Credit Score to Buy a House: Complete Guide 2026
You do not need perfect credit to buy a home in Las Vegas. FHA loans accept scores as low as 580, conventional loans start at 620, and FICO data shows the median credit score for closed purchase mortgages was 745 in 2025, meaning roughly half of buyers close with scores below that threshold. This guide tells you exactly what score each loan type requires, how your score moves your rate, and which actions raise it fastest.
Key Takeaways
- FHA minimum: 580 (3.5% down) or 500 (10% down)
- Conventional minimum: 620 with most lenders
- VA and USDA: no official floor, lenders typically want 620+
- Each 20-point score improvement can lower your rate 0.125-0.25%, saving thousands over the life of the loan
- CFPB research shows credit utilization and on-time payments are the two fastest levers buyers control
What Credit Score Do You Need to Buy a House in 2026?
The short answer: 580 for FHA, 620 for conventional, and 640 for USDA automated underwriting. According to HUD guidelines, FHA allows 3.5% down at 580 and requires 10% down for scores between 500-579. Most Las Vegas lenders layer their own overlays on top of agency minimums, so practical floors run slightly higher.
| Loan Type | Agency Minimum | Typical Lender Floor | Down Payment |
|---|---|---|---|
| FHA | 580 | 580-600 | 3.5% |
| Conventional | 620 | 620-640 | 3-20% |
| VA | None | 580-620 | 0% |
| USDA | 640 | 640 | 0% |
| Jumbo | 700 | 720-740 | 10-20% |
Nevada lenders pull all three bureaus (Experian, Equifax, TransUnion) and use your middle score. On joint applications, they use the lower middle score between borrowers.
Citation: HUD’s official FHA handbook sets the 580/500 thresholds for down payment tiers. Fannie Mae’s Selling Guide sets 620 as the conventional floor. Individual lenders may impose higher overlays. Always confirm with your loan officer.
How Your Credit Score Moves Your Mortgage Rate
A 60-point score difference on a $450,000 loan can cost $180-$300 more per month. The CFPB Loan Estimate comparison tool shows rate spreads by score tier. For Nevada borrowers in 2026, typical 30-year fixed rates by FICO band run approximately:
| FICO Range | Approx. Rate | Monthly Payment ($450K) | 30-Yr Interest Cost |
|---|---|---|---|
| 760-850 | 6.50% | $2,844 | $573,840 |
| 720-759 | 6.75% | $2,919 | $601,240 |
| 680-719 | 7.00% | $2,995 | $628,200 |
| 640-679 | 7.50% | $3,149 | $683,640 |
| 580-639 | 8.00% | $3,305 | $739,800 |
The gap between a 580 score and a 760 score on that same loan: $461 per month, $166,000 over 30 years.
Improving your score before you apply is not just helpful – for many buyers in the Las Vegas market, it is the highest-ROI financial move available. Explore how your debt-to-income ratio interacts with your score to determine the rate you actually qualify for.
What Makes Up Your Credit Score
FICO scores range from 300 to 850. The five factors and their weights:
- Payment history (35%) – Any 30-day late payment in the past 24 months is a red flag
- Amounts owed / utilization (30%) – Total balances as a percentage of total credit limits
- Length of credit history (15%) – Average age of all accounts
- New credit (10%) – Hard inquiries from new applications
- Credit mix (10%) – Having revolving credit (cards) plus installment loans (auto, student)
For mortgage purposes, lenders scrutinize the last 12-24 months of payment history most heavily.
Citation: FICO publishes score factor weights at myfico.com. Mortgage lenders use FICO Score 2 (Experian), FICO Score 5 (Equifax), and FICO Score 4 (TransUnion) – not the generic FICO 8 used by most free score services. Your mortgage score may differ from what Credit Karma shows.
How to Improve Your Credit Score Before Buying
The fastest single action: reduce revolving credit utilization below 10%. Experian research shows utilization is the most actionable variable because changes reflect within one billing cycle. Here is what actually moves the needle, ranked by speed:
30-60 days:
- Pay credit card balances down to under 10% of each card’s limit
- Request a credit limit increase (does not require hard pull at most issuers)
- Become an authorized user on a family member’s old, low-utilization card
60-90 days:
- Dispute errors on all three bureau reports (free at AnnualCreditReport.com)
- Settle any collection accounts – newer FICO models ignore paid collections entirely
- Establish a new installment loan only if your credit mix has no installment history
3-6 months:
- Build 6 consecutive on-time payments after any late payment history
- Let new hard inquiries age off (full impact fades after 12 months)
What NOT to do before applying:
- Do not close old credit cards – this shortens history and raises utilization
- Do not open new cards or auto loans 3-6 months before applying
- Do not co-sign any loan for someone else
- Do not make large cash deposits without documenting the source
Credit Score Requirements for First-Time Buyers in Nevada
Nevada’s Home Is Possible program and Clark County DPA programs generally align with FHA and conventional minimums. If you are using down payment assistance in Las Vegas, most programs require at minimum a 640 score to stack DPA on top of an FHA or conventional loan.
The Nevada Housing Division sets DPA program credit score floors. CBC Mortgage’s Chenoa Fund – one of the most widely used DPA options in the valley – requires 620 for most products and 640 for forgivable second mortgage options. More detail on that program is in our Chenoa Fund complete guide.
What Lenders Look at Beyond Your Credit Score
Your score gets you in the door, but approval depends on the full picture:
Debt-to-income ratio (DTI): Most conventional lenders cap at 45% back-end DTI; FHA allows up to 57% with compensating factors. Learn more in our DTI mortgage guide.
Employment: Two years in the same field is the standard. Las Vegas hospitality workers with seasonal gaps can document with tax returns.
Assets: Lenders want 2-3 months of PITI (principal, interest, taxes, insurance) in reserves after closing.
Loan-to-value: Larger down payments compensate for lower scores. A 680 score with 20% down gets better terms than a 720 score with 3% down.
Also factor in how points affect your rate. Buying down your rate with mortgage points can make sense once your score qualifies you for a loan – see our mortgage points guide for the math.
Closing Costs and Credit Score Interaction
Higher credit scores sometimes unlock lender credits toward closing costs. Some lenders offer no-fee options at higher rate tiers in exchange for reduced upfront costs – a tradeoff worth modeling with your loan officer. Budget 2-5% of the purchase price for closing expenses regardless of credit tier.
Frequently Asked Questions
Q: Can I buy a house with a 580 credit score in Las Vegas? Yes. FHA loans allow 580 with 3.5% down. Several Nevada lenders actively originate FHA loans at 580. You will pay mortgage insurance premium (MIP), which adds roughly 0.55% annually to your loan balance.
Q: Will shopping for a mortgage hurt my credit score? Multiple mortgage hard pulls within a 45-day window count as a single inquiry under FICO scoring logic. Shop freely within that window without extra damage.
Q: How long does it take to go from 580 to 620? With aggressive utilization paydown and no derogatory items added, 3-4 months is realistic for a 40-point gain. Adding an authorized user on a well-aged account can compress that to 30-60 days.
Q: Does checking my own credit score lower it? No. Soft inquiries from checking your own score never affect your FICO score.
Q: What credit score do I need for a $500,000 house? The loan amount itself does not set the score requirement – the loan type does. A $500,000 FHA loan (within conforming limits) still requires 580. A $500,000 conventional loan still requires 620. A $500,000 jumbo loan typically requires 720+.
