A $61k chiller assessment I had no way to pass through
This was a 2,900 sf suite in a five-suite medical condo building about a mile from a regional hospital. Bought it at $412k with a solo podiatry practice in place at $26/sf on a modified gross lease with two years left. I liked that the tenant had been in the suite eleven years and had spent his own money on the build-out.
What I did not do was read the condo declaration or ask for a reserve study before I signed the LOI. The building's chiller was original to a 1998 shell. Fourteen months after closing the association voted a $61k special assessment, my share was $17,900, and my lease was modified gross with no expense stop, so every dollar of it stayed with me. There was no operating expense escalation to lean on and no mechanism to bill back a capital item even if there had been one.
The tenant then declined renewal, partly because a hospital-affiliated group offered him space in a newer building with imaging on site. Suite sat 11 months. Re-tenanting a podiatry suite meant plumbing changes for a new specialty, $71k in TI against a five-year term, plus $14k of leasing commission. All in I was about $126k underwater against my original underwriting on a $412k basis. Still own it, still current, but the first five years of that hold are gone.
What I would do differently. Get the declaration, the last three years of association minutes and the reserve study before I spend money on diligence, and price any modified gross medical lease with an expense stop set at actual current-year costs rather than the seller's pro forma.
