If you're talking about a cap rate based on the sellers actual expenses and their actual income, then we absolutely paid too much. That is not how properties currently trade though. Forgive me if I'm misunderstanding your question.
At the risk of getting blasted by the many that DO subscribe to that theory, here goes....
We have a yr one operating budget of about $425,000 and their current income is probably around $500,000. So $75k NOI at lets say a 7.5 cap is $1,000,000. No way is it going to sell for that. If I had an accurate picture of the sellers actual expenses, the NOI would be higher, as I know they weren't spending much on it, but they couldn't have been making much profit, so the cap rate would still be really low. Short answer, we bought at a price somewhere between actual value based on actual numbers and what it would be worth when run by a reasonable operator. I would have loved to pay less, but given our experience in the market, it has enough potential to hit the returns we want.
