What I would do different: aside from starting younger, I would have bought a wreck, lived in it while I rehabbed it, moved into my van and sold the rehab, did it again until I had enough cash basis to ramp up my rental property buy & hold purchases.

OTOH the tenant in your half probably won't make you evict him, nor will he wreck the place.  

My opinion is that if either porch structure collapsed, it would wreck the house and hurt the foundation even more.The second biggest issue we have is half the walls and ceilings show sign of sagging because the plaster has come undone, this seems to be a pretty expensive fix, considering it's in both kitchens, and most bedrooms in both units.

When I did a drive by, I identified this total WRECK of an apartment complex was parked right behind 3 beautiful bay front homes worth around $1M each.

It is a train wreck.  

I don't know what to do; I am a total wreck.

So as you can imagine, it's a wreck.

Curt we tried the paid off home owners and it was a train wreck!

This is very exciting, but nerve-wrecking at the same time.

But, I do my own property management.No issue booting one tenant, but since they have already wrecked it, maybe readjust expectations and see how many months you can get from them to defer the rehab costs.
