The Moment
You are ready to stop renting and buy a home. Maybe you have been saving for years, or maybe a life change (marriage, baby, relocation) is pushing the timeline forward.
Home buying is simultaneously the largest financial decision most people make and the one where emotions most easily override math. The goal is to make the financial decisions before you start looking at houses — because once you see the perfect kitchen, rational analysis goes out the window.
The Financial Readiness Checklist
1. Down payment: 20% is the target, 10% is the minimum. 20% avoids PMI (private mortgage insurance), which costs 0.5-1.5% of the loan annually. On a $400,000 home with 10% down ($360,000 loan), PMI adds $150-$450/month until you reach 20% equity. That is $1,800-$5,400/year in wasted money.
If 20% is not feasible, 10-15% is reasonable. Below 10%, the economics become unfavorable — higher PMI, higher rate, and less equity buffer.
2. Emergency fund: Separate from your down payment. Do not drain your emergency fund for the down payment. You need 3-6 months of expenses in savings after the purchase. New homeowners face unexpected costs immediately — repairs, appliances, furnishings.
3. Closing costs: Budget 2-5% of the purchase price. On a $400,000 home: $8,000-$20,000 in closing costs (inspection, appraisal, title insurance, origination fees, escrow). These are on top of your down payment and due at closing.
4. Affordability rule: Total housing costs under 28% of gross income. Total housing = mortgage payment + property taxes + insurance + HOA + PMI. On $100,000 gross income, that is $2,333/month maximum. This is the ceiling, not the target — below 25% gives you more flexibility.
5. Debt-to-income ratio: Under 36% total. All monthly debt payments (housing + car + student loans + credit cards) should not exceed 36% of gross income. Lenders will approve up to 43-50%, but that does not mean you should borrow that much.
The Pre-Approval Process
Get pre-approved before you shop. A pre-approval letter tells you exactly how much you can borrow and shows sellers you are serious.
Shop for the lender, not just the house. Get quotes from at least 3 lenders (bank, credit union, online lender). The rate difference between lenders on the same day can be 0.25-0.50%, which translates to tens of thousands over 30 years.
Lock your rate. Once you find a property and have an accepted offer, lock your mortgage rate immediately. Rates can change daily, and a 0.25% increase on $360,000 costs $52/month — $18,720 over 30 years.

Frequently Asked Questions
Should I use first-time buyer programs (FHA, down payment assistance)?
FHA loans allow 3.5% down with lower credit scores, but charge mortgage insurance for the life of the loan (not just until 20% equity). Down payment assistance programs vary by state and income. Both can help you buy sooner, but run the long-term cost comparison against waiting to save more. FHA is best for buyers with lower credit scores; conventional is better if your score is 720+.
Is it better to buy or continue renting?
It depends on your timeline and local market. The break-even point (where buying becomes cheaper than renting) is typically 5-7 years. If you plan to stay less than 5 years, renting is usually cheaper when you factor in closing costs, maintenance, and transaction costs. The rent-vs-buy decision is a math problem, not a lifestyle statement.
