Multifamily underwriting software

Multifamily underwriting software, modeled to the studs.

Multifamily underwriting software models an apartment deal from the rent roll up — unit mix, in-place versus market rents, loss-to-lease, renovation premiums, vacancy, and operating expenses — to a levered return an investment committee can defend. Origentic runs it on a deterministic engine for both acquisitions and ground-up development, and it's free to start.

Rent roll to returns in one sitting

Enter unit mix and in-place rents, layer in a loss-to-lease burn-off and renovation premiums, set T-12 operating expenses and growth vectors, and watch levered IRR, equity multiple, and DSCR recompute live as you type.

  • Unit mix with in-place vs. market rents and loss-to-lease
  • Renovation/value-add premiums and lease-up pacing
  • T-12 opex, management fee, reserves, and growth vectors

Acquisition or ground-up development

The same engine underwrites stabilized acquisitions and ground-up development with S-curve construction draws, absorption, and stabilization — so your whole apartment pipeline models consistently.

  • Debt sizing by LTV, LTC, DSCR, and debt yield
  • Preferred equity, junior debt, mid-hold refinance, and reserves
  • GP/LP waterfalls with promote, and exit-cap sensitivity

Committee-ready, every time

Generate a structured investment memo straight from the live model and export the full year-by-year pro forma — revenue, NOI, capital, and levered/unlevered cash flow — to Excel.

Frequently asked questions

What is the best free multifamily underwriting software?
Origentic's free plan is an institutional-grade option for multifamily underwriting: rent rolls, unit mix, loss-to-lease, renovation premiums, debt sizing, and GP/LP waterfalls — the full engine, free for up to 3 active deals — where most comparable tools reserve those features for paid versions.
Can it model value-add and renovations?
Yes. You can model renovation premiums, a loss-to-lease burn-off, lease-up pacing, and interim operating deficits, then see how they flow through to levered IRR and equity multiple.
Does it do ground-up development too?
Yes. The same engine underwrites ground-up multifamily development with S-curve construction draws, absorption, and stabilization alongside stabilized acquisitions.
How does the AI help with a rent roll?
Origentic's glass-box AI extracts unit-level data from a rent roll or T-12 and proposes structured inputs with per-field provenance; a human reviews and approves before anything enters the model.
