Laptop such as a Macbook? An electronic pad such as an iPad? A desktop at home? Or do you keep it old school and use a pen and notebook?

@Kevin Fox Not trying to be argumentative but this is what it looks like on Zillow Foreclosure data which is where I picked up the 5 I'm considering now; two of which I've already put offers in on and one which is a pocket listing that another agent is actually renting.I know what the stats say and have no reason to doubt them.

We fixed it up and than rented it out when we were transferred.

I used to buy paper from local Portland thrifts in the day.. but the manager that I worked with got transferred and the new manager would not engage... time to dust that one off.  

For example I have found more than one site with multiple notes that predate the most recent transfer of the property--the borrower and the property owner do not match and in some cases the borrower has not owned the property for a couple of years. 

Been at this for 18 yrs and have always taken the position:Can't trust the applicant to do this correctly and you may well get last years which is useless.I pay for the reports (cost of business) and get current data from Experian or Trans Union.I pull the CR, BG, Eviction reports ONLY after they pass muster:  Verified employment, income, prior landlord comments, so the expenses are well constrained.I also ignore the FICO score as that's the Banks view and I'm more interested in the 30,60,90 lates as that demonstrates their current habits.

I own 3 properties and I am onto the fourth house.If I buy a property in my name and have a mortgage in my name, how can I transfer to LLC?

You can get this data from the MLS or even buy it from list brokers like listsource. 

Our number one source for sold data is the MLS; followed by pulls from public records.
