Five cycles in, leftover capital eats everything, so is it the model or the strategy
Building this out carefully before I buy anything, so forgive the theoretical framing.
Starting capital 60k. Model assumes each deal is all-in at roughly 78% of ARV (purchase, rehab, holding, closing) and refinances at 75% LTV. On a 200k ARV that's 156k in and 150k out, so 6k stuck, plus about 5k of refi closing costs, call it 11k left in the deal.
Here's what my spreadsheet does that I wasn't expecting. Deal one costs me 60k of down payment and rehab cash while it's in flight, and I get back 49k. Deal two I start with 49k, which means either a cheaper property or a partner. By deal four the working capital is under 30k and I'm modeling 140k ARV properties in a submarket I don't actually want to be in.
So either my 78% all-in assumption is too generous, my 11k leave-in is too small, or the strategy as usually described just assumes something I'm not seeing. Which is it? Anyone who's modeled this past three cycles, tell me what you got wrong the first time.
