Some buyers would rather borrow against a portfolio than sell it. At South Flagler House, here is how that money behaves in the years between the first deposit and the keys.
This page is a framework. Whether the building suits you is a separate conversation. Contact the desk at Miami Dossier for the current position on any building we cover.
A securities-backed line of credit is a revolving loan from a bank or brokerage, secured by an investment account the borrower keeps. The lender sets an advance rate for each kind of holding, so a broad account supports a larger line than one concentrated in a single stock. The rate usually floats over a short-term benchmark, and most lines forbid using the money to buy more securities. Whether a residence deposit is a permitted use is written in the lender’s agreement.

Pre-construction deposits at South Flagler House fall due in stages while the tower rises. A line drawn for each stage stays drawn until closing, so interest runs for years and the collateral has to hold its value the whole time. If markets fall far enough, the lender can call for more collateral or a repayment within days, and can sell holdings if neither arrives. A deposit already paid into escrow cannot be pulled back to meet that call.

The developer and the escrow agent see a wire, not a loan. Contracts still ask where the money came from, and banks apply anti-money-laundering checks to large transfers, so keep the line agreement and each draw record with the deposit receipts for South Flagler House. If the contract carries no financing contingency, a line reduced or closed before closing at South Flagler House does not excuse the closing.
South Flagler House: Park Residences (floors 1 to 3): one- and two-bedroom configurations, about 1,800 to 3,000 square feet of interior space, facing the Norton Sculpture Garden; first-floor homes with private outdoor gardens; approximately 80 percent sold.
At closing a buyer can repay the line from cash, replace it with a mortgage on the residence, or leave it outstanding. A mortgage lender on a residence at South Flagler House counts the line as debt, traces the source of the deposits and may ask for the account statements behind them. Whether the interest is deductible depends on how the borrowed money is traced and used, a question for a tax adviser. The desk keeps the deposit calendar for South Flagler House so draws can be planned against it.
Borrowing keeps the portfolio. It also keeps the portfolio’s risk until the keys.
