As I'm still new to the game and haven't found my first investment property just yet, I would say start exploring with/toggling the different calculators BP has to offer, they provided some insight into the overall costs and how cashflow can be considered.In regards to condos with HOA's, I actually started searching for different articles about condo investing and found this which cleared some things up for me, maybe you will find it useful: https://www.biggerpockets.com/blog/2016-05-27-ultimate-guide-investing-condos-townhomesFinally, I'm still bouncing back and forth between the idea of a SFH and MF properties.

Having someone to bounce ideas off of (especially renting out a terrible property in a high crime area) is so important for us new investors.

BP is a great resource for finding like-minded people to bounce around ideas with and learning about creative ways to structure deals. 

You capture all the bounced addresses and can skip-trace those, those are valuable.

You will also find the skip traced email addresses are pretty bad so it would also likely get a lot of bounces and spam traps so could hurt the reputation of whatever IP you send from so not worth it.

If you send them a refund, the check they sent will bounce.

Right now I have 2 books I'm bouncing between plus the rich dad poor dad audio book so I'm a little overwhelmed with information.

He already bounced a check.  

I have been searching for investors in this area to bounce ideas with.Personally, I think you did good.

You're getting a mentor, a person you can bounce you're ideas off of and he will certainly keep you legal as his license is at risk.
