It were mine I would have those cracks caulked up, As well as the seam between the cement and the foundation, hoping that the slope is good enough to remove the water from it when it rains in the direction it was intended to move when it was poured.Good Luck!

Saw and bigger hammer if it's fieldstone or poured cement.  

I've heard the horror stories from landlords about how the tenant they were evicting poured cement down the toilet, played hammer darts in every room, ripped out the copper, or left piles of garbage for the landlord to clean up.This hasn't happened to me - my last tenant just left untidiness that took me about an hour to clean up.

Tree guy, cement guy, foundation guy (yes, around here, they're all men!)

I know a lot of the homes in PR are made of cement. 

This particular cat urinated all over the drywall on a wall and the cement in the basement.

To your point about a partner, I would be willing to, but I haven't cemented those connections yet to feel confident.

@Stephen Rodrigues- thanks   1)  I would recommend  asking for some  referals for  agents  from  people that you know in the area ( if applic)    2)  if you need to use  financing - get  a free pre approval in  place  for any scenario you want to use  and ask the  mortgage person for a  realtor  referral or two  to connect with   3)  visit the area for an  extended  amount of time to get  some  connections  cemented and also  to look at some  options  so you can  determine if this is  worth proceeding with 

Not sure if city / county code laws do not allow for the homes to be modernized with materials such as fiber cement board / hardi board panels.  

Just stick with a fiber cement product over a vinyl product, or go with the cheaper priced product backed by a lifetime warranty.
