Most of the programs have expensive add- ons and  generic mentoring through some online " meet-up".

Review their online financials/annual statements.

Poke around online to see if any of those organizations are in the area.Thanksgiving through the end of January is the absolute slowest time of year for leasing properties.

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.

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 😊

I'd rather have a property remain vacant to I can spend time cleaning up and getting it ready and back-online so it could be available for someone else to rent.

I just looked online and saw that in Seattle for months to month lease the landlord is only required to give 20 day notice.

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. 

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 use of online classes has been increasing every year and are projected to continue to increase.
