I will rent them out
In residentials its not that easy,those SUITCASE tenants tend to leave where as in commercials once the tenant starts making money he will be there for years/decades,without giving you any hassle.And you can squeeze them a bit also depending how much they are making.Also if you sign right 777 umowa you can get the commercial tenants out in 7 days on conditions agreed upon,in case of residentials forget it.
@ Kaprys:I prefer otodom which has more descriptive situation of the property then OLX
