Hi Gaston,I am going to assume you are asking for a way to get rental comps other than looking at advertised units or calling other complexes.

These future agreements are complex and down the road; things would be even more complicated both sides change of marital status, children etc. 

And purchase apartment complexes and commercial buildings.

This is my first deal and it’s a quite complex one so I’d like to get some opinions on it.

Some complex things such as 1031 exchange.

Conventional lending guidelines (Fannie/Freddie), will only lend on 'warrantable' complexes.

@Carlos C.Surveillance systems are generally not cost effective for 4 units or less, and as you've discovered, the logistics don't work.If you have a larger complex, then you will likely have a separate meter for general lighting, pumps, etc.

On the other hand, SFH or duplex-4plex do not appeal to me like apartments.An idea came to me ...What if I found an experienced Investor looking to acquire another apartment complex, and I offered them 20k cash to help with the investment.

I also am wagering that if this was not a large complex, the fact that there is a property manager means the landlord is more likely to hire a lawyer.You are correct though, that if this was a rental owned and operated by an individual, in their own name, they could 100% represent themselves.

I should note, I do own other units in the complex so I am very familiar with the rental rates and property structure.
