And, all their communication is via text or email because they are "deaf".Now I get to field calls all day and all night attempting to verify the identity or legitimacy of this person's claims. 

I created two identical contracts and we signed both so she could keep one copy for her records.  

This is a purpose built up/down brick duplex from the 60's.Currently the property has two identical goodman 95% efficiency forced air furnaces (mfg 09') - so no duct-work needs run.

If you get a site tomorrow and a competitor gets one today... if everything else is exactly identical, he will outrank you!

Zero chance of that happening unless you committed some fraud. 70-80% will be the most you get.

They usually revolve around fraud and intentionally covering up problems.

In theory it makes sense, and if you have 2 identical, competing properties yes.

I used to manage a bank branch in a CRA neighborhood for US Bank, and I assure you that our lending standards were identical there as they were in wealthier areas.In short, banks were (and are) required to offer banking services, including loans and deposits, in low to moderate income areas, but no bank has ever been forced to make a loan to someone who they knew could not repay. 

(They wont pay if it was willful fraud though typically).Most blue states have something called the Guarantee Fund,  which is a fund that consumers can make claims against and get reimbursed from for the actions of licensees or require licensees to be bonded,Most red states dont have that, and a quick search and I cant find a Guarantee Fund for Florida, which I sort of expected.

Signing contracts with no ability or intention to close is FRAUD.
