@Manasa Srinath Agree with the comments on timing and # of rentals coming online. 

I've read all the books, listened to most of the BP podcasts, and have spent considerable time doing research online.2 years ago I purchased my primary residence where I live in California and now I'm trying to purchase my first rental.

This is probably the best way to get online exposure. 

Simple things like a professional website, ability to take payments online, a real tenant application/screening process, maintenance tracking, after hours call system, financial reporting, etc. 

I got these numbers from realtor.com because the county assessor does not list these figures online. 

Online contracts? 

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

Like I said, this is not for a quick online answer.

I'll sharp my question, is there any platform or certain ways I can manage all the basic aspects of investing like, finance, properties analyzing without seeing it in real life, property management , properties buying ans selling, accountants handling and lawyers, taxes etc..BTW I'm visiting the US in a couple of days, anything I should do while i'm there ?

If you’re going to self manage, start with self-listing on those platforms.
