Houston self-storage is horizontal sprawl — pad sites on US-59, I-10, and SH-288 corridors, big-box conversions in aging retail rings, and industrial-to-storage flex plays in Northwest Houston and Pasadena edges. It is also a flood and insurance market: Harris County AE blocks and post-storm premium cycles belong in every opex stack before you quote DSCR.
This guide is the Houston metro storage thesis for Jaken Finance Group — bridge during lease-up at 8.99%–13.5% interest-only, permanent DSCR at 5.75%–10.5% on stabilized units. Texas commercial hub: commercial lending Texas. Nationwide storage: self-storage facility financing · SBA self-storage loans.

Pad ground-up vs corridor conversion
Ground-up pad (typical exurban file). Flat pad on entitled land along a highway feeder — drive-up perimeter, climate building, gate, and office. Watch stormwater, flood elevation, and TXDOT access.
Conversion (typical infill file). Empty big-box or flex with parking — demising, HVAC, sprinklers. Basis advantage until roof and fire-life-safety bids arrive.
| Dimension | Highway pad ground-up | Infill conversion |
|---|---|---|
| Basis (planning) | $115–$175 / sf rentable all-in | $55–$100 / sf + conversion |
| Diligence | FEMA flood, detention | Change of use, roof age |
| Rent band | Drive-up $0.95–$1.35 / sf / mo; climate premium | Similar; couponing near new supply |
| Lease-up | 18–36 months | 14–22 months if hybrid first in ring |
| Exit | DSCR investor or regional operator | Same |
National pipeline context: ~44M sq ft under construction nationally per Yardi Matrix / StorageCafe — Houston participates in Sun Belt supply growth even without the highest metro percentage.

Houston metro supply — 2026 planning table
| Submarket | 2026 planning economics | Supply / risk note |
|---|---|---|
| Northwest Houston (Cy-Fair, Tomball) | Strong rooftops; climate $1.10–$1.55 / sf / mo | Multiple new deliveries 2025–2026 |
| Katy / West Houston | Household growth | REIT flags on I-10 |
| Pearland / South Houston | Mix pad and conversion | Flood fringe diligence |
| North Freeway (Spring, The Woodlands edge) | Higher-income climate demand | Land basis rising |
| East / Pasadena corridor | Lower basis conversions | Industrial adjacency — environmental review |
| Sugar Land / Fort Bend | Premium climate | Higher tax; higher $/sf required |

Economic occupancy — Houston underwriting
Economic occupancy funds DSCR. Physical locks with promotional rents do not.
| Metric | Houston planning band |
|---|---|
| Break-even occupancy | 60%–65% economic |
| Expense ratio | 35%–40% — stress insurance high in flood-adjacent sites |
| Ancillary | 8%–15% at maturity |
| Lease-up timeline | 18–36 months new supply |
Worked example (composite) — Northwest Houston climate pad
Composite, not a live quote. 3.2-acre pad, 71,000 rentable sf, climate-heavy. Land $890,000. Vertical + site $8,240,000. Soft $470,000. All-in $9,600,000. Site outside AE flood — verified with elevation cert.
| Stack | Amount |
|---|---|
| Construction 63% LTC | $6,048,000 at 11.125% IO |
| Sponsor equity | $3,552,000 |
| Interest reserve | 16 months in holdback |
Lease-up: month 10 48% economic; month 18 72%; month 23 84% at $1.32 / sf / month blended.
| Stabilized month-23 | Annual |
|---|---|
| Unit income at 84% | $992,000 |
| Ancillary | $55,000 |
| OpEx (36%) | $376,920 |
| NOI | $670,080 |
Value at 6.15% cap ≈ $10,896,000. DSCR at 67% LTV ≈ $7,300,000 at 7.0% → coverage ~1.21 stressed. Twenty-three months IO ≈ $1.29M — plan reserves accordingly.
Worked example (composite) — Katy corridor big-box conversion
Purchase $2,320,000. 76,000 sf rentable after conversion. Conversion $1,780,000. All-in $4,100,000.
| Item | Value |
|---|---|
| Bridge 69% LTC | $2,829,000 at 10.625% IO |
| Month-14 economic occupancy | 76% |
| Stabilized NOI | $341,000 |
| DSCR refi 68% LTV on $5.05M | $3,434,000 at 7.25% |
Flood insurance was $0 on elevated site — do not copy opex from a Pearland AE comp.

Local risk — flood, insurance, taxes, supply
Flood. Harris County AE sites need flood insurance and engineered drainage — or pick a different pad. Lenders decline greenfield in VE without heroic equity.
Insurance. Hail and wind on drive-up rows; post-storm market cycles can add $30K–$80K/yr to opex on large sites. Quote before LTC.
Property tax. Texas 1.8%–2.4% effective on many commercial parcels — model at post-construction assessed value. January 1 appraisal date means year-two jump.
Supply. Houston builds with the Sun Belt. Model competing deliveries within three miles and rate compression in downside cases.
Non-judicial foreclosure. Texas power-of-sale is fast — construction LTC stays 60%–70% on greenfield for a reason.
Financing sequence
- Bridge 8.99%–13.5% IO — LTC on purchase + budget.
- Draws through CO with third-party inspections.
- Lease-up reporting — economic occupancy monthly.
- DSCR 5.75%–10.5% or SBA 10%–15% down when stabilized.
Harris County entitlement — pad vs conversion with flood review
Houston storage from Jaken Finance Group always includes FEMA flood and stormwater in the entitlement story — not a refi surprise.
Northwest / Katy highway pad (greenfield)
- Zoning — verify commercial or industrial storage use; Harris County ETJ cities vary (Cypress, Katy, Tomball).
- FEMA panel — pull AE/VE status before land hard money; elevation certificate if in 500-year fringe.
- Detention engineering — Harris County Flood Control District criteria; often 15%–25% of site budget.
- TxDOT driveway — US-290 and I-10 frontage permits add months if median opening required.
- Building permit and CO — wind and hail design for drive-up roof rows.
Pads in AE flood zones face 60% LTC caps and mandatory flood insurance — or choose a different site.
Katy / infill conversion
- Change of use — Harris County or city of Houston plan review on former retail.
- Roof age and hail history — insurance underwriter asks before Jaken Finance Group locks LTC.
- Sprinkler and egress — Houston Fire Marshal on big-box demising.
- Environmental — prior dry cleaner or auto use on pad edges triggers Phase I/II.
- CO — phased if drive-up opens before climate hall.
Conversion entitlement 4–8 months on life-safety; greenfield 10–16 months including detention.
Month-by-month lease-up — Northwest Houston composite (71,000 sf)
| Month | Economic occ. | Mo. collected | Mo. opEx | Mo. NOI | Notes |
|---|---|---|---|---|---|
| 5 | 26% | $25,400 | $11,200 | $14,200 | Outside AE — no flood premium |
| 10 | 48% | $46,900 | $17,800 | $29,100 | I-10 corridor competitor opens |
| 14 | 62% | $60,600 | $21,800 | $38,800 | Hail claim on gate roof — reserve draw |
| 18 | 72% | $70,400 | $25,400 | $45,000 | Approaching DSCR quote |
| 21 | 79% | $77,200 | $27,900 | $49,300 | Trailing collections to lenders |
| 23 | 84% | $82,100 | $29,600 | $52,500 | Takeout at 67% LTV |
| 26 | 87% | $85,000 | $30,600 | $54,400 | Post-refi stabilization |
IO on $6.048M at 11.125% ≈ $56,153/month. Texas property tax modeled at 2.0% on finished value — year-two jump after January 1 appraisal.
Three-mile supply map — Houston methodology
Houston participates in national ~44M sf pipeline without one headline metro percentage — submarket maps matter more:
- Ring facilities along highway feeder — Cy-Fair customers rarely cross-comp with Pearland.
- Harris County Appraisal District parcels for new vertical — permit lag vs Yardi.
- Flood overlay — exclude AE comps from “low opex” benchmarks; insurance is not optional.
- Industrial conversion — Pasadena corridor prior use environmental flags on map legend.
- Household sf ratio — Katy and Tomball rings add rooftops faster than inner-loop conversion submarkets.

Bridge-to-SBA — Houston owner-operator timeline
| Month | Event |
|---|---|
| 0 | Bridge close — pad or conversion |
| 1–10 | Draws; detention and utility |
| 11 | CO |
| 15 | 60%+ economic — SBA CDC contact if operator on-site |
| 19 | 78%+ economic — 504 application |
| 23–25 | SBA permanent — ~10%–15% down |
| Fallback | DSCR 5.75%–10.5% at 68% LTV — faster, more equity |
Texas non-judicial foreclosure keeps construction leverage conservative — equity and IO reserve prove seriousness.
Worked deal — Pearland AE avoidance vs Katy conversion (composite)
Scenario A — Pearland pad in AE (declined greenfield). Sponsor redirected to Katy conversion — 76,000 sf rentable, all-in $4.1M, outside flood zone.
| Item | Value |
|---|---|
| Bridge 69% LTC | $2,829,000 at 10.625% IO |
| Flood insurance | $0 on elevated infill |
| Month 14 economic | 76% |
| DSCR refi month 19 | $3.434M at 7.25% — 68% LTV |
| NOI | $341,000 / yr |
Scenario B — same sponsor on AE pad. 60% LTC max, flood premium $48K/yr, DSCR 1.08 stressed — file never left committee. Flood map row one beats rate discussion.
