Sponsor's model says 3 months to contract, their own appendix says 14 months DOM
Looking at a luxury flip as a passive investor. Deck says $2.6M acquisition, $700k renovation budget, $4.2M target resale. Debt at 65 percent of cost, 12 month term with one 6 month extension. Their model runs 5 months of renovation and 3 months to a signed contract, so 8 months, call it 10 with the closing tail. All-in monthly carry they show at $31k.
Only two sales above $4M have closed in that submarket in the past year. Their own market study, buried in the appendix, gives average days on market above $3.5M as 14 months. That directly contradicts the 3 month marketing assumption in the model.
At 14 months instead of 10, that's roughly $124k of extra carry plus extension fees, which moves the equity return from interesting to thin. What I want to know is what an LP can do about that beyond declining. Has anyone seen an interest reserve sized to the appendix number rather than the model number, or a structure where extension period carry comes out of the sponsor's promote?
