When Should You Start Buying a Home? Six Months Before Your Lease Ends

Buying a home starts with a calendar, not a house hunt. This is the month-by-month plan for the six months before you buy, split into two halves: financial groundwork in months 6 through 4, then the active buying process in months 3 through 1. It is the first milestone of The Essential First-Time Homebuyer Roadmap, and it works the same in San Antonio, Stone Oak, or a Hill Country town like Boerne or Bulverde, with real Texas property taxes and insurance in the math.

The Countdown Has Two Halves

Phase 1, Financial Groundwork, covers months 6 to 4: income and credit checks, error disputes, balance paydowns, and the budgeting and savings that build a wall around your cash. Phase 2, The Active Buying Process, covers months 3 to 1: handing your documents to your loan officer and processor, pre-approval, touring, and the offer. Work them in order. Credit fixes need weeks to show up on scores and savings need months to grow, so skipping ahead to touring at month 4 means touring blind. The full map is in my free First-Time Homebuyer Roadmap, and this post is milestone 1 on it.

Month 6: Take Stock

The self-assessment starts about six months before your current lease expires. Pull your income numbers and your FICO scores from all three bureaus, not just the one your bank app happens to show, and count every liquid account. Then call a loan officer for a ballpark price range so you are not shopping $500,000 homes with a $350,000 budget, which happens constantly when someone skips this month. The three-bureau picture matters more than the app score, and the ballpark number costs nothing.

Month 5: Clean Up the Credit

Month 5 is credit improvement. Dispute the errors, pay down the balances, and open nothing new. Do not open a new Best Buy card because the appliance deal looks sweet; that is a fresh inquiry and a fresh account, and the only score that matters now is the one your lender pulls in month 1. Utilization is the lever that moves scores fastest, so hit the revolving cards first. New debt in month 5 has a way of showing up in month 1.

Month 4: Build the Wall Around Your Cash

Month 4 is budgeting and savings. Build the wall around your cash: separate the money you will actually use to close so it survives the months in between, and know the three buckets, the down payment, the transaction costs, and the prepaids and escrows (my cash to close guide covers them line by line). Most first-time buyers have the income and the scores; it is the savings that trip them up. And look beyond the checking account: what counts as reserves for a lender includes balances you may not have considered.

Month 3: Hand the Documents to Patrick and Patricia

Month 3 is mortgage prep. Gather the paperwork now: paystubs, W-2s or tax returns, bank statements, and ID, then hand it to Patrick the Loan Officer and Patricia the Processor, the two people who turn your raw financial life into a loan file. Get the documents in early and the hard questions get answered while you are calm and on no one's deadline, not while you are under contract with an inspection window running. Start the pre-approval process and you will get the full document checklist the same day.

Month 2: Pre-Approval and Real Texas Numbers

Month 2 is pre-approval and searching. Get the real pre-approval, not a pre-qualification chat, and start touring. This is also the month to look at real Texas property taxes and insurance quotes, not national averages. On an owner-occupied Texas home with a homestead exemption, property tax typically lands in the 1.6% to 1.8% of price range per year and homeowner's insurance runs around 0.7%, and both are baked into your monthly payment. Check the county appraisal number for the address, and if down payment help is on your radar, check Texas DPA programs now, because income limits are part of the plan.

Month 1: Make the Offer

Month 1 is when you make the offer. The pre-approval is real, the shortlist is set, and you know what the payment looks like in Bexar or Comal County. The offer is a package, not just a price. If you are reading this at month 2 instead of month 6, do not cram: do the skipped months this week and the rest on schedule. The whole sequence is laid out in my first-time homebuyer guide.

Why the Countdown Fits San Antonio

The six-month runway matches how moves actually happen here. Military families PCSing to JBSA, families moving between San Antonio area school districts ahead of a school year, and renters with summer lease renewals all do better when the calendar starts early. And because Texas property taxes and hazard insurance are real line items in your monthly payment, run the address-level numbers for Stone Oak, Alamo Ranch, or Spring Branch in month 2, not month 6.
