Practicing analyzing RE Deals With Estimates?

[Account Closed]

Hi all!

I'm going into my senior year of high school now and really want to hit the ground running in college and house hack my way through. Problem is, in my amateur attempts to do so, I found that there is so much guess work involved, especially when you're a novice. For example, you have no idea what the closing costs will be, so you plug in an arbitrary number like $2000. You don't know the repairs, so you put say $100 a month. I'm positive this is analysis paralysis, except the kicker is I have no money lol. What should I be doing to get the most accurate "assumptions" for running the numbers? And should the four square method be useful for analyzing a house hack? Is there a better way to do so?

Thanks a ton,

Laila
