Harrisburg, PA area security deposit and 1st and last month rents

[John Fider]

This is a townhome in Middletown that I'll be renting out. Is asking for security deposit, plus 1st and last month rent up front asking too much? How do you set up your upfront cost requirements from your tenants? 

And once you receive the money, where do you put it? A separate savings account where you put all your tenants security deposit and 1st and last month rents? 

Thank you!
