Mortgage Money Myths: How Much House Can I Afford Is Not the Same as How Much Can I Qualify For
Helping homebuyers and homeowners make smarter financial decisions, one mortgage question at a time.
“Doug, how much house can I afford?”
That’s one of the most common questions I hear from homebuyers.
But that’s actually not quite the question I want you to ask me.
As your lender, I can determine how much mortgage you may qualify for.
What I really want to help you determine is how much house you can comfortably afford.
Those can be two very different numbers.
I don’t live with you. I don’t know how often you eat out, how much you spend on Amazon, whether you love expensive vacations, have an expensive hobby, or if Las Vegas considers you a preferred customer.
And frankly, that’s not my money to spend.
My job is to determine your maximum qualification, show you what real monthly payments could look like at different price points, and give you the information you need to decide what payment fits your life.
I’m not here to make you house poor.
Let’s discuss how to find the right number.
Qualification Gives Us the Ceiling
There is value in knowing the maximum amount you qualify for.
It establishes the boundaries of your home search.
Maybe you qualify for a $600,000 purchase but originally planned to stay around $500,000.
Great.
That doesn’t mean you should immediately start shopping for $600,000 homes.
It means we understand your options.
Now we can compare them.
What would $500,000 look like?
What about $550,000?
And what would the payment actually look like at $600,000?
Knowing your maximum gives you flexibility if the right home comes along.
It does not mean you have to spend it.
Start With the Payment, Not Just the Purchase Price
Homebuyers naturally think in terms of purchase price.
“I don’t want to spend more than $500,000.”
That’s a perfectly reasonable starting point, but it doesn’t tell us enough.
I’d rather ask:
What total monthly housing payment would allow you to comfortably live the life you want?
Maybe your number is $2,500.
Maybe it’s $3,500.
Maybe it’s considerably higher.
There isn’t a universally correct answer.
It’s your answer.
Once we know the payment you’re comfortable with and the maximum amount you qualify for, we can work backward to determine an appropriate purchase range.
Sometimes buyers are surprised by what they discover.
Maybe you tell me you absolutely don’t want to spend more than $3,000 per month.
Then we run the numbers on the house you really love and the estimated payment comes to $3,175.
Is that additional $175 worth it?
Maybe.
Maybe not.
That’s not my decision. It’s yours.
My responsibility is to make sure you understand the numbers before you make it.
The Price of the Home Does Not Tell You the Payment
This is one of the most important concepts for homebuyers to understand.
Two homes with exactly the same purchase price can have very different monthly payments.
Your total housing expense may include:
- Principal and interest
- Property taxes
- Homeowners insurance
- Mortgage insurance, when applicable
- Homeowners association dues
- Potentially other property-specific expenses
That’s why shopping strictly by purchase price can be misleading.
Consider a Scottsdale Condo
Imagine you find a condo in Scottsdale for $450,000.
It’s beautiful. Great location. And it’s comfortably below the $500,000 maximum purchase price you had in mind.
Then we look at the HOA.
$1,000 per month.
Suddenly, that $450,000 condo could have a substantially higher monthly housing expense than a $500,000 single-family home with a $100 HOA.
The less expensive property isn’t necessarily the more affordable property.
This is one reason single-family residences can sometimes provide better monthly economics than condos or townhomes, even when the purchase price is higher.
But we shouldn’t automatically assume an HOA is wasted money either.
A condo HOA might include exterior maintenance, roof coverage, landscaping, water, community amenities, or other services you would otherwise pay for separately.
The important thing is understanding:
What am I paying, and what am I receiving for it?
Your Preapproval Is Not a Blank Check
Here’s something homebuyers don’t always realize.
Your maximum qualification can change depending on the property you choose.
Let’s say you’re preapproved up to $550,000 based on reasonable estimates for taxes, insurance and HOA expenses.
A $550,000 home with a $75 monthly HOA may work perfectly.
A $550,000 condo with a $900 HOA may not.
The purchase price didn’t change.
The monthly obligation did.
The same thing can happen with property taxes and homeowners insurance.
That’s why your lender should review the actual property before you assume that a home within your approved price range automatically fits your qualification.
This is also where my advice gets very simple:
Send me the property and I’ll run the numbers.
Before you fall in love with the home, let’s find out what owning it may actually cost.
Property Taxes Matter
Property taxes can vary significantly from one property to another.
A buyer might compare two similarly priced homes and discover that one carries a noticeably higher tax obligation.
That difference becomes part of the monthly housing payment.
New construction, different communities, special taxing districts, property location and other factors can all affect property taxes.
The purchase price is only part of the equation.
Homeowners Insurance Matters Too
Insurance deserves more attention in today’s homebuying conversation.
During an initial prequalification, we may use an estimate for homeowners insurance.
Once you’ve identified a property, obtaining an actual insurance quote can give us a much clearer picture.
Property type, location, age, roof condition, coverage selections and other factors may affect the actual premium.
A house that looks affordable based on purchase price can look different once the true insurance cost is included.
Again:
Know the entire payment.
Don’t Choose a Loan Program Based on One Number
Another mistake buyers make is comparing mortgage programs based only on the interest rate or down payment.
The interest rate matters.
But so does everything else.
Different mortgage programs can produce very different financial outcomes.
Let’s look at a few examples.
Conventional Financing and Mortgage Insurance
One of the biggest homebuying myths is that you need 20% down to purchase a home.
You don’t.
Depending on eligibility and the loan program, first-time homebuyers may have conventional financing options requiring as little as 3% down.
Rocket Mortgage also offers certain programs that may allow eligible buyers to purchase with as little as 1% down.
Twenty percent is not the admission price for homeownership.
When putting less than 20% down on many conventional mortgages, however, private mortgage insurance may apply.
PMI isn’t necessarily one universal price.
Your credit profile, down payment, loan characteristics and other risk factors can influence its cost.
And PMI isn’t automatically a bad thing.
Imagine you have $70,000 available.
You could put nearly all of it toward your home to reduce your mortgage and potentially eliminate mortgage insurance.
But should you?
What if putting less down allowed you to keep $25,000 or $30,000 in emergency reserves?
What if using $25,000 to eliminate a $700 monthly car payment puts you in a stronger overall financial position than putting that same $25,000 toward the house?
Those are the conversations worth having.
Twenty percent down isn’t necessarily the goal. Finding the right financial structure is.
FHA Financing and Mortgage Insurance
FHA financing can be another excellent option for eligible borrowers.
FHA loans generally include both an upfront mortgage insurance premium, commonly called UFMIP, and an annual mortgage insurance premium, commonly called MIP, that is typically collected as part of the monthly mortgage payment.
The upfront premium can generally be financed into the mortgage rather than paid entirely in cash at closing, although doing so increases the loan balance.
Some buyers hear “mortgage insurance” and immediately assume FHA is the worse option.
Not necessarily.
Depending on credit, available down payment, interest rates, qualification and other factors, FHA financing can sometimes produce a more attractive overall structure than conventional financing.
That’s why I don’t want to decide that FHA or conventional is better based solely on the name of the program.
Let’s run both and compare the numbers.
VA Financing and the VA Funding Fee
For eligible veterans, active-duty service members and certain surviving spouses, VA financing can provide tremendous purchasing power.
Eligible borrowers may be able to purchase with no down payment.
VA loans also do not require monthly private mortgage insurance.
Depending on the borrower’s circumstances, however, a VA funding fee may apply.
The funding fee can generally be financed into the mortgage, and the amount can vary depending on the transaction, down payment and other eligibility factors.
Many veterans are exempt from paying the VA funding fee.
For example, veterans receiving qualifying VA compensation for a service-connected disability may be exempt. This can include veterans with a VA disability rating of 10% or greater who are receiving qualifying disability compensation.
This is why I want to review a veteran’s Certificate of Eligibility and complete VA eligibility before simply comparing loan programs.
For one borrower, conventional financing may make the most sense.
For another, FHA may provide the better structure.
For an eligible veteran, VA financing can completely change the equation, particularly when there is no monthly PMI and the veteran is exempt from the VA funding fee.
Don’t choose the loan program first and then try to make your finances fit it.
Let’s look at your finances first and determine which program fits you.
How Much Should You Put Down?
Another common question:
“Doug, how much should I put down?”
My answer?
Let’s run the numbers.
Putting more money down generally lowers your loan amount and monthly principal and interest payment.
It can also affect mortgage insurance and loan pricing.
But every dollar you put into the house is a dollar that is no longer sitting in your bank account.
Depending on the interest rate and term, an additional $1,000 down may only reduce principal and interest by several dollars per month.
That doesn’t mean putting more money down is a bad idea.
It means we need to compare it against your other choices.
Could some of that money eliminate high-interest credit card debt?
Could it eliminate a large car payment?
Would keeping additional emergency reserves make you more financially comfortable?
Could seller concessions cover some of your closing costs instead?
There isn’t one correct answer.
Cash to Close Is More Than Your Down Payment
If you have $50,000 available for your purchase, don’t automatically assume:
$50,000 available equals $50,000 down payment.
You may also need money for:
- Closing costs
- Prepaid taxes and insurance
- Moving expenses
- Furniture
- Repairs
- Appliances
- Emergency reserves
And then there’s the inevitable expense that seems to appear approximately five minutes after you become a homeowner.
Homes have a wonderful sense of timing.
Keeping some cash available after closing can be just as important as reducing your mortgage payment.
Don’t Forget About the Rest of Your Life
Mortgage qualification looks at documented income, debts, credit and applicable underwriting guidelines.
But underwriting doesn’t live your life.
You do.
Your budget might also include:
- Childcare
- Groceries
- Utilities
- Travel
- Retirement contributions
- College savings
- Helping family members
- Hobbies
- Entertainment
- Future vehicle purchases
- Medical expenses
- Home maintenance
- Dozens of other things that matter to you
That’s why I can’t simply look at your approval and tell you:
“You qualify for $600,000, so go spend $600,000.”
I don’t live with you.
I don’t manage your checking account.
And I shouldn’t spend your money.
I Am Not Here to Make You House Poor
Being house poor doesn’t necessarily mean you can’t make the mortgage payment.
You may make it every month without ever being late.
But if the payment means you can’t save for retirement, take a vacation, go out to dinner, build emergency savings, enjoy your hobbies or live the life you worked hard to create, we should at least ask whether you’re buying too much house.
At the same time, I don’t want buyers automatically choosing the cheapest house either.
Buying too little house and needing to move again in two years can also be expensive.
The goal is balance.
Buy enough house to reasonably support where you expect your life to be over the next several years without sacrificing everything else you’re working toward financially.
Stress Test the Payment
Here’s another question worth asking before closing:
If life suddenly cost me another $500 per month, would I still be comfortable with this mortgage?
Cars break.
Air conditioners break.
Insurance premiums change.
Children need things.
Life happens.
The goal isn’t to scare yourself out of buying a home.
It’s to make sure your housing payment still works when life isn’t perfect.
Sometimes Your Comfort Level Changes Once You See the Numbers
This is why I like showing buyers multiple scenarios.
Maybe you’re approved for $600,000 but initially tell me you want to stay under $500,000.
Let’s look at $500,000.
Then $550,000.
Then $600,000.
Let’s calculate estimated payments.
Let’s look at cash to close.
Let’s compare loan programs.
Let’s evaluate different down payments.
Let’s look at mortgage insurance.
Let’s account for the HOA.
Let’s see what happens if you pay off another debt.
Now you’re no longer guessing.
You’re making an informed decision.
Maybe you discover that you’re perfectly comfortable spending another $150 or $200 per month to get the house you really want.
Maybe you look at the numbers and decide:
“Nope. I’m staying exactly where I started.”
Both answers are perfectly fine.
It’s your money.
Your Realtor and Lender Should Work Together
Your Realtor helps you understand the property, neighborhood, market, comparable sales and negotiating strategy.
Your lender helps you understand the financing.
Those conversations should happen together.
If you find a home you’re considering, send it to me.
We can look at:
- Actual property taxes
- HOA
- Estimated insurance
- Financing options
- Down payment
- Potential seller concessions
- Estimated payment
- Cash needed to close
Then you and your Realtor can make an offer with a much clearer understanding of what the property actually means financially.
So, How Much House Can You Actually Afford?
There isn’t a universal formula.
And there shouldn’t be.
I can tell you the maximum mortgage you qualify for.
I can show you different purchase prices.
I can calculate estimated monthly payments.
I can compare conventional, FHA, VA and other eligible financing options.
I can show you what happens when you put more or less money down.
I can help you understand how taxes, insurance, mortgage insurance and HOA dues affect your payment.
But I can’t tell you how much of your life you should sacrifice to make that payment.
That’s your decision.
My job is to give you the numbers, explain the tradeoffs and help you make an informed choice.
Because:
How much house you can afford isn’t necessarily how much house you can qualify for.
Send Me the Property and I’ll Run the Numbers
If you’re shopping for a home and find one you’re interested in, send me the property and I’ll run the numbers.
You don’t need to guess what a $450,000, $500,000 or $600,000 home might cost you each month.
I’ll help you look at the entire picture, including:
- Purchase price
- Estimated principal and interest
- Property taxes
- Homeowners insurance
- HOA dues
- Mortgage insurance, if applicable
- Different down-payment options
- Available loan programs
- Estimated cash needed to close
- How those numbers fit within both your qualification and the payment you’re comfortable with
Sometimes a property that looks expensive based on purchase price can actually fit your budget.
Other times, a property that appears affordable can become much more expensive once we discover a large HOA, higher taxes, insurance costs or other expenses.
That’s why I want to run the numbers before you fall in love with the house.
Once you understand the payment, you decide whether the home makes sense for you.
Not me.
Not a computer.
Not an arbitrary preapproval amount.
You.
Because I don’t live with you, I don’t manage your checking account, and I shouldn’t be spending your money.
I’m not here to make you house poor.
I’m here to give you the numbers, explain your options and help you determine the best way forward.
Found a House You Like?
Send me the property and I’ll run the numbers.
