90% LTC Fix and Flip Loans: How High-Leverage Rehab Financing Really Works

A 90% LTC fix and flip loan means the lender is willing to finance up to 90% of the total project cost, usually defined as purchase plus renovation budget. Borrowers often hear that number and assume it means they can bring almost no cash into the deal. In practice, the lender still checks the file against after-repair value, property risk, marketability, reserves, and borrower strength.

That is why high-LTC offers should be treated as conditional leverage, not automatic leverage. The headline number is only useful if the rest of the project still fits inside the lender’s ARV and risk limits.

On higher-leverage rehab loans, after-repair value often becomes the actual limiting factor. A project may fit at 90% loan-to-cost on paper but still fail the lender’s maximum percentage of ARV once the full acquisition and rehab budget are compared to completed value. That is why aggressive purchase prices and thin spreads tend to collapse under real underwriting even if the borrower is focused on LTC alone.

Borrowers who understand this early underwrite better deals. They stop asking only how much of cost the lender will cover and start asking whether the total capitalization still leaves enough room at completed value.

The borrowers most likely to get strong high-LTC terms usually bring more than enthusiasm. They bring clear comps, a disciplined scope, enough liquidity, and a business plan that still works if the rehab or sale takes longer than expected. Experience helps because lenders trust experienced operators to manage draws, contractors, and timeline drift, but even experienced borrowers get weaker terms on weak projects.

In other words, the best leverage usually goes to the files that look like they do not need to stretch for leverage. That is one of the more counterintuitive truths in private lending.

High leverage can improve capital efficiency, but it also leaves less room for mistakes. If the rehab runs long, resale is slower, or the completed value is softer than expected, the borrower has less equity cushion to absorb the friction. That does not make 90% LTC bad. It just means the project needs more discipline, not less.

Borrowers often make the mistake of comparing offers only by proceeds. A slightly lower leverage structure with cleaner underwriting, faster draws, and a stronger lender relationship can produce better overall project economics than a max-leverage structure that increases risk at every stage.

The right test is whether the deal still looks healthy after you stress it. If the sale takes longer, if the rehab picks up change orders, or if the ARV comes in slightly lower, does the project still make sense? If the answer is yes, high leverage may be a smart tool. If the answer is no, then the borrower is using leverage to hide a weak spread.

The best investors use high-LTC debt strategically. They do not use it to rescue marginal deals. They use it on strong deals where the extra leverage improves return on capital without making the file fragile.
