Reality:  not so much.For lead generation BP has been my only source that has worked, but most of those leads only ever want to look at MFH, and I've learned the hard way MFH data is sucky beyond repair in the MLS.No closings. 

I suggest coming up with some foundational goals you would like to achieve- certain amount of cash flow, what markets, # of units, year built, asset class, etc- and then start looking.

I am a new investor and a newly licensed RE agent in Iowa, so looking to learn from seasoned investors and am aggressive in what I want to achieve in the near future. 

With condo investing, you don't really need an amazing investor-friendly agent to do the data, you just want someone who can run rental comps in the same complex so you know what your expected rents will be against the HOA and taxes and payments.

As a credit bureau, TransUnion offers some of the most comprehensive data to managers at a competitive price.

IF you can find a seller financing in MF, they want 35-60% down with a 5 year ballon, but this varies greatly from market to market, as well what the seller is trying to achieve with cash flow and taxes

With these three data points, you can arrive at the expected value of the property. 

The other thing I recommend is picking a niche within a niche and becoming a master at it. 5 transactions in your first 12 months is a very achievable goal.

This is usually a 2-step process. 1. pull a list of people likely to want to sell their home. 2. append phones and email to that list where available.You can work with a list broker to walk you through and make recommendations for your target.Please note that "loan balance" is not public data and the only sources that do have it are credit score companies and there are a lot of legal restriction around selling the data.

City data and census data are a great place to start for general market data.
