A while back I was thinking it would be good to get more commercial work as well.
I recently bid an HOA and an apartment complex where I was able to find out what the other bids were.
Seems like the other bids were too competitive. I ended up shrugging my shoulders and putting in my normal bid -10%. That bid still ended up being 20 - 30% higher then there cheapest bid.
I realized I only bid two accounts so far but I'm pretty sure it's not worth it for me to pursue HOA's or Apartments. I'm going to stick to residential, retail, and small businesses for now. Maybe business parks in the future, not sure what that markets like either?
