Multifamily & Mixed-Use
Development management and owner's representation for rental communities and mixed-use projects with ground-floor retail, from entitlement through lease-up.
In multifamily, the return is decided in the buyout.
A rental community is underwritten on a thin spread: rents and occupancy on one side; land, hard cost, financing, and time on the other. Most of what moves that spread is fixed early, in the design decisions that set the podium and the parking, in the contract terms and bid leveling that set the buyout, and in the first months of construction, when the change-order log starts to grow. Aventra works only for the owner, and brings to that seat the experience of having priced, built, and delivered Class A rental towers and mixed-use communities across Miami-Dade County.
Developers who need senior development capacity, family offices and private capital entering ground-up multifamily, equity partners and lenders, and landowners weighing rental housing.
Thin margin and high carry, ground-floor retail as a second product, a podium that sets the budget, jurisdiction-specific approvals including the Live Local Act, and lease-up that starts before completion.
Feasibility, entitlements, design management, procurement and buyout, budget and contingency control, retail coordination, and lease-up readiness, as development manager or owner's representative.
Fees are a fixed fee or a monthly retainer for a defined scope and duration, quoted in writing before the work starts. Aventra takes no percentage of construction cost and no fee from any contractor, vendor, or consultant on the project.
280 units under Aventra development management today: Banyan House and Addison Landing, with about 22,500 square feet of ground-floor retail between them.
One conversation about the site, the program, and the pro forma. No obligation.
Who we serve
- Developers and sponsors who need senior development management capacity for a project their own team cannot absorb, without adding permanent staff.
- Family offices and private capital entering ground-up multifamily, who want a fee developer accountable to them, with ownership and economics staying with the capital.
- Equity partners who want independent eyes on a sponsor's budget, schedule, and draws.
- Lenders who need construction monitoring, draw review, and cost-to-complete analysis.
- Landowners, including commercial property owners and institutions, weighing rental housing on land they already hold.
Why multifamily and mixed-use projects are different
- Thin margin, high carry. Construction interest, insurance, and the date the first units lease move the return more than almost any line item. A month of delay is paid for twice: once in carry, and again in rent not collected.
- Ground-floor retail is a second product. Shell or vanilla-box delivery, grease and exhaust routing, utility separation, storefront, and tenant improvement allowances have to be decided before the space is leased, and retail leasing runs on its own clock.
- The podium sets the budget. Structured parking is the most expensive and least visible part of the building. Parking ratios, ramp geometry, and the transfer between the podium and the residential floors lock in cost early.
- Approvals vary by jurisdiction. The City of Miami, unincorporated Miami-Dade, and villages such as Palmetto Bay each run their own zoning, design review, and permitting process. Florida's Live Local Act has opened a separate path for rental housing, with a workforce set-aside, on commercial and mixed-use land.
- Hurricane-grade code and cost. Miami-Dade and Broward sit in the High-Velocity Hurricane Zone, with product approvals for windows, storefront, and roofing, and builder's risk and wind coverage that belong in the pro forma from the start.
- Lease-up starts before completion. Amenities, model units, and the leasing office have to be ready early, and temporary certificates of occupancy by floor or phase decide when revenue begins.
What we do for multifamily owners
- Site, program, and feasibility: unit count and mix, parking and retail program, and order-of-magnitude cost and schedule, tested against the pro forma before the land closes.
- Entitlements and approvals: zoning strategy, site plan and design review, and permitting, including Live Local Act and workforce housing pathways where they apply.
- Procurement and buyout: delivery method, contractor prequalification, bid leveling, GMP negotiation, and a buyout reviewed line by line.
- Budget, schedule, and contingency control: one budget of record, owner contingency tracked against the risk log, and a schedule tied to the loan and the lease-up.
- Construction oversight: change order review, quality, and independent monthly reporting in The Aventra Owner's Report.
- Ground-floor retail coordination: shell and vanilla-box scope, landlord work, tenant improvement allowances, and coordination with the owner's leasing broker, so the space is ready for the tenants it is marketed to.
- Lease-up readiness and closeout: amenity and model-unit FF&E, temporary certificates of occupancy by phase, turnover, closeout documents, and warranty.
- Monitoring, due diligence, and project rescue: independent construction monitoring for lenders and equity partners, due diligence on projects under construction or recently completed, and recovery of projects that have lost budget or schedule. Construction monitoring for lenders and investors.

Every engagement begins with one conversation and, where it helps, a fixed-scope review before any larger commitment. How an engagement begins.
Two products on one budget. Delivered on the owner's terms.
The contractor protects its margin. The retail broker protects the lease. The lender protects its capital. Aventra protects the owner: the budget, the schedule, and the day the first residents move in.
Multifamily projects, answered plainly.
What does a development manager do on a multifamily project that the general contractor does not?
The general contractor builds what is drawn, for the contract price, and manages its own subcontractors. A development manager works for the owner across everything around the construction contract: the program, the design team, entitlements, the budget of record, lender and equity reporting, the retail, and lease-up readiness. On the construction side, we are the owner's check on the contractor: the buyout, the change orders, and the pay applications.
Can Aventra represent an equity partner or lender on a project someone else is developing?
Yes. We provide independent monitoring for equity partners and lenders: budget and schedule validation at closing, monthly site observation, pay application and draw review, change order review, and cost-to-complete analysis, reported to the party that engaged us.
When should an owner bring Aventra in?
Ideally before the land closes. Unit mix, parking, the retail program, and the entitlement strategy are set at the very beginning, and that is where the underwriting is easiest to protect. We are also engaged after a contractor is selected, and mid-project when cost or schedule is drifting.
How do you handle the ground-floor retail?
As its own product, from the first design meeting. The shell scope, utility and exhaust provisions, storefront, and landlord work are set with the owner's leasing broker so the space can be marketed to the tenants the pro forma assumes, and tenant improvement allowances are carried in the budget from the start.
Do you work on Live Local Act and workforce housing projects?
Yes. Florida's Live Local Act allows rental housing on land zoned for commercial, industrial, or mixed use, provided a share of the units remains affordable for a fixed period. We help owners test whether a site qualifies, what the set-aside does to the pro forma, and how the approval path compares with a conventional rezoning. The legal analysis stays with the owner's land use counsel.
Do you work outside South Florida?
Our home markets are South Florida and the Caribbean. We take on select multifamily and mixed-use engagements elsewhere in the United States where the project calls for this experience.
