My best advice for getting started is to learn to run your numbers thoroughly and then practice on potential properties that you see listed. 

Nope, most of those multi-family listings are in the hands of big-shot brokers who pretty much control the market.Finding those deals means picking the right place to dive into.

Make a list and look closely at each one to see if they are an option.If you can't find someone within your network, expand your network.

I can send you a list if you reach out to me.

I tried to find a simple way to do it by searching for a website or app that has all the options listed and matches them to me (think Tinder for investors and PMs lol) but didn’t find one.Do you all know of an app or website like this (for the USA)?

I also wrote a program to automatically populate the spreadsheet with MLS listings from my agent. 

Mid term rentals tend to be listed on many different sites so I would also recommend looking at Airbnb/VRBO for 30+ day stays and Zillow as well if you haven't.

The larger multifamily properties can create great cash-flow but you can also make costly mistakes.As for the difference in loans, I can send you a list of lenders in Ohio.

Looking for other options for listing apartments for rent. 

There aren't alot of recently sold properties under real estate listing tab for memphis in BP, what other tools are you using to gage the ARV?
