This question is for the experienced investors...some of which have 5+ properties (including interstate). Just wondering, particularly for those who buy houses what is the time and cost involved in managing your portfolio each year? I am re-considering my long term strategy of holding multiple properties given strong time constraints (soon 2 kids under 2). I'd also like to get a better estimate in particular of "maintenance" costs for holding a house, particularly interstate where someone else has to attend to every blocked drain, roof leak etc. Thanks!
