Buying, building, or upgrading your school’s facility isn’t a single decision — it’s five different paths, each with its own timeline. Staying in your current space with a modified lease can take as little as 6–7 months. Building new construction from scratch averages 13 or more months. Getting the timeline right, before you commit to a path, is what keeps a facility project from disrupting a school year it wasn’t supposed to touch.
Why Buy Your School Building
Buying gives your school three things a lease can’t:
- Stability. Ownership makes your school a permanent fixture in your community, rather than a tenant subject to a landlord’s plans.
- A financial asset. Building ownership builds equity over time instead of paying down someone else’s mortgage.
- Autonomy. You control your own improvements and expansion timeline, instead of negotiating every change with a landlord.
The challenge most charter leaders run into isn’t wanting to buy — it’s the same one every school faces: needing more space while working within real budget constraints.
Today’s School Buying Landscape
The market conditions shaping charter school facility decisions have shifted since this was last updated, and they’re worth knowing before you set a timeline:
- Construction costs are still climbing. Construction inputs are running roughly 40% higher than early 2020 levels, with costs still increasing another 5% or so year-over-year.¹
- Tariffs are a real line item now. Steel, aluminum, and imported metal furniture — all common in school construction — currently face tariffs as high as 50%, which shows up directly in a construction budget.¹
- Skilled labor is tight. Roughly 61% of U.S. metro markets are currently supply-constrained for construction labor, a number expected to keep climbing.¹ That means less flexibility in your contractor’s schedule, so build in buffer time.
- Borrowing costs have room to plan around. Commercial real estate loan rates currently range roughly 5%–12.5% depending on the loan type and your school’s financial profile, after the Federal Reserve cut rates through the second half of 2025 and held steady into 2026.² A specific rate quote depends on your school’s financials — but it’s a very different environment than it was even two years ago, and worth revisiting if you last checked rates a while back.
Given these conditions, charter school leaders benefit from a strategic, not reactive, approach to facilities.

Strategic Approaches to Your Facility Decision
There are three broad paths: stay in your current space, buy your own building, or take on new construction. A few ways to make any of them work harder for your budget:
- Phase the work. Phased construction or renovation lets you manage cash flow instead of financing everything at once.
- Right-size your space. Define the space your mission actually requires before you go looking — it’s easy to overbuild.
- Look at what you already have. Renting out unused space, or repurposing an underused wing, can generate funds toward your next project.
- Watch the market and move when it aligns. Conditions shift; the school that’s ready to act when a good opportunity appears has an advantage over one that’s just starting to plan.
Three Financial Benchmarks Worth Tracking
- Average Daily Attendance (ADA): Aim to fill at least 80% of your facility’s capacity based on ADA, so you’re not paying for space you don’t need.
- Rent-to-Revenue Ratio: Keep revenue at least 5–6 times your lease costs for financial stability.
- Coverage Ratio: Keep net income at least 120% of your lease costs to protect your school’s financial health.
How Far in Advance to Plan: Timeline by Scenario
How early you need to start depends entirely on which path you’re on. Based on Grow Schools’s underwriting experience across charter school facility transactions,³ here’s what each path typically takes from first conversation to move-in day:
Building new construction — average process 13+ months
| Timing | Milestone |
|---|---|
| Month 1 | Scope & confirm need |
| Months 2–3 | Find building & size improvements |
| Month 4 | Propose solution & execute LOI |
| Month 5 | Execute PSA/lease |
| Months 6–7 | Close on transaction |
| Month 8 | Complete prep |
| Months 9–12 | Build |
| Month 13 | Move in |
Moving to a forever home with improvements — average process 9–11 months
| Timing | Milestone |
|---|---|
| Month 1 | Scope & confirm need |
| Month 2 | Propose solution & execute LOI |
| Month 3 | Execute PSA/lease |
| Months 4–5 | Close on transaction |
| Month 6 | Complete prep |
| Months 7–10 | Build |
| Month 11 | Move in |
Moving to a forever home without improvements — average process 9–11 months
| Timing | Milestone |
|---|---|
| Month 1 | Scope & confirm need |
| Month 2 | Execute LOI |
| Month 3 | Execute PSA/lease |
| Months 4–5 | Close on transaction |
| Months 6–9 | Build |
| Month 10 | Move in |
Staying in your current space with a modified lease — average process 6–7 months
| Timing | Milestone |
|---|---|
| Month 1 | Scope & confirm need |
| Month 2 | Execute LOI |
| Month 3 | Execute PSA/lease |
| Months 4–5 | Close on transaction |
| Month 6 | Move in |
Staying in your current space with your lease as-is — average process 6–7 months
| Timing | Milestone |
|---|---|
| Month 1 | Scope & confirm need |
| Month 2 | Execute LOI |
| Month 3 | Execute PSA/lease |
| Months 4–5 | Close on transaction |
| Month 6 | Move in |
The pattern across every path: the first month (scoping and confirming need) and the final stretch (closing and moving in) are non-negotiable minimums. The variable is what happens in between — and that’s exactly where a phased approach or a clear space plan can shorten your timeline.

Building Your Facility Plan Early
Whichever path you choose, starting early gives you room for the delays every facility project runs into. A few habits that help:
- Run an annual building audit. Know your facility’s condition and whether it can meet your needs before you’re forced to react to a problem.
- Plan for costs beyond the purchase price. Future maintenance, energy efficiency, and your school’s growth trajectory all affect the real cost of a facility decision.
- Review your lease and contracts now, not later. Know your lease expiration date and confirm compliance with regulations like Prop 39 well before you need to act on them.
Make an Ideal Space Plan
If buying is the right move, build a space plan around your mission and growth goals, not just your current headcount:
- What spaces does your mission actually require?
- How many classrooms do you need — today and in five years?
- How many bathrooms, and how much hallway and office space?
How Grow Schools Can Help
Money to Buy Your School is Grow Schools’s facility financing solution for charter schools. We buy your building and lease it back to you, often at reduced monthly rent, with a clear path to ownership — and you can close on a property in as few as 90 days. See how the timing played out for DuBois Integrity Academy, which used a Grow Schools partnership to buy their building, then expand into additional buildings as they grew from 578 to more than 1,300 students.

Frequently Asked Questions
How long does it take to buy a school building?
It depends on the path. New construction averages 13 or more months from scoping to move-in. Moving to a forever home that needs improvements averages 9–11 months. Staying in your current space with a new or modified lease is the fastest option, averaging 6–7 months.
What’s the very first step in the timeline?
Scoping and confirming your need — typically month one on every path. This is where you define what your facility actually has to do for your school before you start evaluating buildings or contractors.
Is it a good time to buy given current construction costs?
Construction costs remain elevated — inputs are running about 40% above early-2020 levels, with continued increases expected — and tariffs on steel, aluminum, and imported furniture add to project costs.¹ That doesn’t rule out buying or building; it just makes the case for phasing construction, right-sizing your space plan, and locking in financing terms early rather than waiting.
What financial ratios should I track before committing to a facility?
Three: Average Daily Attendance at 80%+ of your facility’s capacity, a rent-to-revenue ratio of at least 5–6x, and a coverage ratio (net income to lease costs) of at least 120%.
How does Grow Schools’s facility financing work?
We buy your school and form a long-term partnership with you, leasing it back — often at reduced monthly rent, with rent increases limited to cost-of-living adjustments. Rent payments set you on a path to ownership over time.
How quickly can Grow Schools close on a building?
In as few as 90 days once you’re in the process — though as the timelines above show, the full journey from scoping your need to moving in typically takes longer, depending on which path you’re on.
