If I can link with other people or join discussion or seminars from locals or even online that would amazing!!

From reading online, auctions on average only recover up to 37 percent of the owed mortgage.   

especially at the moment when you have a lot of vacancy (may increase further when you enforcing the rules short term). keep in mind vacant unit don't generate income and it's still a great return on investment (full year of rent vs what incentive you offer). that may keep him more motivated. also, I'd personally help with generating leads for new tenant and have manager mainly helping with onsite tasks (showing, move in, etc) for the short term. considering he's 70 years old as you mentioned, he probably are not as effective as using online tools for generating lead (FB marketplace, zillow rental manager, etc)Originally posted by @Cody Furman:Thank you, Bjorn. 

You can also check their reviews online at Google, Facebook, or Yelp.

Now to my question, is their any site/blog/video that explains majority of the terms or do I just have to write them down when I come across them and research them?

What I'm trying to say is to be very careful owning only 4 units a gentleman that has been buying apartments for about 25 years and owning about 5,000 units and is a multimillionaire has taught me a few things with his many videos on YouTube and being on with Josh and Brandon a couple times and doing many public speeches and predicting he will make about 150 million this year might qualify him as knowing what he's doing. 

I been looking online at properties there and the prices seem to be around my price range.

Hey Juan, if you like online classes, Real Estate U works good. 

Don’t inundate yourself with videos and workshops and meetings.

I have started my own research as well looking here on bigger pockets reading some estimating rehab articles and watching some videos.
