How to Set Up a Co-Lender Arrangement for a Seller-Financed Property in Puerto Rico

What is a co-lender arrangement in seller financing?

In a seller-financed sale, the seller acts as the lender: the buyer makes monthly payments directly to the seller instead of to a bank. A co-lender arrangement is the same idea with more than one lender. Two or more people, often family members or business partners, jointly finance the sale and share the incoming payments in proportion to what each one contributed. This is common in Puerto Rico, where family members frequently pool resources to help a relative buy property or to co-invest in a deal.

The mechanics are straightforward, but the documentation is where co-lending succeeds or fails. Because the money flows to multiple people, every payment has to be split correctly, every month, for the life of the loan, and each co-lender has to report their own share of the interest at tax time. Getting the agreement and the tracking right at the start prevents years of confusion later.

How to split ownership percentages and payment rights between co-lenders

The cleanest way to divide a co-lender arrangement is by the share of principal each person funded. If one person put up 60 percent of the financed amount and another put up 40 percent, each monthly payment, both its principal and interest portions, is split 60/40. Alternatively, co-lenders can agree to fixed dollar amounts per payment, though percentage splits scale more naturally as the balance amortizes down.

Whatever method you choose, define it precisely and in one place. The agreement should state each co-lender's percentage or fixed share, how the split applies to both principal and interest, who receives the payment first if the buyer pays a single lump sum, and how a missed or partial payment is allocated among the co-lenders. Ambiguity on any of these points is what later turns a friendly arrangement into a dispute.

Key legal clauses to include in a Puerto Rico co-lender agreement

Beyond the split, a co-lender agreement should address the situations that are easy to ignore at signing and painful later. Include how decisions are made if the buyer wants to modify the loan or pay it off early, what happens if one co-lender wants to sell or assign their share, how the co-lenders handle a default and any foreclosure costs, and what happens to a co-lender's share upon their death, an especially important point in family arrangements.

The underlying note and any security instrument should be drafted so they are consistent with the co-lender agreement, and the whole package should be reviewed by a Puerto Rico attorney before signing. Seller financing touches property law, contract law, and tax law at once, and a co-lender structure adds another layer. This article explains the concepts, but the documents themselves warrant professional review.

Tax reporting: who claims the interest income on 480.7A and 1098?

The borrower's side is simple: the buyer paid interest on a mortgage and is entitled to deduct it, so they receive Form 480.7A (for their Puerto Rico return) and Form 1098 (federal) reflecting the total interest they paid for the year. The borrower does not need to know how the lenders split that interest among themselves.

The lenders' side is where the split matters. Each co-lender reports their own proportional share of the interest received as income on their own tax return, 60 percent of the interest to the 60 percent co-lender, and so on. Because the borrower receives one set of forms for the total interest while the income is divided among several people, accurate per-lender records are essential. Confirm the reporting mechanics with a CPA familiar with Puerto Rico tax law, particularly how the year-end forms are issued when more than one lender is involved.

Tracking co-lender payments, distributions, and tax forms with Lend.

Lend. supports co-lenders natively. You add each co-lender to the mortgage with their percentage or fixed share, and the platform splits every confirmed payment, both principal and interest, according to that share. Co-lenders with a connected payout account can receive their portion automatically, and those without are tracked for manual settlement, with the primary lender able to mark each distribution as settled.

At tax time, the interest split flows through to each party's year-end summary, and the co-lender distributions are reflected in the primary lender's seller summary so the numbers reconcile. Instead of a shared spreadsheet that one person maintains and everyone else has to trust, each co-lender gets clear, consistent records of exactly what they received and what they owe tax on. 60-day free trial, no credit card required.
