@Mingze Wang PITI and PMI are the main costs you'll encounter. 

You are going to encounter alot of unpleasant things happen in a market like New Orleans.Its a good question but you’ve got a long way to go.

I picked up the package of 10 rentals.

Personally for me the closest I get to using Big data is looking at the different ways companies are packaging the information on mortgage origination reports, I like to see how investors are buying on the debt side to make the numbers work.

I recently got a package deal under contract from another investor.

Plus I was willing to smack the visitors, if I was in the mood to encounter the ugly things (some nights I wasn't up to do battle.) 

We are waiting on the signage package which includes numbering for the unit doors.

Also can get great package deals around Black Friday and it’s worth it...good luck.

Found a property, made offer and my first obstacle I encountered was when I checked online my credit score was 752, I thought good to go.

But they will never out perform a well built authority driven network that you create not only online but offline as well.Hopefully that helps or at least gets the juices flowin to help you start thinking outside the pre-packaged training :)
