Yes, leverage in a property matters, but like most things one can not hold tunnel vision of a single metric and assume knowledge of the whole, it's a spider-web of factors one needs to step back and take into account the relation of each factor upon the other. 

Considering many landlords are distressed like people are also getting about stocks these days I would consider the fact that in regards to landlording in some places the light is at the end of the tunnel so to speak and when you consider if you get a place with an existing tenant even if they immediately stiff you I would consider the realistic timeline to get them out. 

You can literally crawl through one of those tunnels right into Mexico.. lol.  

The whole doom preaching based of tunnel vision of a singular fact removed of the entire eco-system as a whole, this is how we get panicked actions which result in financial loss. 

Another issue I have with central systems, is the ducts are havens for mice and spiders and you name it - hidden tunnels that can get full of dirt, etc.No, it's not normal to charge a tenant for an a/c unit. 

It is refreshing to hear that there is and will be a light at the end of the tunnel.

There is going to be light at the end of the tunnel.

Get though it safely I think there will be a lot of great opportunity at the end of this tunnel.

After two properties are paid off you are now able to see the light at the end of the tunnel.  

While this can be caused by sewer issues at the property level, it is more likely to be caused by the deep tunnel system not being opened in a timely fashion or being overrun.
