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.

Their new online system is really confusing, and I have had to call customer support for help each time I needed to wire/ACH funds because I could never figure it out on my own (and their customer service chat box isn't set up yet). 

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 😊

check the local municipal code, most are online.

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

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. 

Search for this in a Michigan Public Notice legal newspaper or an online legal notice aggregator site like USALEGALNOTICES and the fount of MI pre FC/FC data will be available to you.

You can create your own, or there are house flipping spreadsheet templates available online 

I just can't find ANYTHING online that isn't from Chris or his team. 

I've seen some conflicting information online, so getting it right from someone who does it would be amazing!
