First multi-family purchase - first time landlord

[Tyler Heap]

Hello everyone - I’m closing on my first 3-family property in May and I’m seeking some advice. 2 of the 3 units will be occupied upon closing. Both units are occupied by tenants-at-will. They are both paying well below market average rent. Should I serve a 30-day notice to both tenants the day I close on the property? According to the selling agent, one tenant is looking to buy a house and will be out “sooner rather than later”. The other tenant has lived in the building for 20+ years but as I mentioned earlier is paying nearly half of what the market average is in this area. Any advice/thoughts would be greatly appreciated! Thank you.
