Or for litigation?

Some differences between SFH and MFH (4+ units):-you will need a licensed architect-you will need a licensed M/E/P engineer-you will need a civil engineer for the usual grading/drainage, plus consolidating the 2 lots and/or the condo split for the townhomes-there may be other consultants required for landscape architecture, environmental studies, etc.

When I did screenings,  I did the usual credit/civil/criminal background check,  verified income,  interviewed prior landlord (almost nobody seems to actually do that - at least none of my former tenants have ever resulted in a new prospective landlord calling me)  and for anything less than perfect I asked some combination of  2nd months rent,  co-signer,  or increased security deposit.   

You can find it through my profile.I'm not sure why Nigeria is in your list: corruption, civil unrest, poverty, little tourism if any.

We had more fake pay stubs and discrepancies on applications vs. civil court records than ever this winter.  

The tenant will be facing criminal charges and the landlord civil.

They indicate which ones are litigators but not on DNC.

I can't remember the investor here on BP that recently had a thread going about his litigation experience regarding a lead-SAFE property, but it was a very eye-opening thread.  

Can they absorb a litigation and another capital intensive project on top of scheduled R&M?

You'll find you can make the best deals on properties that are distressed - i.e. recent or pending landlord/tenant litigation, on tax sale list, yard unkept/snow not shoveled 24 hours after snowstorm ends, hoarder house, etc.
