Home Buying Rules of Thumb


With warm weather just around the corner, home buying season is starting, and it’s the perfect time to discuss current mortgage rates, where they might be headed, and what influences them.

As of this recording, mortgage rates have dropped below 6% for the first time in years. But how are rates determined?

Contrary to popular belief, mortgage rates aren’t set by the Federal Reserve or political decisions, although both influence the economic environment. Rates are largely driven by the bond market, particularly the 10-year Treasury yield, which reflects long-term inflation expectations.

Bond markets dislike uncertainty, and with ongoing questions around trade, tariffs, jobs, economic growth, and government policy, rates have been volatile. When certainty returns, rates tend to stabilize and may decrease, improving home affordability.

What You Can Control:

While we can’t control market-driven rates, we can control our financial decisions:

How much home to buy
How much to put down


Here are some practical rules of thumb:

Payment Guidelines: Keep your total housing payment under 28% of your gross income, and ideally under 25% of your total take-home pay.


Home Price: Your home price should generally be around 3 times your gross income.


Down Payment: While the conventional wisdom suggests 20% down, this isn’t always optimal. Paying 20% upfront often means tying up cash, losing liquidity, and potentially paying less strategically toward debt repayment or investments.


Many clients find that putting less than 20% down allows them to:

Maintain liquidity for emergency savings
Pay down high-interest debt (student loans, credit cards, medical debt)
Invest strategically for long-term growth
Retain flexibility in monthly cash flow
As your home appreciates, PMI (Private Mortgage Insurance) can often be removed without refinancing, mitigating the cost of a lower down payment.

Real-World Example:

I recently helped a family analyze their finances for purchasing a larger home to accommodate an expanding family. By modeling short-term and long-term impacts, we determined a lower down payment and slightly higher mortgage payment allowed them to:

Pay off debt efficiently
Maintain emergency savings
Continue investing for retirement and college funds
Keep cash flow comfortable for day-to-day life
The result? Confidence and clarity about exactly how much home to buy and how much to put down, even in an unpredictable market.
