Hey guys, we are closing on our first real estate deal this week. It is a 4-plex and we will be living in one of the units and renting out the other 3.  We inherited 3 tenants. All 3 tenants signed year long leases about a month before we put in the offer on the property.  We intend to self manage and are unsure about what we can do when it comes to new rules, or payment systems (we want to use avail), etc.  Can we make a new lease agreement and have them sign it?  I am assuming the rents cannot be raised until their previous lease expires, but can we change other things?  We are fast approaching closing and I don't know the best way to make this transition.  They all have newly signed lease agreements with the previous owner...and now we own the property. What is the hand off process like?  Any advice on this issue would be greatly appreciated! Thank you.
