Details meaning credit score, property address, type of property and total number of units, square footage, purchase amount, rehab costs, monthly rents, annual tax, ins, and hoa dues, after repair value.Hope this helps.

It has been hard to find good and reliable contractors to do repairs and emergency service calls.Anyone has good reliable handyman/plumbers/carpenters/contractors that can refer to me.Thanks in advance

This would buy you time to do the repair and while you figure out the tenant issue. 

I would like to buy properties all-cash from motivated sellers with some to no distress on the property, and then rent them out under a property manager after repairs. 

If the unit is damaged because the leak was allowed to continue, I would charge the tenant for the additional repairs required.If tenants have such obvious lease violations, there is a high risk of additional problems down the road.

Once repairs and rehab done the value goes up to market value.

Historically though condos don't bring much equity but do bring high turn over, repairs, evictions and fees....this  means more risk. 

Brandons book on no and low investing does not go into much detail at all about legality and techniques and most videos do not either.Thoughts from experience?

I wrote a BiggerPockets blog post on how to find comps and calculate the ARV of a potential deal: https://www.biggerpockets.com/blogs/8814/68395-how-to-find-real-estate-comps-and-calculate-after-repair-valueHappy to answer any questions about that blog post or the process in general.As far as finding potential deals, those are slim on the MLS and you'll get the largest spread for your buyers by looking off-market.
