Buy Here Pay Here and Auto Finance Company Capital: Portfolio Lines and Receivables Funding

By MercFinancial · Published 2026-10-21

Buy here pay here dealers and their finance companies are capitalized with a floor plan on inventory, a portfolio line against installment contracts and bulk contract sales. What lenders underwrite and how the three lines fit together.

A buy here pay here dealer and its related finance company are capitalized with three lines: a floor plan for the vehicles on the lot, a portfolio line against the retail installment contracts, and the sale of contracts in bulk or on a forward-flow basis, because the real business is the consumer receivables the dealer carries, and that is what lenders underwrite. Banks and several large online lenders decline both halves of the operation, the dealer on restricted-industry lists and the finance company under the SBA's exclusion of lending businesses and most bank credit policies.

This guide explains why BHPH is two businesses that confuse general lenders, each of the three capital lines and who offers it, the advance rates and static-pool metrics portfolio lenders size on, the servicing and repossession operations they inspect, a hypothetical portfolio line, and the mistakes that get dealer files declined. It closes with how MercFinancial places the request.

Every car a buy here pay here dealer sells turns cash into a promise, and the portfolio line is what turns the promise back.

Why BHPH is two businesses, and why that confuses lenders

A franchise dealer sells a car and is paid by a bank within days. A buy here pay here dealer sells a car and becomes the bank: the sale produces a retail installment contract that pays weekly or biweekly over a couple of years, and the dealer's cash is tied up in that contract from the day the customer drives off. Many dealers move the contracts into a related finance company, so the dealership sells cars and the finance company holds paper. A general lender looking at the combined file sees a used car dealer, which several large online lenders name on restricted lists, and a finance company, which bank policy and the SBA's exclusion of businesses primarily engaged in lending under 13 CFR 120.110(b) both shut out.

The customer base is subprime by design, the collateral is a depreciating vehicle, and every month of growth consumes more cash than it returns until the portfolio is large enough to pay for itself. That is a profile banks are not built to underwrite. It is exactly what portfolio lenders are built to underwrite, which is the premise of this guide and of the wider series on consumer finance company funding. The dealership side, including inventory and real estate, is covered under auto dealer funding.

The three capital lines of a BHPH operation

The lines interact. A floor plan lender wants its unit paid off when the car sells, which the sale does not produce in cash, so the portfolio line draws against the new contract to pay the curtailment. A dealer that sells contracts in bulk gets cash and gives up yield, and it also gives up the static pool history a portfolio lender will later want to see. Most operations run a floor plan and a portfolio line together, and turn to bulk sales when growth runs ahead of the line's commitment. The stack for a finance company that holds its paper is described in financing for consumer finance companies.

Advance rates, static pools and the metrics lenders underwrite

A portfolio lender advances against eligible contracts, not the whole book. Eligibility usually excludes contracts beyond a days-past-due cutoff, contracts extended more than a set number of times, contracts over a maximum term or amount, and contracts where the amount financed exceeds a cap relative to the vehicle's value. The advance rate on what remains is a fraction of principal, commonly lower for a new or dealer-originated book and higher for a seasoned book with proven losses, and the lender re-sizes it each month from the borrowing base certificate. The mechanics are the same as in the guide to portfolio financing for installment lenders, with vehicles added as collateral behind the contracts.

• Static pool losses by month of origination, the single most important report in the file.
• Repossession rate, days to repossess, and recovery at auction as a share of the balance.
• First-payment and early-payment default, which expose underwriting more than any ratio.
• Delinquency by bucket, thirty and sixty days, against the covenant the facility carries.
• Down payment collected and term, which set how much is lost when a contract fails.
• Payment frequency and collection method, in person, by bank draft or by card, and the use of GPS or starter-interrupt devices where state law permits and disclosures are made.
• Portfolio yield after losses and servicing cost, the number the whole operation lives on.

Servicing and repossession: the operations a lender inspects

A hypothetical portfolio line, and the mistakes that get files declined

Illustrative example: a hypothetical BHPH finance company carries $2,000,000 of contracts, of which $1,700,000 are eligible after the past-due, extension and advance-to-value cutoffs. At an illustrative 60 percent advance, availability is $1,020,000, and each new contract adds to it at the same rate while each curtailment on the floor plan draws against it. The figures are invented to show the mechanics and are not any lender's terms.

The mistakes are familiar to every portfolio lender. The dealer's books and the finance company's books mixed into one set of statements. No static pool report, because nobody set the system up to produce one. Extensions used to keep delinquency under the covenant. Floor plan curtailments missed because the sale produced paper instead of cash. Contracts sold in bulk without keeping the performance data. GPS devices used without the disclosures state law requires. Applications to online lenders that list dealers and lenders as restricted. And a merchant cash advance taken on the dealership to cover a curtailment, which puts daily debits on the account a portfolio lender expects to control. The merchant cash advance red flags apply here with extra force, and the wider set of business funding programs is better entered with the books already separated.

Where MercFinancial fits

MercFinancial is a commercial funding brokerage in Houston, not a lender, and it does not run a BHPH program. It reads the file first: the contract portfolio and static pools, the floor plan, the servicing data and the owner's credit. From more than 160 wholesale and institutional funding sources, it identifies the ones whose credit policy allows a BHPH operation and the line requested, places one file with those sources, and compares the offers. Availability depends on the funding source, and when the portfolio is too young for a line a specialist says so and points to the floor plan or the real estate instead. Stephanie, the AI lending assistant, pre-qualifies in two to three minutes with a soft credit pull, and a free 30-minute call is the next step.

Frequently Asked Questions

How do buy here pay here dealers finance their inventory?

With a floor plan line from a floor plan company or a specialty auto lender, which advances against each vehicle from auction to sale and requires a curtailment or payoff after a set period, commonly 60 to 120 days. Because a BHPH sale produces a contract rather than cash, the payoff usually comes from the portfolio line drawing against the new contract, which is why the two lines are arranged together.

What is a portfolio line for a BHPH dealer?

A revolving line secured by the retail installment contracts, sized monthly by a borrowing base of eligible contracts times an advance rate. Lender-finance firms, specialty auto lenders and a few bank dealer-finance units offer it, underwritten on static pool losses, repossession and recovery data, delinquency and extension practice. It funds the cash a dealer gives up each time it sells a car on its own paper.

Can a buy here pay here dealer get an SBA loan?

The dealership can apply, because new and used car dealers are not excluded by the SBA's eligibility rule, but the related finance company cannot, since businesses primarily engaged in lending are ineligible under 13 CFR 120.110(b). In practice many SBA lenders pass on BHPH because the dealership's value sits in the finance company's paper, so the request is placed with lenders whose policy allows it.

What advance rate do lenders give on BHPH contracts?

A fraction of eligible principal that the lender negotiates from the book's seasoning, static pool losses, recovery rates and the dealer's servicing, and that it recalculates each month. New or dealer-originated books get lower advances, seasoned books with proven losses get higher ones, and contracts past the cutoff, over-extended or over the advance-to-value cap drop out of the base entirely.

Should a BHPH dealer sell contracts or borrow against them?

Borrowing keeps the yield and builds the static pool history that future lenders will underwrite, at the cost of covenants, reporting and a field exam. Selling in bulk brings cash sooner and removes the servicing burden, at a discount to principal and with the data leaving with the paper. Most dealers borrow against the book and sell only when growth outruns the line's commitment.
