So as many of you know, I am so so close now to getting out the starting blocks (3 weeks yesterday till i'm fixed and then it's no holds barred). As most of you also probably know I have been playing around in Excel for a VERY long time building a model I can use for investment analysis. I have set it up so I can plug in certain variables and see it change instantly. For example: I have my yield set to 4.55%, my tax set to 33% and my costs set to 17.5%. This is where I get confused. I mean my yield I manipulate to see what yield I "need" to get my figures around where I want them so i understand that and my tax.... well not much I can do about that but my costs. This is to show the cost of a PM, repairs, vacated periods and any other fees that come with owning an IP. The problem is I don't and have never owned an IP so I am sort of pulling that number out of my bum. For those of you who have done similar analysis. What is a percentage that you generally deem as an acceptable amount to budget for the cost of owning an IP? Once I have this I think I have the full picture, I might upload a copy of my model and get you guys to check it out for me, always good to have experienced eyes cast over things like this.
