Buying Your First Luxury Home in North Texas with Confidence

Last Updated: October 31, 2026

What does it cost to move from a $400K home to a $700K+ home in the Alliance Corridor?

At the 30-year fixed rate Freddie Mac reported on October 29, 2026 (7.24%), a $700,000 home with 20% down carries principal and interest of about $3,800 a month. Add property taxes (Alliance Corridor communities run about 2.43% to 2.72%), insurance, and HOA dues, and the payment lands around $5,700 to $5,900 a month before utilities and upkeep. That’s about $1,500 more a month than a $500,000 home on the same terms. Your lender decides what you qualify for. This guide shows the math and the trade-offs. We’re Realtors, not financial advisors, so check your numbers with a lender.

You’ve built equity in your starter home. Your family is growing, and you’re ready for more space, a different school district, or a community with real amenities. But the jump from $400,000 to $700,000 can feel big, and the numbers have changed.

Every week we work with families making this move in the Alliance Corridor between Dallas and Fort Worth. This guide gives you the real math, the costs people miss, and the questions to ask, without promising outcomes nobody can promise.

Section 1: The Real Numbers

What a $700K Purchase Costs Per Month

The figures below are illustrations, not quotes. They assume a $700,000 purchase price, 20% down ($140,000), a 7.25% 30-year fixed rate (close to Freddie Mac’s October 29, 2026 average of 7.24%), principal and interest of about $3,820 a month, and each community’s actual HOA dues and total tax rate applied to the purchase price before exemptions. Insurance is an example of $300 a month, so get a real quote.

Notes:

• Pecan Square’s HOA starts at $2,260 a year for most lot types and goes higher for others (up to $3,355 for rear-entry 70' lots, and $7,060 for townhomes).
• Treeline’s HOA includes front yard maintenance.
• Landmark’s tax rate includes a 0.77% MMD, and Furst Ranch’s includes a $1.20 MUD.
• Harvest’s taxes vary by lot and school district, so it isn’t in the table.

What this means: the four communities are within about $140 a month of each other in this example, so the choice usually comes down to schools, lot, builder, and timeline rather than carrying costs. Compared with a $500,000 home on the same terms (about $4,180 a month in Pecan Square), a $700,000 home adds roughly $1,550 a month. Utilities, maintenance, and landscaping are on top.

If you put 10% down: the loan is $630,000, and principal and interest rise to about $4,300, roughly $480 a month more, plus mortgage insurance (PMI), which depends on your credit and loan terms. Ask your lender for a quote.

A quick sense of income: lenders look at housing costs and total debt as shares of your gross income, and the limits depend on your loan type. As an illustration, a housing cost of about $5,730 to $5,870 a month at a 28% housing ratio implies roughly $245,000 to $252,000 a year in gross income, and at 31% roughly $222,000 to $227,000. Some loan programs allow higher ratios, and your actual debts matter. Your lender gives your real numbers.

Rates Right Now

Mortgage rates rose for seven straight weeks through early October, and Freddie Mac’s 30-year average was 7.40% on October 8 and 15, then 7.24% on October 29. A year earlier it was about 6.2%. Nobody can predict where rates go from here.

Waiting versus buying now is a real trade-off with no guaranteed winner:

• If you wait, rates might fall, but prices and builder incentives might also change, and you can’t know in which direction.
• If you buy and rates fall later, you may be able to refinance, but refinancing costs money and isn’t guaranteed to be possible or worthwhile.

Talk with a lender about how each path looks with your numbers.

What You’ve Built in Your Current Home

Equity is roughly your home’s market value minus your mortgage payoff and the costs of selling. Start with an estimate of value from recent comparable sales, subtract your payoff, and subtract selling costs (commission, title, and prep). We can pull your comparables in a 30-minute consultation.

Section 2: What Changes at $700K and Up

What You Typically Get

Home sizes, finishes, and lots vary by community and builder, but at $700K and up in the Alliance Corridor you’re generally looking at more square footage, larger lots, upgraded finishes, flex spaces like offices and game rooms, and communities with fuller amenity packages. Use our community guides for specifics.

Communities Compared

Prices, fees, and tax rates change. Verify them before you budget. See our guides to Pecan Square, Harvest, Treeline, Furst Ranch, Landmark, and large lots.

Schools

Argyle ISD, Northwest ISD, and Denton ISD each serve different communities, and zoning is by address. Hillwood describes Argyle ISD as ranked in the top 1% of Texas districts. Confirm zoning with the district, visit campuses, and look at the data that matters to your family. We help families compare, but no district is right for everyone.

Costs People Miss

• Property taxes: your second-largest housing cost, and they change as appraised values change. Homestead exemptions can reduce them. Ask the county.
• Insurance: quotes vary widely. Get one before you make an offer.
• HOA dues: from about $133 a month at Landmark to higher at Pecan Square, depending on lot type. Compare what’s included.
• Special districts: ask for the MUD, PID, or other district disclosure for any home you’re considering.
• Utilities: a larger home generally costs more to heat and cool, though newer construction can help. Ask the builder or previous owner for typical bills.
• Upkeep: landscaping, pest control, HVAC maintenance, and pools (if you add one) all add up.
• Furnishing: larger rooms and windows can mean more furniture and window treatments than you expect. Many buyers spread this out over a year or two.

Section 3: Timing the Sale and the Purchase

How you coordinate selling and buying matters as much as price. The common approaches:

1. Sell first, then buy. Cleanest financially, with cash in hand and no contingency. The risk is needing temporary housing, which you can sometimes reduce with a rent-back.
2. Contingent offer. Your offer depends on selling your current home. Sellers and some builders may resist, depending on the market.
3. Bridge loan or carrying two mortgages. Gives flexibility but is more expensive and requires strong income, credit, and reserves. Ask a lender about the real cost.
4. Buy new construction. An inventory home can close faster, and a to-be-built home has a longer timeline, so you can plan listing your current home around the completion date. Build timelines can slip.

Seasonality: spring has historically been a busy season for sellers in our market, and winter slower, but recent years haven’t always followed the pattern. We’ll look at current data with you.

Section 4: Financing a Higher-Priced Home

This is general information, not financial advice. Your lender gives you real terms.

• Conventional (conforming) loans: the 2026 baseline conforming limit for a one-unit home is $832,750 in most counties. Loans above the limit are generally jumbo loans, which can have different qualification standards, down payment requirements, and rates.
• Down payment: conventional loans allow less than 20% down, usually with PMI. A larger down payment reduces your loan and payment, but it also uses cash you may want for reserves, moving, and furnishing.
• Points: paying points lowers your rate in exchange for upfront cost. Whether it makes sense depends on how long you’ll keep the loan. Ask your lender for a break-even calculation based on your quote.
• Credit: higher scores generally get better pricing. Check your report for errors, pay on time, and avoid new debt before applying.
• Pre-approval: get a full pre-approval, with verified income and assets, before you tour. It’s more reliable than a pre-qualification, and builders take it more seriously.
• Questions to ask lenders: how many loans they close in the Alliance Corridor, typical time to closing, their experience with builders and new construction, and what they do if an appraisal comes in low.

Section 5: New Construction or Resale?

New construction can offer customization, newer systems, builder incentives, and a timeline you can plan around. Considerations include construction timelines, living near active construction, young landscaping, and limited comparable sales in a new community.

Resale offers immediate move-in, mature landscaping, and a clearer picture of what you’re buying. Considerations include competition for well-priced homes, possible updates, and generally no builder incentives.

Builder incentives: rate buydowns, closing cost credits, and design allowances are real and negotiable, but evaluate them carefully. As an October 2026 example, one builder’s advertised 4.99% rate was a 5-year adjustable FHA loan with a 6.645% APR through a specific lender, a very different thing from a 4.99% fixed rate. Compare loan type, APR, deadlines, and lender requirements. See our guide, We’ve Bought 6 New Construction Homes.

Warranties: builder warranties vary. Ask for the written warranty before you sign, read what it covers and for how long, and consider having an attorney review the contract.

Representation: the builder’s sales counselor works for the builder. In most new-construction purchases the builder pays our compensation, so our help costs you nothing extra, and we confirm in writing before you sign. Why you need a Realtor.

Choosing a Lot

Two homes with the same plan can live very differently depending on the lot. Considerations include:

• Backing: greenbelt or open space gives privacy, and busy streets or commercial areas do the opposite.
• Position: cul-de-sacs mean less traffic. Corner lots mean more light and more street exposure.
• Size and shape: more usable yard matters if you want a pool or workshop. Check HOA rules.
• What’s planned nearby: ask for the master plan. Find out what’s planned on empty lots, where schools and retail go, and whether roads will expand.
• Premiums: lot premiums vary by builder and community and are sometimes negotiable. We can’t promise any premium comes back at resale.

Section 6: Common Mistakes

1. Confusing what you qualify for with what’s comfortable. A lender’s maximum isn’t a recommendation. Build a monthly budget with your take-home pay, savings goals, and reserves, and see how the new payment fits. Some buyers try living on the new budget for a few months before they buy.
2. Ignoring resale and exit options. You’re not buying forever. Look at recent comparable sales in the community, and be cautious about buying the most expensive home on the street.
3. Over-customizing. Design centers make it easy to spend a lot. Upgrades usually don’t return their full cost at resale, so decide which ones you’d want to live with regardless.
4. Underestimating ongoing costs. Use the list above and get real quotes.
5. Letting emotion drive the deal. Tour several homes, sleep on it, run the numbers first, and be willing to walk away.

Section 7: A Simple Action Plan

About 90 days out

• Talk to a lender and get pre-approved. Gather two years of tax returns, recent pay stubs, and bank statements.
• Check your credit reports.
• Ask us for a market value estimate and net proceeds estimate for your current home.
• Start touring communities, and test your commute.

About 60 days out

• Narrow to two or three communities and finalize your financing plan.
• If you’re selling, prepare your home and plan your listing date.
• Choose a lot and plan (new construction) or start your resale search.

About 30 days out

• Make offers and negotiate terms and incentives.
• Complete inspections (resale) or design selections (new construction).
• Order the appraisal and submit final lender documents.

Closing

• Final walkthrough, wire funds, and closing. Add buffers for delays, because there are always some.

Frequently Asked Questions

Can I afford a $700K home if I make $150K a year? It depends on your down payment, other debts, and loan type. At today’s rates, the illustrative payment above is about $5,730 to $5,870 a month with 20% down, which is a high share of a $150K gross income. A lender can tell you what you qualify for, and a budget can tell you what’s comfortable.

Should I wait for rates to drop? Nobody can predict rates. Waiting and buying now both carry risks. Talk with a lender about both paths with your numbers.

Is new construction or resale better at this price? It depends on your timeline, priorities, and what’s available. Compare both for your situation.

How much equity do I need? Enough for your down payment, closing costs, moving, and reserves. A 10% to 20% down payment is common at this price, but the right amount depends on your finances.

Do I need 20% down? No. Conventional loans allow less, usually with PMI, and a larger down payment lowers your payment.

Should I sell first or buy first? See Section 3. Each approach has trade-offs.

What’s the 2026 conforming loan limit? $832,750 for a one-unit home in most counties. Loans above it are generally jumbo loans.

Are new homes covered by a warranty in Texas? Builders typically provide their own written warranties, and terms vary. Ask for the document and read it, and consider having an attorney review your contract.

How do I avoid becoming house poor? Build a budget around your actual take-home pay, keep reserves, and stress-test the payment before you commit.
