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. 

Bonus points if they can refer you to reputable contractors in the area. 

Alternatively, there are high-yield online savings accounts like Marcus or others - the difference is that banks have some inherent risk, thus the FDIC insurance. 

Has anyone worked with this company, or done any investing in this asset class that can provide any feedback or recommendations including reputable companies with good track records?

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

You do that with skill, time, and reputation.

Are there any good resources online to be able to get an idea of average monthly/yearly expenses like utilities, etc. for a given zip or city?

The forelcosure auctions in my home State of Florida are all online.

There's nothing wrong with seeking concessions if there are issues that arise in the report, but using this as a strategy will garner you a reputation within the community if you are repeatedly going under contract and then seeking large re-trades.
