Websites like Zillow often have owner information, especially if the property is currently listed for sale or rent.

@Jay Hinrichs has a website you should check out that is evaluating turnkey companies.

Don't forget that once your LLC is registered you will also need to go to the IRS website and request an EIN.

Is there a good website for where you can input the terms to track the loan? 

You need software to do due diligence (websites/skiptrace etc).

Start on a small scale, handle your student debt and daily costs, and think about smart funding ways like getting the seller to help, borrowing from private lenders, or using websites that gather money from lots of people.

I see some states have free e-file via their websites: for example just checked for CO and they have it. 

So I pull over, get the address, get the owner's info from the county assessor's website, & add the info to a spreadsheet.

Study various websites like Zillow, realtor.com, apartments.com, Facebook, etc.

The septic information on the existing property is public record. look up the property on NHDES website.
