Rent Collectionand expense tracking after Purchase

[Chadrick Bailey]

Hey BP fam, I'm purchasing a three unit property that'll I'll be house hacking in Pennsylvania. I close on the property next week and I'm inheriting two tenants that are currently on month to month leasing but will switch to long term after purchase. My question what website should I use for rent collection, lease signing and expenses tracking and should I have separate bank accounts for each unit for tax purposes?
