1st future rental and inherited tenant help

[Alfonso Mora]

Greetings everyone! we are getting ready to buy our 1st property (duplex), we are going to check a duplex in a few days,this one has both sides occupied, they're on a month to month lease, now my first question is while checking the place what are the most important things we should look for? roof and ac are a must for sure, second question is since we are gonna live there that means one family will have to leave and we have to decide which side we want so how do we approach this in the most delicate manner? and third question is whats the most important to ask the seller about inheriting a tenant? any help would be kindly appreciated, thank you!
