The positive camp of my local investors are telling me it is going to transform the area because more people more business moving in will raise the house prices and rents, while the negative camp is saying that the complex will draw all the quality renters in my area so the house prices and rents will actually go down.If you have come across something similar before, please can you comment what was the impact?

some youtube channels recommend finding buyers first , asking their criteria but some say to find the deal first market it & then buyers will come to you ?

There are multiple YouTube videos that show a red rag in a load of white rags in a HE machine.

I watched the BiggerPockets YouTube video on the 4 square method and I’ve been trying it on some properties for sale on the MLS in my area.

Start studying as much information as you can about real estate investing on sites like BP, YouTube videos, etc. 

Youtube check out Max Maxwell 

My advice (from a person that hadn't done a lot of the work himself previously): YouTube.

From watching youtube videos, joining Facebook groups, and following BP forums, there's tons of information available out there. 

There’s a lot of information that people give out free information on YouTube and some might not click with you.
