How to Secure a Home Loan: What Lenders Actually Look At

Most people approach a home loan application the same way they approach a job interview — they show up, hope for the best, and feel like the outcome is largely out of their control. It isn’t. Lenders evaluate a specific set of factors, every one of which you can influence before you walk through the door. Understanding what those factors are — and what the numbers actually need to look like — is what separates buyers who secure favorable mortgage terms from those who pay significantly more over 20 or 30 years.

This guide covers the full picture: eligibility criteria, how much you can borrow, the fixed vs. floating rate decision, and how to choose between going directly to a lender versus working with a mortgage broker.

What Lenders Look at When You Apply

According to the Consumer Financial Protection Bureau, lenders evaluate five primary factors in every mortgage application:

• Income and employment stability — Lenders want to see consistent income history, typically at least two years of employment in the same field. Self-employed borrowers need to show two years of tax returns.
• Credit score — The higher your score, the lower your interest rate. Most conventional lenders want 620 or above to approve an application; 750+ gets you the best rates.
• Debt-to-income ratio (DTI) — Your total monthly debt payments (including the new mortgage) should be below 43% of your gross monthly income. Many lenders prefer 36% or lower.
• Down payment — Most conventional loans require 10–20% of the property’s value upfront. Some government-backed loans allow as little as 3.5% (FHA) or 0% (VA loans for eligible veterans).
• Property value — The lender will order an independent appraisal. If the property appraises below the purchase price, you’ll need to cover the difference or renegotiate.

How Much Home Loan Can You Get?

The standard lending formula allows you to borrow 75–90% of the property’s appraised value, meaning your down payment covers the remaining 10–25%. The actual loan amount is also limited by your income — lenders calculate how large a monthly payment your income can support, then work backward to the maximum loan amount.

A useful rule of thumb: most lenders approve loans up to roughly 4–5x your annual gross income for borrowers with strong credit and low existing debt. A household earning $100,000 per year might qualify for a $400,000–$500,000 mortgage, assuming minimal other debt. Use this as a rough guide, not a guarantee — actual approval depends on your complete financial picture.

Credit Score Requirements

Your credit score is the single most controllable factor in your mortgage rate. The difference between a 680 and a 760 credit score can translate to 0.5–1% difference in interest rate — which on a $300,000 30-year mortgage means paying $30,000–$60,000 more over the life of the loan.

Score benchmarks by loan type:

• 760+ — Best available rates on conventional mortgages
• 700–759 — Good rates, competitive but not best tier
• 660–699 — Approved at most lenders but with higher rates
• 620–659 — Minimum for most conventional loans; limited lender options
• Below 620 — Conventional loans typically unavailable; FHA may still be an option

If your score is below your target, the most effective improvement strategies are: paying down revolving credit card balances (this moves the needle fastest), resolving any collection accounts, and avoiding new credit applications in the 6–12 months before applying. The difference between starting with bad credit and building it up is significant — understanding no credit vs bad credit clarifies which situation you’re actually in and how lenders treat each one differently.

Fixed Rate vs Floating Rate: How to Choose

The right choice depends almost entirely on your circumstances and risk tolerance.

Fixed rate mortgages lock your interest rate for a specified period — typically 2, 5, or 10 years, or the full loan term in the US. Your monthly payment doesn’t change regardless of what happens to interest rates. The tradeoff: fixed rates are usually higher than floating rates at the time of borrowing, and early repayment often carries penalties.

Floating (variable) rate mortgages move with market interest rates. When rates fall, your payment falls. When rates rise, your payment rises. Floating rates are typically lower at the point of borrowing, and they usually have no prepayment penalties — useful if you plan to pay extra or refinance.

The practical guidance: if you’re buying in a rising rate environment and plan to stay in the home long-term, a fixed rate provides certainty. If rates are high and expected to fall, a floating rate lets you benefit from decreases. If you’re uncertain, a split loan — part fixed, part floating — hedges both ways.

Mortgage Broker vs Direct Lender: Which Is Right for You?

Going directly to your bank is simpler but limits you to that bank’s products. A mortgage broker has access to multiple lenders — banks, credit unions, and non-bank lenders — and can compare rates and terms across all of them simultaneously. Brokers are paid by the lender (not by you in most cases), so their service is typically free to borrowers.

Brokers are particularly valuable if your financial situation is non-standard — self-employment, gaps in employment history, imperfect credit, or a large loan relative to income. Standard borrowers with strong credit may find they get competitive rates directly from their bank with less paperwork.

According to Bankrate’s mortgage research, shopping your loan to at least three lenders — whether directly or through a broker — saves an average of $1,500 in the first year alone on a typical US mortgage.

What to Prepare Before You Apply

Most delays in the mortgage process come from missing documentation. Have these ready before you begin:

• Last two years of tax returns (personal and business if self-employed)
• Last two to three months of bank statements
• Recent pay stubs (30 days)
• Investment account statements
• Photo ID and Social Security number
• List of all current debts with monthly payment amounts
• Employment history for the past two years

Once you’re approved and moving toward purchase, planning for what comes next matters too. Home renovation ideas that add value are worth researching before you close — understanding which improvements deliver ROI helps you prioritize any work the new property needs.

Frequently Asked Questions About Securing a Home Loan

What is the minimum credit score for a home loan?

For most conventional loans, lenders require a minimum credit score of 620. FHA loans (government-backed) accept scores as low as 580 with a 3.5% down payment, or 500 with a 10% down payment. The minimum score to access competitive interest rates is closer to 740–760. Every 20–30 points below that tier typically means a higher rate.

How much deposit do I need for a home loan?

Most conventional loans require 10–20% of the purchase price as a down payment. Putting down less than 20% usually requires private mortgage insurance (PMI), which adds to your monthly cost. Government-backed loans (FHA, VA, USDA) allow smaller down payments for qualifying borrowers — as low as 0% for VA loans for eligible veterans.

Should I choose a fixed or floating interest rate?

Fixed rates offer payment certainty, which is valuable in a rising rate environment or if you plan to hold the loan long-term. Floating rates tend to start lower and benefit borrowers when rates fall, but payments can increase. A split loan — part fixed, part floating — is a practical middle ground. Your decision should be based on current rate trends, how long you plan to hold the property, and your tolerance for payment variability.

What is the maximum repayment term for a home loan?

Most lenders offer maximum terms of 25–30 years, subject to your age at the time of application. Lenders typically require that the loan be repaid before or at retirement age (usually 65–70). Longer terms reduce monthly payments but increase total interest paid significantly. A 30-year mortgage typically costs 2–3x the original loan amount in total interest at standard rates.
