Buyer field guide · first home
A practical route from setting a real budget to choosing financing, documenting an offer, and leaving the notario with a registered ownership record.
Open the guideThe method / applied to buying
A first purchase becomes manageable when each unknown is turned into a named output.
You do not need to understand the entire transaction on day one. You do need to know what you can spend, who is advising you, what each document does, and what must be verified before money changes hands.
Operating stack
Run these workstreams together. They converge when you are ready to make a written offer.
Set a comfortable monthly payment, then reserve separately for appraisal, taxes, notario and registration fees, maintenance, insurance, and the move.
↗Check eligibility and compare a bank mortgage, Infonavit for eligible private-sector workers, Fovissste for eligible public-sector workers, or a co-financing structure.
↗Confirm whom the agent represents, which buyer-side services are included, how compensation works, and how either party can end the relationship.
↗Prepare identity, CURP/RFC, income and bank records, and financing approval; then organize the appraisal, title review, purchase contract, payment evidence, and deed.

Buyer archive
A home is only one part of the purchase. These are the records that turn interest into a transaction you can explain and verify.
Systems
Budget, representation, written terms, and verification move as one operating loop. Each leaves evidence behind.
Study the loopTwo common routes
Financing changes the sequence and the conditions in the offer. It does not remove the need for representation, document review, or a clear closing record.
Financed purchase
Ask the lender what you qualify for, what cash must remain available, and which appraisal or property conditions could affect approval before you commit.
Self-funded purchase
Document where the funds will come from, how they will move, who may receive them, and how every instruction will be independently verified.
Field notes
A lender’s early estimate of borrowing capacity—not a final promise to lend.
Ask what still must be verified and when the estimate expires.A reservation payment that may temporarily remove a property from active marketing.
Put the amount, holder, refund rules, and deadline in writing before paying.The purchase agreement that records price, conditions, dates, obligations, and consequences of default.
Have the exact draft reviewed before signing.A formal appraisal used to support value and, depending on the transaction, financing or tax calculations.
Confirm who orders it, who pays, and how the result affects the deal.The notario is a specially authorized legal professional who formalizes qualifying transfers; the escritura is the formal deed instrument.
Ask how title, liens, taxes, identity, and registration will be verified.Operating loop
Open each control point. The exact forms vary, but a well-run purchase should leave you with the named output before you move on.
Choose the monthly payment and cash ceiling that still leave room for closing costs, maintenance, insurance, emergencies, and moving.
Readiness brief
Use this as a planning check, not a legal determination. Select the controls you have already defined and take the unfinished list into your next professional conversation.

Requirements, fees, taxes, and transaction steps vary. Confirm the numbers with your lender and have the exact property and documents reviewed by qualified professionals before signing or transferring funds.
