I have a video on how I do this on my Youtube Channel :) 

I also watched Chad Carson's videos about being a small but might investor. 

The adult child would not likely be able to afford to purchase in the neighborhood where the parents live.

I actually made a YouTube video answering this question in greater depth, but I'll summarize here. 

Google docs, videos)*This is for direct to owner/off market deals #AskBP

My advice to them is you really need to know construction and walk properties (not just look at videos and photos), know the area, have an unbiased local investor do a walk through (if you can't fly there in person), and how to read inspection reports and get a sewer line scope. 

I have watched many of his videos & he contradicts himself a lot & is unauthentic.

Have the agent video everything, just in case tenant is there and causes a scene or refuses access.You will either get the work done or have a video supporting your eviction.

Any advice, suggestions, books, videos or discussions are welcomed and greatly appreciated.

Can anyone suggest training videos, books, or other resources that would help educate me on the topic?
