We also state in our lease that the tenant has an obligation to pay 12 months of rent and we will collect it one month at a time. 

I do 2-4 rehabs per year through my company and I try to collect as many rentals as I can.

Nice to get the judgment - - but seldom do we EVER collect. 

Check to see if the rents they are currently collecting are above/below market average and could these be raised.Some places to compare rents for that area are rentometer.com, zillow.com, craigslist.org.How much it'll cost to bring each unit up to rental-able condition.

NOI is Gross rents - vacancy and collections and operating costs. 

It's best to assume your investors will eventually need to levy someone's bank account, so having this information before a lease up will expedite the collections process.Also, this may sound like common sense, but be sure to get a signature authorizing the credit pull and investigation.

some keep it for collection efforts, some forward to the LL. 

There are loan servicers out there as well that can handle the payment collections and tax forms for both the seller and buyer as well so you can put this on auto pilot.

Hi @Ben Smith I agree with @Jeffrey H. on the financial end.A question you can ask that will give you some insight is "How much revenue do you collect in late fees over the course of the year?"  

The main issues I've found in low class properties is:High turnaround=Vacancy and Make-Ready costs.Rent Collection=Very hard to collect rent...It's almost like having the property vacant.
