Any practical thoughts, suggestions, or methods to use? 

His son took over his brain surgery practice while Sherry inherited her father's love for real estate. 

Gave me practical experience finding deals (and the tools & techniques involved), working with realtors, lawyers and banks, appraisals, inspections, insurance, property taxes, utilities, closings, HUD statements, etc.Owning a home gave me more practical experience in basic to moderate home repair, dealing with contractors for more complicated issues, capital improvements, insurance claims, "neighbor relations", and many more important aspects involved with owning property.But in addition to buying and owning my own home, I'll say what was equally important to giving me confidence to get started was having a few friends who were already doing what I wanted to do. 

Any advice on study guides or practice texts for the state portion only?

I want to purchase a single family home from a wholesaler and practice the BRRR method.

For me, it was supposed to be for my dental business however for improvements, repairs, investments into equipment etc.But once given, they could not take it back so I could always use it for real estate.55K was offered, but, the rate was too high @ 10% and was on a 3 year amortization. 

That doesn't mean risk doesn't still exist, it just means that you've formulated a plan for minimizing those risks to the extent possible/practical and a game plan for dealing with them if they do come to pass.

However open and honest communication is always good practice.

That's a very common practice.

Meaning does a broker or agent practice what they preach?
