Buying a home — clearly, with the math exposed.

A common rule is 20% down plus 3% closing costs plus 6 months of full housing cost in liquid reserves. That's roughly 30% of the home price total. Buyers using FHA or 5% conventional can buy with much less, but the comfort buffer matters as much as the down payment — see the affordability calculator and the House Poor Risk Score.

The honest answer depends on three things: how long you'll stay, what rates and prices do over that period, and what rent costs in your market. The Buy Now vs Wait calculator runs both scenarios under your assumptions; the Rent vs Buy calculator handles the longer comparison.

Treating the lender's pre-approval as a target rather than a ceiling. Lenders approve up to 43–50% back-end DTI; sustainable household budgets typically run at 28–36%. The gap between what you can borrow and what you can comfortably afford is often $100K+ in home price.

Yes. A pre-approval letter is required by most sellers' agents to take an offer seriously, and the underwriting process surfaces issues you'd rather find before falling in love with a home. Don't take the pre-approval amount as your shopping budget — that's a separate decision.
