#BRs Baths and narrow location will be able to help there... jump on zillow, or trulia and see what other LLs are asking for in the area where you are looking...

For instance I have a tape of over 500 right now that I'm narrowing down to fit within my company's parameters. 

IRR sensitivity tables around rents and exit cap rates show that many B and C class properties can absorb a fairly substantial compression of rents and cap rates and still remain profitable.Under that stressed scenario, what's interesting is that the passive investors on deals with preferred returns appear to do fine but the sponsors will not be making much money. 

We have it narrowed down to two names.

When determining utility averages, how narrow of an area/areas should I be looking to find an average for?

looks like you no longer have this issue.But in the future if it happens again what's been mentioned so far - screen the new tenant, fill out application form, collect app fee, and have all existing tenant sign.IN ADDITION, make sure the existing tenants and new tenant understand, and include into the addendum if necessary, that all claims, damages and deposits are shared by all tenants from this day forward.That means if you see a broken window and need to charge them for repairs tenant C can't say oh it's broken before I moved in.Or if tenant B moves out and six months later you charge a deduction in the security deposit on a hole in the wall behind the couch he says the hole wasn't there when he moved out so it's not coming out of his deposit.At the end of the lease when you refund the deposit it will be a check to "A B and C" jointly regardless of who might be there or not at the end of the lease.

Setup time to speak to a few of them to learn more about their model and get a feel for how they answer your questions, how they treat you during the call.Be prepared to share your net worth, income, and investment history with them if you want move forward.For the ones you like (after speaking with them), maybe have them send you example investor communications on prior deals so you can see how they communicate to keep investors informed.Once you've narrowed it down you'll want to further evaluate the sponsor Track record, references, etc.Have them present a past deal in detail to try to understand their assumptions, are they conservative, etc.You can use the BP Tenant Screening tool to get criminal and credit history.
