Long distance rehab: hire project manager, or pass?

[Lance Luvaul]

HI BPers, I live on the other side of the globe from my "farm", the town where my 3 current rentals are (I use a trustworthy property manager), which were all move-in-ready when purchased.  Now however I've just identified a potentially great rehab (a run down 2 bedroom I can add a 3rd bedroom to) in the same town but, since I live overseas, my question is: are remote rehabs considered too hard / difficult / risky to undertake, even for seasoned pros (which I am not); or can the risks be reasonably mitigated by hiring a good / trustworthy project manager?  I would interested to hear of others' experiences using rehab managers (if that's even a thing).  Thanks, Lance
