Also I'd say the first step before you get too far is sit down with a great loan officer and let them run your credit and look at your tax returns and assets and come up with the best gameplan for your situation. 

Revenue before expenses and taxes?  

Most seasoned professionals in distressed real estate either transition from extensive careers at real estate firms or legal offices that deal with foreclosures and similar issues.

Typically those don't have much chance of achieving their revenue growth or profit targets.  

Contact your county tax assessor's office to learn how to find this information (it's usually online and easy).Talk to the neighbors.There are paid apps that may include contact information for specific properties.

Purchase price, make ready cost and expected annual gross revenue?

I've had many many people come to our office with a set of plans they bought off the internet.

You will want to run projections on each individual property to ensure that it will produce enough revenue during peak season to cover your low season months.

I like to think our company goes the extra mile to maximize bookings and revenue for our clients.

Then, one could target that subset and reach out to owners knowing that there is "upside" in revenue.
