How Much House Can You Afford in Frisco on $150K?

About $477,000. The median Frisco house is $656,300. That gap is the whole conversation.

“How much house can I afford” gets answered two ways online, and neither is useful. The first is a multiple of income - three times, four times - which ignores rates, taxes, and your existing debt. The second is whatever a lender will approve, which is a ceiling on their risk, not a budget for your life.

Here is the actual arithmetic, on Frisco's real tax rate at July 2026 rates, with every assumption stated so you can argue with any of them.

The Short Answer

Household income of $150,000 is $12,500 a month gross. Assume $500 a month in other debt payments - a car, a student loan - and 20% down at a 6.55% 30-year fixed.

Note how much of that $3,500 never reaches the house. Tax and insurance take $1,026 a month - just under 30% of the entire housing budget - before a dollar goes to principal or interest. That is the Texas trade, and it is why national affordability rules of thumb consistently overstate what you can buy here.

The Two Limits, and Why They Disagree

Lenders apply two ratios, and almost nobody explains that they produce wildly different answers.

The front-end ratio caps housing at 28% of gross income: $3,500 a month, which is the figure above. The back-end ratio caps all debt at 43%: $5,375 a month, less your $500 car payment, leaving $4,875 for housing.

Run the same math at $4,875 and the supported price is about $730,000.

So the honest answer to “what can I afford on $150,000 in Frisco” is a range from $477,000 to $730,000, and which end you land on depends on which rule your lender applies. Many will work to the back-end number. That does not make it wise - it means a quarter of a million dollars of the answer is a judgment call about how much of your income should go to a house, and the lender is not the right person to make it.

The affordability calculator runs both limits and shows you which one is binding for your situation, along with what your credit score does to the answer through mortgage insurance.

Where the Texas Money Goes

Frisco's effective combined property tax rate is about 1.68%. That is genuinely low for this metro, and the reason is structural rather than political: Collin County funds no hospital district. Its cities - Frisco at 1.68%, Plano at 1.71%, McKinney at 1.75% - all sit well below Dallas County peers like Garland at 2.39% and Rowlett at 2.51%.

This is worth internalizing because the folk wisdom has it backwards. People assume the newer exurban communities are the high-tax ones. On the base rate they are not.

The real exposure is what the base rate excludes. MUD, PID, and MMD levies are parcel-specificand do not appear in any city-level figure. A home inside one can clear 2.7% all-in, which on a $477,000 purchase is roughly $400 a month of additional tax - about $54,000 of purchasing power. In Frisco's newer sections this is common enough that you should assume it applies until someone shows you otherwise.

Insurance is the other line people underestimate. DFW runs near 0.9% of value per year, repriced hard on hail and severe storm losses, and it is not a number that trends down.

The Frisco Gap

Frisco's median single-family value is $656,300 - the highest of any city covered on this site except Prosper. The conservative affordability figure on $150,000 is $477,000. There is a $179,000 gap between them.

What that means practically: on this income you buy in Frisco, but you buy in its lower tiers - townhomes, older sections, smaller lots. You do not buy the median detached house in a newer master-planned community, and no amount of shopping changes that.

Which is why the most useful thing to do with this number is often to widen the map:

Watch Richardson in that table. The lowest price and the highest tax rate, which partly cancel - a reminder that comparing cities on sticker price alone is close to meaningless here. Compare the all-in monthly cost instead.

The Four Levers That Actually Move It

1. Paying off consumer debt. Under the back-end limit, every $100 of monthly debt you clear returns roughly $13,500 of purchasing power. That $500 car payment is costing you about $67,000 of house.
2. Your credit score. Below 20% down, mortgage insurance spans roughly 0.19% to 1.86% of the loan annually depending on score and loan-to-value. Moving from the middle of that card to the top of it is worth tens of thousands in price - more than most people gain by shopping lenders.
3. The down payment - but less than you think. Cash down mostly converts to equity rather than buying power, because the payment limit still binds. It matters most at the 20% threshold, where PMI disappears entirely.
4. The address, not the city. Two Frisco houses at the same price can differ by $400 a month on MUD or PID exposure alone. This is the lever nobody looks at and the one most likely to change your answer.

Approved For vs. Should Spend

A pre-approval is calculated on gross income. Yours is not gross. Federal tax, retirement contributions, health insurance, and childcare all come out before you ever see the money, and none of them appear in a debt-to-income ratio.

A household at the $730,000 end of that range is committing roughly $4,875 a month to housing out of maybe $9,000 of actual take-home. That is survivable right up until the year it isn't - and North Texas prices are currently down about 5% year over year, which means the escape hatch of selling into an appreciating market is not currently open.

The number worth finding is not the maximum. It is the payment that still lets you fund retirement, keep six months of reserves, and absorb a $14,000 HVAC without a credit card. For most households on $150,000 that figure is nearer the front-end limit than the back-end one, which is exactly why the conservative answer leads this post.

Run your own inputs first. Then, if the Frisco gap is the problem, the conversation worth having is about which neighboring city gets you the house you actually pictured.

One more variable this page holds fixed but you should not. Everything above assumes a conventional loan, and the loan type moves the answer more than most buyers expect - the FHA limit in this metro is $563,500, which no longer reaches the Frisco median at all, and FHA mortgage insurance at 3.5% down never comes off the way conventional PMI does. If the down payment is what is binding, read how FHA, conventional, and VA actually compare in Texas before you settle on one.
