I am interested in this topic as well. I am looking at an opportunity in a small rural midwest town. The seller’s asking price is double to triple times the NOI value. There are 13 Speed Queen washers the seller says are bout 15-20 years old. Is there value in these? To establish an offer or just go with the NOI equation? Also, how do you determine how to estimate the cost of the life of the machines to predict getting investment back and putting it into new equipment? I know this is a gamble but the more info the better. I look forward to any responses.
