I will be happy with at least $100 cashflow and avoid the mistake of moving and committing to an area that will be far from my job and actually increase my living expenses instead of reducing them. 

Commercial is a heavy lift in the application stage but once the deal is underwritten, you're done, no last minute surprises because you bought a new living room set on a new credit card or made a college tuition payment :)  Also, terms can be negotiated and very favorable (extend the years or reduce the down payment for a slightly higher rate and if the numbers still work...hooray!).

Also, again I want to make sure I can actually afford the multi-unit I get and not be stressed about paying the mortgage. 

Alternative :: do a DSCR loan in your name on purchase based on sale price and rents appraiser says, reduce HELOC request amount to what parents can get approved alone.

With the amount they are willing to lend to us, we can purchase two properties so that my family does not need to go through the stress of house hacking.

I can also sympathize as an agent since multiple offer situations can be very stressful.

Plus, you can realize some immediate upsize by greatly reducing expenses (shouldn't be much more than 40% for a park like this).Hope this helps a bit!

Lets face it, buying a home is stressful. 

If you were putting this on the market today and this guy applied, would you reduce the rent $300 a month and accept him?

It's an easy way to reduce expenses.
