The more assumptions there are around rehab costs, ARV, timelines, or the exit, the more questions lenders tend to ask. Sometimes it's not that the deal is bad—it's that there's too much uncertainty. What I've seen is that lenders like clarity almost as much as they like strong numbers. A deal with a well-supported budget and a realistic exit plan will often get more traction than a deal with slightly better returns but a lot more unknowns.
