If it is a good investment and there is an significant upside worth purchasing, removing the past due tenants and making simple improvements to raise rents would be another one of my objectives.

The objective is not to do this over and over again in my SD IRA, but really to do it just once or twice, and prove that I can do it. 

Today machines can be equipped with coin as well as digital payments like Apple Pay or Samsung Pay - it works off a Bluetooth connection and is a modestly priced upgrade to a laundry room.   

My objective is to buy and hold (multi-units), create passive income and eventually invest full-time.

What is the objection?

True, your cash-flow will be lessor, but if done right (and a little good fortune), you could easily end up with double digit properties and an extra $100K or so in hand by the end of the 2 years.

I currently work and have worked for the past 5 years for a digital marketing and website company, so if anyone has any questions about digital marketing or websites I am happy to help where I can! 

Perhaps the biggest pitfall I would say to avoid is the "Shiny Object Syndrome".There's so much to cover and I'm sure others will jump in and cover what I may have missed...

(I am now going to tread lightly and objectively on a touchy subject and will avoid using names)One of the things I see here in Utah is big meetup groups and high-cost (up to $20k) real estate "communities." 

You could try installing blackout/noise reduction drapes.Have you dug deeper on the objections about the noise?
