While you actually may be just opening from one rabbit hole of headache from left pocket to  another rabbit hole headache into the right pocket, all these investment has known and unknown risk which could eat  our soul and financial if we don't understand of what we're doing.this is why in biggerpocket i no longer curious or think if someone has 9999 doort.

See my review on the above BP thread.There is NO goose laying golden eggs!!!   

Condos will eat you alive.Is it warrantable? 

At a novice level many eggs in one basket is not a bad thing.

It gave us a really nice nest egg to roll into our 16-unit apartment complex that we own and manage now. 

If you have "high-end" units where you feel a disposal is a MUST for your prospective tenants then perhaps it is worth it.One way to keep the costs down is to inform the tenant that if they jamb the disposal or if a foreign object is found at time of service then they will eat the cost.

No need to test just be careful with it (don't eat, wear respirators, clean up thoroughly, have drop cloths/paper down, and disclose it to buyers). 

Don't people need to eat?

Passive income was one of the biggest reasons for my second acquisition, I am trying to build a nest egg for my future self.
