I was inputting some sample property data into the rental calculator, and as a newb, need some insight on how some metrics are calculated. 

She has aggregated data on trillions of dollars of mortgage debt, and prices according to the risk that data says exists. 2.125% of loan amount less @ 75% LTV, 3.375% @ 80% LTV, a tad over 4% @ 85% LTV.

It's a bit of investigative work, because most likely you will find that most or all of these properties of this size will be held by an LLC or a corporation -- from there, you can proceed on trying to find names behind those companies by searching in the Secretary of State filings in the state of which that company was formed.Once you have your list, start calling or mailing.If you don't want to spend the time doing this on your own, there are subscription based services out there that aggregate this data for you, but of course for a price.

Your reasons could be shored up a bit with data.  

It turns out they're no longer receiving Foreclosure/NOD info from the county (at least where I live), so all they have is generic homeowner leads--not a good investment.I'm looking for a suitable replacement, that a) doesn't cost too much more (ie. under 50 cents per lead)b) specifically offers NOD and/or pre-NOD (preferably both) with custom zip codes and other criteriaThe ones I've come across that fit this are:- Consumer Data Leads (CDL)- www.yellowlettercomplete.com *- www.yellowletterhq.com ** Note: I plan to create my own yellow letters (as it's cheaper than having them pre-made), but these websites also have options to buy leads.I'm curious, but also skeptical...none of these businesses will say exactly how these lists are obtained (from a broker, directly from the county, etc.).Anyone have experience with the ones cited above, or any others?

Be data driven.

Me and my Team created a share point with numerous data and we have designated responsibility on what to provide to make the best/correct decision.

Then attending local REIA meetings, but being careful to really just gather data and not get caught in the negativity or personal opinions of other investors. :)

I am finding it frustrating to find and collect all of this data, not to mention I don't really know what I am looking for yet.  

Does anyone sell data of Tax delinquent, code violations, or eviction violations?
