(ah, so paid answering service given the script "this is zillow" I use one as well for my business accept that the service pretends they are in my office referring the call to me instead of pretending to work for a totally different company in a bid to trick the caller). 

DOES ANYONE KNOW OF ANY affordable/free CRM’s that are iPhone compatible and will pop the callers info when they call?

You don't want to quit your job only to discover (as most newbies do) that what you think are deals, aren't good enough to sell.2 hours a day 7 days a week is 3,000 leads a month if you're an efficient caller.

I had the credit report run through cozy and it gives me the following info:Contract Callers Inc  ACCOUNT SERIOUSLY PAST DUE DATE / ACCOUNT ASSIGNED TO ATTORNEY, COLLECTION AGENCY, OR CREDIT GRANTOR'S INTERNAL COLLECTION DEPARTMENTBut it does not give me any info on the cause and what the original debt is for.

I do have some missed calls where callers do not leave a message. 

For example, the skiptracing VA does get good phone numbers for a really cheap bulk amount FIRST (@Ryan Blake) and once I literally can not get in touch with the homeowner after having my caller VA's calling each number (30-40% of the leads unreachable) I would use a skiptracing service a pay about $1.35 for each lead ($40 monthly no-contract subscription).

Long time listener, first time caller =0D      So, I'm making moves to purchase a 17 unit, 11 apartments, and 6 retail on the ground floor. 

When I get a call from a letter, I tell the caller I'm an investor.

And it's possible that after all the bids on all the combos are in, and it looks like everything will be divided up and sold a certain way, but it's not yet SOLD... that the bid caller goes back for a last chance at the entirety and somebody who has been standing quietly in the back comes in and wipes out everyone and takes it all.Doh!

Hire a cold caller to call other tenants in the area to pitch your building.
