5How much house can I afford?
This calculator demonstrates the common 28/36 rule: typically 28% of gross income for housing, 36% for total debt. The calculation shows: Available Housing Budget = min(Income × 0.28, (Income × 0.36) - Current Debts). This educational example finds the highest home price where Total Monthly Payment ≤ Available Budget.
6What's included in my total monthly housing payment?
Your total payment includes: Principal & Interest (loan payment), Property Taxes, Homeowners Insurance, PMI (if down payment < 20%), and HOA fees. This is often called PITI+HOA. For example: $1,500 P&I + $400 taxes + $150 insurance + $100 PMI + $200 HOA = $2,350 total monthly payment.
7Do I really need 20% down payment?
Many loan programs allow as little as 3% down (conventional) or 3.5% (FHA). A 20% down payment eliminates PMI insurance, reduces monthly payments, and may make offers more competitive. With less than 20% down, PMI is typically required until you reach 20% equity.
8What is PMI and when can I remove it?
PMI (Private Mortgage Insurance) protects the lender if you default. It costs 0.3-1.5% of loan amount annually. You can remove PMI when you reach 20% equity through: payments over time, home value appreciation, or home improvements. Some loans auto-cancel PMI at 22% equity.
9How does my credit score affect my mortgage rate?
Credit scores significantly impact rates: 760+ gets best rates, 700-759 adds ~0.25%, 640-699 adds ~0.75%, below 640 adds 1.5%+. On a $300,000 loan, poor credit costs an extra $270/month. Improve your score before applying to save thousands.
10What's the difference between 15-year and 30-year mortgages?
30-year: Lower monthly payments, more flexibility, but more total interest. 15-year: Higher monthly payments, less total interest, faster equity building. Example: $300K loan at 6.5% - 30yr: $1,896/month, $382K total interest; 15yr: $2,613/month, $170K total interest.
11What closing costs should I expect?
Closing costs typically run 2-5% of home price and include: loan origination fees, appraisal, inspection, title insurance, attorney fees, and prepaid taxes/insurance. On a $400K home, expect $8K-$20K in closing costs. Some can be negotiated with the seller.
12How much should I save beyond the down payment?
Save for: Down payment + Closing costs (2-5% of price) + Moving expenses + Emergency fund (3-6 months of new housing payment) + Immediate repairs/furnishing. For a $400K home, budget $50K-$80K total cash needed.
