I’m an agent from Los Angeles that has sold going on 5 multi-units to LA investors for the purpose of both TV Production housing and AirBnb.Their cash flows are very healthy thus far, although this will depend on how you finance the acquisition.

This would require two closings, and you would have to come up with money for both.Although FHA is very useful for people starting out, 100k is a lot of liquid capital you can utilize on an investment property. 

What the IRS does stipulate that all activities of the plan must be for the exclusive benefit of the plan beneficiaries.The IRS recommends the following criteria to determine if a plan’s policies are for the exclusive benefit of the plan participants: The cost of an investment must not exceed its fair market value (FMV) at the time of its purchase.A fair return commensurate with the prevailing rate must be provided.The investment must be sufficiently liquid to permit distributions per the plan terms.The safeguards and diversity that a prudent investor would adhere to must be present.So put that in perspective relative to the lending arrangement you are considering.

He inspected the unit and performed a liquid treatment 3 times - he would treat it, then come back a few weeks later to treat again, and then again.

@Nick Brubaker, this all depends on what loan product you are looking to get into. 

A lot of forum members are very knowledgeable in their respective fields related to real estate investing, whether that is real estate sales, wholesaling, flipping, rentals, lending, self-directed IRA and Solo 401k investing, or tax and legal guidance.Discounts on some products and services are offered to BP members: https://www.biggerpockets.com/perks/proIf you haven’t been to it already, you might want to check out the BP blog: https://www.biggerpockets.com/renewsblog/The site has quite a few tools that can be helpful for new members.

With the information you have gave me, I'd say the 5% down with PMI is the best option, as you get to avoid the higher interest on the 401k loan and the marginally higher interest on the cash-out refi, and you get preserve more of your liquid assets.

I also diversify and have 5 short term rentals in E TN that do really really well.

Plan, Plan and Plan some more.By the time you are ready you should have alot of liquid capital (down payment and reserves), and 800 or higher credit score and a solid plan of attack.Will this take time?
