Or would you say your best bet is to manage the complex (if even) properties yourself?

Your best bet would be to link up with some wholesalers who have been doing things on their own or with a small team. 

I bet you are quite the salesman for some people.

I'm in Ludlow, VT and found there's a zoom call tonight to go over a bunch of items, to include an update on the rental registry pending regulation. https://vtstra.org/regs My property has an accessory dwelling unit with an established long term tenant which looks like will keep me safe from future push on my STR.

What if (fill in the blank) To me the point is not how many doors doi own, its more how do I best ensure I have a stable income (that hopefully increases over time) while keeping my nest egg safe  

That's mostly safe. 

Then I'd search for units that have been leased a while, call the owner/LL, and explain why it's 'safe' to lease to me.But please, as an owner of multifamily, stop asking "do you accept corporate leases" as a round-about code for "Can I do STR in your property?"

The slab was deemed safe by the appraiser and passed the inspection.

I think it’s safe to say though that with the way the foundation repairs have gone, it really won’t have much of an effect on the home shifting and we can now begin to tackle the upstairs units.   

I think your best bet is syndication/limited partners.
