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.

The only way to answer that in general (whether house hacking in today's market is still a good option) or for a particular property, is to learn how to run the numbers and analyze a specific property to see whether it will be able to stand on its own as an investment when you move out someday.There are a lot of resources here on BP for doing that but I'd just say, make sure the assumptions you're putting into your spreadsheet or deal analyzer are realistic.Make sure the rents (especially for vacant units or pro-forma #s) are realistic by doing your own rent comps; make sure the mortgage rate is realistic by doing some research online and/or talking to some mortgage folks; make sure insurance #s are realistic by getting a couple of quotes for the # of units and zip code / area you're looking in; etc.I hope that helps, and good luck 😊

When I did an online search for commercial multifamily lenders, most have a minimum lending requirement of $1M and I don't need that much. 

In my experience, most of the online calculators are just taking an educated guess for you.

I wouldn't say you're going to learn as much going through an online course as you would an in-person one, but it is a lot more convenient. 

check the local municipal code, most are online.

Take a close look at what other similar units look like on Zillow or other online listing sites and try and mimic them or exceed them.
