I'll spare you all the work that we did and just make this about the numbers.

It is a lot of responsibility and a lot of added stress to your life...if you are willing to sacrifice "going out" and if you are willing to stay in on weekends and dedicate your spare time to this house then no it is not crazy.I am 24 and I am doing this exact thing right living in my own 4-unit complex while working full-time.It is not easy but I am willing to put in the time and make the necessary sacrifices.Good luck and PM me if you have any questions!

This is located in core neighborhood with no spare space for parking.

At that point of time I did not have a full picture of replacement cost (I was assuming it will not be an issue finding spares).I will get a new fridge (this time - low end), but I still struggle to find an answer - how much can I charge my tenants for that?

I hope you all were spared.  

It's also very close to a large community college.20 2/1 units ($800/month)8 1/1 units ($650/month)Laundry room ($800/month according to them although I would expect them to over report this)There's also an office building and some spare land that could be better utilized.Their numbers:Insurance: $9468 (I actually expected this to be lower)Utilities: $22140Property taxes $18600 (I expect this to almost double in the near future)Cable: $5040Repairs and Maintenance: $5620 (This seems laughably low to me, I'd expect 4-5x this)Contract Services: $2400Management: $12000Landscape: $2400Pest Control: $1200It's got a cap rate of 9%.

I did a "similar" thing by purchasing an SFH and renting out my spare rooms.

I only ask bc in my personal opinion I think you should focus on college if that is your plan and make the best of that while your there and at the same time keep learning about RE investing in your spare time.
