The Private Lender LOS Built From the Ground Up With AI
Most loan origination systems were built for banks and mortgage companies. Private lenders are an afterthought — shoehorned into workflows designed for conforming loans. Lend Engine is different: it was built exclusively for private credit, from day one, with AI at the core.
What Makes a Private Lender LOS Different
Private lending does not conform to agency guidelines. There is no standard income ratio, no FNMA approval matrix, no uniform underwriting handbook. Every lender defines their own criteria: their LTV limits, their minimum DSCR, their acceptable property types, their geographic concentration limits, their borrower experience requirements.
Legacy LOS platforms cannot handle this natively. They were engineered around a world where the rules are predetermined — by FNMA, by FHA, by the secondary market. Their criteria engines are rigid, their workflows assume a conforming loan process, and their underwriting logic is built around borrower income and agency guidelines rather than collateral value and deal structure.
Private lenders who try to use these platforms spend more time fighting the software than using it. They build workarounds. They export to Excel. They maintain parallel systems. They hire additional staff to manage the manual overhead that should not exist.
Lend Engine was built for a different operating assumption: that underwriting criteria should be fully configurable, that asset-based analysis should be native, that deal structures should be flexible, and that the platform should accelerate the team rather than constrain it. Every feature in Lend Engine was designed with this in mind.

Frequently Asked Questions
Common questions from private lenders evaluating Lend Engine as their LOS.
What is a private lender LOS?
A private lender LOS (loan origination system) is software that manages the full origination workflow for non-bank, non-agency lenders — from application intake and underwriting through term sheet issuance and closing. Unlike conventional mortgage LOS platforms built around agency guidelines, a private lender LOS must support asset-based underwriting, custom criteria, flexible deal structures, and loan types like hard money, DSCR, fix and flip, bridge, and construction. Lend Engine was built exclusively for this market, from day one.
How is Lend Engine different from traditional loan origination software?
Traditional LOS platforms were built for bank and mortgage company workflows — conforming loans, income-based underwriting, agency guidelines, and 30-to-60-day timelines. Private lenders are an afterthought in these platforms, typically shoehorned into workflows designed for a completely different business model. Lend Engine was built exclusively for private credit from day one, with AI-native underwriting, ARV and AVM analysis, draw management, custom criteria enforcement, and workflows optimized for the 7-to-30-day timelines that define private lending.
Can I customize my underwriting criteria in Lend Engine?
Yes — fully. Lend Engine's criteria engine lets you define LTV, LTC, DSCR, ARV, and loan-size limits at any level of granularity: by loan program, property type, state, county, or MSA. Rules are enforced automatically at the underwriting stage, flagging any deal that falls outside your box before it advances. You can configure different criteria for each loan program independently — your hard money program, your DSCR program, and your construction program can each have entirely separate underwriting rules — without any coding or vendor involvement.
How long does it take to set up Lend Engine?
Most lenders are fully operational on Lend Engine within 30 minutes of account creation. The onboarding flow guides you through configuring your loan programs, underwriting criteria, and branding in a structured sequence. If you have existing loan data to migrate from a spreadsheet or another system, the Lend Engine team provides a structured data migration process that is typically completed within one business day for most portfolios — not the weeks-long implementation projects required by legacy enterprise LOS platforms.
Does Lend Engine work for both hard money and DSCR lenders?
Yes. Lend Engine is designed to support multiple loan programs on a single platform, and many of our customers originate both short-term bridge and hard money loans alongside longer-term DSCR rental products. Each program has its own criteria, underwriting workflow, and term sheet template — with program-specific AI analysis (ARV-based for hard money, cash-flow-based for DSCR) applied automatically based on the loan type submitted. All programs share unified pipeline visibility, reporting, and borrower management within a single dashboard.
