In Search of Good Research Tools

[Maria Stewart]

What types of tools are you using to research properties? Are there any websites that make researching easier or more comprehensive? For example, when looking up tax sales, is there an easy way to find information about all or is it a manual search (one by one)? Do you know of a website(s) that have a lot of good advice, formulas to evaluate buy-hold or buy-flip properties? Any help is appreciated.
