Your credit score is a three-digit number — typically between 300 and 850 — that summarizes how reliably you've paid back debt in the past. Lenders use it as a quick read on how risky it is to lend you money for a home.
The most common score used in mortgage lending is the FICO score. When a lender pulls your credit, they'll actually pull scores from all three major credit bureaus — Experian, Equifax, and TransUnion — and use the middle score for their decision.
Your score is affected by five main factors: payment history (the biggest one), how much of your available credit you're using, length of credit history, types of credit you have, and how recently you've applied for new credit.
Different loan programs have different floor requirements. Here's how the most common first-time buyer loan types stack up:
| Loan Type | Minimum Score | Min. Down Payment | Notes |
|---|---|---|---|
| Conventional | 620 | 3–5% | Best rates above 740 |
| FHA | 580 | 3.5% | 500–579 requires 10% down |
| VA | No official minimum | 0% | Lenders often require 580–620 |
| USDA | 640 (typically) | 0% | Rural/suburban areas of Idaho |
| Idaho Housing | 620 | As low as 0–3% | First-time buyer programs available |
These are lender minimums — not guarantees of approval. Lenders also look at your income, debt-to-income ratio, employment history, and the property itself. A score above the minimum gets your foot in the door. Everything else determines whether you walk through it.
Here's where credit score really moves the needle — not just on whether you qualify, but on what you pay every month for the life of the loan. A difference of 40 points can mean hundreds of dollars per year in interest.
| Score Range | Rating | What to Expect |
|---|---|---|
| 740 and above | Excellent | Best available rates, most loan options open |
| 700–739 | Good | Strong options, slightly higher rate than top tier |
| 660–699 | Fair | Qualifying is straightforward; rate will be higher |
| 620–659 | Borderline | Conventional possible; FHA may be better option |
| 580–619 | Low | FHA with 3.5% down; fewer options, higher rate |
| Below 580 | Very Low | FHA requires 10% down; work on score first |
If your score isn't where you want it to be, the good news is that credit scores respond to intentional action faster than most people expect. A focused 3–6 month effort can meaningfully move your number.
One of the most common mistakes first-time buyers make is opening a new credit card or financing a major purchase — furniture, a car, appliances — in the months before or during the loan process. Even if the debt seems manageable, new credit can change your debt-to-income ratio and put your loan at risk.
Idaho has resources specifically for first-time buyers that conventional lenders don't always lead with. Idaho Housing and Finance Association (IHFA) administers several programs that offer down payment assistance, lower interest rates, and more flexible credit requirements for qualified buyers.
These programs are income- and purchase-price limited, meaning there are caps on how much you can earn and how expensive a home you can buy. But for many Treasure Valley first-time buyers — especially those purchasing in Nampa, Caldwell, or Meridian — these programs open doors that standard lending doesn't.
The best way to find out which programs you qualify for is to talk to a local lender who works with these programs regularly. That's one of the first connections we make for buyers who come through this program — getting you in front of the right lender before you've spent a single hour looking at homes.

This is a real question and it deserves a real answer, not a sales pitch. The honest answer is: it depends on the math.
If you're sitting at a 610 and could realistically get to 660 in four to six months, the rate improvement might save you more over the life of the loan than you'd gain from buying today. If you're at 680 and the difference to 720 is marginal on the rate, waiting may cost you more in rising home prices than you'd save in interest.
That calculation is specific to your situation — your income, your target price range, what the Treasure Valley market is doing. It's not a question you should try to answer with a calculator on the internet. It's a conversation worth having with a lender and an agent who know this market.

No. Checking your own score is a "soft inquiry" and has no effect on your score. When a mortgage lender pulls your credit, that's a "hard inquiry" and may cause a small, temporary dip — typically 5 points or less. Multiple lenders pulling your credit within a short window (usually 14–45 days) are generally counted as a single inquiry by scoring models.
Yes. With a 580 score you can qualify for an FHA loan with 3.5% down. FHA loans are backed by the federal government, which allows lenders to approve buyers who don't qualify for conventional financing. You'll pay mortgage insurance (PMI) as part of the loan, but for many first-time buyers in the Treasure Valley, this is the most direct path to homeownership.
Your credit report is the full history — every account, every payment, every inquiry. Your credit score is a number calculated from that report. Lenders look at both. Your report can show things your score doesn't, like a pattern of on-time payments that might give a lender more confidence despite a lower number.
Paying down a large credit card balance can show results within one to two billing cycles. Establishing a consistent pattern of on-time payments takes longer — typically 6–12 months to see meaningful change. Negative items like late payments or collections take 7 years to age off a report, though their impact on your score lessens over time.
A mortgage pre-approval involves a hard inquiry, which may temporarily lower your score by a few points. This is normal and expected — lenders understand it. The impact is minor and short-lived. Shopping multiple lenders within a short window is treated as a single inquiry by most scoring models, so don't let concern about your score stop you from comparing rates.
