This is one of the better tools to learn about REI.

They have this really good profit analyzer tool I like too.

I'd recommend going directly to navyfederal.org or penfed.org.Hope that helps, let me know if you have further questions on these tools to access equity.

The boundaries of a neighborhood can be larger streets, tracks, parks, etc.A house as close as possible in features (beds, baths), size, etc.Using the same financing method, with an arms-length transaction.Once you've found the right comps, then you have to make adjustments to them based on all of those features to get an accurate value for your property.I used to use a spreadsheet for that, until I built this tool: www.reikit.com/compsThe tool uses Zillow data for lookups, but usually I go in with my own set of comps from my realtors then use the tool for adjustments.The hard part is getting the comps, though, and MLS is always going to be king.Cheers!

I'm still optimistic that technology will heal the industry by giving quality sponsors the tools they need to bypass intermediaries providing little or no value.
