I'm also reaching out to a few agents now to see whom best fits my investing approach, if you don't mind me asking which realtor you used (totally cool if not)?

No disrespect to them but in a changing market, I can't help but to notice them overlooking the long term perspective...Of course we all want to win and I approach it that way when dealing with wholesalers but most of my deals have NOT been from wholesalers because of this. 

Be very cautious on how you approach this in the future.

I believe the best option incorporates all three approaches, in the following sequence:Connect with knowledgeable local investors to quickly get a sense for the many sub-marketsBuild a core team of capable professionals (PM, inspectors, contractors) who are goal-aligned with you and also have no conflicts of interest among themselvesDo a single small deal to establish a work process for the team and get a minor win.Make strategic visits, not to inspect rehab work but rather to strengthen your relationships with your core team.Do more and larger deals, adjusting the team as necessary.This is exactly the approach I'm in Lubbock, Texas today and would love to compare notes with you.

Hey there,Are there any minimum qualification like needing a high school diploma or having a GED for becoming a house flipper or having a buy and hold approach? 

In terms of structuring you can figure out how you want the partnership and then you can market it to investors that will likely go for that approach.

I had about 20 rental doors in 1 1/2 years and this is all while maintaining a full-time job.My approach was basically buy, fix up, raise rents, keep for a couple of years and sell which I did with many of my rental units.

Then you could approach your dad with a concrete plan instead of a pie-in-the-sky dream.

I think you took the right approach of just trying to get into something and start learning.

I'd personally try to incentivize him to clean the property before applying pressure in terms of an eviction - carrot before the stick approach.
