## Should you take a 12-month or a 15-month lease?

We understand that evaluating a move-in special requires looking past the immediate monthly discount. Evaluating long-term cash flow is second nature to business owners. Analyzing a residential lease demands the exact same mindset.

Our proprietary analysis often reveals that a longer lease term spreads the same free weeks over more months. This mathematical quirk makes the net effective rent look higher on paper. Comparing the totals across a set time frame is the only way to find the actual value.

We created this guide to map out the exact math for 

San Antonio apartment specials

 using a clear, labeled illustration.

Late 2026 data from RealPage Market Analytics shows US apartment concessions averaging 11.1% of asking rent. That figure translates to nearly six weeks free on a standard lease. Our team will break down how these deep discounts interact with a 12 month vs 15 month lease to protect your bottom line.

All examples use the Prose On The Range figures, values as of Oct 25, 2026: $1,215 base, $52.38 in required fees. The 15-month scenarios are hypothetical, to show how the math works. We utilize these specific numbers to ensure accuracy in our calculations.

> Both paths should cover the same 24 months: the first lease plus renewal months to reach 24. Then compare the totals.

## Net effective by term

Current US market data shows concessions are hitting heavily supplied markets hard. San Antonio currently sees discounts on roughly one-third of all stabilized units. We track these metrics to help you capitalize on the best available terms.

With the same 10 weeks free, the concession is worth $2,803.85 either way. Spreading that discount over a longer term simply lowers the monthly deduction by a smaller margin. Our team highlights this spreading effect because it often confuses renters into thinking a 15-month lease is a worse deal.

Property management software like Yardi dynamically prices these units daily based on supply. Algorithms might drop the base rent slightly on a 15-month term to balance expiration dates. We always advise pulling quotes for multiple terms on the exact same day.

| Term | Net effective | True monthly (plus $52.38) |
| --- | --- | --- |
| 12 months, 10 weeks free | $981.35 | $1,033.73 |
| 15 months, 10 weeks free | $1,028.08 | $1,080.46 |
| 15 months, 12 weeks free | $990.69 | $1,043.07 |

The 15-month net effective looks worse with the same weeks. That difference is just the spreading effect in action. Our calculations prove it is not inherently a worse financial decision when comparing a 12 month vs 15 month lease.

## The 24-month total

CoStar Group projects national apartment rent growth to hit 1.9% by the end of 2026. Projections for 2027 show annual rent growth approaching 3%. We use these industry forecasts to model realistic renewal scenarios.

Year two at a flat renewal is $1,267.38. At a 3% increase, the new monthly rate becomes $1,303.83. Our analysts prefer to map out both a flat and a rising market to give you a complete picture.

| Scenario | 24-month total at 0% | 24-month total at +3% |
| --- | --- | --- |
| 12 months, 10 weeks free | $27,613.27 | $28,050.67 |
| 15 months, 10 weeks free | $27,613.27 | $27,941.32 |
| 15 months, 12 weeks free | $27,052.50 | $27,380.55 |

We find three distinct patterns standing out from the data:

1.  **Same weeks, flat renewal is a tie.** You pay the base rent for 24 months minus the exact same concession either way.
2.  **Our calculations show a rising renewal with the same weeks makes 15 months win.** The 3% increase only applies to 9 months instead of 12, saving $109.35 in this scenario.
3.  **More weeks on 15 months makes 15 months the clear winner.** Securing two extra weeks of free rent saves $560.77 over 24 months at a flat renewal.

We find that locking in the longer term acts as a hedge against future inflation. Delaying your exposure to 2027 rent hikes by a full quarter provides tangible financial protection. Business owners understand the value of fixed costs, and this same principle applies here.

## Renewal timing

We always map out the ending month because real estate seasonality directly impacts future pricing. A longer term fundamentally shifts your renewal season to a different time of year. Signing a lease in November means it will end in November on a 12-month term, or February on a 15-month term.

Our research shows national multifamily vacancy is hovering around 8.2% in late 2026. The market is expected to tighten considerably in 2027 and 2028. Pushing a renewal into February often means negotiating during a slower leasing month with less competition.

We recommend reading our complete breakdown on 

when to sign a lease

[/guides/when-to-sign-a-lease/ →](/guides/when-to-sign-a-lease/)

 for more seasonal strategies. Many clients successfully use this strategy to avoid the busy summer season when move-in specials disappear entirely. This proactive approach puts you in the driver’s seat during your next negotiation.

## Early-exit cost

We urge every applicant to scrutinize the early termination and reletting sections before signing. The main drawback with any extended contract is the longer commitment period. Standard US lease break fees in 2026 typically require 60 days of notice plus a penalty equal to 1.5 or 2 months of rent.

Our guide on 

lease addenda red flags

[/guides/lease-addenda-red-flags/ →](/guides/lease-addenda-red-flags/)

 covers exactly what to look for in the fine print. Many modern leases now include strict concession payback language. Breaking a 15-month lease in month eight might force you to repay the entire $2,800 discount up front.

We always remind clients that a longer lease inherently means more months you could owe if plans change unexpectedly. Life events happen, so it pays to understand your maximum financial exposure. Protecting your assets means knowing the exact cost of breaking the contract.

## If you’re on orders

Our military relocation specialists track how BAH follows the duty station, such as MHA TX285. Texas Property Code §92.017 lets a servicemember end a lease on PCS orders or deployment orders of 90 days or more received after signing. You must provide written notice and a copy of the official orders to activate this protection.

We remind our military clients that these federal and state rights can only be waived in a completely separate document. Review the 

Texas military lease clause

[/guides/texas-military-lease-clause/ →](/guides/texas-military-lease-clause/)

 guide for specific legal details. Always ask the property manager how concession payback language interacts with a legal military exit.

We calculate BAH minus the true monthly cost for both lease terms to reveal your actual out-of-pocket expenses. This financial modeling provides clarity for your year-one and year-two budgets. Having this math on hand makes the housing transition significantly smoother.

## How to ask for term options

We strongly advise asking whether the weeks free change with the term length. Most leasing offices utilize dynamic pricing software to calculate several different term lengths simultaneously. Property websites often display only the single most profitable term for the building.

Our team recommends calling the office directly to ask for the exact same unit priced at 12, 13, 14, and 15 months. You should also ask how a standard offer compares to a specific 15 month lease special. Some communities charge a slightly higher base rent on shorter terms to discourage quick turnover.

We find that a higher base rent immediately raises your costs for year one and sets a higher baseline for your future renewal. Evaluating the move-out window is the critical next step, as a 15-month lease ending in a slow month creates a distinct advantage. Winter expirations force buildings to compete harder for your tenancy. Our experience shows that summer expirations land you squarely in the busiest season. Move-in specials shrink rapidly when demand is high during those warmer months. Pricing flexibility completely disappears during this peak period.

| Question to ask | Why it matters |
| --- | --- |
| What special applies to each term? | More weeks free on a longer term can flip the 24-month total |
| Does base rent change by term? | A higher base raises year two too |
| When would each term end? | Sets your renewal season |
| What does early exit cost on each term? | A longer lease means more months at risk |

We ask these specific questions for every building on your shortlist and compile the answers into a single comparative table. This matrix allows you to view the net effective rate, true monthly cost, and the comprehensive 24-month total side by side. Reviewing hard numbers before you tour is the best way to secure a favorable contract.

## A quick way to decide

We look at the average renter timeline to recommend the most cost-effective path forward. The average US renter stays in a unit for about 27 months. Finding the right balance requires evaluating your long-term stability in the area.

Our analysts note that a structure offering a longer lease more weeks free almost always wins on the 24-month total. This mathematical advantage holds true as long as you are highly confident you will fulfill the entire contract. If the weeks free are identical on both terms and you plan to stay at least two years, the final totals land very close together.

We suggest simply choosing the end month that aligns best with your future plans in a tie-breaker scenario. If there is a real chance you will relocate within the first year, the shorter term keeps your financial exposure smaller. Avoiding massive concession payback penalties should be your top priority if your timeline is uncertain.

## How we compare terms for you

We contact each leasing office to uncover exactly what specials apply to every available term length. Send the list of buildings you are currently considering to our office to get started. Evaluating the specific numbers takes the guesswork out of choosing a 12 month vs 15 month lease.

Our service ensures you see precisely which term costs less before you ever sign a legally binding contract.

The resulting report displays the net effective rent, the true monthly payment, and the 24-month total for both options. These calculations include modeled renewal rates at both 0% and +3% to completely protect your budget. We look forward to helping you secure the most advantageous lease possible.

Questions

## Questions about this guide

### Is a 15-month lease cheaper over two years?

Sometimes. With the same weeks free and a flat renewal, the 24-month totals come out the same. A 15-month term wins when it carries more weeks free or when renewal rises, because the increase applies to fewer months.

### What if I get orders mid-lease?

Texas Property Code §92.017 may let you end the lease with written notice and a copy of PCS or 90+ day deployment orders received after signing. Check for concession payback language too.

### Can you guarantee a price or approval?

No. The community sets both pricing and approval. We pull prices every morning and confirm the numbers with the leasing office before you sign.
