Hiring a bookkeeper to watch the income/expenses is like hiring a gardener to tell you how many roof shingles are laying on the ground after a wind storm instead of hiring a roofer to repair the roof.I recommend that you look for a quality property manager who can maintain the properties and help with the bookkeeping.Start by going to www.narpm.org to search their directory of managers.

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. 

The fact of the matter is you’re claiming to be justified in your defensiveness when you’re not actually a wholesaler… yet anyway… lol if you succeed while doing things properly come back and scream it from the roof tops… While I casually said hiding the fine print from a senile old Man, they don’t have to be in fact senile to pull the wool over their eyes.

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.

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

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

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 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).

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.

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.
