The ARV cap is what sizes this loan

Loan-to-cost would have advanced $325,000, but the loan-to-ARV ceiling holds it to $288,400. The difference lands on you as a larger down payment — $65,100 at the table rather than the cost-based figure.

Drawn balance or full loan?

Two structures, the same note rate, the same project.

You have modelled the drawn-balance structure. If the term sheet says interest accrues on the committed amount, use the right-hand number instead.

How this is calculated

The loan is sized twice and the smaller answer wins: loan on cost = purchase × LTC% + rehab × financed% and ARV cap = ARV × LTARV%, then loan = min(loan on cost, ARV cap). Loan-to-cost measures what you are into the property for; loan-to-ARV measures what the lender’s exit is worth. Whichever binds decides your down payment, and when the ARV cap binds the rehab holdback is funded first — a lender will not leave a construction budget half-funded, so the haircut lands on the purchase advance.

Interest is where most calculators go wrong. The rehab half of the loan is a holdback: the lender keeps it and releases it in draws against completed work, so it accrues nothing until it is advanced. This page walks the project a month at a time, releasing the holdback in equal increments over the rehab period and charging month’s interest = drawn balance × rate ÷ 12on that month’s balance. The average balance over a nine-month project with a five-month rehab is below the face amount, and charging the face amount from day one overstates the interest by several percent — more the larger the holdback and the longer it takes to draw. The comparison panel prices both structures on your numbers rather than quoting a rule of thumb, because the gap is a function of the holdback, the draw window and the hold, not a constant.

The alternative structure is real and is the reason for the toggle. A full-loan — or “full boat” — note charges interest on the entire commitment from close, including money still sitting with the lender. The rate sheet looks identical. The comparison panel prices both so you know which one you are being offered before you sign.

The total cost of the money is interest + points + underwriting + draw charges + extension. The effective annualised cost restates that as a rate: total cost ÷ average balance × (12 ÷ months held). Dividing by the average balance rather than the loan amount is the whole point — it asks what the money you actually used cost you, per year, and on a short project that figure runs far above the note rate. It is not an APR in the consumer-lending sense and no lender will quote it; it is the hurdle this borrowing has to clear to be worth doing.

The extension charge applies the moment the payoff month passes the note term, at loan × extension points, charged once. The sensitivity table re-runs the whole calculation at several payoff months so the cost of slipping the schedule is a dollar figure you can see before it happens, which is the only time it is negotiable.

Common questions

  • Why is the effective rate so much higher than the note rate?

    Because points and flat charges are paid once, over a project that lasts months rather than a year, on a balance smaller than the loan. Two points on a nine-month project is not two percent a year — annualised it is closer to three, and it lands on top of the note rate. Add an underwriting charge, four draw inspections and an extension and the gap widens further. The note rate prices the time; everything else prices the transaction, and the transaction does not get cheaper because you finished early.

  • What is the difference between drawn-balance and full-loan interest?

    On a drawn-balance loan, interest accrues only on money that has actually been advanced, so the rehab holdback costs you nothing until the draw is released. On a full-loan loan — sometimes called full-boat or Dutch interest — the lender charges on the entire commitment from the day you close, including money still sitting in their account. Same rate sheet, materially different loan. The toggle on this page prices both, and the difference on a normal rehab runs from a few hundred dollars to several thousand — it grows with the size of the holdback and with how long the draws take, so read the panel rather than a rule of thumb.

  • Which constraint should I expect to bind, cost or ARV?

    It depends on how well you bought. Buy at a real discount with a heavy rehab and loan-to-cost binds, because the total cost is low relative to the finished value. Buy near retail, or run a light cosmetic scope on an expensive house, and the loan-to-ARV ceiling binds instead — the lender caps the whole facility regardless of what you paid, and the shortfall becomes down payment. When the ARV cap binds, the fastest fix is usually a lower purchase price, not a bigger rehab budget.

  • Does the extension charge repeat?

    Sometimes, and that is the question to ask before signing rather than at month nine. Some lenders sell a single extension of three or six months for a point; others charge a point per month past maturity, and a few will not extend at all and expect a payoff or a default rate that runs several points above the note. This calculator models one extension charged once. If your term sheet extends in repeating periods, run the calculator again with the charge multiplied by the number of periods you might need.

  • Should the interest be added to my cash to close?

    No — and this page keeps them separate for that reason. Cash to close is what you wire on the day: down payment, points, underwriting and title. Interest, draw charges and any extension arrive over the following months, either as monthly payments or out of an interest reserve the lender withheld from the loan. Both matter, but they hit at different times and a flip usually fails on the second one, not the first. The bottom row of the cash table adds them up so you can see the whole requirement.

  • Is a rehab holdback the same thing as an interest reserve?

    No. A rehab holdback is your construction budget, released against completed work. An interest reserve is a slice of the loan the lender keeps to pay your own monthly interest, so you make no payments until it runs out. Reserves are convenient and expensive: the reserved amount is borrowed money, it accrues interest of its own, and when it empties the payments start mid-project. This calculator does not model a reserve, so treat its interest line as cash you pay as it accrues.
