Financial Readiness for Buying a Home: The Complete Guide

Every guide to financial readiness for buying a home is written by a lender. Rocket Mortgage, Bankrate, Chase, NerdWallet — all want your application. That is not a criticism; they are useful resources. But a lender’s guide will always push you toward the maximum loan you can qualify for. A brokerage guide asks a different question: what loan puts you in the best financial position after you close? This guide walks through every financial readiness decision — from credit score to down payment to loan type — from the perspective of what actually serves the buyer.

What credit score do I need to buy a house?

620 is the practical minimum for most conventional loans, though Fannie Mae and Freddie Mac eliminated their firm minimum in November 2025. FHA allows 580 (3.5% down) or 500 (10% down). VA and USDA have no minimum. Critically: a 760+ score saves $74,000 in interest vs a 620 on a $400,000 mortgage over 30 years.

How much house can I afford?

The 28/36 rule: spend no more than 28% of gross monthly income on housing costs, 36% on all debt. Lenders approve up to 43–50% DTI — but that is the maximum, not your target. Being approved for more than you should borrow is one of the most common first-time buyer mistakes.

How much down payment do I need?

As little as 3% (conventional, HomeReady/Home Possible), 3.5% (FHA), or 0% (VA, USDA). 20% eliminates PMI but is not required. The median first-time buyer puts down 10%, not 20%. Over 2,000 down payment assistance programs exist nationally.

What is the difference between pre-approval and pre-qualification?

Pre-qualification: self-reported estimate, no credit check, not worth much to sellers. Pre-approval: verified income, assets, and credit — what sellers actually want to see. Pre-approval with full underwriting is the strongest offer signal short of a cash offer.
