Next, I'm fairly handy and do a large number of repairs and maintaence around my own home, but don't have much time or certainly not the time to maintain multiple units.  

@Andrey Y.You’d have to maintain a cellular plan here in the states.

Maintained positive cash flow while improving property.

Your lease does not say they have to maintain a temp.

It is another expensive appliance you will have to maintain and eventually replace, etc so weigh the cost benefit of providing this for your tenants.  

Meanwhile every house we maintain is paid for by someone else, we just have to schedule any necessary maintenance, in an oversimplified end point sort of idea.My wife and I were just talking about how we wished we never sold that property. 

I paid the tax's and she maintained the home..

, maintain caulk in vinyl replacement window exteriors- With elderly cast-iron DWW system in place, ALWAYS be on the alert for comments about foul odors coming from drains/walls -- invaluable indicator that traps are siphoning/leaking out/cast iron is drying out/sewage gas is escaping.- Check for corner tears on screens- Monitor doorways for expanding corner cracks indicating accelerated/new settling.- Repeating @George W.'

In Ontario you do not ever want long term tenants since it will be impossible to maintain rents at market.

When you have an area with to many renters, the values will be low and will only appreciate at a pathetic rate due to the landlord investors who dont want to put enough money into their properties to maintain them and tenants who are to hood.
