You can go to the Airbnb website and 'host' properties and areas that will help you a lot with pricing and assumptions.

@Neil SeldomridgeThe website is becoming that as well.

Once, I buy them, I plan to aggressively prepay them and increase my cash flow.I am looking for a tool, app or website that can help me create a financial plan to continue saving, investing and financing properties.

I setup my account previous week and just getting ready to run tenant screening,  when I try to login got error message.    is anyone else see this ... or this is just weekend maintenance?

If so then go to your county website and look up the property tax records.

Then visit the lender website and see if the have an REO section or try to find a person's name.

This can be found on the county auditors website in many cases and will help you verify if the changes you see are in line with broader urban planning strategies.Engage with the Community: Sometimes, the best insights come from local residents.

Professional investors do this by sending thousands of mailers to distressed property owners, or building local "We Buy Houses for Cash" websites that rank well locally in search results. 

What you need to do is hopefully go to the lender's website (that your relative was using to pay the mortgage) and just make payments to the bank. 

Any websites or apps you recommend on getting the most accurate data?
