The best value-add deals die in a tangle of spreadsheets.
A block split or a BRR has a dozen moving parts — day-one value, refurb draws, bridging, refinance at 75%, ICR, the exit. Model it by hand and you’re an evening deep before you even know if it stacks. Get one assumption wrong and a “great deal” becomes a money pit.
PropStack shapes the whole deal — buy to exit — in minutes.
Everything you need to judge a deal — nothing you don’t.
