There is roof damage, probable damage to the trusses, and the water line busted.

Also just keep in mind characteristics of the property that carriers wish to avoid such as roofs 10+ years old, old/recalled electrical panels, no impact windows etc. 

Was wondering other stuff like property management expense like getting a handyman to fix something or roof changes etc, assuming they are a bit more.

I would rather own 6 to 10 high quality appreciating properties than 20 to 30 lower priced rentals (e.g. replacing all those roofs, HVAC, all the tenants, turnover and property management fees).

What's the condition of major systems like plumbing, electrical, and roofing?

It needed a new kitchen, new bathroom, new floors, a new porch roof, and needed to be totally rewired.   

Obviously there won't be any 100% "safe" tenants, no matter how much vetting you do, a job loss etc. could always happen to anybody... but I feel like having one at all simply shows that they didn't prioritize keeping a roof over their head for one reason or another, among other issues.Everything else from that post, if I am referencing the same one, seems fine to me.

I find it hard for the numbers to work if I only put 3.5% or 5% for down payment as the monthly payment will be through the roof.

Last year on one cabin I had to replace the roof, hvac, & tile shower which came out to $22k.  

I would focus on getting that househack first.You can take advantage of a lower downpayment, get a roof over your head, and an investment property all in one.
