But as I've mentioned, I've never seen anything perform as it has from its beginnings in 2009. 

I have some wholesalers that don't even charge me any deposit because I always perform when I say I want it.

In my third year of college working towards a a bachelors in Business Management, and I have no debt and 7k dollars in the bank.

I would put it into multifamily.  10% COC is unrealistic here in Central Oregon in my opinion or at least my abilities, but I think you could by something with under performing rents and then over the coarse of a year or two raise them so you are getting 10% on your 450k,  That would be using leverage.  

You need to perform a credit, criminal & eviction check on every applicant.

From there, I would filter down to the most motivated people who would take a very low price, perform a title search to check for liens and title issues, get a contractor to give a more accurate estimate for repairs and use that to refine my calculations, get the contract and necessary forms signed to secure the property and then finally market it to my buyers. 

I just closed on my first multi family building in September and love how it’s been performing.

Also, can I do this through an LLC or would that hinder my ability to get the best outcome since I would only be a one third partner in the LLC. 

I also think it makes sense to sell sometimes if a property is performing well, but takes up your valuable time.

Get good at ball parking estimates, place an offer if they accept then use your inspection period to perform the in depth report.
