The Bank of Mom and Dad gets a ledger

⚡ The Signal

The largest informal mortgage lender in America does not have a banking charter, an NMLS ID, or a compliance department. It is the Bank of Mom and Dad.

With home prices hovering near historic peaks and affordability squeezed across the board, down payment assistance from relatives has shifted from a rare privilege to an essential prerequisite. As CNBC recently highlighted, more buyers are relying on family help for down payments than ever before. Meanwhile, tighter credit standards make it difficult even for high earners and buyers with gig-economy incomes to satisfy strict loan-to-value ratios without outside capital.

Yet consumer lending infrastructure still handles family capital like an awkward, manual afterthought: a blunt PDF gift letter signed under penalty of perjury, followed by weeks of anxious underwriting review.

🚧 The Problem

When parents supply tens or hundreds of thousands of dollars to help their children secure a home, the current mortgage system offers only two terrible options:

1. The Gift Letter Fiction: Underwriters require parents to sign Fannie Mae or Freddie Mac gift affidavits stating the funds never need to be repaid. This eliminates legal recourse for the parents, risks triggering confusing IRS Form 709 gift tax obligations, and creates bitter estate disputes among siblings later on.
2. The Informal Private Loan: If families attempt an informal repayment agreement, underwriters treat it as undisclosed secondary debt, blowing up the borrower's debt-to-income ratio and often killing the loan entirely during final verification.

Neither option accommodates modern family finance. Parents often want a middle path: a legally protected shared-equity stake, an interest-only second note pegged to the IRS Applicable Federal Rate (AFR), or simply clean tax reporting that ensures sibling fairness when the estate eventually settles.

🚀 The Solution

Enter Vect, a fintech workflow platform that transforms informal family down payment contributions into institutional-grade, mortgage-compliant shared equity agreements or private promissory notes in under 15 minutes.

Vect provides a streamlined digital flow where home buyers and their families align on capital terms before underwriting begins. The platform automatically generates agency-compliant gift affidavits, IRS-compliant intrafamily notes, and state-specific title recording packages. Once the home closes, Vect automates the ongoing financial relationship—handling recurring ACH disbursements, tracking equity yields, and auto-generating annual IRS Form 1099-INT and Form 709 filings.

Instead of an uncomfortable conversation over the kitchen table followed by panic during underwriting, family assistance becomes a clean, structured financial instrument.

💰 The Business Case

Revenue Model

Vect monetizes across the lifecycle of the transaction through transactional documentation, recurring servicing, and B2B SaaS:

• Document & Compliance Pack ($499 one-time): Paid at closing for generating Fannie/Freddie gift affidavits, state-specific promissory notes, and automated county recording packages.
• Private Note Servicing ($19/month): Recurring fee paid by the family for automated split-ACH payments, annual interest statements, amortization tracking, and automated year-end tax documentation.
• Mortgage Broker White-Label Portal ($99/month): B2B SaaS tier allowing loan officers and independent mortgage brokers to invite clients, expedite seasoning audits, and eliminate underwriting delays on unseasoned funds.

Go-To-Market

Vect relies on a distribution flywheel anchored in loan officer utility and high-intent search:

• Free Underwriting Toolkit for Loan Officers: Mortgage brokers frequently see closings stalled by unseasoned family wire transfers. Vect offers loan officers a free portal link that diagnoses seasoning issues and produces underwriter-ready documentation on demand.
• Engineering-as-Marketing Tax Engine: A free, public intrafamily loan calculator that helps parents evaluate minimum required AFR rates, Form 709 gift tax thresholds, and estate tax tradeoffs.
• Programmatic Regulatory SEO: Dynamic landing pages indexing monthly IRS Applicable Federal Rates paired with state-by-state second-lien guidelines, capturing families actively researching private lending rules.

⚔️ The Moat

Traditional legal platforms like LegalZoom offer generic contracts that fail conforming mortgage underwriting checks. Private lending startups like National Family Mortgage or Pigeon Loans focus narrowly on peer-to-peer promissory notes without building deep integrations into agency mortgage origination workflows, while equity co-investors like Nestment cater primarily to co-buying syndicates rather than intra-family wealth transfers.

Vect's unfair advantage is multi-decade administrative lock-in. When a family establishes a 15- or 30-year shared-equity arrangement or private second note through Vect, the ongoing tax reporting, title lien compliance, and monthly ACH servicing remain rooted on the platform for the entire duration of homeownership. The switching cost is extraordinarily high because unwinding the arrangement requires renegotiating both legal title and family dynamics.

⏳ Why Now

First-time homebuyer affordability remains near generational lows, turning family capital from an occasional luxury into an essential stepping stone. At the same time, generational attitudes toward wealth are changing rapidly. As CNBC observed regarding family dynamics, next-generation family managers are taking more structured, active postures with capital—a mindset trickling down to everyday households that want their family gifts to function with professional transparency rather than casual ambiguity.

Parents want to protect their life savings, mortgage lenders want ironclad paperwork, and adult children want to get their foot on the property ladder. Vect provides the infrastructure that satisfies all three.

🛠️ Builder's Corner

To build an MVP of this concept, speed to compliance and data integrity are the primary engineering hurdles:

• Application Core: A Next.js App Router front end deployed on Vercel delivers rapid, authenticated client portals. Supabase handles the underlying data layer, where PostgreSQL Row Level Security enforces strict data isolation between borrowers, parents, and lending partners.
• Identity & Legal Packaging: Clerk manages zero-friction authentication across multiple parties signing from different households. For legal instrument generation, a server-side document rendering library like react-pdf creates standardized Fannie Mae and Freddie Mac gift affidavits and promissory notes, paired with OpenSign or DocuSign webhooks for cryptographic e-signatures.
• Payment & Tax Pipeline: Stripe Connect Custom accounts handle borrower ACH debits, fee splits, and disbursements back to the parents without holding client funds directly on your balance sheet, while scheduled worker jobs track year-to-date interest splits to generate end-of-year tax statements.

This architecture lets an indie team ship a compliant pilot in weeks, validating demand with local mortgage brokerages before expanding to automated county title recording integrations.
