I work as a financial advisor and spend most of my time with clients.

In general I would say that if you are comfortable with bookkeeping, do a good job screening, you have a property in good condition, and you take the time to properly educate your tenant on communication and maintenance procedures, expectations of both parties, and responsibilities, you'll have no problem self managing 1 duplex on your own with very little time dedication.Typically you will probably spend 15-20 min a month on bookkeeping and entering transactions, and that is about it.

The percentage that scale that way are very few and far in between and if you have little saved and 5 kids to spend the good stuff on, you won't have the marketing budget that allows wholesalers to make the good money.

I have the cash to fix it but would rather spend it on my next purchase.My questions to you all are this. 

That's not something I would spend money on for a rental property.

This month I had a tenant turnover so with cleaning and the screening of the new tenants, the old tenant referred the new ones to me, I will spend 3 hours total time on this.

Better just let your property management company deal with it in their system and spend $100 on labor while you sleep peacefully.

This is about the ceiling for what we are looking to spend out of our own pockets. 

I have excess earnings after expenses and my accountant advised to spend this cash on a property, vehicle, or 401k to avoid paying taxes on it.

Spend a day in each area and drive around to learn the areas, the local traditions etc.
