❓ Frequently Asked Questions

▶How much house can I afford based on my income?
Lenders use the 28/36 rule: housing costs shouldn't exceed 28% of gross monthly income, and total debt shouldn't exceed 36%. For example, with $6,000/month gross income ($72,000/year): Maximum housing cost: $6,000 × 0.28 = $1,680/month (includes mortgage principal, interest, property tax, insurance, HOA). Maximum total debt: $6,000 × 0.36 = $2,160/month. If you have $400/month in other debt (car, student loans, credit cards), housing is limited to $1,760/month. At 7% interest, 30 years, with $300/month for tax/insurance, your affordable mortgage payment is $1,460/month, supporting a loan of ~$219,000. With 20% down, you can afford a $274,000 home. However, conservative advisors suggest the 25% rule—housing costs under 25% of take-home (not gross) pay for financial flexibility and savings capacity.
▶What is debt-to-income ratio and why do lenders care about it?
Debt-to-Income ratio (DTI) measures your monthly debt payments as a percentage of gross income. Formula: DTI = (Total Monthly Debts ÷ Gross Monthly Income) × 100. Two types: (1) Front-end DTI: Housing costs only (P&I, tax, insurance, HOA). Lenders prefer under 28%. (2) Back-end DTI: All debt including housing, car, student loans, credit cards, child support. Lenders prefer under 36%, require under 43% for qualified mortgages. Example: Gross income = $7,000/month. Debts: $1,800 housing, $350 car, $200 student loan, $150 credit card = $2,500 total. Front-end DTI: $1,800 ÷ $7,000 = 25.7% (good). Back-end DTI: $2,500 ÷ $7,000 = 35.7% (acceptable). If DTI is 45%, you'll struggle to qualify or face higher interest rates. To improve DTI: increase income, pay off debt before applying, or consider a smaller house. A borrower with 38% DTI might qualify for $350,000, while 28% DTI might qualify for $450,000 at better rates.
▶How much should I save for a down payment and closing costs?
Total upfront costs include down payment + closing costs + reserves. For a $400,000 home: Down payment options: 3% FHA = $12,000 (requires PMI), 5% conventional = $20,000 (requires PMI), 20% = $80,000 (no PMI, better rates). Closing costs: 2-5% of purchase price = $8,000-$20,000 (includes lender fees, title insurance, appraisal, inspections, prepaid taxes/insurance). Cash reserves: Lenders want to see 2-6 months of mortgage payments in savings after closing (3-6% of purchase price) = $12,000-$24,000. Total needed for $400,000 home: 3% down = $12,000 + $14,000 closing + $15,000 reserves = $41,000. 20% down = $80,000 + $14,000 + $15,000 = $109,000. Don't forget moving costs ($2,000-$5,000), immediate repairs/furniture ($5,000-$15,000). Many first-time buyers underestimate total cash needed by $20,000-$40,000, causing closing delays or deal cancellations.
▶What other monthly costs besides the mortgage should I budget for?
True homeownership costs extend far beyond your mortgage payment (P&I). For a $350,000 home with $280,000 loan (20% down) at 7%: Mortgage P&I: $1,862/month. Property tax (1.2% annually): $350,000 × 0.012 ÷ 12 = $350/month. Homeowners insurance: $100-$200/month depending on location and coverage. PMI (if under 20% down): $150-$250/month. HOA fees: $0-$500/month depending on community. Maintenance/repairs (1% home value): $350,000 × 0.01 ÷ 12 = $290/month average (some months $0, others $3,000 for furnace). Utilities (if larger than previous residence): Extra $100-$200/month. Landscaping/snow removal: $50-$150/month. Total monthly cost: $2,752-$3,662—potentially 50-95% more than the mortgage payment alone. Budget the high end to avoid being house-poor. If you can barely afford the mortgage, you can't afford the house.
▶How do interest rates affect how much house I can afford?
Interest rates dramatically impact affordability—higher rates mean lower purchasing power for the same payment. Example: You can afford $2,500/month for P&I, with 20% down. At 3% interest: $2,500/month supports a $593,000 loan = $741,250 home purchase. At 5% interest: $2,500 supports $465,000 loan = $581,250 home (21% less). At 7% interest: $2,500 supports $376,000 loan = $470,000 home (36% less than at 3%). At 9% interest: $2,500 supports $310,000 loan = $387,500 home (48% less). When rates jumped from 3% to 7% in 2022-2023, buyers lost 35-40% of purchasing power overnight. Strategic implications: (1) Buy when you can afford it rather than trying to time rates perfectly. (2) Consider ARMs if rates are high but expected to drop. (3) Buy slightly below budget at high rates, allowing refinancing flexibility later. (4) Increase down payment to offset rate impact on monthly payments.
▶Should I get pre-qualified or pre-approved, and what's the difference?
Pre-qualification is an informal estimate based on self-reported information, taking minutes. Pre-approval is a conditional commitment after lenders verify income, assets, credit, and employment—takes 1-3 days. For example, you claim $80,000 income and get pre-qualified for $350,000. But pre-approval reveals: (1) Actual verified income is $75,000, (2) Credit score is 680 not 740 (higher rate), (3) You have $15,000 undisclosed debt, (4) Job history has gaps. Result: pre-approved for only $280,000, possibly at a higher rate. Sellers strongly prefer pre-approved buyers—it signals you're serious and financing won't fall through. In competitive markets, pre-qualification won't get your offer considered. Pre-approval advantages: (1) Know your true budget before house hunting; (2) Identify credit issues early; (3) Strengthen offers in bidding wars; (4) Close faster (underwriting partially complete). Get pre-approved from 2-3 lenders to compare rates and terms. Pre-approval typically lasts 60-90 days; renew if home search extends longer.
▶What creative strategies can help me afford more house or buy sooner?
Several strategies can increase affordability, each with trade-offs: (1) Buy with a partner/co-borrower: Combining incomes doubles purchasing power. Two people earning $50,000 each can afford significantly more than one earning $100,000 (lower DTI per person). (2) Improve credit score: Raising score from 680 to 740 can reduce rate from 7.5% to 6.5%, saving $200/month on a $300,000 loan—equivalent to affording $30,000 more home. (3) Pay off debt: Eliminating $500/month in debt payments might allow $800 more toward mortgage (due to DTI), supporting $120,000 larger loan. (4) Increase down payment: Putting 20% down instead of 5% eliminates $200-300/month PMI, allowing qualification for a larger loan. (5) House hacking: Buy duplex/triplex, live in one unit, rent others. Rental income (75% typically counted) can offset mortgage, qualifying you for more. (6) Buy in improving neighborhoods: Purchase below peak affordability in emerging areas for future appreciation. (7) Temporary buydowns: Seller pays to reduce your rate 2-3 years, lowering initial payments. (8) First-time buyer programs: FHA (3.5% down), VA (0% down for veterans), state programs with down payment assistance.
