Long-form guides from the underwriting desk.
Plain-English deep dives on how hard money, fix-and-flip, DSCR, and construction loans actually work — written when a question shows up enough times in borrower calls that a single canonical answer beats answering it forty more times by phone.
Dutch vs non-Dutch interest. A borrower’s guide.
Dutch interest charges you for money you have not borrowed yet. Non-Dutch charges only what you have drawn. On a typical fix-and-flip, the difference is one full percentage point. On a 24-month ground-up build, it can be the difference between a profitable project and a marginal one. Worked math, side-by-side cost comparison, and the exact phrases to look for in a term sheet.
