isuf - congratulation on taking the plunge and I hope you success in your first property! What type of help are you asking for, with more direction perhaps we can give targeted advice/assistance.
In absence of specifics I would recommend ensuring that you know the following
1) current going rent for similar size 3br/2br within about 2 blocks of your new property
2) specific information and/or service you will use to screen potential tenants
3) understand your expenses and identify candidates for reduction [e.g. water saving shower head, water saving aerators, weather stripping leaky windows, etc)
4) source of potential tenants to target, method to gain their attention [fliers, online, rental service, etc.]
5) Needed repairs and/or improvements to get the building to 'operations' level - meaning so that you will be in standard maintenance mode instead of constant repair.
Just a few items that immediately come to mind.
Good luck and let us hear about the experience.
