I recently contracted on a 5 unit multi family apartment complex.

You'll also want to account for your exterior maintenance for lawn and landscaping.If there are any common areas within the complex (i.e a shared entry, hallway with mailboxes, laundry room, etc.) you'll also need to factor in utility expenses for electric and likely gas.Even without all the increases, the property is too much and/or the rents are too low in order to obtain a good return. 

I grew up in a Condo which we now own and I’ve been thinking about buying a couple units within our complex area.

*Thought about small multi-family but seems more complex to down the line maybe.

So, I can renovate any property in the US to move in condition by doing a cosmetic upgrade for $XX depending on the size of the property.This is just step one to get to an offer stage...you'll need to bust *** in due diligence to confirm your assumptions...a great agent can be your best asset here...or your contractor network.Unfortunately, the real solution is a wildly complex algorithm that will only get you marginally better results...remember, acquire properties by going through phases...phase 1 is getting comfortable with an offer based on what you know after the first filter...entering due diligence is where the real work starts. 

Once I have the basics down, I’ll then begin to look into more complex and intricate properties.What are some of the major issues with investing in Turnkey properties?

When I bought my first park, I was pretty confident it was going to be just another version of an apartment complex. 

I reached out to one and the rate was $175 for half an hour and $300 for a full hour and $500 - $750 depending on how complex/inclusive the lease agreement will be.

- This is a very complex question that takes a long time to understand.

In a large complex this would not apply, however, in a small single family rental, would you allow the tenant to have access to the security feed?
