.
Ask every lender the same six questions
Consistency is what makes quotes comparable. Send identical questions in writing and keep the replies:
- Is this rate locked, until what date, and what does an extension cost?
- What is the total lender fee in dollars, including points?
- Does this loan carry a prepayment penalty or a seasoning requirement before refinancing?
- When exactly does mortgage insurance come off, and who pays for the appraisal to remove it?
- What is the worst-case monthly payment if the rate resets?
- Which document in my file is most likely to cause an underwriting delay?
Anyone who won’t answer in writing is telling you something useful about how the process will go.
Match the loan to your file, not to the rate table
A borrower with 12% down, a 712 score, two years of 1099 income, and $40,000 in student loans is not shopping the same market as a W-2 employee with 25% down. The loan that fits your documents and your timeline will beat the loan with the flashiest rate almost every time, because the flashy rate usually belongs to a scenario you can’t close on. The cheapest mortgage loan is a match between your file and a lender’s guidelines, not a product name.
So run the exercise properly. Get three Loan Estimates on the same day, for the same loan amount and the same projected closing date. Drop each one into a single spreadsheet using the five rows above. Whichever column is still standing after row five, and after the worst-case payment question, is your loan.
