Here're some online calculators: from Intuit/TurboTax, from H&R Block, from NerdWallet, from TaxAct, and you can find dozens more online.

@Michael Dumler Thank you for your insights man, I got a few books to finish ASAP, once I am done I will execute your provided lists literally.Currently I am in Stone mountain, lakewater block.

I am looking to buy the ugly duck on the block that can grow equity and have stable cash flow- about $500/month.

You have to either get lucky, have an unfair advantage, or do the necessary blocking and tackling to find situations that create deals.

I want to contact the owners of tax deeds /pre foreclosure before they hit the auction block.

It's doable as a market to do what you want, but you must understand the block dynamics if you are going for Chicago proper.

How can I unsub or block these annoying emails?

If you can find a very similar property (properties) within a few blocks that is golden....but you will find that often there will be few, or sometimes none, within a close proximity.This is when your talent will come into play.

Experienced Detroit investors all know an investment should be done with a block-by-block strategy.

I'm also charging less than Rentometer suggests I should.There are a few equally nice units a few blocks away that charge comparable rent.
