# What Is the 3-3-3 Rule for Buying a House? An El Paso Reality Check > What is the 3-3-3 rule for buying a house? Plan to stay 3 years, cap the price at 3 times your income, keep 3 months of payments saved. Here is how that rule of thumb holds up against real El Paso numbers. **Author:** Marina Ramirez **Published:** 2026-08-14 **Category:** Buyer's Guide --- The 3-3-3 rule for buying a house is a quick affordability check: plan to stay in the home at least 3 years, spend no more than 3 times your gross annual income on the purchase price, and keep at least 3 months of housing payments in savings after closing. If a purchase passes all three tests, the thinking goes, you are probably not overreaching. It is a useful gut check, but it is a rule of thumb, not a law, and you will find slightly different versions of it depending on who is explaining it. In this post I will define the rule honestly, show you where the definitions vary, and then stress-test each of the three threes against current El Paso numbers, including our home prices, our mortgage rates, and our famously high property taxes. --- ## The 3-3-3 Rule, Defined The most common version of the rule breaks down like this. ### Three Years in the Home Plan to own the house for at least three years before you sell. Buying and selling both come with transaction costs: closing costs when you buy, agent commissions and closing costs when you sell, plus moving expenses on both ends. Those costs add up to a meaningful percentage of the home's value, and if you sell after only a year or two, modest appreciation usually has not had time to cover them. Three years is the rough break-even horizon in a normally appreciating market. Five years is safer. ### Three Times Your Income Cap the purchase price at roughly three times your gross annual household income. A household earning $80,000 a year would shop below $240,000. The idea is to keep the total debt load modest relative to earnings so the monthly payment does not crowd out everything else in the budget. ### Three Months of Payments in Reserve After you pay the down payment and closing costs, you should still have at least three months of full housing payments sitting in savings. Not invested, not promised to furniture, just liquid. A roof leak or a gap between jobs should not put your mortgage at risk in month two of homeownership. ### The Definitions Vary, and That Is Worth Knowing The 3-3-3 rule is folk wisdom, not an official lending standard, so you will see variations. Some versions swap in "no more than 30% of your monthly income on the housing payment" for the income test. Others frame the reserve rule as three months of total expenses rather than three months of housing payments. A few stretch the holding-period rule to five years. None of these versions comes from a regulator or a lender. Mortgage underwriters do not use the 3-3-3 rule at all; they qualify you on debt-to-income ratios, credit history, and documented assets. That is exactly why the rule survives: it is stricter than what a lender will approve, which makes it a decent guardrail against borrowing the maximum just because you can. --- ## Stress Test 1: Does "3 Times Your Income" Work in El Paso? Now let us hold the rule up against real local numbers. As of mid-2026, El Paso's typical home value sits around $238,000 by Zillow's estimate, the median listing price is around $290,000 according to Realtor.com, and median sale prices reported by sites like Redfin and Homes.com have generally landed in the $250,000 to $273,000 range. Treat all of those as moving targets rather than exact figures, but the band is clear: the middle of our market lives roughly between $240,000 and $290,000. Run the 3x income math backward and the rule says a household needs about $80,000 to $97,000 in gross annual income to buy a median El Paso home. Some El Paso households clear that bar comfortably, especially dual-income families and military households with allowances. Many do not. That is the first honest finding: in El Paso, the 3x rule is conservative, and following it strictly may point you below the median price point, toward areas like Socorro, Horizon City, the Lower Valley, and parts of Northeast El Paso where solid homes still list below $240,000. Is that a flaw in the rule? Not exactly. A lender will usually approve you for more than 3x income, sometimes meaningfully more depending on your debts and rate. The gap between what the rule allows and what the bank allows is the space where payment stress lives. El Paso adds a twist, though, and it is a big one. ### The Property Tax Twist The 3x income rule was coined for a generic American market. El Paso is not generic: our combined effective property tax rate runs around 2.3% to 2.6%, among the highest in Texas, because we have no state income tax and a smaller commercial tax base than the big metros. On a $250,000 home, that is roughly $5,800 to $6,500 a year in property taxes before exemptions, which adds several hundred dollars to every monthly payment. Practically, that means a $250,000 house in El Paso costs more per month than a $250,000 house in most states, even at the same mortgage rate. If you use the 3x rule here, treat it as a ceiling, not a target, and make sure you file your homestead exemption, which removes $100,000 of your home's value from school district taxation in Texas. I break down how the exemption and the protest process work in my guide to the [homestead exemption and property tax protests in El Paso](/en/blog/homestead-exemption-property-tax-protest-el-paso-2026). --- ## Stress Test 2: What Do "3 Months of Reserves" Actually Look Like Here? Let us put dollars on it, using ranges you can update as the market moves. Take a $250,000 purchase with 10% down, leaving a $225,000 loan. With 30-year fixed rates hovering around 6.0% to 6.5% in mid-2026, principal and interest lands roughly between $1,350 and $1,425 a month. Add property taxes in the $480 to $540 a month range before exemptions, plus homeowners insurance on top, and the true monthly housing payment for a median El Paso home sits somewhere around $1,900 to $2,100 for many buyers. Three months of that is roughly $5,700 to $6,300 in reserves, after your down payment and closing costs are paid. That is the part of the 3-3-3 rule I would defend most strongly, because it is the one buyers skip most often, with every available dollar assigned to the down payment and nothing surviving closing day. El Paso has generous down payment help that makes the reserve goal much more reachable: local and state programs can cover thousands of dollars of down payment and closing costs, which frees your own savings to stay in the emergency fund. I keep a current rundown in my guide to [down payment assistance programs in El Paso](/en/blog/down-payment-assistance-el-paso-2026), and if you are early in the process, my [first-time buyers page](/en/first-time-buyers) explains how I sequence all of this with clients. One more honest note: three months is a floor, not a badge of honor. If your income is variable, commission-based, or tied to a single employer, six months is the wiser number. --- ## Stress Test 3: The "3 Years" Rule Meets Fort Bliss The holding-period rule is where El Paso genuinely diverges from the national script. For a civilian buyer with a stable job, three years is a reasonable minimum horizon here. El Paso appreciates steadily rather than spectacularly, so a short hold gives prices little time to outrun your transaction costs. But El Paso is a military town, and Fort Bliss families often receive Permanent Change of Station orders on two-to-four-year cycles. Under a strict reading of the 3-3-3 rule, a soldier who might PCS in under three years should not buy at all. Reality is more nuanced, and thousands of Fort Bliss families buy successfully. Three factors change the math: - **VA loans lower the entry cost.** With no down payment required and competitive rates, the cash you need to recover through appreciation is smaller than in a conventional purchase. - **Renting the home out is a real exit.** El Paso's steady rental demand near post means a PCS does not force a sale. Many military owners keep the home as a rental and let a tenant carry the mortgage. - **VA loan assumptions exist.** In some cases a buyer can assume a seller's low-rate VA loan, which can make your home unusually attractive when you sell. So for military buyers, I translate the 3-years test into a different question: if orders came in 18 months, would this house work as a rental, or would you be forced to sell at a bad moment? If the answer is "forced sale," the rule is warning you correctly. If the house would rent well, the rule is too blunt for your situation. My [military and PCS page](/en/military) goes deeper on how I structure purchases around orders, and if you are weighing whether to buy at all this tour, start with my honest comparison of [renting versus buying in El Paso](/en/blog/renting-vs-buying-el-paso-2026). --- ## Where the 3-3-3 Rule Helps, and Where It Misleads A fair scorecard for El Paso in 2026 looks like this. ### Where It Helps - **It counters maximum-approval thinking.** The most common affordability mistake is borrowing whatever the lender approves. The 3x cap forces a gap between "approved" and "wise," and in a high-property-tax city that gap protects you. - **The reserve rule prevents the worst outcomes.** Nearly every homeownership horror story starts with zero savings after closing. Three months of payments is the cheapest insurance there is. - **It slows down impulse purchases.** Anything that makes a buyer pause and run numbers before writing an offer is doing useful work. ### Where It Misleads - **It ignores interest rates.** Three times your income at a 6.5% rate is a very different monthly burden than the same price at 4%. A payment-based check, like keeping your total housing payment under roughly 28% to 30% of gross monthly income, adapts to rates. The 3x price cap does not. - **It ignores local taxes and insurance.** As covered above, El Paso's effective property tax rate of roughly 2.3% to 2.6% makes any price-based national rule too generous here unless you adjust for it. - **It ignores your other debts.** A household with no car payments and no student loans can safely carry more house than the same income with $900 a month in obligations. Lenders account for this through debt-to-income ratios. The 3-3-3 rule cannot. - **The 3-year test misreads military life.** As shown above, PCS timelines demand a rent-it-out analysis, not a simple holding-period rule. The honest conclusion: the 3-3-3 rule is a good first filter and a bad final answer. Pass it, and you are probably in safe territory. Fail one leg of it, and the right response is analysis, not automatic disqualification. --- ## How I Would Actually Run the Numbers in El Paso If you want a sturdier version of the rule for this market in 2026, here is the sequence I walk buyers through: 1. **Start from the monthly payment, not the price.** Take your gross monthly household income, multiply by roughly 0.28 to 0.30, and treat that as your total housing payment ceiling, including principal, interest, taxes, and insurance. 2. **Build the payment with El Paso taxes in it.** Use a 2.3% to 2.6% effective tax rate before exemptions when you estimate, then file your homestead exemption immediately after closing. 3. **Get pre-approved, then shop below the approval.** The letter tells you the bank's ceiling. Your budget should sit comfortably under it. 4. **Protect three to six months of payments in reserve.** Use assistance programs for the down payment where you qualify so your own savings survive closing. 5. **Run the 18-month test on your timeline.** Civilian or military, ask what happens if life forces a move early. If the answer is a forced sale in under three years, either buy less house or wait. 6. **Choose the loan that fits the plan.** FHA, VA, and conventional loans each change the down payment and reserve math differently. My [FHA and VA loans page](/en/fha-va-loans) compares them for El Paso buyers. Where does the market itself fit in? Current conditions matter less than the rules above, but they do matter. Inventory in El Paso has been running in the low thousands of active listings with balanced-to-buyer-friendly conditions at mid-year, which means buyers who follow conservative rules are not being punished for patience.

No. Lenders do not use it. Mortgage approval runs on debt-to-income ratios, credit scores, employment history, and documented assets. The 3-3-3 rule is a consumer rule of thumb that is intentionally stricter than typical lending limits, which is what makes it useful as a self-imposed guardrail. ### What is the difference between the 3-3-3 rule and the 28/36 rule? The 28/36 rule is payment-based: keep your housing payment under about 28% of gross monthly income and your total debt payments under about 36%. The 3-3-3 rule is price-based on the income leg, and it adds the holding period and reserves. The 28/36 rule adapts to interest rates and El Paso's high property taxes automatically, so I lean on it more for the affordability question, while keeping the 3-3-3 rule's reserve and time-horizon tests. ### How much income does the 3-3-3 rule say I need for a median El Paso home? With median sale prices roughly in the $250,000 to $273,000 range as of mid-2026, a strict 3x income cap implies household income of about $83,000 to $91,000. Lenders will typically qualify buyers with less income than that for those prices, which is exactly the tension the rule is designed to create. Buying below the median, common in Socorro, Horizon City, and parts of Northeast El Paso, brings the required income down substantially. ### Does the 3-year rule mean military families should not buy in El Paso? Not automatically. A strict reading says do not buy if you may move within three years, and PCS cycles often run two to four years. But VA loans reduce upfront cost, El Paso's rental demand near Fort Bliss gives owners a realistic keep-and-rent exit, and VA loan assumptions can help at resale. The better question is whether the home would work as a rental if orders arrived early. ### Should the 3 months of reserves be in cash? Yes, liquid and boring. A savings account or money market fund you can tap in days, not investments that might be down the month you need them, and not home equity you would have to borrow against. For a median-priced El Paso home in 2026, three months of full payments is very roughly $5,700 to $6,300. ### Is the 3-3-3 rule too conservative for El Paso's market? On the income leg, somewhat, because El Paso prices are low relative to national averages, and on the time leg it is too blunt for military buyers. But our high property taxes push in the opposite direction and make conservative price caps more sensible here than in low-tax states. Use it as a first filter, then run a payment-based budget with real El Paso tax numbers before you decide. --- *Want to stress-test your own numbers instead of a rule of thumb?
