Here's a video with some tips, but I recommend you watch several videos, read some blogs, and educate yourself on what to look for in a brokerage:

Quote from @Fernando Martin-Gullans: Hey y’all, I’m a retail investor with 2 SFH rentals worth a combined ~$650k looking to utilize some of my stored equity to buy more out-of-state properties, but I’m not quite sure how best to proceed given that my interest rates are incredibly low (leaning me away from refinancing) and neither property is owner-occupied (which I believe prevents me from using a HELOC).

Here's a list of things to track:- Formal lease application- Formal signed and executed lease specific to your state- Payment history (I recommend using online rent collection like Apartments.com, RentRedi, etc)- Maintenance requests and receipts- Accounting for all rental-related expenses (repairs, utilities, etc) The more you treat it like a business, the more helpful you are to your CPA come tax time. 

and some guidance from the FTC is here: https://www.ftc.gov/tips-advic...Simple solution - DON'T.

Quote from @Diana Teng: Hi all,I think my question above is pretty direct.I'm interested to buy my first rental property, and after doing a brief search I see that there are quite a number of places out-of-state (I live in NY state)  that offer affordable homes that deem to be in hot market areas right now (according to many different articles online). 

Go to Etsy and search for "rental property tracker," and you will find hundreds of nice spreadsheets to track 10-20 rentals, usually for under $10.Software has extremely helpful features like online payments, marketing syndication (click a button, and your property is advertised on multiple sites), electronic document review/signing, maintenance tracking, and owner reports.

Again, the BiggerPockets store has some books on this topic, or you can learn about it by watching podcasts, reading blogs, and interacting on the forum.

So anyone can put together the courses and sell them just like any other RE Guru out there teach their tips and tricks.

@Tim Ryan thanks for the tip!

Also just look online and steal some ideas...I used to Google Luxury Kitchens and then figure out how to do the same for less $$.You'll be fine with your experience.
