Project Reviews for Residential Infill Builders.
Merchant residential builders run a different business than large production homebuilders and a different business than institutional developers. You buy a lot, build one to a handful of units, sell them, and put the capital back to work.
Bivvit reviews your recent completed infill projects and shows what keeps happening across them: where the money went, how long it was there, what the timing cost you, and what those projects are telling you about the next one.

An infill project is a small development deal, not just a job
A job cost report covers construction. An infill project's result also depends on land basis, financing, carry, capital duration and sellout. Bivvit reviews all of it together.
Your free Project Snapshot starts with completed-project records so costs, timing, carry, cash and profit can be reviewed side by side.
- Land basis
What you paid for the lot sets the ceiling on the deal. It belongs in project profit and outside your construction cost metrics, so hard cost per square foot stays comparable across sites.
- Hard costs
Sitework, foundation, framing, envelope, mechanicals and finishes — reviewed against the project's own budget so a category that ran high is visible instead of buried in the total.
- Soft costs
Design, permitting, engineering, utilities, impact fees, insurance and overhead allocation. Soft costs drift quietly and rarely show up in a single job cost report as a trend.
- Financing and carry
Interest, points and fees accumulate with time. Carry during construction and carry during sellout are two different problems with two different fixes.
- Builder equity
How much of your own cash the project required, when it went in, and when it came back out at closing.
- Cost per square foot
Hard cost per SF and total project cost per SF, always paired with product type, unit count, project size and construction period.
- Construction duration
Permit to certificate of occupancy. Duration is a cost: it shows up in carry, in market exposure and in the lot you could not buy yet.
- Sellout duration
List to close, per unit. On a multi-unit infill project, sellout often controls the return more than build speed does.
- Sales result
Actual closings against underwritten pricing, plus commissions, closing costs and concessions.
- Profit and margin
Profit per project, profit per dollar of equity, and profit per month of capital tied up are three different answers to “was this a good deal?”
Built for how infill builders actually build
Townhomes
Multi-unit fee-simple or condo townhome projects where sellout timing across units drives the return.
Single-family (SFR)
Detached spec homes where finish level and one closing decide the outcome.
SFR + ADU / DADU
A primary house plus an attached or detached accessory unit — two products, one site, one budget.
Cottage housing
Small-footprint clustered units with shared sitework and a distinct cost per SF profile.
Small-lot development
Tight sites where sitework, utilities and access often decide whether the deal works.
Missing-middle housing
Duplex through small multiplex infill delivered by merchant builders, not institutional developers.
The questions a completed infill project can finally answer
- Which cost categories actually caused the budget miss on this project?
- What did the project cost per square foot, hard cost and all in?
- How much of the total cost was land, hard cost, soft cost and financing?
- How long was my own cash in the deal, and what did it earn while it was there?
- Did construction finish on time but sellout run long — or the other way around?
- Was contingency carried, spent, or never there in the first place?
- What should the next lot's budget look like because of what this project taught me?
