❓ Frequently Asked Questions (FAQs)
1. What is mortgage pre-approval?
Pre-approval is a lender’s conditional offer to loan you a specific amount based on your financial data. It is not a guarantee but gives you strong buying power.
2. Does using this calculator affect my credit score?
No, this tool uses self-reported data and does not involve a credit check.
3. What credit score is needed for mortgage pre-approval?
Most lenders require a minimum score of 620. Higher scores open access to better rates and higher DTI limits.
4. What is considered a good debt-to-income ratio?
A DTI under 36% is ideal. However, some lenders allow up to 45% for applicants with excellent credit.
5. How much should I put down on a house?
A minimum of 3% is common for first-time buyers. However, 10–20% is recommended for better terms and to avoid private mortgage insurance (PMI).
6. Is the interest rate I enter guaranteed?
No, this rate is an estimate. Your actual rate will depend on your credit profile, loan type, and market conditions.
7. What happens if my DTI is too high?
Lenders may deny pre-approval. You can lower your DTI by reducing debt or increasing income.
8. Can I include rental income or bonuses in my annual income?
Yes, as long as it’s documented and consistent. Lenders will typically average these over 1–2 years.
9. How is monthly payment calculated?
Based on loan amount, interest rate, and term using standard amortization formulas.
10. What loan term is best: 15, 20, or 30 years?
Shorter terms mean higher monthly payments but less interest over time. 30 years offers lower payments and is most common.
11. What costs are NOT included in this calculator?
Property taxes, homeowners insurance, PMI, and HOA fees are not factored in but may affect your real budget.
12. Will this tool tell me my exact approval amount?
No. This is an estimate. Only a lender can give you an official pre-approval after reviewing documents and your credit report.
13. Can I use this calculator for FHA or VA loans?
Yes, but FHA and VA loans may have different DTI and down payment rules not reflected here.
14. Can I get pre-approved with student loans?
Yes. As long as your total DTI remains within lender limits, you can still qualify with student debt.
15. Should I wait until I’m pre-approved to look at houses?
Yes, it’s best to know your range before shopping. This helps avoid wasting time on homes outside your budget.
16. What if my financial situation changes after using the calculator?
Update the tool with your new income, debt, or credit score to recalculate your eligibility.
17. Is this calculator accurate?
It uses standard industry formulas to provide reliable estimates but cannot replace a lender’s official evaluation.
18. Can I use this for investment properties?
This tool is designed for primary residence estimates. Investment property pre-approvals often require different calculations.
19. How often should I check my pre-approval range?
Check whenever your income, debts, or credit score changes, or if interest rates shift significantly.
20. What’s the next step after using this calculator?
Contact a mortgage lender with your results to begin the formal pre-approval process.
