First-Time Buyer vs Repeat Buyer: Different Rules for Each

First-time homebuyers have access to programs that significantly change the rent vs buy calculation: FHA loans (3.5% down, lower credit score requirements), conventional loans at 3% down for first-timers, state housing finance agency grants ($5K–$25K in down payment assistance), USDA and VA loans (0% down for eligible buyers), and potential $5,000 first-time homebuyer tax credit.

With 3.5% down on a $450K home ($15,750), a first-time buyer puts far less at risk than the 20% down ($90,000) conventional buyer. The tradeoff: FHA MIP (mortgage insurance premium) of 0.55%/year ($206/month) for the life of the loan, vs conventional PMI that cancels at 20% equity. Many first-timers find FHA makes buying possible years sooner than saving for 20% down.

Repeat buyers have a major advantage: existing home equity as down payment. Selling a $500K home after 5 years at 3.5% appreciation yields ~$295K in equity (after 6% selling costs on ~$592K sale price, less original $100K down and $200K remaining mortgage). That $295K can fund a 20–30% down payment on a $800K–$1M move-up home.

The key first-time buyer mistake: buying at the top of your qualification range. Lenders approve up to 43% DTI — but housing costs above 28–30% of income strain budgets and savings. Buy what's affordable, not the maximum the bank approves. The wealth-building power of homeownership is maximized when you also maintain strong savings rates.
