Mortgage Basics in Minnesota: Loan Types, Rates & Terms Explained (2026)

Mortgage terminology can feel like its own language, and most buyers only really learn it while they're already deep in the process. This guide covers the fundamentals up front, so you walk into your first lender conversation already speaking the language — ideally before you get pre-approved, since that conversation goes much faster once you already know what a lender is asking about.

What a Mortgage Actually Is

A mortgage is a loan secured by the home you're buying — meaning the lender has a legal claim on the property until the loan is paid off. You repay it over a set term, most commonly 15 or 30 years, through monthly payments that include principal (what you borrowed) and interest (the cost of borrowing it), plus typically property taxes and insurance collected into an escrow account.

The Four Main Loan Types

Conventional Loans

Not insured or guaranteed by a government agency, conventional loans are the most common loan type and typically require stronger credit than government-backed options. Down payments can be as low as 3% for qualifying buyers, though PMI usually applies below 20% down.

FHA Loans

Insured by the Federal Housing Administration, FHA loans generally allow lower credit scores and smaller down payments (as low as 3.5%) than conventional loans. In exchange, FHA loans require mortgage insurance premiums that, unlike conventional PMI, often last for the life of the loan depending on your down payment.

VA Loans

Available to eligible veterans, active-duty service members, and some surviving spouses, VA loans are backed by the Department of Veterans Affairs and often require no down payment at all. Eligibility depends on service history — confirm your specific eligibility through the VA or a lender experienced with VA loans.

USDA Loans

Backed by the U.S. Department of Agriculture, USDA loans support eligible buyers in designated rural and some suburban-edge areas, often with no down payment required. Property location eligibility is specific and worth checking directly, since "rural" designations can include areas that don't feel especially rural.

Fixed-Rate vs. Adjustable-Rate Mortgages

Feature	Fixed-Rate Mortgage	Adjustable-Rate Mortgage (ARM)
Interest rate	Stays the same for the full term	Fixed for an initial period, then adjusts periodically
Payment predictability	Highly predictable	Predictable at first, can change later
Typical starting rate	Often slightly higher than an ARM's initial rate	Often lower for the initial fixed period
Best fit for	Buyers planning to stay long-term	Buyers planning to sell or refinance before the adjustment period

Private Mortgage Insurance (PMI): What It Is and When It Goes Away

PMI protects the lender, not you, and typically applies to conventional loans with less than 20% down. It's usually charged as part of your monthly payment until your loan balance drops to roughly 78-80% of the home's original value — at which point it can often be removed, either automatically or by request, depending on your servicer's process.

Rate Locks: Protecting Your Rate While You're Under Contract

When you lock your rate, your lender guarantees a specific interest rate for a set window — commonly 30 to 60 days — while your loan moves through processing. This protects you if rates rise during that time.

Debt-to-Income Ratio: The Number Lenders Care About Most

Your debt-to-income ratio (DTI) is your total monthly debt payments divided by your gross monthly income, expressed as a percentage. Lenders use it, alongside credit score and down payment, to determine how much you can borrow — and it's one of the more overlooked numbers by buyers estimating their own budget before talking to a lender.

Bottom Line

Understanding loan types, fixed vs. adjustable rates, PMI, rate locks, and debt-to-income ratio before you talk to a lender puts you in a much stronger position to compare offers and ask the right questions. None of this replaces an actual conversation with a licensed lender about your specific numbers — but walking in already familiar with the terminology tends to make that conversation faster and more useful.
