Property Visit - How often is too often?

[Kevin Forsythe]

Purchased my first rental a few months ago.  When I rented a years ago duplex the owner only came to the house to collect rent.  I personally was OK with that.  I also rented a duplex in the past and the owner knocked on my door every weekend and at least another time during the week.  Averaged a face to face conversation about 6-7 times a month.  I felt that was a little much.  I have been visiting my property about every other weekend to make sure the houses boiler system is purged and do minor yard up keep.  What would this boards opinions be on how often should you visit.  I don't want to be overly aggressive or give the impression that I don't care about the house.

Thank you!
