looking for my first multi-family deal, is it worth it?

[Jeremy Jackson]

I still working on landing my first multi-family property.  I have my eye on a particular property.  My past experience has been live-in flips so I need some help here.  Is this a deal?

Property is a 5 unit building and generates $480 per unit, $2400 monthly, $28800 annually.

Annual taxes:  $2400

Annual insurance:  $981

Owner pays water/sewer/trash (I don't have those figures yet)

Roof is new.  Property is older but very well maintained

All units are occupied and vacancy rate is low.

Asking price is $155k.  

Additionally, how do lenders determine what they will lend on rental properties?  Thanks in advance.
