You will also need a french drain outside of the home to drain water away from home.

Once foundation is exposed,  we will:add a concrete sealing solution to enclose all open poresCover foundation with membrane as an extra moisture barrier install a French drain. 

-------------------------------------------------------------------------------------------------------Tim sounds like you have the French drains.

I have 20 units and all have 2 part deadbolt at front door.On the backs some have french doors and others are sliders with no key locks.I am not looking at holding long term so will put limited money in just to make livable and cash flow.From what Marc describes it is an involved process and my time is limited as it is and I can see it now my PM calling me and tenants having issues with the pins not working etc.If the cost wasn't real bad I might look at it.

If I remember they were on French Street.

For the drainage, we bought new gutters and attached the downspouts into a french drain with an emitter at the end.

In the province Where is reside we speak English and French.

BUT a french bank may well make the loan, even to you as a foreigner. 

Kudos on inclusion of the Irish, French and Greek accents

In Belgium you need different types of permits.I am from the french speaking part, the rules are "local" so check, but in Wallonia you needRental permit for anything below 28 square meter of effective living area ( bathroom and corridor excluded)Urbanistic divison permit (prove that the building is officially divided in appartments).Do you have utility meter per unit?
