The Affordability Formula

Lenders typically use the Debt-to-Income (DTI) ratio to determine your max loan amount. While every loan program is different, here are the general benchmarks:

Front-End Ratio

Typically 28%–31% of your gross monthly income should go toward your housing payment (PITI).

Back-End Ratio

Typically 43%–50% of your gross monthly income can go toward ALL debts (mortgage + cars + credit cards).

Factors That Impact Your Affordability

Your purchasing power isn't just a single static number. It changes dynamically based on several key financial levers that Rob Miller can help you optimize:

📈01

Interest Rates

A 1% drop in rates can increase your buying power by roughly 10%.

Even a minor shift in mortgage interest rates dramatically impacts your purchasing power and monthly structure. Rob Miller monitors daily market movements to time your rate lock perfectly.

🏛️02

Property Taxes

Madison taxes vary by area, directly shaping your borrowing limit.

Because property taxes vary across Dane County municipalities, moving just a few miles into a lower tax district can unlock tens of thousands of dollars in extra home buying power for the exact same monthly payment.

💰03

Down Payment

More upfront equity lowers loan amounts and can eliminate PMI.

Whether using savings, gift funds, or equity from a home sale, increasing your down payment reduces your monthly principal & interest while eliminating Private Mortgage Insurance (PMI) faster.

💳04

Debt Profile

Paying off a $400/mo car loan can add $50,000+ to your buying power.

Because lenders calculate your back-end DTI ratio using minimum monthly debt payments on credit reports, strategically paying off or consolidating even one monthly installment can instantly supercharge your purchase budget.
