Your debt-to-income ratio (DTI) is the most critical factor when determining how much home you can afford. This ratio, which most financial experts say should ideally be 36% or lower, represents the portion of your gross monthly income that goes toward paying debts.
To calculate your DTI, sum up your monthly debt payments and divide this total by your gross monthly income. For example, with monthly debts of $3,600 and a gross income of $10,000, your DTI is 36%.
The 28/36 rule is a standard benchmark in home affordability. It suggests that your monthly mortgage payment shouldn’t exceed 28% of your gross income, and your total monthly debts (including your mortgage) shouldn’t surpass 36% of your income.
However, affordability is not just about DTI ratios.

The Many Factors Of Home Affordability
Home affordability encompasses your overall financial health. This includes your income, down payment, loan term, interest rates, and credit score. Higher down payments can increase the mortgage amount you qualify for, while longer loan terms offer lower payments at the cost of more interest over time. Additionally, a better credit score can secure more favorable interest rates, significantly affecting long-term affordability.
Don’t forget to factor in other homeownership costs like property taxes, insurance, potential HOA fees, and closing costs, which typically range from 2% to 5% of the home’s price.

Other Considerations For Determining Your Housing Budget
Thus far, we’ve looked at standard industry guidance on calculating a budget for buying a home. But there are some strong considerations that I have not seen mentioned elsewhere. These “other considerations” should be scrutinized by you and your real estate agent before you go looking at homes.
#1 – Set a budget before you go looking at homes
If you start exploring homes for sale before establishing your budget, it typically leads to unfavorable outcomes. In fact, one of three likely scenarios will unfold, none of which are beneficial:
- You love the home but discover it is not one you can afford. After establishing a budget, you’ll have to look at homes that will not compare favorably to the higher-valued one you went to see before qualifying your budget.
- You love the home, make an offer, and find that the seller will not accept an offer from an “unqualified buyer.” You then go get qualified but later find that the home is already under contract with another buyer.
- You do not like the home, and you’ve wasted time.
#2 – Understand current market conditions
Reviewing my articles and videos from 2020 and 2021, when interest rates hovered below 3%, you’ll find I advised buying as much home as feasible. This meant stretching to what the bank would allow and what you felt was sustainable. My guidance wasn’t to buy a home that met immediate needs but rather to aim for the next one, the home you’d aspire to after the current one. For those already in their ‘next home,’ I recommended refinancing to capitalize on the exceptionally low rates of that time. It was a unique opportunity that savvy buyers leveraged to their advantage.
Mortgage interest rates were at all-time historical lows, and I knew they would not last. Additionally, the supply of homes was at a historical low, so I knew home values would rise faster than ever. The combination of rising prices and historically low rates suggested a future with much higher home prices and much higher mortgage interest rates.
Some YouTube viewers criticized me, claiming I was merely acting as a salesman by urging people to buy now. This perspective is misguided, as I’ve since received numerous appreciative comments on these videos and articles. One particular comment from a viewer named Edward stood out and motivated today’s post. Here’s a simplified account of Edward’s experience.
YouTube Viewer Case Study
In December 2020, Edward bought a $300K home, financing $285K at a 2.8% interest rate with a $15K down payment and $12K in closing costs. His initial outlay was $27K with a monthly mortgage payment (principal and interest) of $1,171.
While I’m unsure of the specific market Edward was in, considering the US housing market’s average 40% gain since his purchase, here’s how his situation looks now:
His $300K home is now valued at around $420K. This $120K increase in equity over 36 months translates to a monthly gain of $3,333, more than double his mortgage payment. Moreover, he’s upgraded to living conditions he couldn’t afford today. If he were to purchase the same home now, his monthly payment would skyrocket by 123% to $2,609.
Edward’s gratitude for the advice received brings me to my conclusion about “understanding current market conditions.” Finding a trustworthy real estate agent and heeding their advice is crucial. Choose someone who actively studies the market and prioritizes your needs.
#3 – Look For Homes With Assumable Loans
Did you know that many of the home loans put in place from purchases and refinances since early in 2009 have assumable loans with interest rates below 5%? It is easier to qualify to assume one of these loans than it is to get a new one today (because they have lower rates).
Unfortunately, most real estate agents today do not understand loan assumptions. How do I know this as a fact? When I open the Tallahassee MLS, do a home search of available properties, and specify I want homes with assumable loans, only 2 show up out of nearly 850 homes (less than 1/2 of 1% of listed homes). I suspect that more than one-third of all homes for sale today have assumable loans!
The lack of recognition by real estate agents wastes most assumable loans. The homes get sold to unknowing buyers who obtain loans for longer terms, higher interest rates, and much higher monthly payments.
The older the loan, the harder it will be to assume (as much of the loan has been paid down, so you’ll need to be able to pay for the difference between the loan amount and the sales price. But there are methods available there, too!
When you are interviewing agents for the job of helping you buy your next home, ask them to talk you through their experience with assumable loans. One recent buyer I know of purchased a home with an assumable loan with a 3% rate (just as the mortgage market was hitting 8%). The family buying the home will save about $900K over the life of the loan!
