The St. Louis BRRRR Strategy: Brick Two-Family Edition

The BRRRR playbook — buy, rehab, rent, refinance, repeat — works best where three numbers line up: cheap entry, real rents, and an appraisal that supports the refi. St. Louis brick two-families line up all three better than almost any asset in the Midwest. Here is the complete playbook.

Why the brick double works

St. Louis built tens of thousands of side-by-side brick two-families between 1890 and 1940, mostly in South City. Today that stock trades:

Stage	Number
As-is acquisition	$60K–$140K
Rehab (masonry-first)	$40K–$75K
Renovated appraisal	$140K–$215K
Gross rent (both units)	$1,750–$2,400/mo

Two units per roof means the rent stack carries the ratio, and the brick construction — properly repointed — outlasts every mechanical inside it. The Bevo Mill corridor is the classic stacking lane; Dutchtown runs deeper basis with softer blocks.

The 2026 market backdrop

BRRRR math depends on two market readings: how much negotiating room you have at purchase, and whether values are still rising into the appraisal. St. Louis currently offers both.

Metro indicator (St. Louis MSA)	A year earlier	Latest
Median listing price	$299,900 (Sep 2025)	$285,950 (Sep 2026)
Active listings	6,154	7,154
Median days on market	46	50
FHFA house price index	Q2 2025	+4.1% year over year (Q2 2026)

Sources: Realtor.com series via FRED for listing price, active listings, and days on market; FHFA all-transactions index via FRED.

Read those together. About 1,000 more listings and slower sales mean sellers of tired doubles are more open to as-is offers. Meanwhile the FHFA index, which tracks repeat sales, kept climbing. That is a good setup for a buyer who purchases on today’s softer listing market and refinances on a value index that is still moving up.

One caution: those are metro-wide medians, and they include the suburbs. South City doubles trade far below the metro median. Use them for direction, not for your ARV.

The worked example

Real numbers from the pattern we fund through the St. Louis hub:

1. Buy: $92,000 side-by-side double, one unit vacant, parapet cracking — funded on Missouri hard money at 87% LTC, 9-day close, 10.75% IO
2. Rehab: $58,000 — tuckpointing and parapet rebuild first, box-gutter relining, dual furnaces, kitchens and baths
3. Rent: $1,095 + $1,050 = $2,145/mo gross on 12-month leases
4. Refinance: appraisal $198,000; Missouri DSCR at 72% LTV ≈ $142,500 — retiring the $150K all-in with modest cash left in
5. Repeat: equity recycled into the next double on a walked block

Coverage math at refi: gross $2,145, vacancy 6%, property tax ~$160/mo at reassessed value, insurance ~$210, maintenance and management ~$290 → NOI ≈ $1,355 against debt service ≈ $1,050. The ratio clears with margin.

The three St. Louis-specific gates

1. Masonry first

Tuckpointing runs $8–$14/sq ft, parapet rebuilds hit five figures, box gutters fail invisibly. Get the masonry bid from a masonry contractor before LOI and put it in draw one. Files that treat brick as “no exterior scope” stall at draw three, every time.

2. The jurisdiction line

The City of St. Louis and St. Louis County split in 1876 — separate assessors, recorders, and permit offices. Comps never cross the line, and neither do permit assumptions. City files need the Certificate of Inspection; county files need the municipality’s own re-occupancy inspection (Ferguson’s checklist is not Florissant’s). Schedule at rough-in — see the North County guide for how the yield corridors handle it.

3. Reassessment honesty

Model property tax at your purchase price, not the seller’s bill, with 10%–20% contingency. The refi ratio that cleared on the seller’s homestead assessment and fails on yours is the most preventable dead deal in the metro.

The City Certificate of Inspection, step by step

The city process is predictable once you know the rules. Per the City of St. Louis residential occupancy permit page, checked October 2026:

• Every city parcel is covered. All property sits in a Housing Conservation District under Ordinance No. 71835, so every rental unit needs a Certificate of Inspection before a tenant moves in.
• Fee: $120 per application. It rises to $200 if inspectors find someone already living in a unit without a current certificate.
• Scheduling window: the earliest slot is 3 business days after you apply; the latest is 15 days out. Apply when the unit is truly ready.
• Validity: a certificate lasts 12 months. Rentals need reinspection every three years or when occupancy changes.
• Occupancy limit: the inspection sets how many people may live in each unit, and no more than three unrelated persons may share a dwelling.

On a two-family, that means two applications and two certificates — one per unit. Since you turn units in sequence, plan two inspection dates. Unit one’s certificate should be in hand before unit two’s rehab is finished.

The inspection checks minimum code items under the International Property Maintenance Code. It is not a full building inspection. Hire your own inspector before closing.

Property tax: Missouri’s 19% rule and the odd-year cycle

Two Missouri rules drive the tax line in your DSCR model. Under RSMo 137.115, residential property is assessed at 19% of market value. The same statute sets new values as of January 1 of each odd-numbered year. Those values carry into the following even year.

That timing matters for a BRRRR. A double bought and rehabbed during 2026 will be valued fresh for the 2027 cycle. The first full-year bill after your refinance will likely reflect your renovated condition.

Illustration: a renovated double appraised at $198,000 has an assessed value of $198,000 × 19% = $37,620. Your bill is that assessed value divided by 100, times the combined levy for your tax-rate area. Pull the current levy from the city Collector of Revenue for your exact parcel before you finalize the refi model.

Lead paint and pre-1978 rules

Nearly every South City double predates 1978, so federal lead rules apply. The EPA Renovation, Repair and Painting Rule requires firms that disturb lead paint in pre-1978 homes to be EPA- or state-certified. They must also use certified renovators who follow lead-safe work practices. That covers outside contractors and in-house maintenance staff.

For a BRRRR operator, the practical steps are simple:

1. Ask every GC and painter for their firm certification before they bid
2. Put lead-safe setup and cleanup into the window, trim, and porch line items
3. Keep the paperwork in the draw file; it shows the work was done correctly

Window and porch work on old brick disturbs the most painted surface. Price it honestly.

Missouri lease rules that touch the refinance

Your DSCR refinance leans on clean leases. Missouri’s security deposit law, RSMo 535.300, sets three rules worth building into your lease template:

• A deposit may not exceed two months’ rent
• It must be held in a federally insured bank, credit union, or depository institution
• Within 30 days after the tenancy ends, return it or send an itemized list of damages with any balance

On a two-family, keep a separate ledger for each unit’s deposit. Appraisers and underwriters often ask for the rent roll and leases together. Clean deposit records make the file look professional.

Timeline reality

Month	Milestone
0	Close on hard money (7–14 days from contract)
1–4	Masonry + mechanicals + unit one turn
4–6	Unit two turn; occupancy inspection scheduled at rough-in
5–7	Lease-up, staggered so one rent always flows
7–9	DSCR refi on executed leases and passed inspection

Nine months buy-to-refi is honest for a first file. Operators who compress it do so on permit sequencing, not construction speed.

Refinance file checklist for a St. Louis double

Gather these before you order the appraisal. Missing items push the closing date, and every week costs bridge interest.

Document	Why the underwriter wants it
Executed 12-month lease for each unit	Rent used in the coverage ratio
Two or more months of rent deposits	Shows the tenants actually pay
City Certificate of Inspection per unit (or county re-occupancy approval)	Proves the units may be legally occupied
Final draw inspection and lien waivers	Confirms the rehab is complete and paid
Insurance quote on the renovated value	Feeds the expense side of the ratio
Tax estimate at your purchase or appraised value	Avoids the reassessment surprise
Masonry contractor invoice	Supports the appraiser’s condition rating

Sizing note: Jaken Finance Group DSCR loans run 5.75%–10.5% with up to 80% LTV on a cash-out refinance for qualified borrowers. The worked example above stops at 72% because coverage, not the leverage cap, limits most St. Louis doubles. Run your own numbers in the DSCR calculator at both 72% and 80% before deciding how much cash to pull.

Where it goes wrong

• Cross-corridor comps — Tower Grove South premiums on Bevo files inflate ARV $30K–$60K past what the appraiser will sign
• Lease-up optimism — corridor lease comps set the rent, not listing aspirations; stagger the two turns
• Reserve breach — 6–8 months IO reserved; the permit queue, not the rehab, is what usually eats month eight
• Skipping the historic-credit question — on qualifying gut rehabs in register districts, Missouri’s 25% credit changes the math; read the historic tax credit guide before demo

Managing brick stock after the refinance

The BRRRR cycle does not end at the refi — and brick two-families reward owners who budget the long game. Put a small masonry reserve in the post-refinance operating model: tuckpointed elevations hold for decades, but parapets and chimneys want inspection every few years, and box gutters that were relined rather than replaced eventually come due. The good news is that properly maintained St. Louis brick is close to indestructible compared to frame stock — no siding cycles, superior fire ratings, and insurance carriers that generally price masonry construction favorably. Owners who front-loaded the masonry work in the rehab typically see their maintenance line settle well below frame-equivalent portfolios by year three, which quietly improves the very coverage ratio the refinance was underwritten on.

The compounding case

Each cycle recycles roughly the same capital into a door that cash-flows $250–$400/mo after debt service. Two doubles a year on walked blocks is a realistic pace for a disciplined operator — that is four units annually without new capital raises, in a metro where the entry basis forgives learning-curve mistakes.
