That way I could incorporate possible monthly income generated into my income.

Such a poor-performing property manager will result in more frequent tenant turns, more frequent maintenance, which generates more income for the property manager.Another claimed advantage is that there is already a tenant in place.

To generate leads it typically takes real money.

I have thought about that question and my end goal is to build a big enough business where I no longer have to work (outside of real estate, of course) and I can financially support me and my family with income generated from the properties that I'd own. 

I am just a somewhat random internet guy.... :)

If they cannot generate income from it they may say "No." 

This is why we use whole house or stationary gas generators for backup.Natural Gas is best.

and you didn't have the generator fixed or replaced. 

In my limited experience I would say that if you go virtual in a different market (say a smaller city with lower priced homes) you'll generate more leads, but you may struggle with disposition as there is less Investor activity from your potential end buyers (Small,Med, and Large Flippers, Institutional/Hedge Fund Buyers, Turnkey Operators..etc) On the flip side if you stay in the more competitive market it will be a grind to get those first few leads and to secure a contract but your odds of not being able to dispo it should drastically decrease (Assuming you have a discounted deal in the right area) and that check should be NICE. 

But if you get to the point where you're negotiating, then you're in a good spot.You can use list source to find and generate list but just know, mailing has 1% response rate.
