I'll have to check with my banks before I apply, since that might be a deal breaker for me.

Bad Credit, multiple legal cases, bad or no rental history, are all deal breakers.  

But my tenants are pipefitters (they can change a hot water tank), boilermakers (can change a hot water tank with their eyes closed), electricians (can replace a fuse box with a breaker box), electrical crews (can wire a 2 story house for cable tv), scaffold builders (can trim a tree with a pole saw), welders (can replace the factory exhaust with a custom stainless steel exhaust on a riding mower), construction foreman (can add a bathroom counter and vanity).

Look in the electrical panel to see if there are any breaker spaces left.

We also find out about animals (we have a no pet policy) and smoking (we have a no smoking policy) and unauthorized occupants and rule breakers.

Not a deal breaker necessarily, but a risk to be aware of and mitigate.2.

The Fire Service switches the system off as they do with the main house breaker.

Ideally, a fridge in residential unit is on its own 20A circuit meaning a 20A breaker and a single run of 12 gauge conductors to the receptacle for the fridge.

You can also find syndicators on the podcast circuit.

You must be ready to increase you gas pipe by one size,,,if your running 3/4" black pipe get ready to increase to 1".You must run a dedicated 120 volt circuit to the unit.You must ready ready for maintenance ie flushing out the unit with a mild acid solution every 4 to 6 months,,,,If you can handle that,,,,,,the good news is ,,you now have a water heater that will last and last a long time without replacement ,,,,,if youll do the maintenance,,,,no more leaky tanks,,,,,,if your unit fails its usaully an inexpensive electronic component problem ,,easy to change out ,,,,OK gang ,,Im off my soapbox,,,,Best of luck in 2014Dave DoyleLos Angeles
