@Dardine Eduardo SotoTake your time absorbing all of the information.  

This site contains a lot of knowledge to be absorbed, and it can seem overwhelming sometimes with the vast of information on this site.

I am absorbing as much as I can from folks in your world so I can invest with the cash flow from my amazon business.

When you say not contact regarding payoff, I think that means that I can't contact asking THEM to payoff but are you saying can't contact them saying I'll pay off (absorb the delinquent taxes I've paid plus any outstanding from current year) plus offer  to purchase for $300. which around here most would take because they are just letting these remote lands go anyway with access problems, instead of using the $300. to file and foreclose and they get nothing? 

Just reduce rent to the lowest in the market, and absorb less profits.

You would have $300/yr more than what you are after now and you would not have shell shocked your tenant later.These are much smaller numbers which a tenant can absorb over 3 years rather than a 1 time 4.25% hike. 

I have been listening to the podcasts every chance I get absorbing as much information as I can.

In addition, because of the nature of my job I’m able to absorb 9-10 hours a day of podcasts.Can I bother you for book recommendations—especially conceptual?

It takes some thorough due diligence on each asset you're considering buying, to be sure you're getting it at the correct pricing to leave plenty of margin for absorbing a hit. 

I'm currently in the process of buying my first turn key and absorbing advice just like @Daniel Mendez is.
