Mortgage Basics

What a Mortgage Payment Is Actually Made Of

A monthly mortgage payment is rarely just one number — it's usually four things bundled together, commonly abbreviated PITI.

A loan with an HOA adds a fifth line item, though HOA dues are paid to the association directly rather than bundled into the mortgage payment itself. You can model all of this — principal, interest, taxes, insurance, and HOA — with your own numbers on the mortgage payment calculator.

How Lenders Decide What You Qualify For

Underwriting comes down to three things: credit history, income, and debt-to-income ratio (how much of your gross monthly income already goes to existing debt payments). Conventional and government-backed programs each set their own guidelines for all three, and a stronger number in one area can sometimes offset a weaker one elsewhere.

The part that trips people up is documentation, not qualification itself. A W-2 employee's income is straightforward to verify. A self-employed borrower's tax returns often understate real cash flow after write-offs, which is exactly what bank statement loans exist to solve — qualifying off actual bank deposits instead. A real estate investor can skip personal income documentation entirely with a DSCR loan, qualified against the property's own rental income. And a borrower who files taxes with an ITIN instead of a Social Security number has a real path through an ITIN loan rather than being treated as unqualifiable by default.

How the Property Itself Affects Financing

Qualification isn't just about the borrower — the property matters too. A single-family home on its own lot is the most straightforward case for most programs. Condos add an extra layer: the lender also reviews the condo association's finances and insurance, since a poorly funded HOA is a real risk to the property's value. A multi-family property (two to four units) can still qualify for owner-occupant financing if you live in one unit, and rental income from the other units can sometimes count toward qualification. Raw land or a home that needs significant work before it's livable typically falls outside standard financing entirely — that's what land loans, new construction loans, and hard money exist to cover instead.

How Much Down Payment You Actually Need

There's no single right answer here — it depends on the program:

• FHA loans — as low as 3.5% down, with flexible credit-score guidelines.
• Conventional loans — as low as 3% down for qualifying buyers, without FHA's upfront and lifetime mortgage insurance.
• VA loans — $0 down for eligible active-duty service members, veterans, and surviving spouses, with no monthly mortgage insurance.
• USDA loans — $0 down for eligible buyers in designated suburban and rural areas.

On top of any of these, down payment assistance programs can cover part or all of what's needed out of pocket for buyers who qualify — often the difference between waiting another year to save and buying now.

Reserves: The Money You Need Beyond the Down Payment

Down payment and closing costs aren't the only cash a lender wants to see. "Reserves" refers to money left in the bank after closing — typically measured in months of future mortgage payments a program wants documented as a cushion. Requirements vary by program and by how the rest of your file looks; a stronger credit profile can sometimes offset lighter reserves, and vice versa. It's one more reason the honest answer to "how much do I need saved" depends on your specific file rather than a single number.

Fixed-Rate vs. Adjustable-Rate, Conceptually

A fixed-rate loan locks in the same interest rate for the entire loan term — the payment amount for principal and interest never changes. An adjustable-rate mortgage (ARM) starts with a rate that's fixed for an initial period, then adjusts periodically based on market conditions afterward. Neither is universally better — it depends on how long you plan to keep the loan and how much payment certainty matters to you. This is a conversation for a loan officer working your specific numbers, not something to decide from a general guide.

What a Mortgage Broker Does Differently

A bank can only offer its own loan products. A mortgage broker works with multiple programs and matches a borrower's actual situation — income type, credit history, down payment, property type — to whichever one fits, rather than fitting the borrower into whatever the bank happens to sell. That matters most for anyone who doesn't fit a standard conventional file: self-employed borrowers, investors, ITIN filers, foreign nationals, and buyers rebuilding credit after a setback all have a real path through a program built for their situation specifically.

Entrust Home Lending also underwrites files in-house rather than routing them through an outside processing center, and every loan officer on the team speaks Spanish and English — so a borrower can work the entire process, in whichever language they're most comfortable in, with the person actually reviewing their file.

Why This Site Never Shows You a Rate

Rates move constantly and depend on your specific credit profile, loan program, loan amount, and the day you lock — a number posted on a website is generic at best and stale within hours at worst. Rather than publish a rate that isn't really yours, every calculator on this site asks you to enter your own rate estimate so you can see how a payment actually changes with different assumptions. When you're ready for a real number, request a rate and a loan officer will give you one based on your actual file, not a marketing figure.

What a Higher Loan Amount Changes

Every county has a conforming loan limit set for conventional financing — borrow above it and the loan becomes a jumbo loan instead, with its own underwriting guidelines built around a larger loan amount and generally stronger credit and reserve requirements. This comes up most often on higher-priced homes or in higher-cost markets, and it's worth knowing the distinction exists before assuming every purchase qualifies under the same conventional rules.

If a File Doesn't Qualify the First Time

A denial isn't necessarily the end of the road — it's usually a specific, fixable reason: a debt-to-income ratio that's too high, a credit score just under a program's threshold, or income that wasn't documented the way the program required. A loan officer who reviews the actual reason can often point to either a different program built for that exact situation (non-QM financing exists specifically for files that don't fit a conventional or FHA box) or a concrete list of what would need to change to qualify later. That second outcome is more common than people expect, and it's a meaningfully different answer than a flat no.
