@Sohail Ahmed Jokhio from your questions, it appears you are looking at real estate investing as a "job" or a university curriculum.There's NOTHING stopping you from accessing everything you need online - except the limits of your perceptions.Not aware of anyone here that's going to be your guidance conselor and lay out what you're asking for.

I have a portfolio of four units (comprising two duplexes) near the University of Illinois campus, which have been profitable over the past seven years.

Purchase price: $182,250 Cash invested: $73,000- Residential area that is close to University of Rochester- Spent $20K in renovation of the aged unit and increased the rent from $750 to $1,450. 

(I won’t go into actual numbers because who knows what horrid people lurk in the online universe.)

The population has been growing here year over year over the last decade, it is home to The Ohio State University which has over 50,000 students that live here along with those that visit, and it also holds a diverse range of young professionals and traveling nurses to fill the demand of the multiple business corporations and hospitals stationed here.

Places like Maple Heights, some parts of Garfield Heights, Warrensville Heights, Shaker Heights, University Heights, and Cleveland Heights.

When the market universally raises rates end buyer affordability becomes a non-factor to such price increases, in terms of holding such back. 

My focus has been on University towns with football.

Hello, I am a student-athlete at Ball State University and new to the real estate investing world.

Quick thoughts on the markets you're considering:Knoxville, TN: Growing, affordable, and a strong university presence.Huntsville/Montgomery/Tuscaloosa, AL: Huntsville's got tech, while Montgomery and Tuscaloosa have colleges.Asheville, NC: Popular tourist spot, but competitive and pricey.Akron, OH: Affordable, but keep an eye on the local economy.Irving, TX: Part of DFW, so a big market, but prices are higher.St.
